Trina Solar

I installed Trina solar panels on my roof , they failed to various degrees after 9 years . The worst part was dealing with the company for a warranty replacement , they dragged the process out for many months , ignoring emails for weeks on end . When I finally did receive a percentage of the panels , bcause they only guarantee a percentage to last , the panels were out of date and commercially unavailable , which meant I couldn't purchase more to make a full array . They would not replace them with new panels , but did offer to sell me 4 more for about $1000 US . I gave up , after not having panels for so long and loosing money , I just bought a whole new array of quality panels for less than the cost of the extra 4 they wanted to sell me . Be careful with this brand
