Is solar worth it in Miami in 2026?
A roof in Miami produces about 1,554 kWh a year per kW of panels. For a home with a $150 monthly bill, a 7.6 kW system costs about $23,469 at Florida's median price and pays for itself in roughly 13.0 years, with no federal tax credit. That is 5% more sun than Jacksonville, the city on our Florida page.

How Miami homes get paid for solar
Export rules are set at the state and utility level, not by the city. Miami is under Florida's full net metering: Investor-owned utilities credit monthly exports against your next bill at the kWh rate under PSC Rule 25-6.065; unused credits are paid out once a year at a lower avoided-cost rate. The full rules, incentives and sources are on theFlorida page.
Why the city matters
Two things change from one city to another in the same state: the sun, which sets how many panels you need, and the utility, which sets what exported power is worth. Miami gets 1,554 kWh per kW a year on a south-facing roof at a 20° tilt, so covering a year of use for a $150 bill at 15.3¢ takes about 7.6 kW, roughly 19 panels of 400 W. Electricity prices in the calculator are the Florida residential average; your utility's rate can be higher or lower, so put your own bill in.
