Savings
Key Takeaways
- A typical 6.8-kW system is estimated at $21,521, but savings and payback vary by home and electricity use.
- Indiana credits excess solar electricity at utility-specific rates, so using power at home can matter more than sending it to the grid.
- Solar production changes with the seasons: Indianapolis systems generally produce more in summer, while roof conditions, system size, and household use shape results.
Indianapolis Electricity Prices
For Indianapolis homeowners considering solar panel installation, Indiana’s electricity-price trend offers useful context.
Statewide, Indiana’s average electricity price rose from 13.4¢ per kWh in 2021 to 14.8¢ in 2024—about 10% overall—though it dipped slightly from 14.9¢ in 2023. These figures are state averages, not Indianapolis-specific rates.
In 2024, Indiana’s average was below the national average of 16.5¢ per kWh. A homeowner who buys a solar system can generate some electricity at home and may reduce utility purchases, depending on the system and household energy use.
Over the long term, an owned system can provide years of electricity production and help limit exposure to changing utility prices. Its overall value depends on the purchase cost, system output, roof, and how much electricity the household uses.
Price of Energy: Indiana vs National Average
Indianapolis Area Utility Providers
In Indianapolis, AES Indiana supplied electricity at 13.8¢ per kilowatt-hour in 2023, the latest utility data available. That was below Indiana’s 14.90¢ state average and the 16.0¢ national average for the same year.
These figures compare AES Indiana’s rate with broader state and national averages; they do not explain the causes of the differences. Electricity prices vary by utility and service area, so the averages may not match every Indianapolis household’s bill.
For Indianapolis homeowners considering solar, the comparison offers a useful baseline, not a savings estimate. A purchased system can generate electricity at home and offset some utility purchases, depending on household use and solar production.

Indiana Solar Incentives
Indiana state and local programs may help offset solar costs, but eligibility varies by location and utility. See the solar incentives in Indiana table for details.
New qualifying systems receive utility-specific EDG credits for exported power; older eligible systems may retain net metering for a limited period. Bloomington’s rebates cover 20% of solar and 25% of battery costs, each capped at $5,000, for eligible local projects.
PowerSave loans: $3,000–$50,000, up to seven years, at 8.50%–8.75%. §48E business/project-owner credits aren’t for personal homes; the 30% federal residential credit was eliminated by the Big Beautiful Bill.
| Incentive | Type | Description | Source |
|---|---|---|---|
| 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 |
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.

How to Choose a Solar Installer in Indianapolis
Verify the license
Indiana does not require a statewide solar-installer or general-contractor license. Plumbers are the only construction contractors licensed statewide; licensing for electrical contractors and other contractors may be set locally and varies by city or county. Ask the installer which company and crew will do the electrical and construction work, and confirm any required credentials with your local government. The Indiana Professional Licensing Agency lookup checks professional licenses; it is not a statewide solar-contractor registry. Ask your city or county building department what local contractor licensing applies.
Look for certified installers
Ask whether the people who will design and install your system hold relevant NABCEP certifications, and what each credential covers. Certification can be a useful indication of documented training and qualifications, but it does not replace checking references, the proposed design, insurance, or local requirements. Ask about manufacturer certifications for the specific panels and inverters in your quote, too; these can indicate product-specific training or authorization. Confirm what credentials are held by the actual installation crew, not only the salesperson.
Compare quotes the same way
Request written proposals with matching assumptions. A lower total may reflect a smaller system, different equipment, or a different scope. Compare:
- System size in kilowatts (kW), and price per watt, calculated using the same price basis.
- Panel and inverter brands and models, plus the estimated annual production in kilowatt-hours (kWh/year) and the assumptions behind it.
- Warranty terms and duration for panel product and performance, inverter, installer workmanship, and roof penetrations. Ask who handles a claim.
- Who obtains building and electrical permits and submits the utility interconnection application.
- Total cost and payment schedule, or monthly payment and any escalator. Compare the full terms, not just the first payment.
For context, Palmetto reports a median installed system size of 6.8 kW and about 83 days from signing to installation. Those are Palmetto-specific figures, not a universal target; ask each installer for its expected timeline.
Permits, interconnection and your HOA
For one- and two-family homes, the local government or building official is the inspection authority. Permit steps can vary by jurisdiction, so confirm building and electrical permit requirements with your local building department. You or your installer applies to your electric utility for interconnection. Depending on your service area, the utility may be Duke Energy Indiana, LLC, AES Indiana, Northern Indiana Public Serv Co, or Indiana Michigan Power Co. Ask the utility about its requirements; applicable interconnection standards vary by utility type.
Indiana has a limited HOA solar statute, not a rule that invalidates every HOA restriction. Its coverage depends on the association and circumstances; some associations may prevent installation or use. Review your governing documents and check whether the statute applies before relying on it. See Indiana Code §§ 32-25.5-3.5-4 and 32-25.5-3.5-5; the separate solar-easement law is not a general limit on HOA bans.
Red flags
- Pressure to sign the same day or accept terms before you can review the proposal.
- Unlicensed or out-of-state crews without a clear explanation of who is responsible and how local requirements are met.
- A vague production estimate with no annual kWh figure or explanation of its assumptions.
- A large upfront deposit without a clear written payment schedule and scope of work.
- Promises that you can claim federal homeowner tax credits for a 2026 purchase; homeowner credits ended December 31, 2025.
Palmetto is one installer you can include when comparing written quotes and terms.
Frequently Asked Questions
Indianapolis generally does not offer traditional 1:1 net metering for new solar customers. Under Indiana’s Excess Distributed Generation (EDG) rules, AES Indiana customers receive bill credits for excess electricity sent to the grid. The credit rate is utility-specific and may be lower than the retail price of electricity.
Eligible older systems may retain net metering under state transition rules. Check AES Indiana’s current tariff and interconnection requirements to confirm which compensation rules apply to your home.
Yes, solar panels can increase a home’s value in Indianapolis when the homeowner owns the system outright. A Zillow study found homes with solar panels sold for approximately 4.1% more, though the actual effect depends on the home, system, and local market.
Because you own the panels, any added resale value belongs to you. Buyers may also consider the system’s expected production and potential to reduce utility purchases; Indianapolis solar output varies by season and household use.
Buying a solar system outright in Indianapolis typically costs about $21,521 installed for a 6.8-kW system, or approximately $3.16 per watt. Estimates in the article range from $16,912 for a smaller system to $27,506 for a larger one.
The federal 30% residential solar tax credit was eliminated by the 2025 federal law change and is not included. See the solar cost calculator above for a more specific estimate based on home size.
Solar can be financially worthwhile in Indianapolis when the system’s long-term bill savings exceed its purchase cost. The article estimates a typical 6.8-kW system at $21,521, with a 14.3-year payback and about $44,070 in savings over 25 years; actual results depend on your roof, energy use, system output, and utility rates.
When you own the panels, you keep the savings and applicable utility credits from every kWh they produce. AES Indiana’s excess-generation credits may be worth less than the retail rate, so using solar power at home can improve the economics.
Solar panels in Indianapolis are low maintenance. They have no moving parts, so they generally do not need regular servicing.
Occasionally check from the ground for visible damage or heavy debris, especially after severe weather. Panel and inverter manufacturer warranties may cover eligible defects for specified periods; terms vary by product.
Indianapolis homeowners with qualifying new solar systems generally receive AES Indiana’s utility-specific Excess Distributed Generation (EDG) bill credits for electricity sent to the grid; eligible older systems may retain net metering under transition rules. Indiana’s PowerSave program lists solar and battery loans of $3,000–$50,000, with terms up to seven years and rates of 8.50%–8.75%.
Bloomington offers eligible local projects rebates covering 20% of solar and 25% of battery costs, capped at $5,000 each; these are not Indianapolis rebates. The federal 30% residential tax credit is no longer available after the 2025 law change.
