Why solar in South Bend

If you are buying a South Bend house that already has solar, one question is worth asking before you agree a price: when was the system installed. Indiana grandfathered existing solar customers onto full net metering on a schedule, and a grandfathered array is worth substantially more than a new one. A system installed before 2018 keeps net metering until July 1, 2047. It will not be obvious from the roof.

Two dates that decide what an array is worth

When Senate Enrolled Act 309 closed net metering, it grandfathered existing customers rather than moving everyone at once, and it did so on a schedule tied to installation date.

A system installed before 2018 receives full net metering until July 1, 2047. That is a long remaining term and it is worth a great deal.

A system installed between the start of 2018 and the close of net metering for new customers receives full net metering until July 1, 2032.

Anything installed after the programme closed receives the Excess Distributed Generation credit instead, roughly 70 to 80 percent below the retail rate. Three tiers, decided entirely by a date.

What to establish before you agree a price

Ask the seller for the installation date and the interconnection date, and ask to see documentation rather than accepting a recollection. Those dates place the system in one of the three tiers.

Ask which programme the account is actually on today, and get that confirmed by the utility rather than by the seller. A tier is only worth something if the account is genuinely on it.

Ask whether the grandfathered status transfers to a new owner, what has to be done to effect that, and by when. An arrangement that does not survive the sale is worth nothing to you.

Then price accordingly. A pre-2018 array with twenty-one years of full net metering remaining is a materially different asset from an identical array installed in 2024.

The rest of the checks on an existing system

Ask for production history rather than a production estimate. An installed system has real data, and real data is worth far more than a model.

Ask for the equipment make and model and what warranty remains on the panels, the inverter and the workmanship. Inverters typically have shorter lives than panels, and a pre-2018 system may be approaching an inverter replacement.

Ask about the roof underneath. A system on a roof near the end of its life implies a removal and reinstallation cost that belongs in your purchase arithmetic.

Ask whether the system is owned outright, financed, or on a lease or power purchase agreement. Those are entirely different things to inherit, and only the first is straightforwardly an asset.

Building the number from what Indiana still offers

For a new system, the 30 percent federal Residential Clean Energy Credit under Section 25D expired for property placed in service after December 31, 2025, and Indiana has no state income tax credit for solar.

Section 48E survives at 30 percent for third-party owners under leases and power purchase agreements.

A new system receives the Excess Distributed Generation credit at the prior year average wholesale cost plus 25 percent, under whichever netting method your utility applies, plus the sales and property tax exemptions.

For an existing system, start with the installation date and whether grandfathered status transfers. That single fact changes what the array is worth more than anything else about it.

Incentives & rebates

Net metering: Net metering closed; EDG credit at 125% of wholesale

Indiana closed net metering to new solar customers under Senate Enrolled Act 309, no later than July 1, 2022. New residential systems instead receive the Excess Distributed Generation credit, which the Indiana Utility Regulatory Commission sets at the average wholesale cost of electricity from the prior year plus 25 percent. That has produced a credit roughly 70 to 80 percent below the retail rate, so an exported kilowatt hour is worth a small fraction of one you consume yourself. A second change compounds the first. The Indiana Supreme Court held that a utility may measure excess generation instantaneously rather than netting across a billing period, on the reasoning that the statute does not direct utilities on how often the measurement must be made. Under instantaneous netting a household pays the full retail rate for everything it draws from the grid at any moment while everything it sends to the grid earns only the Excess Distributed Generation rate, with no monthly offset in between. The practical consequences are large. A system sized to annual consumption will export a great deal of its midday output at the low rate, so a smaller system matched to daytime load frequently returns better. Shifting flexible loads into daylight converts low-value exports into full-value offsets at no cost, and storage carries more weight here than the national conversation suggests. Existing customers were grandfathered: systems installed before 2018 keep full net metering until July 1, 2047, and those installed between the start of 2018 and the close of the programme until July 1, 2032.

Frequently asked questions

Are older Indiana solar systems still on net metering?

Many are. A system installed before 2018 keeps full net metering until July 1, 2047, and one installed between the start of 2018 and the close of the programme keeps it until July 1, 2032. Anything later receives the Excess Distributed Generation credit.

I am buying a house with solar. What should I ask?

The installation and interconnection dates with documentation, which programme the account is on today confirmed by the utility, and whether grandfathered status transfers to a new owner, what is required and by when.

How much difference does the tier make?

A large one. Full net metering credits exports at the retail rate; the Excess Distributed Generation credit runs roughly 70 to 80 percent below it. A pre-2018 array with decades of net metering left is a materially different asset from an identical new one.

What else should I check on an existing array?

Production history rather than an estimate, equipment models and remaining warranties including the inverter, the condition of the roof underneath, and whether the system is owned outright, financed, or on a lease or power purchase agreement.
