How Many Solar Panels To Power A House Off Grid

Keep in mind that the amount of power your solar system can produce depends on how much sunlight your roof receives and your location.

How many solar panels to power a house off grid.

We chose to use 2 150 watt solar panels to power our system. You will need a roof space of about 680 sq ft for a 10kw system. Using the 2400 daily watt hour figure from the above example you would divide the 2400 by 375 and need 6 4 panels. A home that consumes 1 000 kwh per month will normally need between 20 and 30 solar panels.

Now of course this will depend on the wattage of your panels but you should be getting a better idea of what you need to power your setup. Always round this off to the higher number. If you were using 200 watt panels you would need only three panels and four 300 amp batteries.

For this system you would need seven 75 watt solar panels and four 300 amp hour batteries. For the 9600 watt system i need sixteen 100 watt panels and four 200 ah batteries. The two panels are enough to charge our battery generator system completely in about 8 hours of decent sunlight. The exact number changes depending on the specifications of the chosen panel model as well as the sunshine available at the project site.
