Frequently Asked Questions
Is solar worth it in Florida in 2025?
Current federal note: the IRS says the Residential Clean Energy Credit is unavailable for residential property placed in service after December 31, 2025. Do not subtract the former credit from a 2026 residential proposal.
What happened to SunPower in Florida?
SunPower filed for Chapter 11 bankruptcy in 2024 and restructured. The manufacturing arm (Maxeon Solar) is now independent. SunPower's residential division was sold to Complete Solaria. Warranties are still honored, but homeowners should confirm installer credentials and warranty transfer terms before purchasing.
Who are the best local solar installers in Florida?
Top-rated Florida solar companies include Solar Bear, Momentum Solar, Freedom Solar, and region-specific installers. Local installers often offer better pricing ($2.20–$2.80/watt) than national brands, faster permitting turnaround (Florida has a streamlined solar permit process), and more responsive service — always check NABCEP-certified installers.
