Is Solar Worth Indiana? Save $8,000+ with 2026 Tax Exemption

Indiana electricity bills have gone up a lot. The average rate is now about 17¢ per kWh in 2026. That is 10% higher than it was in 2021. This makes the question of Is solar worth Indiana very important for homeowners right now. By the end of this page, you will know what solar costs in Indiana, what savings you can expect, and whether it makes sense for your home.

Indiana is not the sunniest state. But it gets 4.3 to 4.6 peak sun hours per day on average. That is enough to make solar work well for many Indiana homes. The state also has a 7% sales tax break on solar equipment. And it protects you from higher property taxes after you install solar. These two benefits are real and worth knowing about before you make any decision.

Key Takeaways

• Indiana’s electricity rate hit about 17¢/kWh in 2026, up over 10% since 2021.
• A typical Indiana solar system costs $24,000–$27,000 before the 7% sales tax exemption.
• Indiana’s sales tax exemption saves you $1,700–$1,900 upfront on a standard system.
• Indiana’s five big utilities replaced true net metering with the lower-rate EDG program in 2022.

How Much Do Solar Panels Cost in Indiana?

Most Indiana homes need a system between 8 and 9.5 kilowatts (kW). That size covers most of a typical home’s monthly electricity use. The cost for that system runs between $24,000 and $27,000 before any savings apply. That price covers the panels, installation, permits, and the inspection your utility needs before turning the system on.

Your final price depends on a few things. Roof type matters. System size matters. Your utility company matters too. A home in Indianapolis on AES Indiana will have different needs than a home in Bloomington on Duke Energy Indiana. Your installer will check your roof direction, any shading from trees, and your monthly usage before giving you a quote. A south-facing roof with no shade will always give you the best results and the fastest payback.

To see how Indiana prices compare to the rest of the country, solar panel cost for U.S. homes breaks it all down clearly.

What Does a Real Indiana Homeowner Pay?

Here is a simple real example. A homeowner in Indianapolis uses 876 kWh per month. They pay AES Indiana about 14¢ per kWh. That adds up to about $1,470 per year on electricity. An 8.5 kW solar system costs $25,000 before the tax break. Indiana’s 7% sales tax exemption saves $1,750 right away. So the real out-of-pocket cost drops to about $23,250.

Over 25 years, that system could produce electricity worth $35,000 to $40,000. That depends on how much the rates keep rising. The payback period in Indiana is usually 13 to 15 years. That is longer than in states with higher electric rates. But panels last 25 to 30 years. So you still get 10 to 15 years of very cheap electricity after you break even. I think that is a solid deal for most Indiana homeowners.

Indiana Solar Incentives That Still Matter in 2026

Indiana does not have a state income tax credit for solar. But two strong benefits are still in place. They lower your real cost in ways most homeowners overlook.

Sales Tax Exemption — 7%. Indiana does not charge sales tax on solar equipment. On a $25,000 system, that saves you $1,750 right at purchase. You never even pay that money. It is removed from your bill before you sign anything.

Property Tax Exemption. Solar panels add real value to your home. A typical system adds $10,000 to $15,000 to your home’s market value. Indiana law says that added value cannot raise your property tax bill. You get the home equity benefit with no annual tax penalty attached to it.

NIPSCO customers have one more option. NIPSCO runs a feed-in tariff program. It pays $0.13 to $0.17 per kWh for systems between 5 kW and 10 kW. Spots are limited and fill up fast. Check if enrollment is open before counting on this benefit in your budget. You can check all active Indiana solar programs on the official DSIRE database at dsire.org. It lists every state-level solar policy in one place.

Indiana Net Metering: What Changed in 2022

This part is very important. Most Indiana solar articles skip it or get it wrong. In 2022, Indiana’s five biggest utilities stopped offering true net metering to new solar customers. The five utilities are AES Indiana, CenterPoint, Duke Energy Indiana, Indiana Michigan Power, and NIPSCO. If you install solar today with any of them, you go on the EDG program instead.

EDG stands for Excess Distributed Generation. Under EDG, when your panels make more power than your home uses, that extra power goes to the grid. Your utility gives you a credit for it. But the credit rate is much lower than what you pay for electricity. AES Indiana pays about 3.9¢ per kWh under EDG. But you pay about 14¢ per kWh when you buy electricity. That is a big gap.

What does this mean for your system? Size it to cover your own home’s usage. Do not try to make extra power to sell back. Selling at 3.9¢ when you paid $25,000 for the system does not make sense. Focus on using the power your panels make for yourself. Some small rural co-ops and local utilities still offer better credit rates. Always check with your specific utility before assuming EDG applies to you.

How Solar Performs in Five Indiana Cities

Indiana is a long state. It runs about 300 miles from north to south. Cities in the south get more sun than cities in the north. That difference is real and affects how much electricity your panels make each year. Here is how five major Indiana cities compare.

These savings use 876 kWh per month, a 17¢/kWh rate, and an 8.5 kW system as the base. Your real savings will depend on your roof, your shading, and your exact utility rate. Evansville has the best case for solar in the state. It has the most sun and some of the highest utility rates. South Bend has the toughest case. Less sun and more cloudy winter days mean lower yearly output.

Is Solar Worth It in Indiana? The Real Answer

Solar works well for most Indiana homeowners who own their home, have a south-facing roof, and pay more than $130 a month on electricity. The payback takes longer than in sunnier states. But Indiana rates keep going up. They rose over 10% between 2021 and 2026. Every year rates go up, your solar system saves you more. That trend works in your favor the longer you own the panels.

One Real Limitation You Should Know

Indiana winters are hard on solar output. In December and January, Indianapolis averages only about 2.8 peak sun hours per day. Your panels slow way down in winter. You will pull some electricity from the grid during the cold months. A good installer will size your system to account for this. But you should not expect a $0 electric bill in January or February.

The EDG policy is the other real limitation. Before 2022, Indiana homeowners could earn full retail credit for every kilowatt they sent to the grid. That option is gone with the five big utilities. The numbers still work in Indiana, but only if your savings estimate is based on EDG rates, not the old net metering rules. Any quote built on the old system will be too optimistic.

“My Bill Is Not That High”: Does Solar Still Make Sense?

This is the question I hear most from Indiana homeowners. Indiana rates are below the national average. So solar does not feel as urgent as it does for someone in California paying 28¢/kWh. That is a fair point. But the math still holds up when you look at the full picture.

A home using 876 kWh per month at 17¢/kWh spends about $1,790 per year on electricity. Over 25 years at today’s rate, that is $44,750 total. And rates are still going up. A solar system with a 14-year payback still gives you 11 years of very cheap electricity after that. That is real money back in your budget.

Solar also raises the value of your home. The Solar Energy Industries Association data shows solar adds about $15,000 to the average home value. Indiana’s property tax exemption means that added value does not raise your annual tax bill. If you plan to sell your home in the next 10 years, the value increase alone can cover much of your system cost. For a state-by-state look at how solar affects home value, do solar panels increase home value covers the real data.

How Indiana Compares to Nearby States

Indiana sits in the middle of the pack for solar. It is not as strong as Massachusetts, where rates are 22¢/kWh. It is stronger than Kentucky, where low TVA rates make solar harder to justify. Ohio is the closest comparison, similar sun hours, similar rates, similar payback timeline.

Within Indiana, the difference between north and south is big. Evansville gets about 20% more peak sun hours per year than South Bend. If you live in southern Indiana, your solar case is noticeably stronger. If you live in the north near South Bend or Fort Wayne, solar still works, but winter output will be lower and your payback will take a bit longer.

For a useful side-by-side comparison with a neighbouring state, why solar panels are worth it in Ohio gives you a direct reference point.

Final Thoughts

Is solar worth Indiana? is a question with a clear answer for the right home. Rising utility rates, a 7% sales tax break, and zero property tax impact create a real long-term case. The payback is not the fastest in the country. But for a home with a good roof and a bill above $130 a month, the 25-year numbers work. Evansville and Bloomington have the best results. South Bend and Fort Wayne work too, just with honest winter expectations.

Your best first step is simple. Pull your last 12 months of utility bills. Add them up. That total is your baseline. Then check whether your utility uses the EDG program or something better. Those two facts will tell you more about your personal solar case than any website calculator ever could. 

Frequently Asked Questions

Do Indiana homeowners qualify for the federal solar tax credit?

Yes, Indiana homeowners who purchase and own their solar system qualify for the 30% federal Investment Tax Credit. The credit applies to your federal tax liability and is available statewide regardless of which utility serves your home.

What is the average payback period for solar in Indiana?

Most Indiana homeowners see an estimated payback period between 11 and 17 years, depending on their location, system size, and electricity usage patterns. Southern Indiana homes in cities like Evansville generally reach payback slightly faster than northern cities like South Bend due to marginally higher sun hours.

Does Indiana offer any state solar incentive programs?

Indiana doesn’t currently have a large state rebate or tax credit program beyond the federal ITC. Some utilities have offered small programs historically, but the main financial benefits come from the federal tax credit and Indiana’s statewide retail-rate net metering policy.

How does net metering work for Indiana homeowners?

Indiana has statewide net metering that requires utilities to credit excess solar production at the retail electricity rate. This is a genuine advantage compared to states with reduced export rates, and it meaningfully improves your savings timeline over the life of your system.

Is solar worth it in northern Indiana cities like South Bend and Fort Wayne?

Solar works in northern Indiana, though sun hours are slightly lower than in southern Indiana due to Lake Michigan’s influence and more cloud cover. Payback periods tend to be longer, but the federal tax credit and net metering still support reasonable economics for many homes.

How does Indiana’s winter weather affect solar panel performance?

Snow and persistent winter cloud cover significantly reduce production from November through February. Snow on panels stops production until it melts or slides off, and gray winter days deliver minimal output even without snow coverage. Strong spring and summer production typically balances annual totals.
