How Many Solar Panels To Power An Average House

Garrison stated that the typical home is approximately 1 500 square feet with electrical costs of about 100 per month.

How many solar panels to power an average house.

So how many solar panels can power an average house for a general idea. Assuming a given solar panel produces 250 watts of power you d need 28 to 34 of them to meet your annual electricity requirements. An average homeowner needs 28 to 34 solar panels to fully offset their electricity bill with solar. You will need a roof space of about 340 sq ft for a 5kw system.

Such a house generally needs about 16 panels to completely cover electrical power needs. 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. A 10kw solar system which consists of 40 panels can produce an average of 14 000 kwh per year. A 5kw solar system which consists of 20 panels can produce an average of 7 000 kwh per year.

To calculate the number of solar panels divide the 7 82 kilowatt of solar panels by individual solar panels wattage which is 330 watt in our case 7 800 watt 330 watt 23 63. That means a single solar panel could collect about 1280 watts or 1 28 kwh per day. But do you consider your home average. In the united states the average home consumes about 10 400 kilowatt hours khw of electricity each year.

If you are looking to heat water for the average family of four two solar thermal panels would be needed garrison explained. You will need a roof space of about 680 sq ft for a 10kw system. If you multiply that by 30 you get 38 4 kwh per month and that s just one solar panel. The number of panels you need for your house depends on factors like location and panel performance.
