Solar quotes can swing by thousands of dollars depending on your state, your roof, and what your installer bundles into the price. This guide breaks down what homeowners in California, Texas, Florida, and Illinois are actually paying for solar installation in 2026, what drives the cost per watt up or down, and how to tell a fair quote from an inflated one before you sign anything.
Solar quotes rarely agree with each other. One installer says $18,000. Another says $27,000 for what looks like the same system. The difference usually is not the panels themselves. It is what gets bundled into the price, and where you live.
This guide breaks down what homeowners in California, Texas, Florida, and Illinois are actually paying for solar in 2026, what drives your price per watt up or down, and how to spot a fair quote before you sign anything.
Solar installers price systems by cost per watt, and in 2026 the national range runs from about $2.30 to $3.60 per watt before incentives. Panels themselves are a small slice of that number. Labor, permitting, inspection fees, and installer overhead make up more than half the total cost of a typical project.
That is why two homeowners with identical roofs and identical system sizes can get quotes thousands of dollars apart. The gap almost never comes from the hardware.
California installations typically run $2.60 to $3.70 per watt, among the highest in the country. High labor costs, layered permitting requirements, and HOA reviews in many communities all add to the price. Texas and Florida sit closer to $2.20 to $2.90 per watt, thanks to faster permitting and heavier installer competition. Illinois lands in between, averaging $2.50 to $3.00 per watt.
Here is the part most quotes leave out: a higher price per watt in California does not automatically mean a worse deal. California electricity rates are among the highest in the nation, often 30 to 32 cents per kilowatt hour and up more than 40% over the last five years. That gap between what you pay the utility and what solar costs you is what actually determines your payback period, not the sticker price alone.
Most California homeowners need a 6kW to 8kW system to offset a typical bill, which lands between $18,000 and $28,000 before any incentives. In higher cost markets like the Bay Area or parts of Los Angeles County, an 8kW system with premium equipment can push past $29,000. The tradeoff is that California's high utility rates usually mean a faster return on that investment than the sticker price suggests. California's permitting complexity is also why it helps to understand how long solar installation takes before you budget your timeline alongside your cost.
Texas and Florida both benefit from streamlined permitting and a large pool of competing installers, which keeps per watt pricing lower, generally $2.20 to $2.90. A 7kW system in either state typically runs $15,400 to $20,300. Florida homeowners also see strong solar production nearly year round, which helps offset the region's relatively lower electricity rates.
Illinois averages $2.50 to $3.00 per watt, with a 7kW system typically costing $17,500 to $21,000. Illinois also has an active SREC market, which can meaningfully improve the long term economics even though the state gets less annual sun than California, Texas, or Florida.
Solar panels themselves account for roughly 12% to 13% of a total installation cost. The rest goes to inverters, racking, wiring, labor, design, permitting, and installer profit. This is why comparing quotes on price per watt, not total dollar amount, is the only way to actually compare two installers fairly. It also explains why one of the biggest factors in overall value is not the panels at all, but local solar installers you can trust to execute the design, permitting, and interconnection correctly the first time.
Under California's current billing structure, a solar only system without battery storage rarely makes financial sense anymore. That shift traces back to the NEM 3.0 billing changes, which reduced how much utilities pay for excess solar exported to the grid. Battery storage typically adds $8,000 to $20,000 depending on capacity, so before you commit to a system size, it is worth understanding whether solar batteries are worth the extra cost for your specific usage pattern.
Most solar companies resell panels they have never touched, adding a markup at every step between manufacturer and installer. US Power works directly with Qcells as a factory-direct partner, which removes that layer of markup and passes the savings to you. That same direct relationship is also why you can get your free, no-obligation solar estimate and see real numbers for your home instead of a generic national average.
Every US Power installation is backed by CSLB licensed consultants and a 25-year comprehensive warranty covering panels, workmanship, and performance. That warranty matters more than it might seem when you are comparing quotes. A cheaper install with a thin warranty can cost you far more over 25 years than a slightly higher upfront price backed by real coverage. It is one of the reasons US Power has earned 200+ five-star Google reviews from homeowners across California, Texas, Florida, and Illinois.
The federal residential tax credit ended for owned systems on December 31, 2025, which changed the math for a lot of homeowners. But utility rates did not stop climbing. Most California homeowners still save $100 to $250 a month once their system is live, and Texas and Florida homeowners typically see a full return on their investment within 7 to 10 years, even without the federal credit. Leases and power purchase agreements can still access a commercial credit, which is worth asking about if a $0 down option fits your budget better than a cash purchase.
Before deciding between cash, loan, lease, or PPA, it helps to understand what to expect when buying solar panels under each option, since the financing choice can move your effective cost per watt by 20% or more over the life of the system.
National averages are a starting point, not a quote. Your real cost depends on your roof, your usage, your state, and how you choose to finance the system. The only way to know your actual number is to get a design built around your home, not a generic estimate pulled from industry data.
US Power backs every installation with factory-direct Qcells pricing, CSLB licensed consultants, and a 25-year warranty, so the number you see upfront is the number you can trust.
