Solar Panel Installation in Largo FAQs
Is solar worth it in Largo?
The sun is strong (about 1,490 kWh a year per kW, our estimate). Florida’s big investor-owned utilities must credit exports to your next bill under state net metering, so solar can pay well when sized to what you use; city utilities and co-ops set their own, often lower, export credits. See the Florida incentives for the tax rules.
Is there a federal solar tax credit in 2026?
No. The federal 25D credit ended for expenditures after December 31, 2025. Florida has no state income tax credit for solar; the sales-tax exemption and the property-tax rule are separate.
Do I need a permit for solar panels in Largo?
Usually yes, and the utility may need to approve solar and batteries. City of Largo Building Division handles permits in Largo; see the permit information above.
