Why we don't quote a single Florida average
Averages are the most-requested and least useful number in residential solar. A statewide average blends different system sizes, equipment tiers, roof types, labor markets, sales models, and financing structures. Anchoring on it can make a bad quote look reasonable or a fair quote look expensive.
The more useful skill is being able to look at two proposals and explain why they differ. That is what the rest of this guide is for. When you do see published cost figures, check what they include — whether the figure is before or after incentives, whether it reflects cash or financed pricing, and what year it describes.
System size is the biggest driver
Residential solar is priced largely by capacity, usually expressed in kilowatts of direct current. Capacity is driven by how much electricity you use and how much productive, unshaded roof area you have. A household that uses twice the electricity generally needs a larger system, and a larger system generally costs more.
Production is not the same as capacity. The same size system produces different amounts depending on tilt, orientation, and shading. The Department of Energy’s PVWatts calculator lets you model production for your own address independently of any company’s estimate.6
Sizing based on real usage is covered in how much solar could really save you, and roof constraints in is solar right for your home.
What's actually inside the price
- Panels (modules) — the visible hardware, and rarely the largest share of the total.
- Inverters or microinverters, plus monitoring equipment.
- Racking and mounting hardware, which varies with roof material and layout.
- Labor and installation, including roof complexity, height, and array layout.
- Electrical work, such as a main panel upgrade if your existing service cannot accommodate the system.
- Permitting, inspection, utility interconnection paperwork, and any required engineering.
- Company overhead — sales, marketing, project management, warranty administration.
- Optional additions such as battery storage, critical-load panels, or EV charging.
Two proposals with the same headline capacity can be built very differently. A proposal that does not itemize equipment, warranty terms, and included electrical work is difficult to compare honestly.
Batteries are a separate decision
Adding storage meaningfully increases project cost. Whether it is worth it depends on your reason for wanting it — backup during outages is a different objective from bill management. Decide the solar question and the battery question separately so a battery is not quietly bundled into a comparison between two otherwise different bids. See do I need a battery.
How you pay may matter more than the sticker price
The same system can carry very different total costs depending on structure. Cash purchases avoid financing costs entirely. Loans spread payments over time but add interest, and the Consumer Financial Protection Bureau has documented that solar loans are frequently marketed by dealers with fees embedded in the financed amount, so the cash price and the financed price are not the same thing.2 Leases and power purchase agreements are not purchases at all — you pay for equipment or electricity over a term, often with an escalator that raises the payment each year.
The Federal Trade Commission advises homeowners to get multiple bids, verify licensing, and read lease and power purchase agreement terms closely before signing.3
Structure-by-structure detail is in solar financing options compared.
The two numbers to ask for
For any financed proposal, ask for both the cash price of the system and the total amount you would repay over the full term. If the company will only discuss a monthly payment, that is itself information about how the offer is constructed.
- Cash price of the system as installed, with equipment listed.
- Total amount repaid over the full financing term, including fees and interest.
- Whether the payment or rate escalates, and by how much each year.
- What happens to the agreement if you sell the home.
- Any assumption in the proposal about incentives, production, or future utility rates.
Tax treatment in Florida, as of 2026
Two Florida provisions affect cost. Florida provides a sales tax exemption for solar energy systems and their components.4 Florida law also addresses property tax assessment of qualifying residential renewable energy source devices, which is why adding a system does not straightforwardly raise the assessed value the way some other improvements do.5
The federal picture changed. The IRS states that the Residential Clean Energy Credit equaled 30% of qualifying costs for property installed from 2022 through December 31, 2025, and that the credit is not available for property placed in service after December 31, 2025.1 Treat any current proposal that subtracts 30% from your price as a claim to verify, not a fact. Tax questions specific to your situation belong with a qualified tax professional.

Costs people forget to budget for
- Roof replacement or repair that should happen before installation — see roof replacement before solar.
- Electrical panel upgrades required to interconnect the system.
- Tree trimming or removal to reduce shading.
- Homeowners insurance implications, which you should confirm with your carrier in writing.
- Removal and reinstallation of the array if roof work becomes necessary later.
- Utility interconnection or metering requirements specific to your provider.
What people get wrong
SolarFit™ is a free preliminary education and suitability assessment. It helps you organize your usage, roof, and goals before you start collecting quotes — so proposals are something you evaluate rather than something you react to.
It does not produce a price, a quote, or a guaranteed savings figure. Pricing comes from licensed professionals who have evaluated your specific property.
The most expensive solar mistake in Florida is usually not paying a few hundred dollars too much per kilowatt. It is signing a long financing agreement without knowing the total cost of the money.
Ask for the cash price and the total repaid. Any company that will not show you both has told you something important.
