Frequently asked questions
Do solar panels need a permit in Florida?
Yes. Solar requires a building permit with engineered attachment details and an electrical permit, plus an interconnection agreement with your utility before the system can be energized.
Should I replace my roof before installing solar?
If your roof has fewer than about 10 years of life left, replace it first. Removing and reinstalling an array later commonly costs $3,000-$7,000.
