Best Solar Companies in St. Petersburg, FL

A typical solar panel installation costs anywhere from $7,544 to $21,553 in Florida. Prices in St. Petersburg are comparable, ranging from $7,401 to $21,145.

This doesn’t include an energy storage battery, which sometimes costs as much as the panels: $7,000 to $18,000. A battery lets you store excess energy generated during the day and use it when your panels aren’t producing, like at night or during outages. It’s worth considering if your area gets frequent blackouts or if you don’t opt into St. Petersburg’s net metering program.

System size is the other major solar cost factor. The average St. Petersburg household needs a system with a capacity of 10.75 kW (kilowatt) to fully offset their electricity costs. Depending on how much energy you and your family use, you might need a smaller or larger one.

How can I pay for solar panels?

Getting solar panels is like buying a car. Most people pay cash, finance or lease. The newly funded Solar for All program aims to make solar panels more accessible to low-income households, especially those in historically underserved communities, in the near future.

• Solar loans work like any other type of loan. They have relatively low fixed interest rates. Once you pay it off, you own your system outright.
• Solar leases are a good option if you have limited savings and don’t want to take on debt. A potential downside to leasing is that you won’t be eligible for the federal solar tax credit.

Solar panels are generally worth it in Florida if you like the idea of lowering your monthly utility bills. On average, St. Petersburg homeowners with solar panels can avoid $108,915 in total utility costs over 25 years.

The main drawback is the high upfront cost of purchasing and installing the panels and equipment. Assuming an upfront purchase, it takes about 7.85 years to break even (when your savings with solar panels make up for the cost).

Considering Florida averages 3.5 to 4.5 peak sun hours each day, switching to solar is worth considering. We suggest using NREL’s PVWatts Calculator to estimate how much electricity a solar panel can produce over a year on your house. Project Sunroof is a reliable online solar savings estimator.

Potential roof problems

As a rule of thumb, if your roof is more than 10 years old, consider fixing it before going solar. Installing solar panels on an old roof might mean you have to remove the panels, replace your roof and then reinstall the panels again. This is an expensive and frustrating process.

In our experience, the best solar companies in Florida have a few things in common: lots of experience, reliable equipment and transparent contracts. Here are some hiring tips.

• Check certifications: Solar companies must apply for panel certification through Florida Solar Energy Center’s Photovoltaic Certification Portal, and you can confirm registrations through the FSEC’s Registered PV Modules page.

  We also recommend choosing an installer certified through the North American Board of Certified Energy Practitioners (NABCEP).

• Read reviews: Avoid companies with recurring complaints about misleading sales tactics, equipment failures, billing issues and lack of communication.
• Compare costs: Get multiple solar quotes from different companies to make sure you’re getting the best deal.
• Ask questions: Do you need a solar storage battery, electric vehicle (EV) charger or critter guards? How does this affect overall pricing? What if your system needs maintenance? If you don’t understand something about the payment terms, warranty or ongoing services, ask for clarification.

According to the Florida attorney general, common solar scams are related to pressuring salespeople, misleading contract terms and over-promised savings.

The 30% federal solar investment tax credit (ITC) is still the best incentive for most homeowners. It reduces your federal tax liability by 30% of how much it costs to install solar panels. You can combine the ITC with local solar incentives in Florida to maximize savings.

For instance, solar equipment is exempt from sales and property taxes. A solar property tax exemption means that — for tax purposes — the addition of a solar energy system won't result in an increase in your property's assessed value. Essentially, your property tax bill won't go up because your solar panels increase your home’s market value.

Federal solar tax credit expires at the end of 2025

The ITC is now set to expire at the end of the year, much earlier than previously scheduled. The credit was expected to drop gradually, then fully expire in 2035 — but those future step-downs have been eliminated under the “One Big Beautiful Bill,” signed in July of 2025. This means you have until Dec. 31, 2025, to install and pay for a system to qualify for the 30% credit.
