The best wattage for solar panels typically ranges from 250 to 400 watts for residential use. Higher wattage panels can produce more energy, which means you will need fewer panels to meet your energy needs2. Therefore, choosing panels within this wattage range is generally optimal for most solar installations. [pdf]
