You'll probably pay even less than what we show here. It doesn't include the federal ITC or Fond du Lac County, WI state incentives, which will lower this price by at least a few thousand dollars.

Your solar panel cost depends on your system's size

It may seem obvious but larger solar panel systems cost more money. We use cost per watt ($/W) so you can easily compare quotes, controlling for slight variations in system size.

While a 5 kW system will only cost you $15,614 in Fond du Lac County, WI, doubling the system size effectively doubles the price, so you'll pay about twice that for a 10 kW system. The higher the price tag, though, the more you'll get back as a credit towards your federal tax bill.

If you can't shell out $15,614 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.

Take advantage of federal and local solar incentives
