Installed these panels across our hotels. Guests love the green energy approach
Needed 720 panels for our logistics hub. No regrets—low maintenance, high efficiency
The installation was finished two days ago. so far so good. Good levels even on bad days. thx for your advice.
These panels power our irrigation system efficiently. Great investment
As a commercial solar installer, we've tried many brands but these 610W panels give our clients the fastest payback period. The higher wattage means fewer racking systems and lower labor costs. The bifacial gain is real - especially on our white-roof installations.
Ordered 720 panels for our production plant—massive savings on electricity bills
We’ve built a great system with those!
Pleasure doing business with you. The order arrived on time and the panels are all fine.
We expanded our business with these panels. Energy savings are noticeable, and they work flawlessly.
The panels work well and produce a decent amount of power, but I expected slightly better performance in low-light conditions. Installation was smooth, and the quality seems excellent. Overall, a solid choice, but I wish they had slightly higher output in the winter months
Durable and efficient. We’ve been using them in our factory for months with no issues

We ran a number of cost analysis scenarios before deciding that these Canadian Solar solar panels were the best option for our 20 kW off-grid project in Oregon. The store processed our order extremely fast and we picked up the panels a few days later

Very nice panels. the Canadian Solar 455 performs to spec. These are the first panels I have ever owned that actually output the stated wattage. A1 has great sales and service, are very helpful and deliver fast.
We’re very grateful to a1solarstore for making a good offer on those panels. We've managed to build a 20 kW system in Oregon with these ones and so far they prove to be very effective. Thank you. James.

Thanks to a1solar for excellent service and all the advice along the way.
Canadian solar panels are indeed great: well-made and powerful. The installation took quite a bit of time but now that it’s over I can see that going solar was a good decision on our part.

I am happy with these paneld. I mean...tier 1 modules for this price?!
Also i didn't have to buy a ton as in other stores
Thanks A1 Solar!
I liked the design of those things. they look cool on the roof, thye blend well. The gain from the rear side is real, my installer did a great job increasing it. So yeah, i would that panels are worth the money
Canadian Solar is a good brand. My friend had this exact panel and it did a lot of good for him. i consider something smaller, but it will probably be cs as well.

one panel in the pallet had cracks on it, but the store helped to replace it asap.
the PV modules work and that's fine. waiting for the return on my investment.
Certainly a good investment in the long run. Here in Arizona each panel gives me about 500W of power or so, depending on the day. Loads of power, I don't actually feel like I need the grid anymore.

Needed 720 panels for our logistics hub. No regrets—low maintenance, high efficiency
durable panels, comply with specifications, like the all black design
We ran a number of cost analysis scenarios before deciding that these Canadian Solar solar panels were the best option for our 20 kW off-grid project in Oregon. The store processed our order extremely fast and we picked up the panels a few days later
The panels are currently functioning properly; I have an 8 KW system with 5 Kw of feed-in power. I have panels on three sides, East, North, and West. It's a good system, and I'm satisfied with it so far. wishing it will continue to function flawlessly for many years. I still think the system will maintain its lead, even with a chilly winter and impending price increases.

Hi
We’ve ordered a batch of these panels for our shop in Oregon. Even though it can get pretty cloudy here, the panels are doing fine. This is actually why I chose CS, because their panels are known to be good in bad weather. The service was excellent and i’m here just to thank you, peace
great service. please send my gratitude to your engineer
Your engineer is really cool and helpful. Thanks a bunch. Dan
great service. please send my gratitude to your engineer
a good price. i think polycrystalline are still good even though they lose out to mono panels in terms of production. glad that cs is still making them
So i bought this one. Since it’s a polycrystalline panel, it’s significantly cheaper and with a bifacial gain it’s a solid alternative to a simple mono panel in my opinion.

we’ve purchased a number of these panels for our farm in Louisiana. So far it has been wonderful experience! thank you, we love your prices and attention to details. Dan and Lia
the delivery was on time, the panels are in good shape. glad that the price was this low. buying wholesale is wholesome
Panels are very good, a bit larger than I anticipated. I’ve installed them in my yard, they work from dawn till dusk. The service was fine, delivery guys took their sweet time to arrive, but all is well what ends well.
We are quite happy that we chose an East/West layout for our roof because they produce pretty early in the morning and continue till late into the evening. a great deal longer than our old system. Also want to thank A1 for excellent work
The operational data greatly surpassed our initial assumptions. With the exception of an early inverter repair, the whole system (panels, inverters, and batteries) has been steady and dependable.

A1 is great! They are very helpful, knowledgeable and fast. They take pride in their work, and they package the panels for safe delivery.These panels are absolutely great. They actually produce the rated 455W and more on colder days. I am so glad I bought them on A1's recommendation. Thank A1.
We’ve used these panels for over half a year on our farm in Colorado. They are very strong. I don't feel like the rear side adds a lot but it’s more like my fault though, I should figure a way to make sunlight bounce off the roof, but I haven't been able to get to it yet.
These panels are the most cost-effective option available today. And they're doing it without sacrificing quality.

good price! and even though it’s a polycrystalline panel the output is reasonable. the panel looks as well. I like the fact that CS still keeps polypanels alive, there are kinda cool looking
Powers our data center

canadian solar panels are the best. this model only proves it. Thanks for delivering the pallet on time!
I have had these for two months and so far, I'm very happy. The change in performance on cloudy days is noticeable, but still much better than it is with my neighbor's panels!
not gonna lie, these solar pannels are just average. they do their job, but nothing exceptional. i expected more for the price i paid.
a very good panel! I like the production and it does well even when the sun is barely shining. i took the measurements on sad gloomy day and it was at around 90%. impressive
We’ve used these panels for over half a year on our farm in Colorado. They are very strong. I don't feel like the rear side adds a lot but it’s more like my fault though, I should figure a way to make sunlight bounce off the roof, but I haven't been able to get to it yet.
We’ve set these panels up on our shop in fontana (flat roof setup). Really good performance, seems like the idea will pay off soon. the store is fine, we’ve grabbed the order from their center nearby, easy-peasy.
Although I don't know much about all this solar equipment, these CS panels seem to be performing well and providing the promised results. A1 did a great job processing and delivering my order!
I’ve been really enjoying canadian solar panels in general and this one didn’t disappoint as well. some guys on a forum recommended me this shop and i was pleased with the service so thank you

Each cell in these Canadian Solar panels is completely black, so the panel is uniformly black, which is very cool. I am pleased with the neat appearance and the secure installation by my installer. Our setup is far more aesthetically pleasing than the other solar panels in the area.
We’ve built a great system with those!

Pleasure doing business with you. The order arrived on time and the panels are all fine.
The service is really good, delivery is on time. The panel itself is okay, but i found it to be a bit too big and heavy for the power it provides. at least it’s cheap tho
Installed panels across new residential projects. Homebuyers appreciate it

More value for the money. high quality.They were just as good as or even better than their Chinese rivals, but slightly less expensive. Delivery was also very quick.
came from reddit to your website, was hesitant at first, but made the purchase. All is good here!
Low maintenance, high performance
Got my panels, everything’s in good shape. Very happy with the service and all the advice I got from you. As for the panels, we’ll see how they do!

I highly recommend this panel to anyone looking for a reliable and high-performing solar solution.
Best bang for your buck
These panels are the most cost-effective option available today. And they're doing it without sacrificing quality.
It's barely a week, and the system has been through a snowstorm already. No damage, kept working the whole time. We are very impressed. Canadian Solar, our installer, and A1Solar all did their jobs extremely well.
So far nice store, quality panels
When investing so much time and money, you should use the best materials you can afford. You'll be happy you did. For me CS is as good as it gets
I recently purchased this Canadian Solar panel for my home in Arizona. I must say, I am thoroughly impressed with this panel's performance. It was easy to install and has been consistently delivering high energy output, even on cloudy days. The sleek black design adds a modern touch to my rooftop and the efficiency of the panel has exceeded my expectations. I highly recommend this panel to anyone looking for a reliable and high-performing solar solution.
We’ve set these panels up on our shop in fontana (flat roof setup). Really good performance, seems like the idea will pay off soon. the store is fine, we’ve grabbed the order from their center nearby, easy-peasy.
Very nice panels. the Canadian Solar 455 performs to spec. These are the first panels I have ever owned that actually output the stated wattage. A1 has great sales and service, are very helpful and deliver fast.
I highly recommend the Canadian Solar 395W panel. It's efficient, easy to install and looks great on my roof. Great value for the price! One of the twenty panels arrived with a crack, but A1 replaced it without hassle.
Your engineer is really cool and helpful. Thanks a bunch. Dan
Our installer suggested these panels as the best overall value in terms of cost, output, efficiency, and service life. A1Solar had the best price among all the equipment stores that we checked
Panels are very good, a bit larger than I anticipated. I’ve installed them in my yard, they work from dawn till dusk. The service was fine, delivery guys took their sweet time to arrive, but all is well what ends well.
We’ve used these panels for over half a year on our farm in Colorado. They are very strong. I don't feel like the rear side adds a lot but it’s more like my fault though, I should figure a way to make sunlight bounce off the roof, but I haven't been able to get to it yet.

top notch service. I got great advice from the shop’s engineer. very professional straight-up man. thanks

Certainly a good investment in the long run. Here in Arizona each panel gives me about 500W of power or so, depending on the day. Loads of power, I don't actually feel like I need the grid anymore.
Great investment, huge savings on energy
The panels are currently functioning properly; I have an 8 KW system with 5 Kw of feed-in power. I have panels on three sides, East, North, and West. It's a good system, and I'm satisfied with it so far. wishing it will continue to function flawlessly for many years. I still think the system will maintain its lead, even with a chilly winter and impending price increases.
Outstanding customer service. We appreciate having worked with A1 Solar Team; they were very professional, provided good customer service, were always in touch, delivered the panels on time, and charged a fair price.
Our school switched to solar with panels. Sustainable education
I liked the design of those things. they look cool on the roof, thye blend well. The gain from the rear side is real, my installer did a great job increasing it. So yeah, i would that panels are worth the money
We’ve set these panels up on our shop in fontana (flat roof setup). Really good performance, seems like the idea will pay off soon. the store is fine, we’ve grabbed the order from their center nearby, easy-peasy.
I was actually waiting for the panel to appear in your store to buy it haha. Thank you very much for what you do!

Powers our EV stations perfectly
Although I don't know much about all this solar equipment, these CS panels seem to be performing well and providing the promised results. A1 did a great job processing and delivering my order!
We are quite happy that we chose an East/West layout for our roof because they produce pretty early in the morning and continue till late into the evening. a great deal longer than our old system. Also want to thank A1 for excellent work
More value for the money. high quality.They were just as good as or even better than their Chinese rivals, but slightly less expensive. Delivery was also very quick.
I liked the design of those things. they look cool on the roof, thye blend well. The gain from the rear side is real, my installer did a great job increasing it. So yeah, i would that panels are worth the money
the delivery was on time, the panels are in good shape. glad that the price was this low. buying wholesale is wholesome
I’ve been really enjoying canadian solar panels in general and this one didn’t disappoint as well. some guys on a forum recommended me this shop and i was pleased with the service so thank you
The installation was finished two days ago. so far so good. Good levels even on bad days. thx for your advice.
Got my panels, everything’s in good shape. Very happy with the service and all the advice I got from you. As for the panels, we’ll see how they do!
canadian solar panels are the best. this model only proves it. Thanks for delivering the pallet on time!
a very good panel! I like the production and it does well even when the sun is barely shining. i took the measurements on sad gloomy day and it was at around 90%. impressive
Pleasure doing business with you. The order arrived on time and the panels are all fine.

a good price. i think polycrystalline are still good even though they lose out to mono panels in terms of production. glad that cs is still making them
So i bought this one. Since it’s a polycrystalline panel, it’s significantly cheaper and with a bifacial gain it’s a solid alternative to a simple mono panel in my opinion.
We’ve set these panels up on our shop in fontana (flat roof setup). Really good performance, seems like the idea will pay off soon. the store is fine, we’ve grabbed the order from their center nearby, easy-peasy.
Solid service, very professional staff. polite but very straight up. i can respect that
great service. please send my gratitude to your engineer

Thanks to a1solar for excellent service and all the advice along the way.
Canadian solar panels are indeed great: well-made and powerful. The installation took quite a bit of time but now that it’s over I can see that going solar was a good decision on our part.
great service. please send my gratitude to your engineer
came from reddit to your website, was hesitant at first, but made the purchase. All is good here!
good price! and even though it’s a polycrystalline panel the output is reasonable. the panel looks as well. I like the fact that CS still keeps polypanels alive, there are kinda cool looking

I have had these for two months and so far, I'm very happy. The change in performance on cloudy days is noticeable, but still much better than it is with my neighbor's panels!
Canadian Solar is a good brand. My friend had this exact panel and it did a lot of good for him. i consider something smaller, but it will probably be cs as well.
Your engineer is really cool and helpful. Thanks a bunch. Dan
we’ve purchased a number of these panels for our farm in Louisiana. So far it has been wonderful experience! thank you, we love your prices and attention to details. Dan and Lia
These panels reduced our operational costs significantly. Great quality
The service is really good, delivery is on time. The panel itself is okay, but i found it to be a bit too big and heavy for the power it provides. at least it’s cheap tho
So i bought this one. Since it’s a polycrystalline panel, it’s significantly cheaper and with a bifacial gain it’s a solid alternative to a simple mono panel in my opinion.
We’ve built a great system with those!
Just letting you know that I got the package and everything is good inside. good job!
Hi
We’ve ordered a batch of these panels for our shop in Oregon. Even though it can get pretty cloudy here, the panels are doing fine. This is actually why I chose CS, because their panels are known to be good in bad weather. The service was excellent and i’m here just to thank you, peace
We’re very grateful to a1solarstore for making a good offer on those panels. We've managed to build a 20 kW system in Oregon with these ones and so far they prove to be very effective. Thank you. James.
Certainly a good investment in the long run. Here in Arizona each panel gives me about 500W of power or so, depending on the day. Loads of power, I don't actually feel like I need the grid anymore.
That’s to a1 staff for the recommendation. i found the panels to be to my liking. the service was good and i might be back for more if i find some other places to install solar haha
we purchased these for our cafe in phoenix a while back and i figured that they’ve already paid back half of their cost in i guess 3 years or so? anyway, great product, much recommended.
the service is great, i admit it. Very professional staff, they know what they sell. Delivery was on time which is nice. will be back for more!
Thanks for all helpful advice about panels and especially about the pickup process! Your articles also help a lot, you’re doing god’s work, peace!
We used this particular panel to build a small farm in California. We didn’t have a lot of land so we've chosen bifacial panels. So far they don’t disappoint. No, they don’t disappoint at all. Even on cloudy days they do decently, which I certainly didn’t expect.
We’ve used these panels for over half a year on our farm in Colorado. They are very strong. I don't feel like the rear side adds a lot but it’s more like my fault though, I should figure a way to make sunlight bounce off the roof, but I haven't been able to get to it yet.
warranties are nutz. props to canadian solar, not a lot of brands offer 25 year product protection.
The package from A1 arrived as promised, panels are fine. I’ll test them out but as far as the service goes, everything was top notch!
The installation took a while, but it’s done. So far the panel delivers exactly as promised, i monitor them everyday. we’ll see what the future holds, but so far i have no complaints.
I have had these for two months and so far, I'm very happy. The change in performance on cloudy days is noticeable, but still much better than it is with my neighbor's panels!
As someone who lives in florida i just needed panels that would be able to endure all the different kinds of weather that comes here. i bought these. so far they are just perfect. i love the design, i love the look, i like how clouds barely affect them. when the hurricane comes, i’ll be ready
i dig CS panels in general and it’s a pretty solid module from them. the design is good and it does well in cloudy weather.
Was waiting for that to arrive on the market!
I was a bit discouraged when I discovered that the panels are actually made in China, but maybe I was prejudiced! They are top quality to me, do really well and have really decreased my expenses in these trying times.
Got my panels, everything’s in good shape. Very happy with the service and all the advice I got from you. As for the panels, we’ll see how they do!
The panel looks super beautiful on my roof! Wifey loves them as well. Thanks for solid service!

I’m having a good time with these panels. The output is great and weather is not much of an issue. The installer did a great job getting all the papers and so far i’m really happy with the investment.
I was actually waiting for the panel to appear in your store to buy it haha. Thank you very much for what you do!
Best decision for our business
Delivery was late a lil bit, but no big deal, the staff kept me informed at all times. The panel itself is a solid one. i love the look. the warranties are good. For this money — good deal.
The design might not seem like much, but panels are good. I’ve checked. They barely drop watts even on a dark day.
i liked it. and the service was good too
The delivery was fast and a calculator really did help in planning the system. Pleasure doing business with you guys.
I had a very smooth experience with a1solarstore — their staff helped picking the panels and gave some advice on the installation. I picked this model because it’s cloudy around here. They barely lose power even when it’s raining.
Very content with the service. I ordered this model online, chose the pickup option, then drove to the warehouse, checked the product and drove back. easy
Solar energy makes our winery greener
I purchased these panels half a year ago for my house in the countryside. A system even produces a little more than i expected. had to get a new fridge for the all the surplus
I used the calculator to plan the system for my home. panels arrived in four days. Two were broken, but I contacted the store and they replaced the panels for me, so we are cool. It’s three months, the panels are quite powerful and I'm satisfied.
So impressed with how these panels work on cloudy days! Here in Washington there is frankly not a whole lotta sun, but i still get a nice harvest of it every day. Gotta say, Canadian solar rules
I’m in New York, there really isn’t a lot of sun here, but panels work surprisingly well. Electricity is expensive around here, so i expect these panels to pay off quickly. Thanks!
I like this model. The pallet arrived in 6 days, the installation was very easy. So far everything goes well.
Great service and company. Highly pleased with my purchase.
Thank you and the team we have been in touch with.We have appreciated your help, interest and professional approach – especially.
I would recommend this company to everyone. The guys helped me with my order. Thank you.
Very good custom service ever.
We shopped around and found some questionable retailers who were misrepresenting the origin of their panels. We then saw A1 Solar website.We agreed to accept the quote but upgraded the inverter. We are extremely happy.
From the time I sought a quote from you guys through to selection and paying my deposit the process flowed flawlessly, communication was excellent.
It was a good value for the money for me. The panels are much cheaper than some of the same Tier competitors' modules but much more efficient.
Perfect for our farm, very efficient
I am satisfied with my purchase. The solar panels are efficient, durable, and very easy to clean.
Great communication from the team at A1Solar. Thank you for your customer service and knowledge.
Excellent solar modules at a great price. They are very efficient and very durable.
High quality panels that are durable and efficient. And very competitively priced.
I was looking for a reasonably priced solution for solar. I looked into many options as I did not want to compromise the quality and efficiency. Canadian Solar met my goal exactly. High quality panels for low price. Perfect
Working with A1Solar was a great experience. All the questions I had were answered quickly, they help me set up delivery, and before I knew it, I had my modules. Thank you!
Canadian Solar is one of the best solar manufactures and that is why I choose their panels. So far they are performing very well and cause no problems at all.
Great panels and good overall price. They perform just as estimated by my installer so I am satisfied.
Very reasonably priced panels with great warranty.
Excellent quality panels. Very durable, very efficient and come with unbeatable warranty.
The panels have been working great since the installation. I have no problems whatsoever.
These modules are priced so competitively and still have such an excellent reputation for reliability. I got a good deal!
The installer recommended Canadian Solar to me, mainly because they combine affordable price and high quality. I am glad I listen and got them. Very nice looking panels that seem very durable.
I am very pleased with my purchase. These panels are very durable and look sleek.
I am very impressed with my solar power system. These modules are so efficient.
We use to have a different brand of solar panels that unfortunately stopped working. We decided to go with Canadian Solar this time based on our research and reviews. So far, we have been very happy with how they perform.
This was an easy choice for me. Canadian Solar is known for their highly efficient, durable and quality panels. I found a good deal on this website and saved some money too.
Reliable and eco-friendly power source
These panels not only power efficient but also very cost efficient. I was able to get fewer panels to provide me with energy I needed thus saving a lot.
Solar panels work as expected. We are already seeing saving on our electric bill.
These panels were recommended to me by our installer. He said they are the best for their price, efficiency and warranty. So far, I am pretty happy with them.
These were recommended by the installer we were working with. Quality panels for not a lot of money. So far they've been performing very well.
My friends have Canadian Solar and they convinced me to go with it too. It is too early to know how my panels work but I have heard about Canadian Solar quality and performance before.
These panels exceeded my expectations on cloudy days. It seems they try to make electricity with any amount of sunlight. I am very impressed with their performance.
I really like the color and the texture of the modules. They look very expensive but the truth is, they are very reasonable priced.
I just placed an order for these modules. I have done a lot of research and found that these panels are one of the best on the market. the price is excellent as well.
I found the best deal on these panels on this site. I also had a few questions about inverters and batteries that were promptly answered by their specialists. Delivery took 6 days and all the panels were in perfect condition when they arrived. Thank you for your business.
I trusted my installer that these panels would work for us and I am so glad I did. I am impressed how efficient they are.
The solar system was overproducing in summer, which was a pleasant surprise, so it is really helping me offset my electric bill now. These panels are very efficient!
I am no expert at solar and I felt very confused when I decided to install panels on my roof. I am so grateful for specialists at A1Solar for helping me through the process of choosing and getting my equipment. Thank you guys! I would definitely recommend them to anyone.
I just had these panels installed, and while it is too soon to tell how they perform I can say for sure they look really nice on my roof.
We only considered two brands of solar panels before buying. This one appeared to be much better when compared by price and efficiency.
I do not know a lot about solar panels to compare them but I do know that these panels are working great for me. I had no issues at all after installing these modules.
Price was a big factor for me when I was choosing solar panel. At the same time I wanted a quality product that would last me a very long time. Canadian Solar matched both criteria perfectly. I am very satisfied with my purchase.
I live in Michigan and had my doubts about going solar so I did a lot of research. Now, after having these panels installed for about 6 months I can tell that it is absolutely worth it. The panels are designed in a way that snow is not a problem since it slides off effortlessly. I have been getting plenty of electricity for these past 6 months with no issues at all.
I wanted nice black panels that could blend with my roof. I like that these modules do not have extra frames that stick out. Just a clean look I was searching for.
They look very sleek on my roof. I have not had to do any maintenance or cleaning yet and they still perform excellent. I have had them for a little over 8 months.
I live in California, in the high desert, and it gets very hot here. i was concerned about my power generation during heat waves but, fortunately, the modules do not seem to be affected by high temperatures. I am very pleased with the power production.
I just received the panels but have not installed them yet. Delivery was fast. I will update my review once I know how panels perform.
Thank you for the high-quality product. The panels' energy output is higher than expected.
It has been almost a year since I installed these modules. I love them. Great energy output, no maintenance and no pollution!
I got these panels because of all good reviews I saw on here. Modules look great so far and I am happy with the purchase.
Great looking modules that were delivered to my house in a record time! Thank you
The shipping was fast and the service was great. Now I just need to install the panels.
The whole process of purchasingpanels was very easy. I picked Canadian Solar based on their review and then contacted the store directly for help with accessories. The shipping was fast too. Thank you.
The modules generate great output even in overcast weather. Exceeded all my expectations!
The panels look very durable and sturdy. I did not have them long enough to say how efficient they are but with their excellent warranty I am not worried.
These modules have been performing great since the day I had hem installed. No complaints.
I wanted brand name solar panels but did not want to spend more than I had to. Canadian Solar was a perfect choice for me. Great panels that work and look perfect.
Very efficient, looking sleek, light weight, great warranty. Very happy customer!

I was looking for monocrystalline solar panels that weren’t too pricey, and Canadian Solar was just it.
The panels came just after 6 days after I ordered them. I inspected everything just like they suggest on their website but everything was in perfect condition. Not sure how they work yet, but I do like how they look.
I do not have a lot of space on my roof, so I was worried about even the possibility of having a solar system installed. But Canadian Solar are so compact, that they fit perfectly.

About product
CS3U is part of the 350P Series — one of the most recent made by Canadian Solar. These panels employ cutting-edge technologies to achieve superior efficiency and reliability. This panel takes full advantage of the Passivated Emitter Rear Contact (PERC) technology that allows it to capture up to 12% more energy. All thanks to a reflective layer on the back. This design maximizes the number of photons absorbed by solar cells.
Another advantage is the half-cut cell technology. CS3U has solar cells half the size of those installed in conventional panels. The main benefits are decreased power loss, improved longevity and better low-light performance. Not surprisingly, the efficiency of this module is quite high – 17.64%. Canadian Solar paid as much attention to durability as they did to performance. CS3U is guaranteed to retain at least 84.8% of output after 25 years. Product warranty for this panel lasts 10 years.
- 350 W power output
- 144 half-cut PERC cells
- 17.64% efficiency
- 1500 V DC maximum system voltage
- T4 series or UTX or MC4 series connectors
- 10-year product and 25-year performance warranties
Higher efficiency of up to 17.64%
The highest power output is guaranteed by Canadian Solar CS3U with an efficiency of up to 17.64%. Such outstanding performance is the product of PERC technology and an effective antireflective coating. This is notably above average, which will translate into significant additional savings over the course of operation.
Keeping the cool in high temperatures
Even under extreme heat, CS3U maintains high efficiency. You may take advantage of the sunniest hours because it loses just -0.39% of efficiency for every 1.8°F over 77°F.
Quality and reliability
CS3U is subject to rigorous quality and reliability testing as well as many quality checks throughout the production process. The level of automation in the manufacturing facilities virtually eliminates human error. To guarantee that you receive the finest, REC is committed to quality, safety and dependability.
