With average Duke Energy bills hitting $172.50, many homeowners in Buenaventura Lakes are looking for a permanent solution. That hot, humid Central Florida summer means your AC runs constantly, but it also means your roof is a prime source of energy. So, how much does it actually cost to switch to solar in 2026?
Benchmark Cost Analysis
Solar + Battery System Costs in Buenaventura Lakes
A full solar and battery backup system is the most common choice for new installations. It allows you to store daytime energy for use at night and protects you from grid outages during hurricane season. Expect a total gross cost around $23,500 for a typical system.
After claiming the 30% federal tax credit, the effective cost drops to approximately $16,450. While a smaller solar-only system might seem cheaper upfront (around $8,050 net), the lack of a battery means you sell your excess power to Duke for a reduced rate, significantly cutting your long-term savings under Florida's current rules.
Incentives & Tax Credits
Tax Credits & Incentives Available in 2026
Florida homeowners have several powerful incentives that reduce the upfront cost of going solar:
- Federal Solar Tax Credit: A credit worth 30% of your total system cost, which you can claim on your federal income taxes. For a $23,500 system, this is a $7,050 credit.
- Florida Sales Tax Exemption: You pay zero sales tax on the purchase of your solar equipment, saving you over $1,400 right away.
- Property Tax Exemption: Your home's value will increase, but your property taxes won't. The added value from the solar installation is 100% exempt.

Understanding Duke Energy's Net Metering Policy
Florida's energy policy, updated by HB 741, has changed how Duke Energy compensates solar owners. Under the current Net Metering program for new customers, any excess power you send to the grid is credited at a rate lower than what you pay for electricity. This is why having a battery is so critical. It lets you store that excess power for yourself, essentially 'selling' it to your own home at the full retail rate and guaranteeing the best possible return on your investment.
Projected Savings
How Much You Can Save on Your Duke Energy Bill
A properly sized solar system is designed to offset the majority of your energy consumption. Based on a typical 1,250 kWh monthly usage in Osceola County, homeowners can expect to save around $857 per year. Adding a battery ensures you maximize these savings by using your own stored energy during peak evening hours instead of buying expensive power from Duke. Over 25 years, that amounts to over $21,000 in saved electricity payments, even before factoring in future rate hikes from the utility.
