30% of the median — the rest is material, disposal and permit.

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.
