How Many Solar Panels To Power An Average House

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

How many solar panels to power an average house.

But do you consider your home average. 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. So how many solar panels can power an average house for a general idea. In the united states the average home consumes about 10 400 kilowatt hours khw of electricity each year.

Divide average monthly power consumption by average monthly power generation to get kilowatt of solar panels 900 kwh 115 kwh 7 82 kw of solar panels. A 10kw solar system which consists of 40 panels can produce an average of 14 000 kwh per year. If you multiply that by 30 you get 38 4 kwh per month and that s just one solar panel. 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.

A 5kw solar system which consists of 20 panels can produce an average of 7 000 kwh per year. If you are looking to heat water for the average family of four two solar thermal panels would be needed garrison explained. Such a house generally needs about 16 panels to completely cover electrical power needs. An average homeowner needs 28 to 34 solar panels to fully offset their electricity bill with solar.

Garrison stated that the typical home is approximately 1 500 square feet with electrical costs of about 100 per month. That means a single solar panel could collect about 1280 watts or 1 28 kwh per day. 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. The number of panels you need for your house depends on factors like location and panel performance.
