How Many Solar Panels To Power The Average House

A 10kw solar system which consists of 40 panels can produce an average of 14 000 kwh per year.

How many solar panels to power the 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. So how many solar panels can power an average house for a general idea. But do you consider your home average. Most places in the united states collect only about four hours worth of useable sunlight.

Depending on where you live the average 3 000 sqft house will need between 17 and 26 premium solar panels to supply 100 of its electricity needs. You will need a roof space of about 680 sq ft for a 10kw system. In the example above you would need 24 solar panels to account for 80 of your average consumption 29 6 kwh daily usage divided by 1 24 kwh per panel. Likewise if you wanted to account for 100 of your daily kwh consumption you would need 30 solar panels 37 kwh daily usage divided by 1 24 kwh per panel.

An average homeowner needs 28 to 34 solar panels to fully offset their electricity bill with solar. But as you can see from the data above how much electricity your house uses depends on everything from your local climate to how many televisions you have. A home that consumes 1 000 kwh per month will normally need between 20 and 30 solar panels. 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.

The exact number changes depending on the specifications of the chosen panel model as well as the sunshine available at the project site. Garrison stated that the typical home is approximately 1 500 square feet with electrical costs of about 100 per month. The number of panels you need for your house depends on factors like location and panel performance. If you multiply that by 30 you get 38 4 kwh per month and that s just one solar panel.

If you are looking to heat water for the average family of four two solar thermal panels would be needed garrison explained. In the united states the average home consumes about 10 400 kilowatt hours khw of electricity each year. That means a single solar panel could collect about 1280 watts or 1 28 kwh per day. Keep in mind that the amount of power your solar system can produce depends on how much sunlight your roof receives and your location.

Such a house generally needs about 16 panels to completely cover electrical power needs.
