Re: Recommended solar panel brand
Years ago, when manufacturing techniques were highly variable, different manufacturers had a big impact on panel reliability. These days, the solar cell is the main differentiator, and mostly based on improved efficiency. If you’re satisfied with size vs output, Trina is a fine manufacturer.toggle quoted messageShow quoted text
We used SunPower (a premium brand) and Trina (less expensive, lower efficiency cells), but had better reliability from the Trina panels. Our SunPower was down to 55% of rated output after 4 years. They also would not honor warranty, as it wasn’t a home installation made by a professional installer. They refused to warranty on a boat. The replacement Trina’s were at 100%, 5 years later. Given the choices today, if the output and size of the Trina panels met my requirements, I’d happily go with them.
