What home solar costs in Henderson - and the 2026 rules that changed the math
Henderson homeowners searching for solar prices land in a minefield of outdated pages still promising a 30% federal credit. It is gone for 2026 installs. This guide runs the real numbers - marketplace prices, Kentucky rules, and payback without subsidies.
Installed home solar for Henderson homeowners averages about $2.58 a watt across the U.S. marketplace - roughly $30,960 for a 12 kW system before incentives.
The 30% federal solar tax credit ended for installations finished after December 31, 2025 - Henderson systems completed in 2026 get $0 from it.
Under Kentucky's export rules, compensation for surplus power decides the payback - which typically runs 10-14 years on unsubsidized 2026 math.
Henderson plus 8 surrounding towns within 40 km form one installer market of about 169,596 people - quotes should not vary much by town.
Solar pricing is unusually transparent if you know where to look: marketplace data puts the U.S. average at about $2.58 per watt installed. What varies in Henderson is not the hardware - panels are commodities - but installer overhead, sales commissions, and Kentucky's export rules. That is where quotes win or lose.
The single biggest change for Henderson homeowners in 2026: the federal 30% tax credit is gone. A $31,000 system that effectively cost $21,700 in 2025 now costs the full $31,000. That does not automatically make solar a bad buy in Kentucky - but it makes the state rules below matter far more.

The 30% federal tax credit is gone for 2026 installations
The federal Residential Clean Energy Credit (30%) was repealed by the One Big Beautiful Bill Act signed July 4, 2025. Per the IRS, the credit is not available for any property placed in service after December 31, 2025 - and the IRS counts the installation completion date, not the contract date.
Kentucky rules that decide your payback
| Rule | Kentucky status |
|---|---|
| Export compensation (net metering) | Net metering must still be offered, but 2019's Senate Bill 100 replaced 1:1 retail crediting with a dollar-denominated bill credit whose rate the Kentucky PSC sets utility-by-utility in a rate case — generally well below retail — with excess credits carrying forward and never refunded in cash. |
| State incentive | No state-level incentive; utility rebates may apply |
| Sales tax on the system | Not exempt - taxed like any purchase |
| Property tax on added home value | No exclusion on record |
Systems energized before their utility's new PSC net-metering order keep the old 1:1 kilowatt-hour credit for a full 25 years, and that grandfathering runs with the property — it survives a sale of the home — so an older solar house can be worth notably more than a new install.

Why only these platforms
The cheapest bid per watt is not the best bid. Panel warranties run 25 years, but the workmanship warranty dies with the installer - and the post-credit shakeout is closing solar companies every month in 2026. The best quote comes from the company that will still answer the phone in year five.
Solar lead generation is where most industry abuse lives, so this guide only links platforms that show you multiple named installers and let you walk away - never single-installer funnels or phone-blast forms. If a platform falls below that bar it gets removed from every page on this site.
| Platform | What you get | Background |
|---|---|---|
| EnergySage | Side-by-side bids from multiple installers | The largest U.S. solar marketplace; publishes its pricing data publicly |
| Modernize | Matched with vetted local installers | Established home-services network (QuinStreet); installers are screened |
Getting quotes in Henderson
Before requesting quotes, have your last 12 months of electricity bills handy - system sizing should follow your real usage, not a salesperson's template. A bid sized far above your usage is a margin play, especially now that surplus export pays less in most states.
- Your last 12 months of electricity bills - sizing should follow real usage
- Roof age and type - reroofing after panels go up is expensive
- Your utility's export rate under Kentucky rules - it decides the payback
- Whether you want backup power - that is a battery decision, priced separately
- Written itemization: hardware, labor, permits, and any financing dealer fee

Reading a Henderson roof honestly
Marketplace platforms collect bids from multiple KY installers against the same spec, which is the only clean way to compare - same roof, same size, different prices. Getting quotes is free and does not commit you to anything; prices come from the installers, never from this site.

Common questions
Should I lease, get a PPA, or buy?
Buying keeps all savings and any incentives with you. Leases and PPAs put a company's equipment on your roof for 20-25 years, complicate a home sale, and in 2026 any tax benefits they advertise belong to the company under commercial rules - not to you. Read escalator clauses carefully.
Is my roof even suitable for solar?
Three things decide it: orientation (south-facing is best in the U.S., east-west workable), shade (trees or taller buildings across midday hours can sink the math), and roof age (if the shingles have under 10 years left, reroof first - removing and reinstalling panels later costs thousands). Any honest installer assesses all three before quoting a number.
Do I need a battery with my solar?
Not necessarily. Under full retail net metering, the grid effectively stores your surplus for free. Batteries earn their $12,000-16,000 price where export rates are low, outages are common, or time-of-use rates make evening self-consumption valuable.
How do I check if a solar quote is fair?
Divide the total price by the system's wattage. The U.S. marketplace average is about $2.58 per watt installed; $2.30-3.00 covers most fair quotes depending on roof complexity. Above that, ask exactly what you are paying extra for - in writing.
Is there still a federal solar tax credit in 2026?
No. The 30% Residential Clean Energy Credit was repealed effective for systems placed in service after December 31, 2025, per the IRS. Only systems finished by the end of 2025 qualified. State-level incentives are separate and some survive - check the state page in this guide.
How long do solar panels actually last?
Panels are typically warrantied for 25 years of production and commonly outlive it, losing about 0.5% output per year. Inverters are the component that usually needs replacement - typically once, around year 12-15, at a few thousand dollars.
