We had these panels on the roof for 6 months now, and are very happy with their performance. No problems at all.
I am very happy with the prices. I shopped around it and they had the best deal.
I live in a very wooded area, and even though I do get a lot of sun, it was a concern that that panels wouldn't perform well. To my surprise, I get excellent energy output! I am very impressed with these panels’ efficiency.
The delivery was fast. The product as described.
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.
Excellent product for affordable price
