We put a lot of effort into ensuring our systems will operate trouble-free in New England winters for 20+ years, which is no small feat!  Exceptional manufacturers help make this a reality.

We recently learned that one of the manufacturers we use for solar electric panels, Canadian Solar, received some of the highest rankings in PV USA (PTC) rankings.

These rankings, required by the State of California, exhaustively test module performance in laboratory settings and are required for a module to be eligible for California’s solar financial incentives.

Five of Canadian Solar’s solar module series, the CS6P- 220P, 225P, 230P, CS5P-240M and CS5A-180M obtained rankings that were near the top of all of those tested.

You can read Canadian Solar’s official statement, or see the full listing of PTC rankings and requirements.

Here are some pictures of recent installations that use Canadian Solar panels:
