You'll probably pay even less than what we show here. It doesn't include the federal ITC or South Milwaukee, 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 $15,224 in South Milwaukee, 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 $15,224 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.
