Solar power in Florida has been increasing, as the cost of solar power systems using photovoltaics (PV) has decreased in recent years. Florida has low electricity costs compared with other states, which makes individual solar investment less attractive. Florida ranks ninth nationally in solar resource strength according to the National Renewable Energy Laboratory and tenth in solar generation by the Solar Energy Industries Association.

In 2006, the State of Florida enacted the Florida Renewable Energy Technologies and Energy Efficiency Act, which provided consumers with rebates and tax credits for solar photovoltaic systems. The program was closed in 2010. Later, the Florida Public Service Commission mandated that the state's large utilities offer individual solar rebates. The program opened in 2011 and was closed in 2015 after the Commission deemed it to not be cost-effective for non-solar customers.

In 2008, Florida adopted a net metering rule that allows any electric utility customer generating up to 2 MW (2,000 kW) of power to use net metering, which provides a retail rate credit for kilowatt-hours of electricity delivered to the utility, rolled over from month to month, and paid out in cash by the utility once a year at the avoided cost rate.

The federal Residential Energy Efficient Property Credit (income tax credit on IRS Form 5695) for residential PV and solar thermal was extended in December 2015 to remain at 30% of system cost (parts and installation) for systems put into service by the end of 2019, then 26% until the end of 2020, and then 22% until the end of 2021. It applies to a taxpayer's principal and/or second residences, but not to a property that is rented out. There is no maximum cap on the credit, and the credit can be applied toward the Alternative Minimum Tax, and any excess credit (greater than that year's tax liability) can be rolled into the following year.

In 2009, Florida Power & Light built the state's first solar power plant, the FPL DeSoto Next Generation Solar Energy Center. At the time, the 25-MW plant was the largest of its kind. In 2010, FPL built the world's first hybrid solar-natural gas energy center.

One of the state's largest solar plants is the 75 MW FPL Martin Next Generation Solar Energy Center, in Martin County operated by Florida Power and Light. It was the world's first hybrid solar-natural gas energy center and is a concentrated solar power (CSP) plant using solar thermal instead of photovoltaic technology. No additional CSP plants are under development in Florida, although in 2007 a 300 MW Fresnel CSP plant had been planned.

The state's largest photovoltaic plant was the 25 MW DeSoto Next Generation Solar Energy Center, operated by Florida Power and Light, completed in 2009. Florida Power and Light also operates the Space Coast Next Generation Solar Energy Center, a 10 MW photovoltaic facility near the Kennedy Space Center.

The 100 MW Sorrento Solar Farm was expected to become Florida's largest photovoltaic solar farm with 40 MW of photovoltaic capacity already under construction in Lake County. However the company Blue Chip Energy became insolvent and the equipment and farm site were sold at a public auction in 2013.
