Since 1975 · Holly Hill, Florida
Fifty-plus years of Florida sunshine.
International Sun Protection, Inc., dba Solar-Fit, has been installing solar across Volusia, Flagler, St Johns, Putnam, Clay, Duval and Nassau counties since before most of our competitors existed. Bill still answers the phone, and his daughter Kim Brooks is now President of the company.
The story
Built here. Still here.
We started fitting Florida homes with solar in 1975, before tax credits, before net metering, back when a solar water heater was the whole industry. Fifty-plus years later we design, engineer and install every system with our own crews, from pool heaters to fire stations.
That longevity is the warranty behind the warranty: a promise is only as good as the company still being around to keep it.
