2026 Solar & Battery System Costs in Riverview
When considering solar in 2026, homeowners have two main pathways. Understanding the difference is key to maximizing your investment.
- Solar Only System (Basic): A standard 4 kW solar panel system costs about $11,500 before incentives. After the 30% federal tax credit, the net cost drops to $8,050. This option is great for offsetting your daytime energy use but sends excess power back to TECO at a reduced rate.
- Solar + Battery System (Recommended): For energy independence, a solar system paired with a battery costs roughly $23,500. The net cost after the 30% credit is approximately $16,450. This is the preferred choice for hurricane preparedness, as it keeps your lights on during a grid outage. It also lets you store your solar energy to use at night instead of selling it cheap.
Incentives & Tax Credits
Available Solar Tax Credits & Exemptions
Florida homeowners benefit from significant financial incentives that lower the barrier to entry for solar. Your $16,450 net cost for a battery system is possible because of:
- The 30% Federal Solar Tax Credit: This is the most important incentive. You receive 30% of your total system cost (including the battery) back as a credit on your federal taxes.
- Florida Property Tax Exemption: Adding solar panels increases your home's value, but thanks to this exemption, it won't increase your property taxes.
- Florida Sales Tax Exemption: You pay zero state sales tax on the purchase of your solar equipment, saving you hundreds of dollars right off the top.

Understanding Tampa Electric's Net Metering in 2026
TECO's net metering program, updated by state law HB 741, has changed for new solar owners. As of 2026, the utility credits you for surplus energy sent to the grid, but at a rate lower than the full retail price you pay for electricity. This makes a battery system more valuable than ever. By storing your excess solar power in a battery, you can use it yourself in the evening instead of exporting it for a diminished credit, which accelerates your return on investment.
Projected Savings
What Are the Real Monthly Savings on a TECO Bill?
With an average electricity rate of $0.138/kWh in the Riverview area, a properly sized solar system can significantly reduce your monthly payments to TECO. A 4 kW system generates around 6,335 kWh of clean energy annually, leading to estimated savings of about $874 per year. For the average $172 monthly bill, this provides major relief, especially during the long, hot summer months when AC usage is at its peak.
