PTC Peak Watts are the REAL-WORLD rated optimum DC power created under PVUSA Examination Problems for sunlight and temperature.
A higher % is better, yet make sure to balance that with the expense of the panel. The majority of conventional photovoltaic panels have performance from 14% to 20%. Some greater performance panels can be dual the rate of ordinary performance panels.
