Frequently Asked Questions (FAQs)
1. How big of a solar system do I need to go off-grid?
Most data suggests that a typical American home (2,000 square feet home) consumes approximately 11,000 kilowatt-hours annually. So, when we divide our total consumption by the expected output of one solar panel, we see that roughly thirteen solar panels of this size would be enough to power a home of that size.
2. How many batteries do I need for off-grid solar system?
If you want to keep the power on when the grid is down, you'll usually just need one solar battery. If you want to go off-grid completely, you'll need far more storage capacity, more along the lines of 8-12 batteries.
3. How much does 20kw off-grid solar cost?
As of January 2022, the average cost of solar in the U.S. is $2.77 per watt – that comes out to about $55,400 for a 20 kW system. That means that the total cost for a 20 kW solar system would be $40,996 after the federal solar tax credit discount (not factoring in any additional state rebates or incentives).
