5 solar panels with the best warranty
Solar panels don’t have any moving parts and they rarely fail. But when they do, it can be a real pain. Relative to the total cost of your system, one solar panel isn’t that expensive. A budget panel might retail for $200, while a premium one might cost twice as much. But if you have a panel failure on your roof, not only do you have to worry about the cost of replacing the part, but the labor cost of having a technician come to your house, diagnose the problem, climb onto your roof, deinstall the bad panel and install a new one.
