Will solar raise my St. Lucie County property taxes?
No. Under Florida law (s. 193.624), the value a solar system adds to a home isn't counted in its assessed value. If you're unsure whether anything needs to be filed, ask the St. Lucie County Property Appraiser.
Solar equipment is also exempt from Florida sales tax, so it's already left out of the installed price.
How does solar work with FPL in St. Lucie County?
FPL credits the solar you send to the grid as a kWh credit at the full retail rate. Unused credits roll forward for up to 12 months, and anything left at year-end is paid out at only a few cents per kWh, so systems are sized to cover a year of use. Solar can't take a bill below the monthly minimum ($30 at FPL).
