While a 5 kW system will only cost you $15,332 in Marstons Mills, MA, doubling the system size effectively doubles the price, so you'll pay about twice that for a 10 kW system.

If you can't shell out $15,332 in cash to pay for solar, don't sweat it. You can choose to finance your system with a loan instead. Some companies even offer $0-down loans so you can start saving on day one if your loan payments are less than your current electric bills. Just keep in mind that your long-term savings will be lower with a loan due to interest rates.

For homeowners who prefer not to own their system or want to keep capital flexible, solar leases and power purchase agreements (PPAs) often provide immediate savings with no money upfront. They're not offered everywhere, though, so it's worth double checking that providers offer these types of agreements systems in your area.

The numbers we're showing are averages. The price you'll pay for solar depends on many factors unique to you and your home:
