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.

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. ~~~⛵️~~~Matt
