Indiana electricity rates have risen over time, though recent changes show why it helps to compare local prices with the national trend.
Indiana’s average residential electricity price climbed from 13.4 cents per kilowatt-hour in 2021 to 14.8 cents in 2024, despite a small dip from 14.9 cents in 2023. The U.S. average reached 16.5 cents in 2024.
In Indiana, a properly sized rooftop solar system can generate electricity at home and reduce the amount a household buys from its utility. The impact depends on system production, household use, and utility rules.
When you own a solar system, the upfront purchase can fix the cost of much of its expected electricity production. Future utility rate increases then affect a smaller share of your energy bill.
Price of Energy: Indiana vs National Average
Indiana Area Utility Providers
Indiana electricity prices vary by utility. The chart uses the latest available utility data, from 2023, and compares five providers with Indiana’s 14.90¢/kWh state average and the 16.0¢/kWh national average.
AES Indiana averaged 13.8¢/kWh and Duke Energy 14.3¢, below the state average. Indiana Michigan Power (I&M) was 16.1¢, NIPSCO 17.9¢, and CenterPoint Energy Indiana South 17.2¢—all above the state and national averages.
For Indiana homeowners, utility rates can influence solar’s potential value: a system that offsets electricity bought at a higher rate may provide greater bill savings. Actual results depend on household use, system output, and utility rules.

Indiana Solar Incentives
Indiana residents may find local and utility programs that affect solar costs. See the solar incentives in Indiana listed below.
Options depend on location and eligibility. Bloomington lists solar and battery rebates, and qualifying new systems may receive utility-specific credits for exported electricity. Other entries include loans and federal programs for eligible businesses, agricultural producers, and rural small businesses.
The federal 30% residential tax credit was eliminated by the 2025 Big Beautiful Bill. Local rebates and utility credits may remain worth checking; terms, eligibility, and funding vary.
| Incentive | Type | Description | Source |
|---|---|---|---|
| Bloomington Green Home Improvement Program (BGHIP) — Solar and Battery Rebates | Local Rebate | Bloomington’s published rebate table lists 20% of solar-panel project costs up to $5,000 and 25% of battery-system costs up to $5,000, subject to current program terms and available funding. | Learn More |
| Indiana Excess Distributed Generation (EDG) and Grandfathered Net Metering | Net Billing / Net Metering | Most new qualifying systems receive a utility-specific bill credit for exported electricity under EDG, while eligible older systems may retain net metering for a limited grandfathered period. | Learn More |
| PowerSave Indiana Solar and Battery Financing | Financing / Loan | PowerSave Indiana describes residential loans of $3,000–$50,000 for solar PV, batteries, and other eligible home improvements, with terms up to seven years and listed rates of 8.50%–8.75%. | |
| Federal Clean Electricity Investment Credit (§48E) — Eligible Business and Project Owners | Federal Business Tax Credit | Eligible business and project owners may qualify for a credit on qualifying clean-electricity property or energy-storage investment; this is not a homeowner tax credit for a personal residential installation. | Learn More |
| USDA Rural Energy for America Program (REAP) — Guaranteed Loans | Federal Loan Financing | Eligible agricultural producers and rural small businesses may apply for REAP guaranteed loans for qualifying renewable-energy projects, including solar; grant awards are paused, and a stand-alone battery is not eligible. | Learn More |
Bloomington’s BGHIP cost-estimate table lists a rebate of 20% of eligible solar-panel project costs, capped at $5,000, and 25% of eligible battery-system costs, also capped at $5,000. These are local incentives for eligible Bloomington homeowners, not statewide rebates.
The cited cost-estimate table is from 2025. Check the City’s current application, eligibility rules, and remaining funds before beginning work or relying on those amounts; the 2026 terms and availability should be confirmed directly with Bloomington.
For most qualifying systems with applications after June 30, 2022, Indiana investor-owned utilities use Excess Distributed Generation (EDG), not traditional 1:1 retail-rate net metering. Customers pay their normal rate for electricity drawn from the grid, while eligible excess electricity is credited at a utility-specific rate calculated under Indiana’s statutory formula. The credit is generally a bill credit, not a cash payment, and rates and tariff details vary by utility and can change.
EDG applies to qualifying customer-owned generation; this compensation applies only to systems you purchase and own. Because exported power is generally credited below the retail rate, using solar electricity at home as it is generated can be more valuable than exporting it. Get utility interconnection approval and check the current tariff before installation.
Eligible legacy systems may retain net metering under transition rules: qualifying systems installed before January 1, 2018, may remain until July 1, 2047, and qualifying systems installed from January 1, 2018 through June 30, 2022, may remain until July 1, 2032, subject to applicable statutory and utility requirements. Municipal utilities and electric cooperatives may have different compensation rules.
PowerSave Indiana offers financing rather than a rebate or grant. Its program information lists loans of $3,000 to $50,000 for solar PV and battery projects, with repayment terms of up to seven years and rates of 8.50%–8.75%.
Loan approval, eligible project costs, rates, and terms depend on the program’s current requirements and may change. Confirm current availability and the full loan terms with the program administrator before committing to a project.
Section 48E may provide eligible business and project owners a base credit of 6% of qualified investment in qualifying clean-electricity property or energy-storage technology. The rate may reach 30% when prevailing-wage and apprenticeship requirements are met; additional bonuses may apply in qualifying circumstances. This is a business/project-owner tax provision, not a federal homeowner credit for a personal household system.
Eligibility and the amount depend on the project, owner, tax rules, and construction and placed-in-service dates. For solar facilities, the law includes a termination rule for certain projects placed in service after December 31, 2027, depending on when construction begins; energy storage is treated separately under that provision. Consult the IRS guidance and a qualified tax professional for project-specific advice.
USDA REAP guaranteed loans may support eligible renewable-energy projects, including solar installations, for qualifying agricultural producers and rural small businesses. USDA’s current funding notice says guaranteed-loan applications continue to be accepted, while no further REAP grant awards will be made until revised regulations are in effect.
A renewable-energy system with storage, or a battery retrofit to an existing renewable-energy system, may be eligible under program rules; a stand-alone battery project is not eligible. This is business financing, not a residential homeowner rebate, and eligibility, loan terms, and application requirements should be confirmed with USDA before proceeding.

How to Choose a Solar Installer in Indiana
Verify the license
Indiana does not require a statewide solar-installer or general-contractor license. Plumbers are the only construction contractors licensed statewide; cities and counties may require licenses for electrical contractors and other contractors, and requirements vary. Ask each installer which company will do the electrical work, what local credentials apply, and how to verify them with your city or county. The Indiana Professional Licensing Agency offers a professional-license lookup, but it is not a substitute for checking local contractor requirements.
Look for certified installers
Ask whether the people designing and installing your system hold relevant NABCEP certifications, and whether the installer has certifications from the panel or inverter manufacturers it proposes. These credentials can indicate training or qualification for particular work or products; ask what each covers and who on your project holds it. They are useful points of comparison, not a guarantee of workmanship, system output, or a trouble-free project.
Compare quotes the same way
Request written quotes with the same assumptions, and compare the details rather than just the headline price. A typical reference point—not a recommended system size—is Palmetto’s median installed system size of 6.8 kW. Check whether each proposal is sized for your home and uses comparable assumptions.
- System and price: Compare system size in kW and total price per watt, plus panel and inverter brands and models.
- Production: Compare estimated annual production in kWh/year and ask what assumptions support the estimate.
- Coverage: Review panel product and performance warranties, inverter warranty, workmanship coverage, and coverage for roof penetrations. Note who backs each one and how to make a claim.
- Project responsibilities: Confirm who handles permits and utility interconnection, and what costs or tasks remain yours.
- Payment: Compare total cost as well as monthly payment, if shown. Check for any payment escalator and understand how it changes what you pay.
Permits, interconnection and your HOA
For one- and two-family homes, the local government or building official is the inspection authority. Permit requirements and procedures depend on the jurisdiction, so confirm building and electrical permits with your local building department. The homeowner or installer applies to the electric utility for interconnection. Indiana utilities include Duke Energy Indiana, LLC; AES Indiana; Northern Indiana Pub Serv Co; and Indiana Michigan Power Co. Ask your utility about its process; requirements for municipal and cooperative utilities should be confirmed directly with that utility.
Indiana has a limited HOA solar statute, not a universal rule invalidating every solar restriction. It generally applies to associations formed after June 30, 2009, with mandatory dues, or older associations that elected to be governed by the HOA article; the law also describes circumstances in which an HOA may prevent installation or use. Review your governing documents and confirm whether the statute applies to your association before signing.
Red flags
- Pressure to sign the same day or claims that an offer disappears unless you commit immediately.
- Unlicensed crews where local licensing is required, or out-of-state crews with no clear local contact or explanation of who will perform the work.
- Vague production estimates, or reluctance to explain the assumptions behind them.
- A large upfront deposit without clear written milestones, refund terms, and an explanation of what it covers.
- Promises of a federal homeowner tax credit for a purchase in 2026; homeowner credits ended December 31, 2025.
Frequently Asked Questions
Indiana has net metering for eligible older systems. For most qualifying systems applying to investor-owned utilities after June 30, 2022, excess solar receives credits under Excess Distributed Generation (EDG), not traditional 1:1 retail-rate net metering. Customers pay normal rates for grid electricity and receive utility-specific bill credits for exported power, usually below retail rates.
Systems installed before 2018 may retain net metering until July 1, 2047; systems installed Jan. 1, 2018–June 30, 2022, may retain it until July 1, 2032, subject to rules. Municipal utilities and co-ops may differ; verify the current tariff.
Yes, solar panels can increase a home’s value in Indiana when the homeowner owns the system outright. A Zillow study found that homes with solar panels sold for approximately 4.1% more.
That increase isn’t guaranteed; local buyer demand, system condition, and the home’s features all matter. Because you own the system, any added resale value belongs to you. Keep installation and equipment records to share with potential buyers.
In Indiana, a typical 8.91 kW solar panel system costs about $26,559 installed, or approximately $2.98 per watt, when purchased outright. Your actual price depends on system size, roof, and household electricity use.
The federal 30% residential solar tax credit was eliminated by the 2025 federal law change, so it is not included. See the Indiana solar cost calculator above for an estimate based on your home.
Solar can make sense in Indiana: the state averages about 4.6 peak sun hours per day, and residential electricity averaged 14.8¢/kWh in 2024. Actual production varies with location, roof direction, shade, and season.
A typical 8.91 kW purchased system is sized to generate about as much electricity as an average Indiana home uses and is estimated to reduce bills by about $131 per month. It may not eliminate the bill: fixed charges and utility-specific credits for excess power can leave a balance.
Solar panels in Indiana are low maintenance because they have no moving parts. They generally need only occasional visual checks for visible damage, debris, or anything blocking sunlight.
Rain often rinses away light dirt, though heavy buildup may need attention. Panels and inverters typically come with manufacturer warranties; coverage periods and terms vary by product.
Indiana homeowners may receive utility-specific Excess Distributed Generation (EDG) bill credits for surplus solar electricity; eligible older systems may retain net metering under transition rules. Bloomington’s Green Home Improvement Program lists rebates of 20% of eligible solar costs, up to $5,000, and 25% of eligible battery costs, up to $5,000. Check current eligibility and available funds.
PowerSave Indiana lists loans for solar and battery projects. The federal 30% residential clean-energy tax credit is no longer available after the 2025 federal law change.
