Solar power in Florida has been increasing, as the cost of photovoltaics has decreased. Florida adopted a net metering rule which allows any customer generating up to 2 MW to use net metering, with the kilowatt hour surplus rolled over each month, and paid by the utility once a year at the avoided cost rate. This is one of the best net metering rules in the country.
The state's largest photovoltaic plant is the 25 MW DeSoto Next Generation Solar Energy Center, completed in 2009. A 400 MW solar farm is planned for Gadsden County, 200 MW in Hardee County and 100 MW in Liberty County. The 100 MW Sorrento Solar Farm is under construction in Lake County. When the 40 MW Phase I is completed, it will be Florida's largest photovoltaic solar farm. As of February 2013, 40 MW of photovoltaic power plants are under construction and an additional 970MW are planned. The available photovoltaic capacity of the state is estimated at 2,902,000 MW.
Solar energy is the state's most abundant energy resource and estimates have placed the state's potential at 2,902,000 MWs, which would produce about 5,274,479,000 MWh, an amount much larger than the state's total electricity consumption of 231,209,614 MWh in 2010. Florida is one of only two states with no potential for wind power, the other being Mississippi, and will need to either import energy from other states during overcast days and at night, or provide adequate grid energy storage. Most of the potential is from photovoltaics, which provides no storage. The state has some potential for concentrated solar power, but the potential is estimated at 130 MW.
