The goal for any solar project should be 100% electricity offset and maximum savings — not necessarily to cram as many panels on a roof as possible. So, the number of panels you need to power a house varies based on three main factors: In this article, we’ll show you how to manually calculate how many panels you’ll need to power your home.
A residential solar panel typically produces between 250 and 400 watts per hour, depending on the panel’s size and sunlight conditions. Panels for home systems usually have 60 or 72 small square sections called cells that generate and carry electrical currents.
Energy usage is measured in kilowatt-hours (kWh), or the number of kilowatts an appliance needs for one hour. A residential solar panel typically produces between 250 and 400 watts per hour, depending on the panel’s size and sunlight 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.
