There is no single price for solar panels in America, and any number that claims to be one is hiding something. The same system that costs one figure in Fresno costs another in Houston and another again in Orlando. This guide compares what solar actually costs in 2026 across the four states we serve, California, Texas, Florida, and Illinois, so you can see where your state lands and why.
Quick Answer: Solar Panel Cost by State in 2026
| State | Price per watt | Representative system | Total before incentives |
|---|---|---|---|
| California | $2.80 to $3.60 | 6 kW | $16,800 to $21,600 |
| Texas | $2.50 to $3.00 | 9 kW | $22,500 to $27,000 |
| Florida | $2.40 to $2.90 | 9 kW | $21,600 to $26,100 |
| Illinois | $3.00 to $3.60 | 8 kW | $24,000 to $28,800 |
Florida is typically the cheapest per watt, Texas is close behind but uses bigger systems, and California and Illinois run highest. The equipment is priced about the same everywhere. What actually moves the number is labor, permitting, utility rules, and which incentives your state still offers.
Why Solar Panel Costs Vary So Much Between States
What stays the same everywhere
Panels, inverters, racking, and wiring are a national commodity. A tier-one module or a hybrid inverter costs a manufacturer about the same whether it ends up on a roof in Sacramento or Tampa, because it ships through the same distribution network. When you see a big gap between two state averages, the equipment is rarely the reason.
What changes at the state line
Four things move once you cross into a different state:
- Labor rates rise and fall with the local cost of doing business
- Permitting and interconnection can be approved same-day in one city and take weeks of plan review in another
- Utility rate structures decide how much your production is actually worth
- Available incentives now come down entirely to state and local programs, since the federal solar tax credit expired for systems placed in service after December 31, 2025
Those four levers, not the panels, explain the spread in the table above.
The National Baseline, and Why “Average” Misleads
Nationally, residential solar in 2026 runs around $3.00 per watt for a quality cash install before incentives. That figure is only useful as a rough anchor. It blends a low-cost market like Florida with a higher labor market like California, then reports the middle as if it described anyone specific.
A more honest way to shop is to start with your state’s typical per-watt range, multiply it by the system size your home actually needs, and use the national number only as a sanity check. Sizing varies more than most people expect, so our guide to what size solar system your home actually needs is worth reading before you convert any per-watt figure into a total.
Solar Panel Cost in California
California is the largest solar market in the country and one of the most expensive to install in, driven by high labor costs and busy permitting offices.
- Price range: $2.80 to $3.60 per watt cash, before incentives
- Representative system: 6 kW, common for California’s smaller average system size
- Total before incentives: $16,800 to $21,600
- What pushes cost up: NEM 3.0 has made a home battery close to standard on new quotes, adding $10,000 to $16,000 but capturing evening value that exporting no longer provides

Solar Panel Cost in Texas
Texas is a lower-cost install market than California, helped by cheaper labor, lighter permitting in many jurisdictions, and heavy installer competition.
- Price range: $2.50 to $3.00 per watt cash, before incentives
- Representative system: 9 kW, larger due to bigger homes and heavy summer cooling loads
- Total before incentives: $22,500 to $27,000
- What to know: Texas has no statewide net metering mandate. What you earn for exported power depends entirely on your utility or retail provider, so plan selection is part of the economics in a way it is not in Florida

Solar Panel Cost in Florida
Florida is often the most affordable of these four states to install solar, thanks to a mature, high-volume market and mild permitting.
- Price range: $2.40 to $2.90 per watt cash, before incentives
- Representative system: 9 kW, larger for year-round cooling
- Total before incentives: $21,600 to $26,100
- What to know: Florida still offers full retail net metering as of 2026, a materially better deal than California’s export rates, which keeps a battery optional for savings rather than necessary

Solar Panel Cost in Illinois
Illinois is a smaller, more seasonal market, and its costs sit at the higher end of this group.
- Price range: $3.00 to $3.60 per watt cash, before incentives
- Representative system: 8 kW, typical to cover usage
- Total before incentives: $24,000 to $28,800
- What to know: Illinois Shines, the state’s Adjustable Block Program, pays homeowners for the renewable energy credits their systems generate. Illinois moved away from full retail net metering for major utilities like ComEd in 2025, so the export math now favors self-consumption and storage

State-by-State Cost Comparison at a Glance
All figures are 2026 cash pricing before incentives. The federal tax credit no longer applies to systems placed in service after December 31, 2025, so these numbers are close to what you actually pay.
| State | Price per watt | System | Cost before incentives | Net metering | Key incentive |
|---|---|---|---|---|---|
| California | $2.80 to $3.60 | 6 kW | $16,800 to $21,600 | Net billing (NEM 3.0), low export value | SGIP battery rebate, property tax exclusion |
| Texas | $2.50 to $3.00 | 9 kW | $22,500 to $27,000 | No statewide mandate, utility buyback varies | Property tax exemption, local utility rebates |
| Florida | $2.40 to $2.90 | 9 kW | $21,600 to $26,100 | Full retail net metering | Sales tax exemption, property tax abatement |
| Illinois | $3.00 to $3.60 | 8 kW | $24,000 to $28,800 | Reduced net metering (ComEd, post-2025) | Illinois Shines credits, property tax special assessment |
Read the columns together, not in isolation. Florida’s low per-watt rate is partly offset by larger systems, while California’s higher rate comes with the strongest storage rebate. The lowest sticker price does not always win once export rules and incentives are factored in.
Turning a State Range Into Your Own Number
A state range tells you whether a quote is in the right neighborhood. It cannot tell you your price, because your roof, your usage, and your utility set that. Model your own system first, then gather matched quotes. A California solar cost calculator lets you plug in your address and usage to see a tailored estimate before you talk to anyone.
When quotes arrive, compare them on the same footing:
- Same system size
- Same panel and inverter tier
- Same warranty terms
- Battery included or excluded consistently across every quote
A cheaper quote that quietly drops the battery or uses lower-tier gear is not actually cheaper. Vetting the company matters as much as the price. Our guide to choosing the best solar installer in California covers the questions that separate a solid installer from a hard sell, wherever you live.
Where Your State Leaves You
Solar panels do not have one national price. They have a price shaped by your state’s labor market, permitting, utility rules, and surviving incentives. California and Illinois sit at the higher end, Texas is in the middle with bigger systems, and Florida is often the most affordable, but the sticker figure only becomes real once you factor in what your utility pays for exported power and which programs you qualify for. When you are ready to see your own number, you can get a free solar estimate built around your home and your utility.
Frequently Asked Questions
How much do solar panels cost on average in 2026?
Nationally, residential solar runs around $3.00 per watt cash before incentives in 2026, but that average hides a wide spread. Florida and Texas tend to sit below it thanks to lower labor and permitting costs, while California and Illinois sit above it. Start from your own state’s typical per-watt range, multiply by the system size your home needs, and treat the national figure only as a sanity check.
Which state is the cheapest for solar, of the ones covered here?
Florida is usually the most affordable of California, Texas, Florida, and Illinois on a per-watt basis, often in the $2.40 to $2.90 range before incentives. Texas is close behind on per-watt cost but tends toward larger systems, so the total can land similar to Florida. California and Illinois generally cost the most per watt.
Do I still get the federal tax credit for solar?
No. The federal residential solar tax credit is no longer available for systems placed in service after December 31, 2025, so 2026 installs generally do not qualify. The incentives that still lower your cost are state and local: California’s storage rebate and property tax exclusion, Texas’s property tax exemption and utility rebates, Florida’s sales and property tax exemptions, and the Illinois Shines program.
Why does the same system cost different amounts in different states?
The equipment costs about the same everywhere because it ships nationally. What changes across state lines are the labor rate, the permitting and interconnection process, the utility’s rate and net metering rules, and the state and local incentives. Those four factors are why an identical system can cost thousands more or less depending on where you live.
Does net metering affect what I pay for solar?
Net metering does not change your upfront install price, but it heavily affects the real value of the system and often whether you add a battery. Florida’s full retail net metering makes exported power worth more, keeping a battery optional. California and Illinois have moved to lower export rates, which pushes many homeowners toward storage, adding to the total cost but improving long-term savings.
How do I know if a solar quote in my state is fair?
Compare the per-watt price against the typical range for your state, then make sure any competing quotes match on system size, equipment tier, warranty, and whether a battery is included. A quote far below your state range may be using lower-tier gear or leaving something out. Modeling your system with a cost calculator first gives you a baseline, and checking the installer’s licensing and reviews protects you from a cheap number attached to poor workmanship.
