It's a proven way to reduce your monthly expenses and secure your power supply.

Benchmark Cost Analysis

Solar Installation Costs in Carrollwood (2026)

The cost of going solar depends on whether you include a battery for backup power. A system designed to offset a $172 monthly TECO bill costs roughly $11,500 before incentives. Here is the final cost you can expect to pay:

  • Net Cost (Solar Only): After applying the 30% federal tax credit, the price of a typical system is around $8,050.
  • Net Cost (Solar + Battery): For homeowners wanting resilience against power outages, a combined system costs approximately $16,450 after the 30% credit. This is increasingly popular in the Tampa Bay area for storm readiness.

The payback period for a solar-only system is just over 9 years, after which you enjoy decades of free power.

Incentives & Tax Credits

Federal & State Solar Incentives

The primary financial incentive is the 30% Residential Clean Energy Credit, a dollar-for-dollar reduction of your federal income taxes. Florida also provides significant benefits by making solar equipment fully exempt from state sales tax and property tax assessments, saving you money upfront and every year after.

Understanding TECO's Net Metering Program

Like other Florida utilities, TECO's net metering program was updated by HB 741. For systems installed in 2026, the utility credits you for surplus energy sent to the grid, but at a rate slightly lower than the full retail price you pay. This policy makes using your own solar power onsite more valuable than exporting it, giving a clear advantage to homes with a battery that can store that daytime energy for evening use.

Projected Savings

Your Estimated Savings with TECO

A properly sized solar array in Carrollwood can produce about 6,274 kWh of electricity per year, saving the average homeowner $866 annually on their TECO bill. As utility rates continue to climb, these savings will become even more substantial over the 25+ year lifespan of the system.

Local Questions Answered

Will summer thunderstorms in Carrollwood damage the panels?
No, panels are designed for this climate. They are tested to withstand hail and high winds, and production is based on annual sunlight, not just perfect weather. They still produce significant power on overcast days.
Is my Carrollwood home a good candidate for solar?
Most homes with a roof that gets several hours of direct, unshaded sunlight are excellent candidates. A south-facing roof is ideal, but east and west-facing roofs also perform very well. Our calculator can give you a preliminary assessment.
Do I need approval from Hillsborough County to install solar panels?
Yes, your installer will handle all the necessary permitting with Hillsborough County and TECO to ensure your system is properly connected and compliant with all local building and electrical codes.
