Frequently Asked Questions
What solar panels are best for Florida's humidity?
All Tier 1 solar panels (SunPower, Qcells, REC, LG) are rated for Florida's humidity. The more important spec is the PID (Potential Induced Degradation) resistance and the backsheet durability — ask your installer about panel performance data in humid coastal environments. Panels with black polymer backsheets tend to perform better in high-humidity coastal Florida.
How many solar panels do I need for a Florida home?
The average Florida home uses 1,100–1,400 kWh/month. A 5kW system (12–15 panels) generates roughly 600–700 kWh/month in Florida's sun. Most Florida homes need a 10–14 kW system (24–35 panels) to cover their full electric usage, especially if running central AC during summer.
Does hail affect solar panels in Florida?
Standard Tier 1 panels are tested to withstand 25mm (1 inch) hail at 50 mph — not a major concern in most of Florida. Wind load (hurricane winds) is a far bigger concern: verify panels are installed with hurricane-rated racking at the appropriate wind zone for your county.
