In a conventional solar panel, if a single cell is covered by a leaf or dirt, the panel could see a 33 percent reduction in power output. A SunPower X-Series panel might only see a 6 percent reduction in output. How Much Energy Does a Solar Panel Produce? So how much power does a SunPower panel produce?
