Solar Panel Installation in Florida

How a solar installation actually runs in Florida

A residential solar project in Florida is four distinct stages, and the permitting and utility steps take longer than the physical install. Panels usually go up in one to two days. Getting to that day is the part homeowners underestimate.

1. Site and structural assessment. We measure usable unshaded roof area, confirm rafter spacing and sheathing condition, and check the age of the roof covering. A roof with fewer than seven or eight years of service life left should be replaced before panels go on, not after.
2. Production modelling and design. Florida averages roughly five to five and a half peak sun hours per day, but orientation, pitch and shading from mature oaks or neighbouring two-storey homes change the result far more than most people expect. We model the array against twelve months of your actual utility usage, not a state average.
3. Permitting. Every Florida county and most municipalities require a combined building and electrical permit with engineer-sealed attachment details. In Miami-Dade and Broward, which sit inside the High-Velocity Hurricane Zone, every component in the mounting system needs a current Notice of Acceptance or Florida Product Approval, and the wind-uplift calculations are reviewed line by line.
4. Interconnection and permission to operate. Your utility, whether that is FPL, Duke Energy Florida, TECO, JEA or a municipal provider, has to approve the interconnection application and swap the meter. The system cannot legally be energised until the local inspection passes and the utility issues permission to operate.

What determines the size of your system

System sizing is driven by consumption, not roof size. The loads that move the number most in Florida homes are air conditioning, pool pumps, electric water heating and, increasingly, EV charging. A 2,400 square foot home in Tampa with a variable-speed pool pump and a heat pump water heater has a very different profile from an identical home in Naples running a single-speed pump and a gas range.

• Roof orientation and pitch. South-facing planes produce the most annual energy; east and west split production across the morning and afternoon, which can suit time-of-use rates better.
• Shading. Even partial shading on one module affects a string. Module-level electronics limit the damage but do not eliminate it.
• Available unshaded area. Fire setbacks and required roof access pathways reduce usable area, sometimes by a third on complex hip roofs.
• Future load. If an EV or a heat pump is likely within five years, sizing for it now is cheaper than adding a second array later.

Florida incentives that still apply

Federal residential incentive rules changed at the end of 2025, so any quote that leans on an expired federal credit should be treated with suspicion. The Florida-level benefits below are state law and are not affected.

• State sales tax exemption. Florida Statute 212.08(7)(hh) exempts solar energy systems and their components from state sales tax. It is applied at purchase rather than claimed later.
• Property tax treatment. Florida Statute 193.624 excludes the added value of a qualifying renewable energy source device from the assessed value of residential property, so a solar array does not raise your property tax bill.
• Net metering. Each investor-owned utility runs its own approved tariff. Export credit rates and true-up periods differ, which is why we model against your specific utility rather than a generic assumption.

None of the above is tax advice. Confirm your own position with a licensed tax professional before signing anything.
