Yes, for most homeowners with above-average electric bills, solar still pays for itself here, usually within 10 to 17 years, even after the federal tax credit ended for homeowner purchases in 2025. Two state tax breaks and falling equipment prices help close the gap.
Indiana Solar Panel Costs in 2026
Panel costs here currently run between roughly $2.80 and $3.60 per watt installed, before any incentives. A typical residential system falls between 8 and 13 kilowatts (kW), which puts most homeowners somewhere between $20,000 and $40,000 before tax breaks.
Pricing varies by installer, panel brand, and roof complexity. A steep roof, extra electrical panel upgrades, or a shaded lot can all push the number higher than a straightforward south-facing install.
If your roof is more than 12 to 15 years old, budget for roof replacement before solar. Pulling panels back off a failing roof a few years later almost always costs more than doing the work upfront, and most reputable installers will flag this during a site visit.
Residential solar panels Indiana homeowners install most often sit in the 8 to 10 kW range, sized to offset 80 to 100 percent of a typical household’s usage rather than to sell power back at scale.
Solar Incentives Indiana Homeowners Can Still Claim
The federal 30 percent tax credit for homeowner-purchased systems expired after 2025, which changes the math significantly. That makes the remaining state-level breaks more important than ever for anyone running the numbers.
Two exemptions do most of the heavy lifting locally:
| Incentive | What It Covers | Approximate Value |
| Solar property tax exemption Indiana | Excludes added home value from property tax assessments | 100% of the system’s added value |
| Solar sales tax exemption Indiana | Waives sales tax on qualifying solar equipment | 7% of equipment cost |
| Local utility or city rebates | Varies by provider or municipality | Case by case |
| USDA REAP grants | Rural properties and small farms | Up to 50% of eligible project cost |
Without the federal credit, these two exemptions and any local rebate become the main levers for lowering your net cost. The U.S. Department of Energy’s solar guidance and the DSIRE incentive database are both worth checking directly, since rebate programs shift year to year.
AES Indiana Net Billing and Indiana EDG Solar Policy
A 2017 state law phased out traditional net metering for new solar customers, and by 2022 all five major investor-owned utilities had stopped accepting new net metering enrollments. This net metering phase-out is one of the biggest factors homeowners underestimate when they first look into going solar.
New systems today, including customers on AES’s net billing program, are enrolled instead in what’s officially called an Excess Distributed Generation program, or EDG for short. Under EDG, only the electricity your panels export at the exact moment they overproduce gets credited, and it’s paid at a wholesale electricity credit rate rather than the retail rate you pay for power you pull from the grid.
That excess distributed generation rate typically lands somewhere around 3 to 5 cents per kilowatt-hour, compared to a retail rate closer to 14 to 15 cents. In practice, self-consuming your own solar power is worth far more than exporting it, which changes how a system should be sized and how a battery pencils out.
Homeowners who bought or signed before the cutoff dates may still be grandfathered into full retail net metering through 2032 or 2047, so it’s worth confirming your status with AES or your own utility before assuming EDG applies to you. The state’s utility regulator publishes utility-specific rate filings if you want to see the exact math behind your credit.
Duke Energy Solar Credits and Other Utility Programs
Duke Energy solar credits follow the same EDG structure described above, since Duke Energy is one of the five utilities that moved off net metering. CenterPoint, I&M, and NIPSCO round out the list, with NIPSCO running its own feed-in tariff structure for certain enrolled systems instead of standard EDG.
None of this changes the underlying math dramatically between utilities, but two neighbors on different grids can still see noticeably different credit rates. Combine that with ongoing utility rate increases on the retail side, and the case for maximizing self-consumption over export gets stronger every year.
Indiana Solar ROI and Payback Period
Working out whether the numbers pencil out starts with your average monthly kWh usage, since that determines how large a system you actually need rather than how large a salesperson wants to sell you. Pull the last 12 months from your utility account if you can, since usage swings seasonally with heating and cooling.
Solar panel payback period Indiana estimates generally cluster between 10 and 17 years depending on your utility, roof orientation, and local sun exposure, which averages around 4 to 4.7 peak sun hours a day. Homes paying $130 or more per month, with an unshaded south-facing roof, tend to land on the shorter end of that range.
| System Size | Approx. Cost Before Incentives | Typical Payback |
| 5 kW | $17,000–$20,500 | 11–14 years |
| 8 kW | $22,500–$29,000 | 10–13 years |
| 12 kW | $34,000–$40,000 | 12–17 years |
Getting solar system sizing right matters more than chasing the biggest possible array, since an oversized system under EDG exports more power at the low credit rate instead of offsetting your own usage. Before signing anything, it’s also worth reading through the hidden fees buried in some contracts, since permitting, monitoring, or early payoff charges aren’t always obvious in a sales presentation.
Off-Grid Solar Indiana vs. Grid-Tied Systems
Most homeowners choose a grid-tied solar array, which stays connected to the utility and relies on EDG credits for any excess production. It’s simpler, cheaper upfront, and doesn’t require battery backup to keep the lights on.
These setups are far less common and generally only make financial sense for rural properties without practical utility access, since they need enough battery capacity to cover multiple cloudy days.
Solar battery storage ROI is a separate calculation from panel ROI entirely, and it usually takes longer to pay back on its own unless you’re specifically paying for backup power during outages.
If you’re financing a battery through a loan, it’s worth understanding how solar loan disclosures work under federal lending law before signing anything.
Best Solar Installers Indiana Homeowners Trust
The installers homeowners recommend most tend to share a few traits: they’re licensed and insured, they give a written, itemized quote instead of a verbal estimate, and they don’t pressure you to sign same-day. Get at least three quotes and compare cost per watt, not just total price.
National names like Sunrun and Tesla operate locally alongside smaller regional installers, and it’s reasonable to research how each company handles complaints before committing. Watch for classic solar sales fraud tactics, like inflated savings projections or claims that a rebate expires the same day you meet with a rep.
If a contract does go wrong after signing, homeowners generally have a short window to cancel during the standard cooling-off period, and there are established paths to recover a refund from a solar company that misrepresented savings or performance.
Selling a home later with an existing lease still attached also has its own wrinkles, so it’s worth understanding how a transfer works at resale before you sign a lease in the first place.

Frequently Asked Questions
Is solar actually worth it here in 2026?
For most homeowners with monthly bills above $130 and a decent south-facing roof, yes. The math gets tighter with heavy shading, a small roof, or very low electric bills.
How long does it typically take to break even?
Most homeowners break even in 10 to 17 years, depending on system size, utility, and how much of their own production they use versus export.
What incentives are left since the federal credit ended?
A 100 percent property tax exemption on the added system value and a 7 percent sales tax exemption on equipment are the two main state-level breaks still active.
Does my utility still offer true net metering?
Only if your system was installed before the applicable cutoff date and you’re grandfathered in. New installations are enrolled in EDG instead, at a lower credit rate.
Is going off-grid a realistic option?
It’s possible but expensive, since you need enough battery storage to ride out multiple cloudy days. Most homeowners are better served staying grid-tied.
