What Indiana still offers after the federal credit ended
Every incentive on this page is verified against Indiana government sources - and the expired ones salespeople still quote are called out.
The 30% federal solar tax credit ended for installations finished after December 31, 2025 - New Castle systems completed in 2026 get $0 from it.
Under Indiana's export rules, compensation for surplus power decides the payback - which typically runs 10-14 years on unsubsidized 2026 math.
Installed home solar for New Castle homeowners averages about $2.58 a watt across the U.S. marketplace - roughly $30,960 for a 12 kW system before incentives.
If a salesperson in New Castle tells you a 30% federal tax credit applies to your 2026 installation, they are quoting a dead law. What may still exist: Indiana's own incentives and tax treatment, listed below, and lease/PPA arrangements where a company claims commercial credits - in which case the credit belongs to them, not you.
Leased and PPA systems deserve extra scrutiny in 2026: the sales pitch often bundles 'tax savings' that now accrue to the leasing company under separate commercial rules - not to you. Get every claimed saving in writing, attributed to a specific law, before signing a 20-25 year contract.

Indiana rules that decide your payback
| Rule | Indiana status |
|---|---|
| Export compensation (net metering) | Retail net metering is closed to new residential customers in Indiana; a homeowner going solar in 2026 takes an "excess distributed generation" (EDG) tariff under which only the electricity that flows back to the grid (outflow, measured instantaneously against on-site use) is credited, at a commission-approved rate equal to the supplier's average marginal price of electricity during the most recent calendar year multiplied by 1.25 — well below the retail rate the customer pays for inflow. |
| State incentive | No state-level incentive; utility rebates may apply |
| Sales tax on the system | Not exempt - taxed like any purchase |
Netting is instantaneous rather than monthly — only power exported at the exact moment production exceeds household use earns the low EDG credit, so self-consumption matters far more than under old net metering; and any unused EDG credit balance is forfeited (passed back to other ratepayers) when the customer stops taking service at that premises.

What this means for New Castle roofs
Whether solar still pays in Indiana after the federal credit's end comes down to arithmetic, not ideology: installed cost (about $2.58 a watt at the marketplace average), what your utility pays for exports, and how much of your generation you use yourself. High self-consumption - daytime usage, EV charging, batteries - is now the biggest lever.

Getting New Castle quotes
Marketplace platforms collect bids from multiple IN 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
What happens if my installer goes out of business?
Panel and inverter warranties come from the manufacturers and survive, but the workmanship warranty usually dies with the company. That is a real risk in the post-credit shakeout - prefer installers with years of local history, and get manufacturer-backed workmanship coverage where offered.
How much does home solar cost in 2026?
The U.S. marketplace average is about $2.58 per watt installed - roughly $15,500 for a 6 kW system and $31,000 for 12 kW, before any state incentives. Quotes meaningfully above that level deserve a written explanation of what justifies the premium.
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.
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.
Does solar raise my property taxes?
It depends on the state - many exempt solar's added home value from property tax, others do not, and some exemptions have expiration dates. This guide's state page lists the verified rule and source for your state.
