Most residential solar panels have wattage ratings ranging from 250 to 400 watts, with the most efficient models being between 370 and 445 watts1. Depending on the energy demand and solar exposure, it typically takes about 17 (400-watt) panels to power a home, which can vary from 13 to 19 panels2. Thus, the total wattage installed can vary significantly based on the number of panels and their individual ratings. [pdf]
