Factors that Affect Solar Panel Costs in St. Petersburg
The cost of installing a solar system in St. Petersburg can vary by more than $10,000 from home to home. Your actual cost is dependent on several factors. The largest one is your system size, and other factors include the equipment you choose, financing options and the solar installer you choose.
Solar Equipment
The size of the solar energy system you need for your household, which is measured in kilowatts, is the most important cost factor to consider. For every additional kilowatt you need, you can expect your total to increase by nearly $3,210. There are a lot of different solar panel brands and the one you choose also affects the cost. Typically, the brands that have better efficiency tend to also cost more. Additionally, the type of equipment you’re looking to install can affect your total cost. If you just need panels, your system will be far less expensive than if you also need solar batteries or an electric vehicle charger.
Solar Financing Terms
If paying for solar panels out of pocket is too expensive, solar loans are an affordable choice because they lower your upfront costs and allow you to pay for your system over a term of, on average, between five and seven years.When considering your overall cost, you should also calculate the interest you’ll pay if you go with a solar loan. Also, paying more upfront can reduce the total interest paid over time.
Solar Panel Installation Company
The solar installer you go with to handle your switch to renewable energy can play a role in your total costs. There are about 3 solar panel companies operating throughout St. Petersburg, and each can charge different amounts for labor and equipment.Larger national companies usually have lower costs, but some local companies compete with them by offering sales and discounts. While the smaller companies might not have specific equipment options like Tesla Powerwall batteries or additional services like electric car charger installation, they might be cheaper overall.

How to Save on Solar Panels
The company that does your solar system installation will affect the warranties and brands available to you, and it will also have an impact on your total cost. Because selecting a company can be difficult, we have some tips to help you, such as:
- Installation Process: One of the most important things to understand when adopting solar energy is the installation process itself. Be sure to clarify any details you should know with your solar company, such as what permits you should acquire and how long the project will take.
- Solar Panel Brands: Not all solar installers have the same brands of solar panels, so the brand and type of panel you want can play a significant role in the company you choose.
- Contract: Before signing a contract with a solar company, make sure you look it over fully so you understand the terms. Also, ask questions if you aren’t sure about some of the terms, such as what the warranty covers and if there are any guarantees about energy production.
- Warranty: Warranties that provide coverage for defective panels and repairs over a long period of time such as 25 years are the gold standard in the business, and offering that kind of warranty is one indication of a good company.

EcoWatch's St. Petersburg, FL Solar Cost FAQs
What is the average cost of installing solar panels in St. Petersburg?
This is a tough question to answer exactly, because the cost depends on many factors. Broadly speaking, it costs about $16,050 for a 5-kW system and $32,100 for a 10-kW system after the ITC is applied. It will be more expensive if you want additional solar equipment or higher quality panels, or if you have higher-than-average energy usage. Conversely, you can spend less if you want a smaller solar panel system or cheaper solar panels.
Are solar panels free in St. Petersburg?
You can’t get solar panels for free in St. Petersburg. However, you may still be able to install them on a lower budget. You can lease solar panels for a low upfront cost or, if you’d prefer to own your solar panels, you can finance them with a solar loan.
Does St. Petersburg have a net metering program?
Each state has some kind of net metering programs except Tennessee, South Dakota and Alabama currently. Some states let you sell power back to the grid, but others just offer you credit toward your future utility bills.
How long do solar panels last in St. Petersburg?
Even though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they stop working completely at that time. What this means is their energy production will have decreased significantly after that point. You can decide to replace them once you've had them for that long or you can keep using them at a lower efficiency.
