Solar Calculators for Tampa, Florida

Free tools with illustrative Tampa planning inputs. Replace energy rates and installation costs with your bill and written quote.

Quick answer

Start with your exact utility account and roof design. The 5.5 sun hours and 12.0 cents/kWh below are planning assumptions, not verified current rates for Tampa. Confirm TECO / Duke Energy eligibility and export settlement.

What Tampa homeowners should check

Tampa systems need to handle coastal humidity, strong storms, wind-driven rain, and salt exposure near the bay. Roof condition and wind-rated attachment details should be settled before permitting, especially on tile roofs.

TECO and Duke Energy serve different parts of the region. The correct utility territory determines the interconnection application and billing treatment, so verify it using the service address rather than the mailing city.

At the state level, Florida currently uses full retail net metering. A typical interconnection takes 3–8 weeks, but utility review and local permitting can extend that range. Check current rules before relying on a proposal's export-credit or installation-date assumptions.

What should I verify before signing a solar contract in Tampa?

Confirm that the quote names your actual utility, uses a recent electricity rate, includes measured shade and roof-condition findings, and explains who handles permits and interconnection. Ask the installer to separate guaranteed equipment and workmanship terms from estimated production, incentives, and savings.

Illustrative 5.5 peak sun hours, 14.08% production losses, 12.0 cents/kWh and $2.8/W. The retail-value ceiling assumes every kWh earns retail value; lower export credits reduce it. The cost/value ratio is not a full payback model and excludes repairs, financing and rate changes. No new Section 25D homeowner credit in 2026.
