Indiana solar regulations.

For investor-owned utility customers, distinguish Excess Distributed Generation tariffs from preserved legacy net-metering service.

What to know in Indiana.

Which rules cover your project?

Confirm the actual tariff, export measurement and grandfathered status with your utility; cooperative and municipal arrangements need their own review.

Who provides electricity here?

Narrow possible delivery utilities by ZIP or confirm yours

Find the delivery utility on your electric bill first. A retail supplier or on-site solar seller may be a different company; your delivery utility handles the local grid connection.

Check your actual service address.

Official territory map links identify delivery utilities; confirm an address rather than assuming one provider serves an entire county.

Credits, rebates, and other opportunities.

Check the program’s scope before comparing savings: a tax exemption, equipment rebate, loan and electricity-export payment provide different benefits. Funding, utility territory, income, equipment and installation dates can limit eligibility. Amounts below are not added together or deducted from product prices.

OED says applications are open for whole-home efficiency upgrades through a unified rebate application.

Benefit
Eligible product and installation discounts through qualified contractors; award depends on household/project approval.
Who may qualify
Indiana household and project eligibility, program assessment and qualified-contractor requirements apply.
Before applying or buying
Apply through the official Indiana Energy Saver website before arranging work; the application is the only route to program rebates.

Indiana Department of Local Government Finance / County Auditor · Solar

Eligible solar, wind, geothermal or hydroelectric property can seek an assessed-value deduction using State Form 18865.

Benefit
Deduction depends on qualifying property and assessed value; it is not an installation cash rebate.
Who may qualify
Owner and qualifying device/system requirements; exclusions and filing dates on the current form apply.
Before applying or buying
File the certified statement with the County Auditor and confirm deadline and qualification before assuming the deduction.
Indiana — State Form 18865 Reviewed 2026-11-06

Energy Saver rebates require program eligibility and approved work. Renewable property-tax deductions are separate county-administered benefits. This is a curated starting list, not every local incentive or a guarantee of available funding.

Federal programs in every state

The federal rules below apply nationally. State-administered federal rebates still require the local program to be operating and your project to meet its conditions.

  • Residential Clean Energy Credit (25D)

    Closed / ended

    Not available for new property placed in service after December 31, 2025. Do not assume a federal 30% credit for a new 2026 solar, wind, geothermal or battery installation.

    IRS: Residential Clean Energy Credit

  • Energy Efficient Home Improvement Credit (25C)

    Closed / ended

    The federal home-efficiency credit, including qualifying heat-pump improvements, ended for property placed in service after December 31, 2025.

    IRS: Energy Efficient Home Improvement Credit

  • HOMES / High-Efficiency Electric Home Rebates

    Eligibility / funding conditions

    Federally funded home-energy rebates operate through participating local administrators. Check the state program’s launch, current funding, eligible measures and application requirements. This is not a blanket rooftop-solar rebate.

    DOE: Home Energy Rebates Program

  • Weatherization Assistance Program

    Eligibility / funding conditions

    Income-eligible households may receive approved home-weatherization services through local agencies. This is assistance delivered through a program, rather than an automatic reimbursement for equipment you buy.

Permits and electrical codes.

Indiana DHS links the currently effective code adoptions, Indiana amendments and local code-official directory. Proposed code updates should not be treated as adopted requirements.

Use the adoption authority linked below to check the effective date and amendments. The newest published NEC edition is not automatically the edition adopted for your project.

Before ordering equipment.

Two conversations. Keep their answers separate.

Your proposed system and location inform separate local-authority and serving-utility questions, which become dated project records.
A question map, not an approval sequence. Local permit/code questions and utility interconnection/export questions have different scopes; processes and reviewers vary by address and serving utility. Keep permit and interconnection records

Track permits and interconnection in a project

  1. Confirm the permit authority

    Ask the city, county, or state electrical office which building, electrical and fire-code editions and amendments apply to this address. Request the solar/ESS permit checklist and inspection sequence.

  2. Confirm the utility process

    Give the serving utility your proposed capacity, inverter model and operating mode. Ask which interconnection application, tariff, export limits, meter changes and written operating authorization apply.

  3. Document the exact equipment

    Collect model-specific certificates, installation manuals, a one-line diagram, site/roof plans, and the battery/inverter pairing if storage is proposed. Check them with the permit authority and utility before ordering.

For the general permitting and inspection process: DOE: Permitting and Inspection for Rooftop Solar .

UL, NEMA, and system acceptance.

Different evidence, different scope.

UL 1973 concerns battery scope, UL 9540 concerns an exact energy storage system, and UL 9540A is a test method; one does not automatically replace another.
Conceptual scope labels, not certification marks or product approvals. A battery listing or fire-test report alone does not establish acceptance of a complete installed system. Read the exact model/configuration records. Check exact certification and test scope

Check the exact model and approved system configuration. A UL 1973 battery listing or UL 9540A fire-test report does not, by itself, establish UL 9540 certification of a complete storage system.

Open the UL & NEMA reference

Scope and system-level certification: UL Solutions: Energy Storage System Testing and Certification .
