Consumer Reviews of Canadian Solar Solar panels
We had one panel (of 60) which dropped a third of its power after a month or so of operation. At first, it would work ok until it heated up at around 10 AM. But then it always was at 2/3 power. Our installer replaced that panel and all have been working well since. We have had no other issues.... read more
I can't say that the system has ever reached the 5 KW that it is supposed to.

Expert Review
Canadian Solar Panels Summary
The Canadian Dymond series of panels are a good quality solar panel with a top efficiency on their 300 watt monocrystalline system of 18.33%. The temperature coefficient, a measure of the amount power output falls as temperature rises isn’t particularly good at -0.39%.
The key reason that we rate Canadian in our top 5 as a solar panel brand is not the performance of the solar panels per se it is the value they offer, their stable financial position and their reputation for manufacturing quality control.

1. My Canadian Solar panels are producing a little more than I had expected. This means that maybe, I could have gotten by with one or two fewer panels, but since I am purchasing an electric car, the extra production will ensure that I will be covered for my future growth in power requirements.
2. Although I am pleased with my installation, this review should only be about the panels themselves.
3. I live in the high desert north of Los Angeles and we have few clouds but very high heat. I have checked my power generation during heat waves and the panels did not seem to be affected by days of over 106⁰ F temperatures.
4. I don’t know if Canadian Solar makes polycrystalline solar panels but my Canadian Solar panels are the higher producing monocrystalline solar panels which cost a little more but are more efficient.
5. I have not had my panels for an entire year yet, so I will have to see how well they produce during the shorter (less sunlight) days of winter.
6. Do not confuse your installers or your installation with the panel manufacturer. The panel manufacturer does not control how the panels are installed, which direction they face, what angle they face, or how many sunny days your town has per year. These are factors that affect your energy production but are not a reflection of the solar panel’s quality, generation, or efficiency.... read more

Exceeds expectation on partly cloudy days- seems to try to make electricity with any amount of sunlight but will produce nothing under heavily overcast days. Clearing snow is easy with a snobrum. I usually just clear part of lower panels and they do the rest usually within hours. If upper panels do not clear, I start clearing them as well the next day ( they are harder to reach) and clearing even a small portion of a panel will generate enough heat to clear the rest in 1-2 days. I was gone for 3 weeks during an unusually snowy January when the panels were not cleared of snow at all. Production as anticipated was way down.... read more

The key to a good panel is how well they perform. Too much of a variance and your system needs to compensate for the different outputs. Well, my system does this, but it is amazing just how well balanced all these panels are from one to the next.
