Indiana’s worth-it verdict now turns on a clock, not a roof. Since the state closed retail net metering, power you use as your panels produce it is worth your full rate while power you export earns less, so the question is when your household consumes. The households that run their lives in daylight, or shift loads there, or store for the evening, are the ones Indiana still pays. Same sun, same panels, different day-shapes, different answers.
The current Indiana question is what time it is when you use electricity.

The Timing Profiles
Your household’s day | What happens to the production | 2026 verdict |
|---|---|---|
Home by day: remote work, retirees, daytime appliances | High self-consumption at full retail value | Worth it for sound roofs you expect to hold past the payback year: 13.5 years at the ceiling, longer once exports are priced, so plan on 15 or more |
Shiftable loads: water heater, pool pump, EV charging at noon | Free load-shifting raises self-consumption before any hardware | Usually worth it after the shifting, sized to the new shape |
Evenings-heavy, storage added | The battery moves noon production into the expensive evening | Conditional yes; the battery must clear its own arithmetic |
Evenings-heavy, no storage, no shifting | Most production exports at the reduced rate | Not as quoted; restructure or wait |
The export mechanics live in Indiana solar incentives, and the price side, judged per used kilowatt-hour, in what solar costs in Indiana.

What the Timing Verdict Requires
- Your usage pattern, from data. If your utility’s customer portal offers hourly interval data, add up what you use between roughly 9 a.m. and 4 p.m. and divide by your total; that share is close to what a right-sized system will self-consume before any shifting. Where hourly data is not available, use the monthly bill and daytime occupancy as the proxy: nobody home on weekdays puts you in the evenings-heavy row of the table above.
- The export rate, named. Indiana pays exports from new systems at 1.25 times the prior-year average hourly MISO price, filed per utility. On record: NIPSCO $0.038333 per kilowatt-hour, effective March 31, 2025, and AES Indiana 3.935¢. Duke Energy Indiana and Indiana Michigan Power file their own, so get the current figure in writing, since it resets every year. Against the 16.58¢ statewide average, which is context rather than any utility’s price, an exported kilowatt-hour earns roughly a quarter of what a self-consumed one avoids; run the real ratio on your utility’s filed residential rate.
- Sizing to the daytime load. Indiana’s typical system is 7.92 kW, sized to the average home’s 901 kWh a month, and here it flexes down as often as up, because every kilowatt-hour beyond the daytime load exports at the utility’s filed rate instead of offsetting retail.
- The battery on its own line. Price it on its own: the battery’s installed cost divided by the annual value of the kilowatt-hours it moves from the 3.8 to 3.9 cent export rate up to your retail rate is its payback, and that has to land inside the battery’s warranty life.
- Clean financing. The federal residential credit is $0 for host-owned systems whose installation is completed after December 31, 2025, under Public Law 119-21, and dealer fees do not care about your load shape. Third-party ownership sits in legal gray territory in Indiana; where a lease or power purchase agreement is offered, the company may qualify for the separate Section 48E business credit under current deadlines, and whether any of that value reaches your payment depends on the contract, so ask for both in writing.

When Indiana Solar Is Not Worth It
- The quote never asked when you use power. In this state that is the whole question; a proposal without it is a brochure.
- Evening-heavy, storage refused, loads unshiftable. The rules price that shape against you.
- A roof on borrowed time. No timing fixes the substrate.
- A $0-down contract built on pre-2022 math. Its assumptions died with retail net metering; see what free solar really means in Indiana.

Frequently Asked Questions
Yes, solar panels are worth it in Indiana for daytime-heavy households, and for others willing to shift loads or add storage. Since Indiana closed retail net metering, self-consumed power carries the value, so the verdict follows your usage timing more than your roof.
It can be. Power used as it is produced avoids your full retail rate regardless of export rules, which is why timing, load shifting, and storage became the levers that decide the modern Indiana answer.
Often, with adjustments: shifting water heating, pool pumps, or EV charging into daylight raises self-consumption at no cost, and a battery closes the remaining gap where its own arithmetic clears.
Pros: solid sun, solid sun and full retail value on every self-consumed kilowatt-hour, full retail value on every self-consumed kilowatt-hour, and a strengthened battery case. Cons: below-retail export rates, no state credit, and pitches still using the old math.
More often than in most states, because it converts export-rate production into retail-rate consumption every day. It must still clear its own line-item arithmetic against that gap and its warranty life.
A 7.92 kW system at $24,235 gross ($3.06 per watt as of March 1, 2026) produces about 10,811 kWh a year. If every kilowatt-hour offset power at the 16.58 cent statewide average, which is ranking context rather than any utility’s price, the value would be about $1,792 a year and the simple payback about 13.5 years, and that is the ceiling. Real Indiana paybacks run longer, because each tenth of production that exports at the 3.8 to 3.9 cent filed rates instead of being used costs roughly $137 a year at that benchmark and adds about a year to the payback. Run yours on your utility’s filed residential rate, your measured daytime share, and your utility’s current export rate, then rerun it with the export rate reduced; the spread is your exposure.
Methodology: payback figures use the state benchmark of $3.06 per watt as of March 1, 2026, no federal residential credit for host-owned systems, exports at the utility’s filed EDG rate under IC 8-1-40, rate escalation at the state five-year average of 3.26%, 0.5% annual panel degradation, and a 25-year horizon. Per-utility export rates reset annually, so confirm your utility’s current filed figure before relying on any projection. Reviewed August 2026.
