Your energy needs determine how many panels you need, which affects the overall price of your solar system installation. To eliminate your electric bill entirely, you must generate 100% of the electricity your home needs. Most homeowners need between 25 and 35 panels to achieve complete energy independence.Average households need

A solar panel typically produces about one kilowatt-hour (kWh) per day, so if your daily kWh usage is 30, you would need 30 solar panels to generate all of your energy needs. If you need to generate extra energy to heat a pool or run the air conditioning for most of the year, this adds to your energy costs.

Some solar power calculations are based on a satellite photo of your roof and offer an estimate of how much electricity you can generate. Other calculators use your regional solar irradiation to create the estimate, while others use the size of your roof or your typical electricity consumption with no other factors included. Solar calculations may or may not include federal, state and local incentives that, if you’re eligible, can create significant savings.

For a more accurate calculation, try to factor in times when there is not as much solar power available, like when it’s cloudy or in the evening. There are two main ways to account for this:Battery backups can be used to bank power when it’s available and supply the required power when the sun isn’t shining. There are many different types of solar batteries available, so do some research to find the right one for your home.

Buyback agreements can help offset the cost of buying electricity from the utility company when your system isn’t producing enough power. If your solar energy system provides more electrical power than your home uses when the sun is shining, the utility company will pay you for that extra power at what’s called “avoided cost.” This rate is usually a little less than half of the cost the utility company charges for power.

The cost of solar panels has declined dramatically over the last decade, and solar systems now offer more value to homeowners than they ever have before.

In this article, we’ll take a look at why solar module prices have fallen so dramatically, the key terms for evaluating the cost of solar systems, and the many factors that will ultimately impact the price you pay for your solar system.

The cost of solar panels has declined substantially over the last decade as the industry has matured and reached production at the largest global scale.

Since 2010, solar panel prices have fallen by roughly 90% while global solar deployment has grown by over 400%, and this incredible growth rate along the entire global solar supply chain has dramatically reduced prices.

Just like computers, big-screen TVs, and cell phones, the economies of scale that solar panels now enjoy have produced a dramatic cost curve that has fundamentally changed the energy industry.

Utility-scale solar installations are now cheaper than all other forms of power generation in many parts of the world and will continue to replace older, dirtier power plants run on coal and natural gas.

Calculating the price per watt for a solar system is very straightforward — it’s simply the gross system cost (contract value) divided by the number of watts in the system.

Ultimately there are many factors that figure into the price per watt of a solar system, but the average cost is typically as low as $2.75 per watt. This price will vary if a project requires special adders like ground-mounting, a main panel upgrade, EV charger, etc.

Another measure of the relative cost of solar energy is its price per kilowatt-hour (kWh). Whereas the price per watt considers the solar system’s size, the price per kWh shows the price of the solar system per unit of energy it produces over a given period of time.

While price per watt is most helpful comparing the relative costs of solar bids, price per kilowatt-hour is mostly used to illustrate the value of solar relative compared to buying your power from the electric utility.

For example, the average cost of a solar system purchased through solar.com is 6-8 cents per kWh, depending on the size of the system, type of equipment and local incentives.

While electric bills are subject to continuously increasing rates, purchasing a solar system can be thought of as pre-paying for 25-years of power at a locked-in price, protecting you from decades of rate increases.

The payback period of going solar for the average US household is around 9-10 years. However, it can be much shorter for homeowners with higher than average utility electricity rates.

Comparing the cost per kWh of solar versus grid electricity is an easy way to estimate how much you can save by going solar. This figure is provided in quotes generated through solar.com

Let’s run through an example using a 6.4 kW system with a net price of $20,484 (after the 30% tax credit). Most solar panels are warrantied for 20-25 years and last much longer, so we’ll assume a 22 year lifespan to be super conservative. Finally, we’ll assume 90% efficiency over the 22 years.

There are other important state and local incentives that depend on location, such as New York’s 25% state tax credit and California’s SGIP program for solar batteries.

At the end of the day, going solar is a home improvement just like remodeling a kitchen or putting in new floors. As with any home improvement project, it’s crucial to get multiple bids to find the best price without sacrificing quality.

Hard costs for solar panel modules, inverters, and balance of system equipment increased by as much as 53% in 2021/2022 due to supply chain issues. These costs are expected to fall in the future as supply chains untangle and new tax incentives jumpstart American manufacturing of solar equipment.

Now that we understand how to evaluate the relative cost of solar systems and the factors that contribute to overall installation costs, let’s consider the big question: how much do solar panels cost to install on your home?

Solar energy system costs vary widely depending on many factors like the amount of energy needed, the amount of roof space available, the kinds of panels and inverters being used, and whether a battery is included with the solar system.

The average cost for a solar system is around $20-30,000 (before incentives), but the system size is proportional to the amount of power needed. Especially in places like California and New York, system payments are typically lower than the electric bill the homeowner is paying for anyway.

As a virtual platform, solar.com has been structured from the very beginning to have the lowest costs in the industry, as verified by the US Department of Energy.

Most companies rely on expensive marketing campaigns and in-home salespeople to sign up homeowners, which leads to an extremely high cost of acquisition for every system they install. By operating virtually, solar.com saves installers on those costs, and those savings are passed along to you!

Here is a direct comparison between average market pricing and solar.com’s average pricing in some of the largest solar markets in the country, according to data from the National Renewable Energy Laboratory.

Residential solar energy costs on average 6 to 8 cents per kWh when purchased through the solar.com marketplace. The cost per kWh varies based on the size of the solar system, sunlight, type of equipment, and energy needs.

To find the cost per kWh of solar energy, divide the net cost (after tax credit and rebates) by the lifetime output of the system (system size in kW x average peak sun hours per day 0.7 efficiency rating x 365 x 25 years).

One way to measure solar panel cost is in Price Per Watt (PPW). In California, the average PPW of a home solar system is between $3.00 and $4.00 per Watt.

With an average cost of 6 to 8 cents per kilowatt-hour through the solar.com network, solar energy is much more cost effective that grid electricity in most of the US. In November 2022, the average price of grid energy was 16.3 cents per kWh — more than double the average cost of solar energy purchased on solar.com.

Solar owners essentially replace their utility electricity bill with payments on their solar system. Once the solar system is paid off (typically over 5-10 years), solar owners no longer pay for electricity and enjoy a return on investment for the life of their solar system (typically 25 years or more).

Residential solar energy looks expensive as the upfront cost of a solar system is typically between $20,000 and $30,000 (before the 30% federal tax credit and state/local incentives). But when boiled down to cents per kWh, home solar energy is much cheaper than grid electricity in most areas.

The average cost of solar energy purchased through solar.com is 6 to 8 cents per kWh while the national average cost of grid electricity was 16.3 cents per kWh in November 2022.

Solar panels are typically warrantied for 25 years or more and pay for themselves after 5-10 years (depending on the size of the system and cost of local grid electricity). For many solar owners, that leaves 15-20 years of zero electricity costs adding up to tens or hundreds of thousands of dollars in savings.

The cost of solar energy has fallen dramatically over the last decade and federal and state incentives have made home solar systems more accessible to homeowners than ever before.

Knowing the key terms for evaluating solar system costs and the primary components of solar systems helps to understand the most important considerations that factor into the cost of solar systems.

A single solar panel costs between $2.67 and $3.43 to buy and install.4 The price of the whole system is based on its capacity, measured in watts. How big a system you need will be based on how much energy you use, your roof’s sunlight exposure and panel efficiency.

The average payback period for a residential solar system is between six to nine years, depending on the cost of your system, incentives and savings from your energy bill.19

These figures are based on the average 6.2 kilowatt solar system. The cost of each system will vary based on panel manufacturer, inverter option, location and equipment.

Maintenance of solar panels ranges from routine cleaning to major repairs. On average, households pay $150 for one solar panel cleaning.11 Companies charge between $3 to $10 per panel based on roof slant, home height and system size.11 Some firms charge a flat rate fee for a system cleaning. If you clean your system twice a year, as recommended, you can expect an annual bill of about $300.

If your system is damaged, you may incur additional expenses. Repairs to your system will include the prices of equipment and labor. Labor is typically priced at $100 per hour. Materials for solar repairs could be as little as $180 but may also be greater than $1,000. Your combined, total bill may range from $200 to $3,000.11

When you own your system, you are responsible for the cost of maintenance and repairs. Your warranty should cover specific system failures; contact your installer before you begin repairs. A Sunrun solar lease, lets you save thousands of dollars in maintenance and repairs. You simply pay for the power, and we take care of the rest. Our comprehensive service package features the Sunrun Guarantee, which includes best-in-class monitoring, free equipment replacement, and system repairs including parts and labor, and routine maintenance.

If you’re set on buying your own home solar system, you can also purchase our full-service package, Protection Plus. While the system is yours, we’ll give you the same comprehensive support that comes with our Sunrun Guarantee.

The price of your panels will depend on the manufacturer. Sunrun partners with LG, a world leader in solar technology and panels. Striking the right balance between quality, efficiency and affordability, LG offers some of the best solar panels on the market today.14

Another factor in determining your total home solar system cost is where you live. Here are the states with the lowest and highest average solar system costs:*

Just because a residential solar system costs more in a given state doesn’t mean it’s any less cost effective.5 Local incentives can make a huge dent in solar installation costs even in the most expensive states.

Going solar can reduce your utility bills—especially if you qualify for tax breaks and live in an area where solar panels are cheap. Homeowners with high electricity bills can potentially save tens of thousands of dollars throughout the lifespan of their system. However, you should still be prepared for a large up-front cost.

According to the Center for Sustainable Energy, the average cost for solar panels is $3–$5 per watt, totaling $15,000–$20,000 for a typical 5 kilowatt (kW) system. Learn which factors impact cost before reaching out to solar companies near you, plus get information about cost-saving tax credits and incentives.

Solar panel costs can vary widely from state to state, due in part to the average electricity bill in the area. Hawaii has the highest costs, while Louisiana has the lowest costs. The national average price is 10.53 cents per kilowatt-hour (kWh). Keep reading for a breakdown of solar panel costs in each state.

Solar installation is a straightforward process. Your solar company will handle most, if not all, steps. A representative will begin by holding a consultation to assess your energy needs and home design.

Matt Johnson, co-owner ofNamaste Solar, says that a reputable installer should supply an itemized list of the costs for each aspect of the installation, including labor, permit fees, sales taxes, utility fees, the interconnection fee, and so forth. The installer should also include available tax incentives.

Labor: Labor costs vary by location and are more expensive in areas with higher costs of living. Different solar providers also charge different prices. Labor will be included in your initial quote.

Location: Solar panels cost more in some states than others, largely due to electricity costs in the region. Peak sunlight hours are also also a factor.

Panel quality: The equipment you choose has a big impact on your electricity production. You’ll want to find the most efficient solar panels that fit your budget. More expensive equipment doesn’t always translate to higher savings, while the cheapest option can sacrifice value. Find the right balance between quality and price.

Solar tax incentives lower installation costs. These incentives are offered by the federal and state governments, utility companies, and certain municipalities. Some common types include tax credits, cash rebates, Solar Renewable Energy Credits (SRECs), and property tax exemptions. These incentives vary by state in terms of availability and payout.

One exception is the federal solar tax credit, which provides a tax deduction equal to 30% of your solar installation costs. If your tax liability is lower than the deduction, it will roll over to the next year.

Solar panel installation requires a significant financial commitment, so any companies offer different payment options to suit different budgets. Here’s an overview of the typical financial options offered by solar providers:

Full payment: You pay for the solar system outright without a loan or payment plan. This option will save you the most money because you won’t pay interest rates. Full payment also grants you ownership of your system, qualifying you for incentives.

Solar loan: A loan allows you to make small payments over a longer payback period. However, you’ll pay more in the long run due to interest rates. Solar loans also qualify you for solar incentives.

Solar lease: This option allows you to make fixed monthly payments with little to no up-front cost. Your solar company retains ownership of your system and is responsible for its upkeep. These agreements usually last around 20 years. Leasing customers don’t qualify for solar incentives.

Power purchasing agreement (PPA): A PPA allows you to pay for only the energy you use. Similar to an electric bill, the rate fluctuates each month. Your solar company retains ownership of the system and is responsible for its upkeep. You will not qualify for incentives.

Solar panels can save you money on your electric bills, but the amount depends on your roof’s size and angle,  local electricity rates, and how much direct sunlight you receive. Compare your monthly electric bills to your projected rate with solar panels to get a sense of how much you can save.

Solar panels are also cheaper than ever before. According to the Solar Energy Industries Association, the cost to install solar panels has dropped more than 70% in the past decade.

The number of solar panels you need will depend on a variety of factors, including the size of your home, the amount of daily sunlight it receives, and more. Ultimately, the energy needs will dictate how many panels you require. You’ll need your solar panels to generate 100% of your home’s electricity needs to completely get rid of your electricity bill.

The typical solar panel produces roughly one kilowatt-hour per day. You can find out your kWh usage on your utility bill. It will be listed monthly, so divide it by 30 to get your daily use. If you use 50 kWh, you would need 50 solar panels. But there are other features outside your home that might require energy, like powering a guest home or heating a pool. That will increase the number of solar panels you need. Johnson says that certain issues with your roof can also increase installation costs, such as additional lumber to strengthen rafters.

It’s important to do your research on the best solar providers and equipment before investing in solar panels. You should also maximize any federal and state incentives whenever possible.

We recommend getting as many quotes as possible to get the best rate and avoid inflated prices. Weigh the equipment’s cost, financing options, and warranties. Use our tool below to begin your search for solar providers in your area.

Solar panels can save you money by reducing or even eliminating your energy bills. They increase your property value, giving you substantial return on investment and increased profit if you sell your home.

The amount of solar panels needed to power a house depends on the amount of daily sunlight your home receives, the types of appliances you have (electric vs. gas), the size of your roof, and more. Homeowners should consult an expert to ensure they get the right amount of coverage for their house.

No, solar panels do not generate power in the dark. However, solar panels can continue to provide power due to net metering—surplus power is transferred to the public utility power grid to offset the costs. You can also buy a solar battery that stores excess energy to use at night.

Net-metering is a billing system that compensates residential solar customers for excess energy. This energy is sold back to the grid in exchange for credits on your future utility bills or an annual payout, depending on the program. Net-metering policies are offered at the state level or through utility companies.

Quality solar panels can last 25–30 years, or even longer with regular maintenance and servicing. Your panels will continue to work beyond this time frame but their energy production will drop significantly.

Yes, a house can run on solar power alone with an excellent solar system and power storage options. However, you will need to invest in a high-quality system and panels, which requires a significant financial investment.

The rising cost of electricity from traditional sources and government incentives to go green make the idea of installing solar panels more attractive for many homeowners.

On average, solar panel installation and the system together can run from $15,000 to $25,000, according to the latest information from theCenter for Sustainable Energy.

Before you make the leap, learn how yourelectric bill, location and incentives can impact your wallet over time. Here are five steps to take to determine whether you’ll save more than you spend on solar panels.

Solar panels generate their own power and can therefore greatly offset your monthlyelectricity bill, if not eliminate it. The higher your bill, the more likely you"ll benefit from switching. But be aware that electricity rates and usage — the main charges on your statement — are volatile.

"If a utility’s electricity prices fluctuate, so could the amount of savings," says Garrett Nilsen, deputy director for the U.S. Department of Energy"s solar energy technologies office. "Similarly, if energy consumption changes, the amount of savings can also vary."

More sun means more energy produced and a greater potential to save with solar. Certain states, like Arizona and California, average more sunlight hours per day.

Your home"s orientation toward the sun, the amount of shade it gets, and its roof type also affect a solar system"s output. You can estimate the efficiency of panels on your home using theSolarReviews calculator.

When calculating the total price, consider how much energy you regularly consume — your usage is listed on your monthly utility bill — and what size system will generate the amount needed. Some tools, like the SolarReviews calculator, estimate the system size for you.

Then comparison shop for solar panels as you would other big-ticket items, such as a car or TV, says Vikram Aggarwal, CEO of the solar marketplace EnergySage. Some companies reduce installation costs through rebates and other programs.

Aggarwal recommends getting quotes from three to five contractors. EnergySage compiles solar companies’ customer reviews, certifications, Better Business Bureau profiles and other information to help you find reputable providers.

A federal law passed in 2022 incentivizes consumers to make clean energy enhancements, like installing rooftop solar. A substantial update to an existing energy-related tax break that was set to expire at the end of 2023, the Residential Clean Energy Credit allows taxpayers who have solar (and other approved clean energy equipment) installed to recoup 30% of the cost in the form of a federaltax credit.

What that means:A solar setup that costs $15,000 would yield a $4,500 credit (30% of $15,000) that you can take advantage of come tax time to reduce any federal taxes owed. The credit isn"t refundable though, meaning any money left over after your full tax bill is covered won’t be paid out to you. But you may be able to apply the remainder of the credit toward taxes owed in subsequent tax years.

Depending on your state, you may receive extra incentives like cash back, property tax exemption, waived fees and expedited permits. In some states, homeowners with solar panels can sell excess power to their local utility companies. Look up credits available in your state by reviewing thedatabase of state incentives for renewables and efficiency.

Changes in government trade policy also impact prices. There have been varying tariffs on imported solar cells and panels over the last decade affecting costs and supply. For example, tariffs resulted in a 16-cent-per-watt increase for the average consumer in 2018, which translated to an overall increase of $960 for a 6-kW system, according to EnergySage.

If you live in an area with high energy rates and a suitable solar rating, and if you can afford the initial investment, it’s worth installing solar panels on your home while the 30% tax break is in place — for the good of the environment and your wallet. But don"t expect to eliminate your power bill overnight.

If you decide to purchase solar panels, shop around and search for incentives. Consider financing with a solar loan if you’d rather spread out the cost over time. Keep in mind that you don’t have to buy solar panels — you can lease them, too. Leasing offers a lower upfront cost, though since you don’t own the panels, they won’t raise the value of your home, and you may not be eligible for incentives.

Saving money is smart. Going solar is a smart investment. Everyone asks about cost, but if your goal is to maximize how much you make from your investment, then the most important questions are “how much money will you save each month on electric bills?” and “how quickly does your solar system pay for itself?”

To calculate that payback period, you need to account for factors like the quality of your solar system, how much sun reaches your solar panels, whether you lease or own the system, the cost per watt, available tax credits, and quite a few more. Reputable solar providers can calculate those factors to show you how quickly your system will pay for itself in electric bill savings.

But understandably, you want to know how much it will cost to put a solar system on your roof. Below we"ll break down cost and some of the other major factors that you should consider.

One of the first questions someone interested in home solar asks is, "How much do solar panels cost?" It’s important to know there is not a one-size-fits-all answer because every home is different, and there are many geographic variables and federal and local tax incentives to consider.

The easiest thing to do is to contact a professional solar installer. The installer will give you a free evaluation that entails looking at your electricity bill to find out how many kilowatt hours of electricity your household typically uses and evaluating your roof and shading, to determine how many panels you’ll need. That, combined with local solar incentives your community may offer and the federal solar tax credit,* will give you a full picture of how much your home solar system will cost. The good news is that no matter where you live, the cost of solar panels is coming down.

We look at the price per watt when figuring out the cost of your system, but you may find it more useful to think about the price of leasing a solar system separately from the price to own one. That"s because with a lease it"s important to think about how much you can save for each month of the lease, but when you own the system it"s more important to understand how quickly it can pay for itself.

Very few people are going to buy just the solar panels themselves, just like few people would buy the components of a car and build their own vehicle. We recommend you use a SunPower-approved installer for your solar system.

Yes, it’s possible to buy a single solar panel for as little as $100, but a solar panel does not operate in isolation. You need a system of hardware and software to generate electricity from the sun, including solar panels, an inverter, mounting hardware, wires and cables., It is also beneficial to have a monitoring system that tracks the production, energy use and savings of your system. And you need to consider the cost of installation and operation.

Once you get an estimate for the cost of your solar system, you should subtract the potential savings on your utility bill over time, including any incentives offered by your local or state governments. Then you’ll have a better understanding of how going solar will impact your finances.

To help you understand the price of going solar in your area, we"ve analyzed SunPower price quotes, as well as quotes gathered by third-party sources for thousands of homeowners across the country. *

We found that the cost of installing a 5 kW solar system in the U.S. ranges from $11,150 to $46,100, or in other words, from $2.23 to $9.22 per watt. And that"s before considering the benefits of any available tax credits or incentives.

The more direct sunlight your home receives, the more power the panels can produce. But there’s a little more to it than just sunlight. To see if your house is a good candidate for solar, try out a solar panel suitability checker such as Google"s Project Sunroof. Then set up an appointment for a solar consultation with an expert who’ll visit your home to inspect its orientation (solar panels facing south capture more energy), roof angle and tree shading to see if your roof will receive enough sunlight to meet your family"s electricity needs. SunPower"s solar consultations are free, online or in-person, and you can learn more about your home electricity needs and savings options.

It"s also important to know a SunPower Equinox® solar solution has unique, factory-integrated microinverters in each panel. Meaning, if one panel isn"t producing energy because of shade, neighboring panels receiving more sunlight can still generate solar energy for your home.

Remember that the adage, “You get what you pay for,” applies to home solar technology. Not all solar systems are alike. The quality of the technology matters in the long run. The durability, reliability and efficiency of solar panels can vary widely by manufacturer. If you settle for a conventional home solar system that might cost less out-of-pocket, you can expect to see average (or below average) results and less savings over time. Watch these videos about the lifespan of SunPower® solar panels and their durability and reliability.

In short, SunPower panels are the most efficient home solar panels you can buy.* A higher quality panel like SunPower’s might cost a little more upfront, but you’ll see a higher—and quicker—return on your investment in the long run. Our panels come with a 25-year Complete Confidence warranty and have an expected useful life of 40 years.* And since they’re more efficient than other panels on the market, you’ll need fewer of them on your roof. Our panels produce up to 55% more energy in the same space over 25-years than conventional panels,* ultimately saving you more money on your electric bill.

Industry measurements such as the Fraunhofer Center for Sustainable Energy Systems’ PV Durability Initiative can give you a better idea of a solar panel’s expected lifespan—a factor that can have a tremendous impact on the system’s lifetime value.

The superior efficiency and durability of high-quality panels can provide increased savings over time and lower maintenance costs. You can get a personalized SunPower solar savings estimate using our solar calculator, which lets you factor in variables like buying solar + storage and/or having an electric vehicle.

There are many different tax incentives, subsidies and financing and billing solutions at the state and local levels that can make going solar more affordable. To see if you might be eligible for renewable energy incentive programs, visit the Database of State Incentives for Renewables & Efficiency (DSIRE®).

If you purchase your solar system, you may qualify for the 26% federal tax credit (ITC).* The full solar ITC is available to home solar owners through 2022. It drops to a 22% credit in 2023 and is scheduled to go away completely in 2024, so don’t put off buying solar for too long.

Ultimately, the easiest way to answer the “How much does solar cost” question is to give our solar advisors a call at 844-578-6793. They’ll help you get a free estimate for your home. Or you can contact a solar installer in your area directly. Get more tips on Choosing a Home Solar Installation Company.

When you’re getting solar estimates, be sure to ask about the technology the installer intends to use, their hardware, their monitoring software, their past installations and their maintenance plans. It’s especially important to ask about their warranty.

Most solar companies offer multiple, separate warranties for each component on a solar system, and there can be hidden fees like shipping fees when replacing a broken panel. With SunPower Complete Confidence Warranty, one company backs your entire solar system, including battery storage and monitoring.

Power generation from solar PV increased by a record 179 TWh in 2021, marking 22% growth on 2020. Solar PV accounted for 3.6% of global electricity generation, and it remains the third largest renewable electricity technology behind hydropower and wind.

Solar PV electricity generation achieved another record increase in 2021; however, greater effort will be needed to get on track with the 2030 milestones under the Net Zero Scenario

China was responsible for about 38% of solar PV generation growth in 2021, thanks to large capacity additions in 2020 and 2021. The second largest generation growth (17% share of the total) was recorded in the United States, and third largest in the European Union (10%). Solar PV proved to be resilient in the face of Covid-19 disruptions, supply chain bottlenecks and commodity price rises experienced in 2021 and achieved another record annual increase in capacity (almost 190 GW). This, in turn, should lead to further acceleration of electricity generation growth in 2022.

However, reaching an annual solar PV generation level of approximately 7 400 TWh in 2030, aligning with the Net Zero Scenario, from the current 1 000 TWh requires annual average generation growth of about 25% during 2022-2030. Although this rate is similar to the average annual expansion recorded in the past five years, it will require increased effort to maintain this momentum as the PV market grows.

Utility-scale plants were responsible for 52% of global solar PV capacity additions in 2021, followed by the residential (28%) and commercial and industrial (19%) segments. The share of utility-scale plants was the lowest since 2012, as generous policy incentives drove record distributed PV capacity additions in China, the United States and the European Union in 2020-2021.

In the environment of increasing fuel and electricity prices in 2021, distributed PV became an increasingly attractive alternative for many consumers, which has driven investment. Utility-scale PV remains the most competitive source of PV generation in most parts of the world; however building large-scale installations is becoming increasingly challenging in many parts of the world due to the lack of suitable sites.

Increased support for all segments will be needed to get on track with Net Zero Scenario milestones, reaching annual solar PV capacity additions of about 600 GW to correspond with the 2030 capacity level. Distributed and utility-scale PV need to be developed in parallel, depending on each country’s potential and needs.

Crystalline polysilicon remains the dominant technology for PV modules, with over 95% market share. The shift to more efficient monocrystalline wafers accelerated in 2021, with the technology capturing almost all crystalline PV production. In parallel, more efficient cell design (PERC) is also expanding its dominance with almost 75% market share. New, even higher-efficiency cell designs (using technologies such as TOPCon, heterojunction and back contact) saw expanded commercial production and captured about 20% of the market in 2021.

Policy support remains a principal driver of solar PV deployment in the majority of the world. Various types of policy are behind the capacity growth, including auctions, feed-in tariffs, net-metering and contracts for difference. The following important policy and target changes affecting solar PV growth have been implemented in 2021-2022:China published its 14th Five-Year Plan in June 2022, which includes an ambitious target of 33% of electricity generation to come from renewables by 2025 (up from about 29% in 2021), including an 18% target for wind and solar technologies.

In July 2021 the European Commission proposed to increase the bloc’s renewable energy target for 2030 from 32% to 40%. The proposed target was further increased by the REPowerEU Plan to 45% in May 2022 (which would require 1 236 GW of total installed renewable capacity, including 600 GW of solar PV). Many European countries have already expanded their solar PV support mechanisms in order to accelerate capacity growth with a view to the 2030 targets and in response to the energy crisis caused by Russia’s invasion of Ukraine.

During COP26, held in November 2021 in Glasgow, India announced new 2030 targets of 500 GW of total non-fossil capacity and 50% renewable electricity generation share (more than double the 22% share in 2020), as well as net zero emissions by 2070, with solar PV being one of the main technologies used to achieve these goals.

Beyond global renewable energy initiativesthat include solar PV, there are numerous international organisations, collaboration programmes, groups and initiatives aimed at accelerating solar PV growth around the world, such as:The IEA Photovoltaic Power Systems Technology Collaboration Programme, which advocates for solar PV energy as a cornerstone of the transition to sustainable energy systems. It conducts various collaborative projects relevant to solar PV technologies and systems to reduce costs, analyse barriers and raise awareness of PV electricity’s potential.

The International Solar Alliance, which is a treaty-based intergovernmental organisation that provides a platform to promote solar energy across 86 member countries in a safe, affordable, sustainable and equitable manner.

The private sector’s main activity in solar PV deployment can be divided into two categories:Companies investing in distributed (including rooftop) solar PV installations on their own buildings and premises – responsible for almost 30% of total installed PV capacity as of 2021.

Companies entering into corporate power purchase agreements (PPAs) – signing direct contracts with solar PV plant operators for the purchase of generated electricity. Solar PV plants dominate renewables PPAs, with a share of almost 75% in 2020.

Lengthy and complicated permitting processes are one of the main challenges to the faster deployment of utility-scale solar PV plants in many parts of the world, especially in Europe. Establishing administrative one-stop shops, developing clear rules and pathways for developers applying for a construction permit, determining strict timeframes for application processing, and public engagement in the identification of land suitable for investment could significantly accelerate solar PV deployment.

Distributed solar PV expansion, driven by rapid cost reductions and policy support, is transforming electricity markets. Currently, some distributed solar PV policies can have undesirable effects in the long term, disrupting electricity markets by raising system costs, challenging the grid integration of renewables and reducing the revenues of distribution network operators. Tariff reforms and appropriate policies will be needed to attract investment into distributed solar PV while also securing sufficient revenue to pay for fixed network assets and ensuring that the cost burden is allocated fairly among all consumers.

While dramatic scale effects have been achieved in solar PV, R&D efforts focused on efficiency and other fundamental improvements in solar PV technology need to continue to get on track with the Net Zero Scenario. Public support for R&D in solar PV technology can be an important factor in achieving further efficiency gains and costs reductions.

Higher PV shares, particularly in distribution grids, necessitate the development of new ways to inject power into the grid and to manage generation from solar PV systems. Making inverters smarter and reducing the overall balance-of-system cost (which includes inverters) should be a key focus of public R&D support, as they can account for 40-60% of all investment costs in a PV plant, depending on the region.

The price of solar energy has dropped dramatically over the past two decades. Between 1998 and 2009, the cost of installed solar dropped by 30 percent. And since 2010, the cost of installed solar has dropped a further70 percent.

Today, building a new utility-scale solar plant is far less expensive than building a new fossil fuel-burning power plant of equal capacity. This drop in solar costs is due to a variety of factors, including:

New manufacturing techniques have been a major driver behind the decline in solar prices. The past 20 years have seen the development of more compact and efficient panel designs that require fewer resources overall. These innovations enable manufacturers to save money and pass those savings on in the form of lower prices.

Declines in manufacturing costs have also led to cheaper, more affordable panels. China, in particular, has made massive investments into all sectors of the solar industry over the past 20 years.

Chinese solar panel makers benefit not only from generous government subsidies, but also from low labor costs: the average wage in China is about$3.60 per hour, while the average wage in the U.S. hovers around $21 per hour.

This confluence of low labor costs and government investment has led to China’s rapid growth as an industry leader. Analysts credit the80 percent decline in global panel prices that occurred between 2008 and 2013 to the rapid growth of the Chinese solar industry. Today, six of the top 10 solar manufacturers are Chinese, andtwo-thirds of all solar panels are now made in China.

But these low panel costs have also frustrated domestic solar manufacturers. Some have argued that cheap foreign panels, especially those from China, have made it impossible for American manufacturers to compete. SunEdison, for instance,filed for bankruptcy in 2016, and Suniva filed for bankruptcy in 2017. Shortly thereafter, Suniva and another panel maker, SolarWorld,filed a petition with the U.S. International Trade Commission arguing for tariffs on imported solar panels and annual limits on the number of imported panels. The president will decide how to pursue the case later this year.

Soft costs － the costs that are not directly associated with the purchase of solar panels, inverters, and other equipment － have also declined dramatically over the past 20 years.

Some of these declines are due to increases in corporate efficiency. The internet, for instance, has made marketing and customer acquisition much easier than it was back in 1998 (though the industry stillrelies heavily on door-to-door salespeople to increase sales of residential solar).

Panel prices have remainedrelatively flat since 2012, and analysts believe that in the U.S., most of the future reductions in the price of rooftop solar installations will come from declines in soft costs, which constituted67 percent of the costs associated with installing a residential solar system last year.

In 2011, the Solar Energy Technologies Office (SETO) at the U.S. Department of Energy launched theSunShot Initiative, an effort aimed at making solar energy competitive with traditional electricity sources, without subsidies, by 2020. To that end, SETO worked to streamline permitting processes, collaborated with partners in industry and research labs, and poured millions into improving solar cell technology and manufacturing systems.

Similar programs exist in most of the developed world (and some of the developing world, too). Despite some recentbackwards motion, the U.S. and the global community have generally been interested in promoting the growth of solar and other renewables as a means to combat climate change.

Federal, state, and localfinancial incentives have also helped make solar more affordable. The most generous incentive is the federal government’s renewable energy investment tax credit (ITC). Introduced in 2005 and extended in 2015, the ITC allows homeowners to claim a tax credit equal to30 percent of their solar energy system. In other words, a $20,000 system would qualify you for a $6,000 tax credit.

The more solar panels there are, the better manufacturers become at making them, and the cheaper they become to ship. Analysts have even developed an explanatory model, Swanson’s law, to explain the phenomenon. According to Swanson’s law, whenever the production and shipment of solar panels doubles, panel prices drop by 20 percent. The effect is cyclical: as costs decline, the number of people for whom solar is a viable, affordable possibility increases, which further depresses panel prices. (We might now be in a post-Swanson era. As mentioned above, panel prices have leveled out since 2012 even as panel installations increase; price reductions since then have been primarily due to declining soft costs.)

But while solar has become far cheaper than it used to be, a residential solar system remains a substantial investment. Most people can’t afford to pay $15,000 to $25,000 out-of-pocket for solar energy.

Instead, most solar customers lease their systems ortake out a loan in order to cover for the cost. Greateraccess to financing options has helped increase the number of installed solar panels, which in turn has led to lower costs.

Most people take out home equity loans to finance their panels. Others might choose to take a loan directly from the solar installer, which often partner with financial institutions to streamline the purchasing process. Property assessed clean energy (PACE) loans － currently available in 31 states and the District of Columbia － allow homeowners to take out a loan against their house, then repay it as an added line item on their taxes. And if all else fails, homeowners might choose to take out a personal loan to cover their investment.

According toPowerScout, a Californian solar startup, the price of solar will continue to fall 4.4 percent each year through 2022. But if you’re interested in going solar, don’t wait; the renewable energy investment tax credit － currently at 30 percent － isset to decline to 26 percent in 2020, then 22 percent in 2021. After that, unless Congress approves an extension, the tax credit will be eliminated entirely for residential solar installations in 2022.

5 kW solar systems are near the average size for solar panel installations in the United States, so for those wondering how much solar will cost to install, looking at some price data for 5,000 watts of power is a good place to start. Prices will vary based on the size of your system, the type of equipment you choose, and the state that you live in. Learn more about how much solar panels cost, how much electricity a 5kW system can produce, and the smartest way to shop for solar.

As of January 2022, the average cost of solar in the U.S. is$2.776per watt ($13,850 for a 5 kilowatt system). That means that the total 5kW solar system cost would be$10,249after the federal solar tax credit (not factoring in any additional state rebates or incentives).

We looked at data from the EnergySage Solar Marketplace, the leading comparison-shopping platform for homeowners who are considering home solar panel systems, to find out just how much solar shoppers are paying for 5kW solar energy systems in different states across the U.S.

The prices listed below have not had the 26 percent federal tax credit for solar deducted. Depending on where you live, you might have additional state or local solar incentives and rebates that reduce the price even more. You may even be able to earn extra income by selling your system’s solar renewable energy certificates (SRECs).

Even if there are no other incentives where you live, comparing multiple offers from solar companies is important to ensure that you’re finding the best deal. Homeowners who register their property on EnergySage save up to 20 percent just by shopping around for the right option for their home.

From the table, there’s a lot to take away if you’re a U.S. homeowner. The bottom line is that you can never assume where solar will be affordable because even rainy Washington is one of the best states for solar power. Remember, the cost of solar depends on a lot of factors, so these numbers are just meant to be a starting point. In most cases, you should be able to find a 5kW solar system in this price range – if you receive offers from solar companies that are much higher or lower, be sure to ask follow up questions. Solar financing options can be a lot to learn in a short period of time for new solar shoppers so make sure to read up on various options so you can understand your potential for savings, payback period and energy offset.

The amount of electricity your solar panels produce depends on many factors, including the direction and angle of your roof. The most important one is how sunny it is where you live – for example, a 5kW system in Las Vegas makes about 30 percent more electricity in a year than one in Philadelphia. That being said, you don’t have to live in the Southwest for solar to make sense for you. The cost of electricity where you live is the biggest determinant of your solar savings.

The table below shows average estimated electricity production numbers for 5kW solar energy systems in cities across the U.S. By comparison, the average household in the U.S. uses 893 kilowatt-hours (kWh) a month, which equals 10,715 kWh per year. We estimated these numbers using a tool developed by the National Renewable Energy Laboratory called PV Watts.

As with any big ticket purchase, shopping for a solar panel installation takes a lot of research and consideration, including a thorough review of the companies in your area. A recent report by the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) recommended that consumers compare as many solar options as possible to avoid paying inflated prices offered by the large installers in the solar industry.

To find the smaller contractors that typically offer lower prices, you’ll need to use an installer network like EnergySage. You can receive free quotes from vetted installers local to you when you register your property on our Solar Marketplace – homeowners who get 3 or more quotes can expect to save $5,000 to $10,000 on their solar panel installation.

The bigger isn’t always better mantra is one of the main reasons we strongly encourage homeowners to consider all of their solar options, not just the brands large enough to pay for the most advertising. A recent report by the U.S. government found that large installers are $2,000 to $5,000 more expensive than small solar companies. If you have offers from some of the big installers in solar, make sure you compare those bids with quotes from local installers to ensure you don’t overpay for solar.

National-scale installers don’t just offer higher prices – they also tend to have fewer solar equipment options, which can have a significant impact on your system’s electricity production. By collecting a diverse array of solar bids, you can compare costs and savings based on the different equipment packages available to you.

There are multiple variables to consider when seeking out the best solar panels on the market. While certain panels will have higher efficiency ratings than others, investing in top-of-the-line solar equipment doesn’t always result in higher savings. The only way to find the “sweet spot” for your property is to evaluate quotes with varying equipment and financing offers.

Solar panels have enjoyed a meteoric rise in popularity in recent decades. That’s thanks in part to an increase in environmentally responsible behavior and the desire to reduce energy bills by exchanging traditional sources of heating, cooling and electricity with cleaner, more natural sources. If you’re thinking of making this switch, you’re probably wondering how many solar panels it takes to power a house.

While the answer can be a bit complicated, if you hire a professional or solar panel installation company to consult with, they’ll likely handle this part of the process as well (and may give you tips on how to maintain and clean solar panels).

But if you’re wondering how many solar panels you may need, and you’d like to take a stab at calculating it yourself, you’ll need a few pieces of information: how much energy your household uses; how much space you have on your roof that can be used for solar panel placement, how many hours of sun your home gets and the wattage and relative efficiency of the photovoltaic (PV) solar panels you’ll be installing.

In order to learn how many solar panels are needed to power a house, you’ll use a formula with three key factors, according to EnergySage: annual energy usage, panel wattage and production ratios. But what does that mean exactly?

When choosing the best solar panels you may think they look mostly the same, but they aren’t exactly created equally, so you’ll need to know the wattage of the panels you’re hoping to install. The panel wattage is the amount of electricity emitted from the panel. Most solar panels range between 250 to 400 watts of power, so it’s safe to assume 300 is the average panel wattage you might find.

According to EnergySage, a solar panel system’s production ratio is the ratio of the estimated energy output of a system over time (in kWh) to the actual system size (in W). You might think that this would be a 1:1 ratio – that you get out what goes in. But variations in the amount of sunlight that beams down on your home cause that not to be the case.

That equates to about 20 to 25 solar panels to do the job. You can use this same formula to determine how many solar panels you’ll need to power your home. Or, you can use the easier route, which is to look at your energy bill to determine what you’ll need.

Is there anything else to think about outside of the above calculations? Turns out, there are a few other things factors need to consider when determining how many solar panels to power a house.

Your solar panels won’t draw the sun’s energy at top capacity all the time. Think of those three-day bouts of rain that come in the fall, or large snowfalls in the winter that take several days to melt. Those are times you’ll need a buffer in your energy usage, so it’s recommended to have about 25% more solar panels than you need.

The amount of energy you’ll get from your solar panels is directly related to how much sun your home gets. More panels will be required if you live in an area without long hours of strong sunshine.

Most solar panels range in wattage from 150 to 350 watts per panel. If you choose lower wattage panels, you’ll need more in order to generate enough energy for your home. Of course, that’s assuming you’d like to replace 100% of your energy usage with solar energy. If you’re only hoping for a partial conversion, the difference in solar panel wattage may not matter as much.

To understand how many solar panels you’ll need, you must know the standard sizes of solar panels to know how many you can place on your roof. The area of a residential 60-cell solar panel is 17.62 square feet, and the area of a commercial 72-cell solar panel is 21.13 square feet. Solar panel installation companies will measure the area of your roof to determine how many panels can be installed safely.

Between 2008 and 2013, China’s fledgling solar-electric panel industry dropped world prices by 80 percent, a stunning achievement in a fiercely competitive high-tech market. China had leapfrogged from nursing a tiny, rural-oriented solar program in the 1990s to become the globe’s leader in what may soon be the world’s largest renewable energy source.

“They fundamentally changed the economics of solar all over the world,” said Amit Ronen, director of the Solar Institute of George Washington University, one of many scholars following the intense competition in the emerging $100 billion industry that supports the world’s growing solar energy demands.

China’s move eclipsed the leadership of the U.S. solar industry, which invented the technology, still holds many of the world’s patents and led the industry for more than three decades. Just ho
