Solar in Port St. Lucie: What Homeowners Should Know
Port St. Lucie sees an average of 5.7 peak sun hours per day, which is what ultimately determines how much electricity a rooftop system produces here. A standard 8 kW system (about 20 panels) generates roughly 13,315 kWh each year in Port St. Lucie — and paired with Florida's local electricity rate of $0.135/kWh, that's where the savings come from.
At those numbers, a Port St. Lucie homeowner saves about $150/month ($1,798/year). Against a $22,400 system cost (about $21,400 after Florida state incentives), that works out to a payback of about 11.9 years, after which the system produces essentially free power for two decades — an estimated $40,000 in lifetime savings. Note: the 30% federal tax credit expired at the end of 2025 for purchased systems, though a solar lease or PPA can still pass it through. The local grid is served by Florida Power & Light, whose net metering policy directly affects how much credit you earn for surplus power.
