Not in Indiana?

Indiana shut the net-metering door in July 2022, and most sales pitches never mention it. New solar at the five big utilities earns Excess Distributed Generation credits of roughly 3 to 5¢ per exported kilowatt-hour against 14 to 17¢ retail power. That is not a reason to skip solar; it is a reason to size it to what your house uses. EcoGen America runs Indiana math the way the tariff actually reads.

In Indiana, the Pitch Skips What 2022 Changed.

Indiana shut the net-metering door in July 2022, and most sales pitches never mention it.

New solar at the five big utilities earns Excess Distributed Generation credits of roughly 3 to 5 cents per exported kilowatt-hour, against retail power at 14 to 17 cents.

That is not a reason to skip solar; it is a reason to size it to what your house uses, because the kilowatt-hour you consume yourself is worth three to five times the one you export.

EcoGen America runs Indiana math the way the tariff actually reads, and checks each quote for crediting the utility no longer offers.

Self-Use Sizing

EDG credits pay a fraction of retail, so we size Indiana systems to the home's own usage and treat exports as a rounding line, not the plan.

Quote Analysis

Built-in checks for net-metering assumptions that ended in 2022, per-utility EDG rates, and paybacks quoted against the wrong tariff.

Local Policy

We track EDG rate updates at the five big Indiana utilities and the retail rates that decide the self-use math.

The 3.9¢ Line: Indiana EDG Math, Itemized

Three regimes now coexist on Indiana roofs. Every quote you read belongs to exactly one of them:

Regime
What Power Is Worth
Who Gets It
Self-consumption
Full retail avoided, 14 – 17¢/kWh
Every system, automatically; the entire case for new Indiana solar
EDG exports
125% of avoided cost; ~3.935¢ at AES, roughly 3 – 5¢ statewide
All new systems at the five investor-owned utilities since July 2022
Grandfathered net metering
Full retail for exports
Pre-2018 systems until July 1, 2047; 2018-2022 systems until July 1, 2032
EDG credit values per utility filings as of July 2026; confirm your utility’s current rate, they differ and they move.

The corollary for home buyers: a house with 2019 panels carries retail netting until 2032. That grandfather clause is a real asset, and it transfers with the meter, not the seller.

Audit, Size, Verify: Buying Solar in EDG-Era Indiana

1

Audit

Pull 12 months of bills and find your daytime usage. In an EDG state, that number, not your roof area, sets the right system size.

2

Size

Build to consume what you generate. Oversizing manufactures 4¢ exports with money that deserved 15¢ work.

3

Verify

EDG rates differ across AES, Duke, CenterPoint, I&M and NIPSCO. Make the quote name your utility's current filed rate.

Indiana Contract Checks

Indiana Quotes: Four EDG-Era Checks

The 2022 rule change made old sales scripts obsolete. These four lines catch the ones still circulating.

Clause to verify: Find the export rate in the model; it should read as an EDG credit near 3 – 5¢, named per your utility.
Clause to verify: Compare projected kWh to your 12-month usage and make the installer defend any overshoot.
Clause to verify: Ask for the payback with every tax-credit line struck; Indiana math must stand on the bill savings.
Clause to verify: Both numbers side by side, and the spread explained before signing.
Verify your paperwork

Four checks, any Indiana quote. The good ones survive all four.

Grandfathered Until 2032 or 2047: Indiana’s Two Clocks

Indiana’s transition rules created two protected classes of solar homes, and both matter when houses change hands:

  • Systems installed before 2018 keep full retail net metering until July 1, 2047. On a resale, that is two more decades of premium export value attached to the house.
  • Systems installed 2018 through mid-2022 keep it until July 1, 2032. Still valuable, and still transferable with the property.
  • Systems installed after July 2022 were never in the program; they earn EDG credits from day one, and nothing changes at resale.
  • Replacing or expanding a grandfathered system can end its protection. Owners of pre-2022 arrays should price upgrades against the netting they would forfeit.

If you are shopping for a home with panels in Indiana, the install date is worth asking for in writing. The difference between a 2017 array and a 2023 one is a decade-plus of retail-rate exports.

When Indiana Solar Should Wait

Post-2022 Indiana math is workable, not universal. Hold off if:

  • Nobody is home using power at midday and a battery is not in the budget. EDG exports will not carry the project alone.
  • The quote only pencils with net metering or tax credits. Neither exists for a new 2026 Indiana purchase.
  • Your roof shades out through the middle of the day. Self-consumption states need midday production; get a shade study first.
  • You own a grandfathered system and are tempted to expand. Price the upgrade against losing retail netting before signing anything.
  • Your bills are small. At $70 a month there is little for the system to offset, and the payback stretches past patience.

Steady daytime load and clear sun? Indiana still works. It just works quietly, on your own meter, the way the tariff now demands.

Indiana Solar FAQs

Does Indiana still have net metering?

Not for new customers. The five investor-owned utilities closed net metering to new applicants in July 2022; new systems earn Excess Distributed Generation credits instead, at 125% of avoided cost, roughly 3 to 5¢/kWh.

Systems installed before the cutoff keep retail netting until 2032 or 2047 depending on install date.

What does AES Indiana pay for exported solar?

AES Indiana’s EDG credit sits near 3.935¢/kWh, against retail power in the 14 to 17¢ range.

Rates differ at Duke, CenterPoint, I&M and NIPSCO and update over time, so make any quote name your utility’s current filed rate.

I am buying a house with solar panels in Indiana. What should I check?

The install date, in writing. Pre-2018 systems keep retail net metering until July 1, 2047, and 2018-2022 systems until July 1, 2032; the protection transfers with the property.

A post-2022 system earns EDG credits, which changes the value of the array meaningfully.

Is solar still worth it in Indiana without net metering?

For homes with real daytime usage, often yes: every self-consumed kilowatt-hour avoids 14 to 17¢ retail power, and install pricing in Indiana is moderate.

The math fails for low-usage homes and for any system sized far beyond what the household consumes.
