How Much Do Solar Panels Cost in Princeton?
An 11.8 kW solar system, sized to cover the electricity needs of a typical Princeton home, has an estimated gross cost of $26,550 in early 2026. This price reflects the full installation before any savings are realized.
- Solar-Only System: $26,550
- Solar + Battery Option: For homeowners seeking backup power during outages, adding a battery costs an additional $15,000, bringing the total to around $41,550. While this extends the financial payback period to about 14.5 years, it provides invaluable peace of mind during hurricane season.
Incentives & Tax Credits
Key Florida Solar Incentives for 2026
Even with the expiration of the main federal tax credit for new 2026 systems, Florida provides crucial financial support for homeowners going solar:
- No Sales Tax on Solar Equipment: You will not pay Florida's 6% sales tax on your solar panels, inverters, or racking. This provides an immediate discount on the total system cost.
- 100% Property Tax Exemption: Installing solar panels adds value to your home, but thanks to a state exemption, it will not increase your property tax bill. This ensures you keep all the financial benefits of your investment.
These two state-level policies are fundamental to making solar a financially sound choice for Princeton residents.

Understanding Net Metering with FPL
Princeton homeowners benefit from Florida Power & Light's retail-rate net metering program. It works like this: during the day, your solar panels often produce more power than your home needs. This excess energy flows to the grid, and FPL credits your account at the full retail value for every kWh you provide. At night, you draw power from the grid, and your accumulated credits are used to offset the cost. This 1-for-1 exchange is the most favorable arrangement for solar owners and is a primary driver of the fast payback period.
Projected Savings
Your Potential Solar Savings in Princeton
A solar installation is an investment that pays you back over time. For a typical 11.8 kW system, homeowners can anticipate first-year savings of approximately $2,256, effectively eliminating the average monthly FPL bill. This results in a quick financial payback period of just 10.1 years.
One of the most significant long-term benefits is protection from rising utility costs. By generating your own power, you insulate your budget from future FPL rate hikes, making your savings grow more substantial over the 25+ year lifespan of the system. An owned solar system can also be a compelling feature for potential buyers, possibly enhancing your home's resale value.
