The amount of power that a rooftop solar system can generate depends on several factors:Panel Wattage: To be clear and as it is now, the existing average watt rating of solar panels is approximately about 250-400W. . Sunlight Exposure: Thus, the studies presented reveal that the electric production of the solar system is determined by the location of the home, the angle and orientation of the roof, as well as climate conditions. .
