Is Going Solar in Keystone Still a Good Investment in 2026?
With average electric bills from Tampa Electric Co (TECO) around $195 and climbing, many homeowners in Keystone are looking for ways to control costs. While the 30% federal tax credit for solar installations concluded at the end of 2025, the financial case for rooftop solar remains strong in Florida. This is thanks to excellent state-level incentives and a favorable net metering program that maximizes the value of the energy your system produces. For many, solar is less about a tax credit and more about long-term savings and bill stability.

Estimated Solar Panel Cost in Keystone (2026)
To offset a typical $195 monthly electric bill in the Keystone area, a 10.7 kW solar system is a common size. In early 2026, the estimated upfront cost for a system like this is $24,075.
- Solar-Only System Cost: $24,075
- Payback Period: 10.3 years
Adding a 10 kWh battery for backup power would increase the total cost to around $39,075. The battery provides peace of mind during outages but is not required to achieve significant savings, and it extends the financial payback period to over 15 years.
Incentives & Tax Credits
The Financial Foundation: Florida's Solar Incentives
Even without a federal credit, the economics of solar in Keystone are supported by two key Florida policies:
- No Sales Tax: You will not pay Florida's 6% sales tax on the solar equipment, which saves you over $1,400 on a $24,075 system right from the start.
- No Property Tax Increase: Despite adding thousands of dollars in value to your property, your home's assessed value for tax purposes will not increase because of the solar panels. This is a permanent benefit for as long as you have the system.
These two incentives, combined with TECO's net metering, form the financial backbone of a solar investment in 2026.
Net Metering: Tampa Electric Co

Understanding Net Metering with Tampa Electric Co (TECO)
Tampa Electric's net metering program is essential to solar's value. It allows you to get the full retail value for every excess kilowatt-hour (kWh) of electricity your panels generate and send to the grid. When your system produces more power than your home is using, the meter effectively spins backward, and TECO credits your account. These credits are then used to offset the cost of electricity you draw from the grid at night or on cloudy days. This 1-for-1 exchange makes your solar investment work efficiently, directly leading to lower monthly bills.
Projected Savings
How You Save Money with Solar in Keystone
A 10.7 kW solar system is modeled to generate approximately $1,975 in electricity savings in its first year. These savings are realized by directly powering your home with solar energy and earning credits from TECO for any excess power you send to the grid. The real value grows over time. As utility electricity becomes more expensive in future years, the power your panels produce becomes a more valuable asset, effectively locking in a lower rate for decades. Furthermore, an owned solar system is a durable home improvement that can enhance resale appeal for future buyers.
