You'll probably pay even less than what we show here. It doesn't include the federal ITC or Saint Petersburg, FL 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 $10,994 in Saint Petersburg, FL, 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 $10,994 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.

Solar is a major purchase, but you can get the price tag to come down a bit by being an educated shopper. Taking advantage of incentives and rebates and shopping around for quotes can bring down your cost of solar in Saint Petersburg, FL.

Take advantage of federal and local solar incentives

As long as your federal tax bill is high enough, you can take advantage of the federal tax credit in Saint Petersburg, FL. This incentive allows you to apply 30% of your solar installation and equipment costs toward your federal tax bill. If the amount exceeds your tax bill, you can roll over the remaining credit to the following year. Many states also offer great local incentives and rebates.
