As of December 2023, the average solar panel system costs $2.54/W including installation in Marathon, FL. For a 5 kW installation, this comes out to about $12,715 before incentives, though prices range from $10,808 to $14,622. After the federal tax credit, the average price drops by 30%.

You'll probably pay even less than what we show here. It doesn't include the federal ITC or Marathon, 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 $12,715 in Marathon, 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 $12,715 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 Marathon, FL.

Take advantage of federal and local solar incentives
