Solar panels are graded by how much power they use. You need a sunny roof to benefit from solar panels but yours may be sunnier than you think. A peak sun hour is typically defined as an hour of sunlight that offers 1 000 watts of photovoltaic power per square meter. What the sun will provide.

Peak sunlight hours describe the intensity of sunlight in a specific area. The panels you would use in a residential setting typically range from 275 to 350 watts per panel. Take your system size and divide by the panel wattage to figure out how many solar panels you need in your system. Considering 6 peak sun hours per day and 300 watt panels you need 16 to produce 700 kwh each month.

How many solar panels do i need to power my house. The typical homeowner will need 28 34 solar panels to cover 100 of their energy usage dependent on location and roof size. Let s say we want to use astronergy 335w panels. Assuming we get 5 hours of direct sunlight we know a 100 watt solar panel will produce 30 amp hours per day.
