The main component of a solar panel is a set of solar cells. A typical residential PV panel consists of 60 or 72 cells to produce about 320W. However, this isn’t the only layer of the ‘solar sandwich’.

In a solar cell, crystalline silicon is sandwiched between conductive layers. Each silicon atom is connected to its neighbors by four strong bonds, which keep the electrons in place, so no current can flow. Here"s the key: a silicon solar cell uses two different layers of silicon.

The mobile electrons are collected by thin metal fingers at the top of the cell. From there, they flow through an external circuit, doing electrical work, like powering a lightbulb, before returning through the conductive aluminum sheet on the back. Well, that’s it – the physics behind solar magic.

We offer solar panels for sale by well-known brands such as Canadian Solar, Hanwha Q CELLS USA, MISSION SOLAR, Panasonic Eco Solutions, and Solaria. They come in different energy production capacity, weights, sizes, and prices. Please contact our specialists to help you buy solar panels.

After installing solar panels on the rooftop of your house or cottage, you will isolate yourself from energy price fluctuations and voltage drops. Once you have paid off your solar panels and their installation, you can forget about the traditional energy sources for at least 25 years.

Monocrystalline silicon is created in specialized growth vacuum furnaces. Due to its purity of 99.99%, energy efficiency is much higher than of polycrystalline panels. This type of solar panels is most appropriate for marine vessels, RVs – or any places with limited installation space. Homeowners also buy solar panel of this type for their home installations.

The main advantage of polycrystalline solar panels is their affordable price. In cases when the maximum generation of energy from 1 Watt is not the main goal, installation of affordable solar panels is the best option. Polycrystalline panels are made of a large number of crystallites of different sizes and orientation. They are not as efficient as monocrystalline modules, but lately that difference in efficiency is quite small. Affordable solar panels work best for residential houses and large commercial buildings or factories.

To understand the number and efficiency of solar panels you need to make your house completely energy independent, there are few factors that you need to consider:

Let us assume that the electricity consumption of a house is 300 kWh per month. By dividing this value by 30 days and 7 hours of active work of solar panels per day, we get 1.42 kWh. You will always need to add 40% loss on battery and an inverter to the resulting number. This way, to provide a small house with electrical energy in the summer, you will need an array of solar panels with a capacity of 2 kWh. In order to receive enough electricity in spring and autumn, it is better to increase the array by 50%, or by another 1 kWh.

The most popular solar panels among our customers are 300 W solar panels. We offer solar panels ranging from 290 Watt to 360 Watt at competitive prices.

There are lots of brands that offer high quality PV solar panels for sale today. When choosing manufacturers and components for our products, we prefer the newest technological developments. That is why the solar panels and their components we offer are highly efficient. When buying solar panels, pay attention to the following solar panels for sale:

Panasonic PV modules have 27% higher power density compared to other brands. That allows generating 19.7% more energy from 1 m² (11 ft²). Panasonic solar panels cost slightly more than alternatives, but perform better, are more reliable, and have a much better warranty.

Canadian Solar produces highly mobile, compact and flexible self-sufficient solar power stations. They are 11% more efficient compared to other modules. They also have excellent efficiency under low light conditions – up to 97%.

Q CELLS solar panels may not offer industry-leading efficiency (around 18%) or performance, but their price-quality ratio makes them a good option for many homeowners who are planning to go solar.

JA Solar has made strong investments into PERC cell technology, ensuring higher performance warrantied for 83.1%. A very strong performance warranty and a relatively low solar panel price is a good reason to opt for JA Solar.

Trina Solar has a solid reputation and large global distribution network across 30 countries. Trina offers a range of solar panels incorporating many of the latest cell technologies, including bifacial, half-cell, dual glass, PERC, and N-type mono-crystalline cells.Read All

All these features enable integrators, installers, maintenance staff, and system owners to improve the site performance, assure the yield of the system, maximize solar power harvesting and reduce maintenance costs by increasing system up-time and resolving faults more effectively.

The world of solar energy is rapidly expanding. Alongside the exponential growth of technology in general. New innovations in solar power and technology are poised to make impacts on the future of renewable energy. But many of these technologies, like an app to monitor solar panels, are much more accessible than you think. You solar panel data in the palm of your hand.

In such a connected society, it’s no surprise that solar customers would want to have an up-close-and-personal relationship with their solar energy systems. Our smart phones and watches have allowed us to track, monitor, and analyze nearly any kind of personal data imaginable.

And your solar panels are no different. While solar panel monitoring apps may not tell you how many steps you’re taking or how many hours you’re sleeping, they can still provide valuable information. Like how much money you’re saving by going solar.

“The EMA APP is a mobile energy monitoring application designed to be used by owners of APS microinverter products. Users can check the real-time performance, historical power output, and environmental benefits of their PV system from their mobile device.” —APSystems

The Energy Monitoring & Analysis (EMA) App is one that many of our KC Solar customers love. It’s great for tracking their solar array performance in real time through their mobile devices.

Not only can you see a graphic representation of your solar panels and their individual performances. But you can also track your system’s output at a daily, weekly, monthly, yearly or even lifetime level.

“The monitoring platform provides enhanced PV performance monitoring and yield assurance through immediate fault detection and alerts at the module level, string level and system level.

No hardware or wiring is required to transmit data from the power optimizers to the inverter: the monitoring sensors and transmitters are built into the SolarEdge power optimizer and solar inverter, and measurement data is transmitted over the regular power lines.” —SolarEdge

The SolarEdge monitoring application is another popular app when it comes to tracking your solar system’s output and energy production. It’s also easy to access from any internet-enabled devices, including computers or tablets.

Key benefits of MySolarEdge include the robust reporting and analysis tools, which even gives users the option to schedule automatic reports. Plus, you can set up automatic alerts on any system issues.

In addition to having full visibility to your solar system’s performance — from a technical and financial perspective — MySolarEdge can even help customers detect excessive energy usage. Which can help you get in front of a bigger electric bill.

Enphase’s main solar monitoring application is web-based. Meaning it’s meant to be viewed from a desktop or laptop computer. But they recently launched a mobile app which is able to do many of the same actions. And help customers monitor their solar system from the palm of their hand.

See how much energy you’re consuming and storing, and check out each panel’s individual production. With a real-time, in-depth view of your solar system, it’s easy for system owners to make informed choices about energy use.

“The Fronius Solar.web App is the mobile version of the Fronius Solar.web online service. You can keep a constant eye on the energy yields of your PV system by simply installing the app on your iPhone, iPod touch, iPad, Apple Watch, Android smartphone or tablet. Use the Fronius demo systems for a sneak peek at what the application can do.” —Fronius

Even if you don’t have your iPhone on you, the Fronius Watch App can provide information about your solar system from your wrist. See your system’s current output, current consumption rate, and even the current state of charge. Not too bad for a watch screen!

The SMA Sunny Portal app prides itself on being a user-friendly option for solar system owners. With easy-to-understand reporting and desktop access as well as the app. Customers are able to find all the information they need about their solar panels.

From the “Plant Profile” page, customers can track and monitor their power, annual production, saved CO2, and more details about their solar systems. Functionality and data are prioritized in the user experience.

I have been looking for something like the SmartPV for a long time. There were a few products a while ago, but they sensed usage using a photo pickup to count the flashes on the main meter, and could be quite costly. This didn`t work for me, as my meter LED flashes irrespective of which direction the power is travelling! The development of directional clamp-on current probes that`s fixed this. Eventually I ended up with two Owl monitors, one of the mains supply and one on the PV feed. However, they were very fiddly and quite short lived (although I think I killed one by using lithium AA cells).

The SmartPV goes well beyond what I`d expected, particularly with its logging and analysis features. After I`d corrected my few stupid mistakes, it all seems to be working correctly. Very pleased so far. However, I am in a queue for a solar battery: that might cause an issue, but I`ll cross that bridge when I come to it.

This arrived the next day after I ordered it - I fitted and installed it in approximately 10 minutes. It instantly works, displaying electricity usage, solar PV generation, or the net of the two. `Does exactly what it says on the tin`. Five stars, I couldn`t find a solution online that did this easily without subscriptions or unnecessary complexity. I would happily recommend to anyone!

With a brand new solar PV and battery system, I purchased the Eco Eye monitor to independently check inverter readings, and as an easy to use visual display of grid import/export. With a direct feed to the solar/battery system from the meter box, I fully understood that I could only monitor the grid power (in/out) and the excess PV power flowing back to support the house load (ie PV less battery charging).

Setup was OK, and it all appears to work. However the display figure fluctuates rapidly, widely, and is often a good 100 watts different to both my smart meter and the Modbus grid meter. This is particularly so when the grid current is low or zero, which happens a lot as my inverter is set up to divert excess solar to the battery. The inverter clearly uses a feed-back loop from the Modbus meter, continually adjusting the battery charging to keep the grid current at zero, and I suspect that this generates noise that the Eco Eye picks up but that the Modbus meter and smart meter manage to avoid or integrate out. This was not unexpected, and the monitor route was by far the easiest and cheapest option for displaying solar performance in the house. However it does regrettably mean the unit is effectively unusable in my situation. I have now, finally and with considerable effort, managed to get the inverter data directly to a Raspberry Pi and Node-Red dashboard that I can view on my PC, but not as yet as a free standing, always on display. You win some, you lose some...

Needed something to replace my old Wattson which had given up the ghost and this was the ideal replacement. Have not experienced any issues with it but have two comments. One, it would be good to have it backlit as the display is not easy to see from a distance. Secondly, supporting software needs a revamp. The windows UI is a bit dated and clunky but operates fine. However, as a user of the the most recent Mac OS, I was unable to get the Mac version of the software to install no matter how hard I tried. Other than that vey pleased over all.

The eco eye and associated software is really great for monitoring energy usage, PV output, energy imported and exported. The charts show energy consumption and pv production very clearly and allow me to get a good handle on how to avoid exporting surplus PV. I will be using this to help me size a battery that will allow me to use all pv and also how much to load the battery overnight with cheap electricity.

It`s a good product. I had to replace a monitor installed with the Solar PV system, as the data collection function was being discontinued, and the Eco-eye more than replaces it. It was easy to set up and seems (so far) completely trouble-free. My only disappointment is that the software (a) doesn`t work under Linux, and (b) doesn`t seem to be able to dump the history data from the card via the USB connection -- otherwise fine.

We have found the EcoEye monitor to be an excellent product. It was straightforward for an amateur to install and it is easy to use. The fact that it is wireless means I do not have to go to the solar inverter to check on output. Switching between the different views - PV, consumption, PV minus consumption - is easy and useful. I would certainly recommend it to others.

It was fairly easy to set up once I had worked out which of our old cables was which. The display is really clear and I`m sure it has saved us money as we are much more careful about when we turn appliances on to make best use of the solar panels. I have never managed to make the memory card work - I had imagined that I would have some great spreadsheets showing our use over time, different times of day, solar vs grid, etc. But I don`t have any of that. The spreadsheet I managed to get out was fairly meaningless and the instructions didn`t really help. I should have asked for help from Eco-eye but never quite got round to it.

I purchased this product a few weeks ago, and although my PV meter is a long way from my supply meter, Eco Eye were more that happy to extend the cable for the CT clamp to 10 metres free of charge.

Setup was really simple and after only a week, I was getting excellent information on my electricity usage. I have quickly discovered that battery storage is not viable for me (I have had companies in giving quotes), so will be increasing the size of my solar array instead.

I found this product very easy to set up and within minutes it was providing me with the net production/consumption figure I wanted to see. I also have a second display in my office connected to my home-grown home automation system via a cable.

Thanks to the data being fed from the eco-eye, my home system is now able to divert excess power to electric radiators dynamically. The system monitors the house power situation along with things like room temperatures and makes decisions about switching on and off individual radiators. If the kettle is turned on, it switches off the heating immediately but if a cloud passes over it waits a minute before reacting. I am very pleased with the eco-eye products. They are doing exactly what I wanted; providing easy to read displays for me along with real time data to maximise my solar power and reduce my central heating costs.

I bought a eco-eye SmartPV moniota along with an additional display so I could see both generation and consumption at the same time. I was slightly puzzled when they both said exactly the same thing. But a quick call to the eco eye Tech team quickly sorted that out. I`ve got a Solar boost diverter (to heat hot water when I`m generating more electricity than I`m consuming) and it had kicked in. Which explained why both reading were the same.

I have an unusual situation where the PV panel feed enters the house on a separate consumer unit and 30m away from the mains power entry point. Eco-Eye were very helpful and advised that although this situation had not been tested, they felt sure it would work. In practice is works perfectly and the large transmission range of the unit means that I can have the display in any position in a very long house. With power readings recorded every 4 seconds, I now have the potential to do any analysis I want.

I needed a device that would give me information that I could download into a graphical format for future use. Especially, I needed some idea of my house base-load over a prolonged period, in order to help me make decisions on future home electrical installs. I also needed to see this data in relation to PV production, and PV export.

Downloads aside, I do find the the monitor very useful. It`s in the kitchen and at a glance I can see if my PV production is good enough to put on a load or two of washing, or baking and the like. I`m very pleased, it`s an excellent product.

Great product, but it isn"t quite as accurate as it could be. The unit gives an accurate reading when the solar generation is low, say 200w, but if this increases to anything above 500w, the device suggests that the house consumption is in excess of 1kw/hr despite few appliances running.

I downloaded the Manual, had a good read, and then installed the Trax software on Windows 10 Pro. And when I connected the Display to my PC with the USB cable, there it all was - Everything I wanted to see about instantaneous usage.

Solar panels sit on your roof for decades, silently making electricity from the sun, saving you money and saving the planet a little bit each day. Unfortunately, they’re also silent when they’re not making electricity, for example due to a wiring problem. To make sure your system is working properly, you need a way to check up on them.

Here’s our look at the best solar monitoring systems on the market. If you haven’t yet installed solar panels, this may determine your choice between installers, based on what solution they use. If you already have a solar installation but have no way to monitor it, this guide can help you choose a solution that’s right for you.

You can use solar monitoring to track your system’s performance over time, assist in troubleshooting various problems, track your solar investment’s financial performance, and give you peace of mind that everything is working as it should.

Each of these solutions uses hardware installed either on each solar panel or alongside a solar string inverter to record power flow, as well as software to keep a record of the flow over time - all while providing you with an interface to look up all the necessary data about your solar installation.

The solar monitoring solutions from the first two companies offer the same value proposition: module-level monitoring capabilities with a web portal and mobile app for convenient access to your solar production data. SMA does not currently support individual module monitoring, but does offer monitoring through both web and mobile platforms.

Enphase’s microinverters come with 25-year warranties, but cost more upfront than the others. SolarEdge systems that use a string inverter and power optimizers may be a little less expensive, but extending the inverter’s 12-year warranty (or replacing it when it fails) will cost extra. SMA’s central inverters are the least expensive, with 5-year standard warranties and available 20-year extended warranties available for an extra charge.

Enphase is perhaps the most popular solar equipment manufacturer in the world, setting the standard of the industry with their microinverter technology.

The small boxes that made them famous attach to the back of each solar module in an array and convert the DC energy output into AC energy, with a 25-year warranty to give you assurance that your system will withstand decades of use.

Enphase microinverters work with basically any solar panel on the market, and are even integrated into some newer models from major manufacturers. Microinverter technology makes it possible to maximize the output of a solar array even when one or more panels are shaded or defective.

In a traditional situation, a string of solar panels is wired together and the output of the whole string is limited by the current flowing through the least-producing panel. Microinverters provide each panel with the opportunity to produce as much electricity as it’s able.

The apps also include a virtual display of your array that color-codes modules based on how much energy they produced during the defined period. This helps you identify any modules that might not be working properly based on how much energy they produce compared to their counterparts.

The app is also a one-stop shop of communication with your solar installer, Enphase, and your social media networks, allowing you to share production reports via email or social posts, contact your installer for troubleshooting, and even begin a warranty claim for a faulty microinverter.

SolarEdge is a manufacturer of solar string inverters that can be paired with power optimizers attached to each solar module in an array. With the power optimizers installed, SolarEdge’s monitoring applications can track the production of individual panels over time, just like Enphase can.

The mySolarEdge app and web portal offer about the same functionality as Enpahase’s solution. The app can track energy produced, self-consumption, grid exports, and battery charge and discharge. It also includes remote operation of smart devices such as the company’s smart EV charger.

All in all, SolarEdge competes favorably with Enphase, but the additional complication of having module-level power electronics and a central string inverter adds a bit too much complexity.

Additionally, the power optimizers carry standard 25-year warranties, while the standard warranty for SolarEdge inverters comes with a 12-year term, with extensions of as many as 25 years, available at an extra cost.

SMA is a company that knows how to build top-quality solar inverters. Unfortunately, that knowledge doesn’t extend to highly attractive and user-friendly interfaces.

Honestly, their solution, called Sunny Places, is fine if you want to see the total output of a solar system, but it doesn’t wow with the kind of granular data or a polished user interface (UI) of the two previous entries in this list.

To be clear, nobody should disqualify an SMA installer from consideration solely because they prefer a better monitoring system. As we said above, the company’s inverters are top notch. And when SMA gets their act together and produces a better way to track and compare PV system production, you won’t need to buy anything else to make it work.

There are a few nationwide solar installers that offer monitoring software, but these are mostly re-skinned versions of equipment manufacturer offerings. Other nationwide installers offer web portals with day-after data, but no real-time monitoring.

SunPower is a solar services provider that sells its own branded solar panels, inverters, and batteries through a nationwide network of solar installer dealers. They have a reputation for high-quality products and excellent customer service, and offer full 25-year warranties for product quality and power production. Not surprisingly, the suite of hardware is accompanied by branded monitoring portals for the web and mobile devices.

Tesla is known for their groundbreaking electric vehicles, sleek home batteries, and… troubled solar roof project. But what they’re perhaps best known for is impeccable modern design, and their all-in-one Tesla app is a perfect example.

Tesla offers a UI that allows users to view real-time and historical solar production, home energy use, and Powerwall battery charging and discharging. The interface is slick and, to coin a phrase, “It just works.” But that slickness hides the fact that the functionality is fairly basic.

These solutions from companies like Sense, Curb, and Emporia have additional features that allow you to monitor energy usage in a much more granular way than solar-specific monitoring does.

Unlike rooftop hardware solutions that are tied into each solar module in an array, Sense provides add-on monitoring functionality for systems without a current monitoring solution. The Sense energy monitor itself tracks home energy consumption - even for folks without solar panels - by using AI device profiles to show where energy is being used within a home at any given time.

In order to monitor solar production, the Sense monitor must be connected to an additional two current sensors that clamp onto the wires coming from a solar inverter into your home’s main panel. Once installed and turned on, the Sense monitor immediately begins recording power flows into the home from the solar array and out to the appliances.

The Sense monitoring system also records excess power sent to the grid from your solar panels, so that over time you can get an accurate record of renewable energy production, consumption, and grid export.

For folks without a monitoring setup, adding the Sense Solar energy monitor is relatively easy. It provides great information with an easy-to-use interface, and is well worth its $350 regular price. For these reasons, it gets our recommendation.

These individual connections allow for more accurate monitoring of each circuit, but they also result in a much more complex installation process. These solutions can monitor your incoming solar energy and outgoing energy to circuits like the washer and dryer, air conditioner, or EV charging.

All this sounds great, but you might have a tough time buying a Curb monitor. As of this writing, they’re sold out on Amazon and not available through the Curb website, either. Emporia’s gen 2 monitor is available for sale, so if you want to choose this path, find an electrician who can do the work and start your solar monitoring journey!

No matter what solution you choose, solar monitoring has two basic functions: making sure your system is producing solar power and comparing that production over time to what you expected it to be. All other functions described above are nice to have, but not essential.

For installer-specific monitoring, it’s a toss-up between Tesla and SunPower, because we like Tesla’s app and data displays, but SunPower offers both an app and a web portal that do all the essential things right.

The best systems can track the production of individual solar modules within an array and help identify problems before they wind up costing you a lot of money.

Very pleased so far. However, I am in a queue for a solar battery: that might cause an issue, but I`ll cross that bridge when I come to it.

This arrived the next day after I ordered it - I fitted and installed it in approximately 10 minutes. It instantly works, displaying electricity usage, solar PV generation, or the net of the two. `Does exactly what it says on the tin`. Five stars, I couldn`t find a solution online that did this easily without subscriptions or unnecessary complexity. I would happily recommend to anyone!

With a brand new solar PV and battery system, I purchased the Eco Eye monitor to independently check inverter readings, and as an easy to use visual display of grid import/export. With a direct feed to the solar/battery system from the meter box, I fully understood that I could only monitor the grid power (in/out) and the excess PV power flowing back to support the house load (ie PV less battery charging).

Setup was OK, and it all appears to work. However the display figure fluctuates rapidly, widely, and is often a good 100 watts different to both my smart meter and the Modbus grid meter. This is particularly so when the grid current is low or zero, which happens a lot as my inverter is set up to divert excess solar to the battery. The inverter clearly uses a feed-back loop from the Modbus meter, continually adjusting the battery charging to keep the grid current at zero, and I suspect that this generates noise that the Eco Eye picks up but that the Modbus meter and smart meter manage to avoid or integrate out. This was not unexpected, and the monitor route was by far the easiest and cheapest option for displaying solar performance in the house. However it does regrettably mean the unit is effectively unusable in my situation. I have now, finally and with considerable effort, managed to get the inverter data directly to a Raspberry Pi and Node-Red dashboard that I can view on my PC, but not as yet as a free standing, always on display. You win some, you lose some...

Needed something to replace my old Wattson which had given up the ghost and this was the ideal replacement. Have not experienced any issues with it but have two comments. One, it would be good to have it backlit as the display is not easy to see from a distance. Secondly, supporting software needs a revamp. The windows UI is a bit dated and clunky but operates fine. However, as a user of the the most recent Mac OS, I was unable to get the Mac version of the software to install no matter how hard I tried. Other than that vey pleased over all.

The eco eye and associated software is really great for monitoring energy usage, PV output, energy imported and exported. The charts show energy consumption and pv production very clearly and allow me to get a good handle on how to avoid exporting surplus PV. I will be using this to help me size a battery that will allow me to use all pv and also how much to load the battery overnight with cheap electricity.

It`s a good product. I had to replace a monitor installed with the Solar PV system, as the data collection function was being discontinued, and the Eco-eye more than replaces it. It was easy to set up and seems (so far) completely trouble-free. My only disappointment is that the software (a) doesn`t work under Linux, and (b) doesn`t seem to be able to dump the history data from the card via the USB connection -- otherwise fine.

We have found the EcoEye monitor to be an excellent product. It was straightforward for an amateur to install and it is easy to use. The fact that it is wireless means I do not have to go to the solar inverter to check on output. Switching between the different views - PV, consumption, PV minus consumption - is easy and useful. I would certainly recommend it to others.

It was fairly easy to set up once I had worked out which of our old cables was which. The display is really clear and I`m sure it has saved us money as we are much more careful about when we turn appliances on to make best use of the solar panels. I have never managed to make the memory card work - I had imagined that I would have some great spreadsheets showing our use over time, different times of day, solar vs grid, etc. But I don`t have any of that. The spreadsheet I managed to get out was fairly meaningless and the instructions didn`t really help. I should have asked for help from Eco-eye but never quite got round to it.

I purchased this product a few weeks ago, and although my PV meter is a long way from my supply meter, Eco Eye were more that happy to extend the cable for the CT clamp to 10 metres free of charge.

Setup was really simple and after only a week, I was getting excellent information on my electricity usage. I have quickly discovered that battery storage is not viable for me (I have had companies in giving quotes), so will be increasing the size of my solar array instead.

I found this product very easy to set up and within minutes it was providing me with the net production/consumption figure I wanted to see. I also have a second display in my office connected to my home-grown home automation system via a cable.

Thanks to the data being fed from the eco-eye, my home system is now able to divert excess power to electric radiators dynamically. The system monitors the house power situation along with things like room temperatures and makes decisions about switching on and off individual radiators. If the kettle is turned on, it switches off the heating immediately but if a cloud passes over it waits a minute before reacting. I am very pleased with the eco-eye products. They are doing exactly what I wanted; providing easy to read displays for me along with real time data to maximise my solar power and reduce my central heating costs.

I bought a eco-eye SmartPV moniota along with an additional display so I could see both generation and consumption at the same time. I was slightly puzzled when they both said exactly the same thing. But a quick call to the eco eye Tech team quickly sorted that out. I`ve got a Solar boost diverter (to heat hot water when I`m generating more electricity than I`m consuming) and it had kicked in. Which explained why both reading were the same.

I have an unusual situation where the PV panel feed enters the house on a separate consumer unit and 30m away from the mains power entry point. Eco-Eye were very helpful and advised that although this situation had not been tested, they felt sure it would work. In practice is works perfectly and the large transmission range of the unit means that I can have the display in any position in a very long house. With power readings recorded every 4 seconds, I now have the potential to do any analysis I want.

I needed a device that would give me information that I could download into a graphical format for future use. Especially, I needed some idea of my house base-load over a prolonged period, in order to help me make decisions on future home electrical installs. I also needed to see this data in relation to PV production, and PV export.

Downloads aside, I do find the the monitor very useful. It`s in the kitchen and at a glance I can see if my PV production is good enough to put on a load or two of washing, or baking and the like. I`m very pleased, it`s an excellent product.

Great product, but it isn"t quite as accurate as it could be. The unit gives an accurate reading when the solar generation is low, say 200w, but if this increases to anything above 500w, the device suggests that the house consumption is in excess of 1kw/hr despite few appliances running.

I downloaded the Manual, had a good read, and then installed the Trax software on Windows 10 Pro. And when I connected the Display to my PC with the USB cable, there it all was - Everything I wanted to see about instantaneous usage.

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.
