Determining how many solar panels to power a house is a personalized process, influenced by several factors including your household''s energy use, local climate, and the efficiency and wattage of the solar panels you choose. As we''ve learned, an average U.S. home requires between 17 to 25 solar panels to meet its energy needs.
Next, you''ll need to know how much electricity one solar panel can produce. Solar panels come in different sizes and power outputs, typically ranging from 300 to 450 watts per panel. The power output (wattage) of the panels is rated based on how much power they can generate per hour under optimal conditions.
A 400-watt panel can generate roughly 1.6–2.5 kWh of energy per day, depending on local sunlight. To cover the average U.S. household’s 900 kWh/month consumption, you typically need 12–18 panels. Output depends on sun hours, roof direction, panel technology, shading, temperature and age.
Before sizing a solar array, it helps to know a few key terms: Watt (W): measures power. A solar panel rated at 300 W can deliver that amount under optimal sunlight. Kilowatt-hour (kWh): a unit of energy equal to 1,000 watts for one hour. For instance, a 300 W panel producing peak power for four hours generates 1.2 kWh that day.
