How many solar panels to power average house.

A 10kw solar system which consists of 40 panels can produce an average of 14 000 kwh per year. Such a house generally needs about 16 panels to completely cover electrical power needs. You will need a roof space of about 680 sq ft for a 10kw system. Unfortunately there is no average house with appliances all being different in energy consumption patterns there is no straight answer to that question for every household.

If you multiply that by 30 you get 38 4 kwh per month and that s just one solar panel. That means a single solar panel could collect about 1280 watts or 1 28 kwh per day. Most places in the united states collect only about four hours worth of useable sunlight. If you are looking to heat water for the average family of four two solar thermal panels would be needed garrison explained.

So how many solar panels can power an average house for a general idea. Keep in mind that the amount of power your solar system can produce depends on how much sunlight your roof receives and your location. In the united states the average home consumes about 10 400 kilowatt hours khw of electricity each year. Assuming a homeowner used the national average of 911 kwh per month they would need about 24 solar panels to supply their house with electricity.

Assuming a given solar panel produces 250 watts of power you d need 28 to 34 of them to meet your annual electricity requirements.
