** What's new for 2019 **

When we last checked in with the Hoosier State, the future did not seem all that bright for solar power here. We’re happy to report that the legislature has started to make progress. The implementation of an RPS — even an optional RPS — is a solid start toward strong solar policy. There is, however, a great deal of work left to be done, and legislators are missing easy opportunities for big gains for Indiana solar panels. Let’s take a look at where solar policy here is strong, and where it still needs to be improved.

Questions? Our network of solar experts are on call to assist you. Simply sign up for personalized assistance on our special solar deals page. You can get discounted on-grid pricing as low as $3,500/kW! This is paired with the Indiana solar incentives you see below.

The Solar Strategy section is focused on the 3 ways of paying for solar in Indiana, so you can decide which is best for you. We've created a tool that asks you a few questions and recommends whether you should pursue a solar lease, loan, or outright purchase. Then, we provide detailed analysis of how each works.

The Policy Information section contains all our latest research on the rules set by lawmakers and the Public Utilities Commission, which determine how easy it is to go solar in Indiana. These policies and rules govern everything from renewable energy mandates to interconnection, and have a huge effect on the viability of solar.

Finally, the Solar Incentives section includes information about money-back rebates and grants, tax credits, and tax exemptions for going solar in Indiana.

Your Solar Strategy in Indiana

Figuring out the best way to go solar in Indiana can be a little daunting. From loans and leases to power-purchase agreements, there are a lot of options out there. To help you pick the one that might be best, we've created the handy decision tool below.

We'll ask you a few simple questions about you and your home. Once you're done, we'll recommend a good option. Further down this page, we provide cost estimates and example return-on-investment calculations for all the various options:

How to pay for solar panels in Indiana

The chart above shows the 25-year returns for an investment in solar whether you choose to purchase a system with cash or pay over time with a loan. Since economic conditions in Indiana don't allow for homeowners to get solar through a third-party agreement like a lease or Power Purchase Agreement, we included two different sizes of solar loans—one for people with a lot of equity, and one for people with just a little.

As you can see, the purchase option leads to pretty high dollar-amount returns over time, but it also requires a big up-front investment. Even if you take a solar loan or home equity line of credit (HELOC), your payments over 15 years will be way more than your savings, and you'll barely come out ahead in the end.

Read on to find out more about each option.

How much can you save with solar?

Find out

Option 1: Paying cash for solar

Look, any way you slice it, going solar in Indiana is tough. Paying up front for panels requires a lot of money and a lot of patience. You'll get the 30% federal solar tax credit, but electricity savings will be small.

Net Present Value: -$3,295

Net Present Value (NPV) measures how good of an investment something is, compared to the best alternative. We use a 6% return to evaluate all solar investments, and Indiana's -$3,295 NPV on a 5-kW solar system means you'd be way better off investing your money in stocks over 25 years than in Indiana solar. But check out what happens to NPV if you buy the same system with a loan that you can pay back over time. It doesn't solve all the problems, but it does make the financial picture a little rosier.

Here’s how the numbers pencil out for an Indiana solar purchase with a 5-kW rooftop solar system:

  • Installing a typical 5kW solar system should start at about $21,250. Don’t worry – even without state incentives, you can still knock a big chunk off the price right off the bat.
  • Since the Feds calculate their incentive based on actual out of pocket costs, no state incentives means a bigger federal solar tax credit. Subtract $6,375 (30% of $21,250) for a new price of $14,875.
  • Don't forget your first year’s energy savings, which we estimate to be about $643. That brings your cost after the first year to $14,232.
  • By the time your system pays itself back in year 18, you’ll be seeing over $1,000 per year in savings until the end of your system’s life.
  • When all is said and done, our 25-year estimate shows a total net profit of $7,907, with an internal rate of return of 3.5%. That isn't so bad... unless you compare it to an alternative investment in the stock market.
  • In addition to that cash, you’ve created some green for the earth as well by not using electricity from fossil-fuels. In fact, the energy you’re not using has the carbon equivalent of planting 97 trees a year, every year your solar power system is humming.
Keep in mind, the numbers above are based on an average home in Indiana. If you're ready for a custom quote for a solar panel system, our network of experts are on call to assist you. Simply sign up for personalized assistance on our special solar deals page.

Option 2: Using a loan to pay for solar

Usually this is the place where we tell you that taking a loan to pay for solar is a great idea. That's because it's usually true. High electricity prices around the country make a solar panel system into an income-generating asset.

The returns in Indiana are still pretty good, but they miss the excellence of the best solar states by a wide margin. The state enjoys some of the lowest electricity prices in the nation, and that means savings are pretty slim.

Still, as you can see from the chart above, you'll start out with a big windfall, because even though you're not putting any money down, you get the Federal 30% tax credit for the whole installed cost of your system. Then, over the 15-year life of your loan, you'll be spending more than you're saving in electricity costs, essentially investing a total of about $10,000 until you pay the loan off.

But from there, it's up-up-up! After your loan is paid off, you'll be saving more than $1,000 per year in electricity costs from your fully-owned solar panels. But you'll end up only $864 to the good after 25 years, which, we've gotta admit, is pretty crappy.

Net Present Value: -$1,567

Net Present Value (NPV) measures how good of an investment something is, compared to the best alternative. We use a 6% return to evaluate all solar investments, and Indiana's-$1,567 NPV on a 5-kW solar system with a loan means you'd be that much better off investing your money in stocks over 25 years than in Indiana solar. Only go solar in Indiana if the environmental benefits are worth that much to you.

Here’s how the numbers pencil out for an Indiana solar purchase with a solar loan:

  • Installing a typical 5-kW solar system should start at about $21,250. That's how big your loan will need to be to cover it.
  • The electricity you'll save in the first year of operation would have cost $644, but your loan payments will total $1,886, for a difference of $1,242, or about $104 per month.
  • That's not so bad when you consider your tax savings for the year will be $6,375! You'll come out over $5,100 ahead in year 1, which should help ease the burden of loan payments for a few years, at least.
  • When your loan’s paid off in year 15, you’ll start see $1,000 or more per year in savings until the end of your system’s life.
  • For our 25-year estimate, you'll break even in year 25, to the tune of $864. The good news is your system will likely keep working for long into the future, but we stop at 25 years, which is the warranty term for the panels.
  • And the future is going to look a little brighter, since your system will mean green for the environment. It'll be like planting 97 trees every year!
Keep in mind, the numbers above are based on an average home in Indiana. If you're ready for a custom quote for a solar loan, our network of experts are on call to assist you. Simply sign up for personalized assistance on our special solar deals page.

Option 3: Buying the electricity, not the panels with a Power Purchase Agreement (PPA)

Indiana does not offer solar Power Purchase Agreements or leases. Perhaps it would be a good idea to contact a solar advocacy organization and ask them to fight for solar in your state!

Indiana Solar Policy Information

Ever wonder why solar seems to be everywhere in some states, but not in others? We did too.

State legislatures and public utilities commissions can enact rules to make solar power accessible for everyone. Favorable rules explain why some of the cloudiest states—New York, New Jersey, and Connecticut, are doing so well with solar, and yet some of those with the most natural solar resources—like Alabama, Mississippi, and Georgia—are doing so poorly.

Below is important information about the public policy, rules, and economic reasons that affect your ability to go solar here in Indiana:


10% by 2025 (voluntary)

Grade: D

Indiana's Renewable Portfolio Standard grade

A Renewables Portfolio Standard (“RPS”) requires utilities in the state to eventually source at least a certain percentage of their electricity from clean, renewable sources like solar panels.

Indiana unfortunately lacks a true RPS, but legislators have recently started at least moving in the right direction. In May 2011, Indiana passed the Comprehensive Hoosier Option to Incentivize Cleaner Energy (“CHOICE”) program. CHOICE sets a voluntary goal of 10% clean energy by 2025 (based on 2010 production levels). Utilities that elect to participate in CHOICE are eligible to receive incentives from the state to help pay for the cost of CHOICE-compliant projects like Indiana solar panels. The program could be even better if it actually, y’know… REQUIRED utilities to participate—something most other states have done.

The program launched in January 2012. No reports on utilities opting into the program or their progress have been reported as of yet. Utilities that do opt in are expected to meet the CHOICE goals in 3 stages: an average of 4% qualifying clean energy between 2013 and 2018; 7% between 2019 and 2024; and finally 10% by 2025.

A mandatory Indiana RPS would be critical to strong renewable energy policy. Utility companies aren't really all that gung-ho about you producing your own power. After all, it costs them money when you use less of their electricity. They also don’t naturally want to give you big payments for energy you're feeding back into the grid. The main reason the utilities are aiding your transition to lower electric bills and offering you incentives to put solar on your roof is because the state forces them to. If the utilities don't hit their RPS numbers, they have to pay large fees back to the state.

What's an RPS? Your state legislature paves the way for strong solar energy incentives to flourish by setting standards for renewable energy generation within their territories. Those standards are called the state’s renewable portfolio standard (RPS). If utility companies do not meet these standards, they must pay alternative compliance fees directly to the state. Many utilities then determine the best ways to source their energy from renewable sources that are less expensive than this fee.

An RPS is a mandate that says "Hey utilities! Y'all now have to make a certain percentage of your electricity from renewable sources. If not, you'll have to pay us huge fines." The consequences are good, because utilities usually try to meet these RPS standards by creating solar power incentives for you, the homeowner. Read more about Renewable Portfolio Standards.

RPS solar carve out


Grade: F

Indiana's Solar Carve-out grade

The best states for solar mandate that a certain percentage of the RPS comes directly from solar energy. Without a mandatory RPS in Indiana, this is another area that falls short. If an RPS contains specific carve-outs for clean and efficient technologies like solar panels, or mandates for the environmentally necessary increases in distributed generation, you see even stronger incentives for residential solar power.

What's a solar set aside? A solar set aside guarantees a specific portion of the overall renewable energy mix generated comes from the sun. For those states with progressive standards, high alternative compliance payments, and clear solar carve outs, the faster those areas become ripe for solar.

Some states have higher alternative compliance fees than others, and some states have more progressive alternative energy standards and deadlines than others do.

For instance, New Jersey has an overall RPS of 22.5% by the year 2021. That requires local utilities to source 22.5% of their energy mix from renewable sources by the year 2021. Pretty good. However, New Jersey also has a specific solar set aside of 4.1% by 2028. That’s the type of firm commitment which really gets the industry rolling forward. No wonder why New Jersey is one of the hottest solar markets right now!

Indiana Electricity Prices


Grade: C

Indiana's Electricity cost grade

Indiana pays an average of 12 cents/kWh of electricity; about a penny-and-a-half less than the national average. That’s cheap! Too cheap.

Why is energy still so cheap? Only because most of our electricity still comes from burning millions of tons of fossil fuels. The cost of those fossil fuels in dollars and cents may be low (for now), but the environmental costs are astronomically high. New regulations on carbon emissions and dwindling supplies will likely drive the cost up over the next few decades. But while everyone else is paying through the nose for the fuels of the past, you’ll be rocking that sweet, shiny solar power system on your roof, and making money! Just remember to thank us.

Why are electricity prices so important? Because that is what solar power is directly competing against. The cost to produce power with solar is relatively constant (of course how much sun hits your area has an effect), so if you are paying $0.40 per watt for power, then you make FOUR TIMES AS MUCH as the guy or girl paying $0.10 per watt electricity.

The caveat here is that if the $0.10 per watt person has a HUGE rebate, they may be better off than the $0.40 per watt person. Because of that, states without any renewable standards tend to be heavily reliant on cheap coal for electricity, and also have very low electricity prices. When electricity prices are artificially low, that hinders the ability of solar energy to achieve meaningful payback in the state.

Indiana Net Metering


Grade: B

Indiana's Net Metering grade

Net Metering requires your utility to monitor how much energy your solar power system produces and how much energy you actually consume, and make sure you get credit for the surplus.

Indiana net metering standards call for surplus energy production to be applied as a credit on your next monthly bill. Credits can be carried over indefinitely, but there are no provisions forcing the utility to cut you a check if you continually run a surplus.

Overall we gave net metering in Indiana a B because of system size caps that may prevent larger customers from meeting all of their on-site energy needs, and aggregate circuit capacity limits that may prevent everyone who wants to take advantage of net metering from doing so. That said, net metering is fairly strong for residential customers, and with 40% of current net metering capacity reserved for residential use, you shouldn’t have any problems getting into the program.

What is net metering? Net metering is the billing arrangement where you can sell excess electricity back to your utility for equal the amount you are charged to consume it. The more customer friendly net metering policies, the higher the grade.

The grade here specifically reflects individual solar system capacity, caps on program capacity limits, restrictions on “rollover” of kWh from one month to the next (yep just like cell phone minutes), metering issues (like charges for new meters), Renewable Energy Credit (REC) ownership, eligible customers and technology (the more renewables the better), being able to aggregate meters across the property for net metering, and safe harbor provisions to protect customers from solar tariff changes.

Indiana Interconnection Rules


Grade: B

Indiana's Interconnection Standards grade

Interconnection standards are strong in Indiana as well. Systems under 10 kW (i.e. most residential systems) fall into Level 1 of the tiered system. Level 1 systems do not pay any fees for application or interconnection review, and utilities may not specify any additional requirements for you to get onto the grid. The only thing we’d like to see changed for Level 1 standards is a prohibition on the requirement of a redundant external disconnect switch. Currently that requirement is at the utility’s discretion.

Interconnection rules are a little technical, but they basically allow you to “plug in” to the electric grid with solar panels on your roof. The more complex, out of date, or nonsensical the state rules are for plugging into the grid, the lower the grade.

Specifically, the grade reflects what technologies are eligible, individual system capacity, removing interconnection process complexity for smaller systems, interconnection timelines and charges, engineering charges, prohibiting the requirement of unnecessary external disconnects, certification, spot interconnection vs. wide area interconnection, technical screens, friendliness of legalese, insurance requirements, dispute resolution, and rule coverage.

Solar Incentives in Indiana

Next to high electricity prices and net metering, solar incentives have traditionally been the most important factor for whether home solar power makes financial sense in a state. In the past, some states with otherwise lousy policy had tremendous incentives that drove down the up-front cost of going solar so much that homeowners could save oodles of money even without net metering or a good RPS.

These days, the big incentive most people can get is the Federal Solar Tax Credit that earns you 30% of your costs back after just 1 year. State incentives play less of a role than in the past, but some really good ones are still out there, ready to help homeowners go solar and save money before you know it.

Let's see how Indiana measures up:

Indiana Solar Power Rebates


Grade: F

Indiana's Solar Rebates grade

Indiana solar panel rebates are extremely limited as well. In fact, in the entire state only IP&L offers a rebate on the installation of a residential solar power system, and the rebate program is set to expire at the end of 2014. If you’re an IP&L customer, you are eligible for a solar power rebate of $1,000/kW, up to $4,000.

How do solar rebates work? Similar to getting a rebate card from your local big box store for a dishwasher purchase, state legislatures also provide rebates for solar panel purchases to spur on investment and create new jobs. If you purchase the solar panel system yourself, you qualify for this free cash, which many times is a lump payment back to you. Some solar installers like to take this amount directly off the total installed price, and they'll handle the paperwork for you to make things a lot less complex.

The availability of state and utility rebates were sourced from the Database of State Incentives for Renewables and Energy Efficiency. The better the rebates, the higher the grade.

Indiana Solar Power Tax Credits


Grade: F

Indiana's Solar Tax Credits grade

There is currently no tax credit for Indiana solar panels. Legislators are missing an easy and essential opportunity to incentivize clean energy. This is especially true given the bleak solar rebate and performance payment pictures.

About state solar tax credits: State tax credits are not technically free money. However, they are 'credits' and not 'deductions' which means that if you have the tax appetite to take advantage of them, then they can be a 1-to-1 dollar amount off your taxes instead of a fraction of the cost of the system. So that means they can be an important factor to consider. In certain circumstances, state tax credits can provide a very powerful incentive for people to go solar.

(Keep in mind, we are not tax professionals and give no tax advice so please consult a professional before acting on anything we say related to taxes)

The availability of personal tax credits for solar energy were sourced from the Database of State Incentives for Renewables and Energy Efficiency. The higher the tax credit amount, the higher the grade.

Solar Power Performance Payments

NIPSCO only $0.17/kWh

Grade: D

Indiana's Solar Performance Payments grade

Performance payments are limited for Indiana solar panels. In fact, customers of only one Indiana utility are eligible: Northern Indiana Public Service Corporation (“NIPSCO”). NIPSCO offers a feed-in tariff (i.e. “what they pay you for your energy”) of $0.17/kilowatt-hour (“kWh”) of solar energy produced. The tariff is a good deal for homeowners with solar, considering you pay about two-thirds of that price for electricity from NIPSCO in the first place.

In essence, you'll be getting paid 5 cents per kWh on top of saving the money on electricity generated by the system. How much difference does that make? Well, it'll put about $312 in your pocket every year on top of the usual savings with solar, which reduces your system's payback timeframe by 3 years. That's pretty swell, so thanks, NIPSCO!

The contract agreement with NIPSCO can last up to 15 years.

Explanation of performance payments: Performance payments represent a big chunk of the financial rationale for going solar, and in many instances they make your decision a wise one. For certain states, if you’ve got solar panels on your roof, not only will you be cutting your electric bill down to size, but you'll be getting paid additional cash from your utility company. Pretty awesome, huh? Not only are you generating electricity for yourself, freezing your own popsicles with sun, and feeling like you’re doing something smart for your children or any of the other 4 reasons people go solar, but you are getting PAID!

Utility companies are paying people with solar panels on their roofs because their states say they have to, otherwise they will pay a fee. Therefore, the payment amount to homeowners is typically a little bit less than the amount they would be billed for by the state. For states with these alternative compliance fees, Solar Renewable Energy Credit (SREC) exchanges have popped up. In the above chart, we outlined an estimate of yearly payments a homeowner might expect from the utility company for the SREC credits from their solar energy system.

Expected SREC payments were calculated by using the latest trade values in the SRECtrade database. The availability of feed-in tariffs were sourced from the Database of State Incentives for Renewables and Energy Efficiency. The higher the expected monthly payments, the higher the grade.

We've got a great article if you like to read more about what SRECs are and how to earn them.

Property Tax Exemption


Grade: A

Indiana's Solar Property Tax Exemptions grade

Thankfully Indiana does offer tax exemptions to help make solar power more attractive. First up, you are 100% exempt from all property taxes associated with the increase in home value caused by installing a solar power system. And there is an increase. That’s going to save you a pretty nice chunk of change every year.

About solar property tax exemptions: Property tax exemption status is a pretty big factor when putting together your investment considerations. Some argue that solar power adds approximately 20 times your annual electricity bill savings (if you own the system and are not leasing). Other studies seem to indicate a home price premium about equal to solar panel cost, minus any incentives like the federal solar tax credit.

For many average-sized solar power systems on a house, that can mean adding $20,000 to your home value. And if you don't believe us, believe the bean counters: Many banks and solar financing companies now offer traditional style equity-based home loans for installing solar. An additional $20,000 in property tax basis in many states amounts to a big chunk of change owed back to the state. However, many states have complete exemptions from added taxes when you install solar on your home!

The availability of a property tax exemption for solar energy was sourced from the Database of State Incentives for Renewables and Energy Efficiency. Grades in this category are basically all-or-nothing. Either you got it or you don't. Thankfully, many states have "got it.".

Sales Tax Exemption


Grade: A

Indiana's Solar Sales Tax Exemption grade

You also are exempt from all sales tax (that’s 7% here) on the purchase of your solar power system, which is a really nice benefit in a state without much going for it in terms of solar policy. If all this is sounding complicated and discouraging, don’t worry – the solar installers we partner with can take care of all these details for you and make sure you save the most money possible.

What's the deal with solar power sales tax exemptions? When states give you a sales tax break on solar, we notice. You should too. State sales tax exemption status for the purchase of solar energy systems were sourced from the Database of State Incentives for Renewables and Energy Efficiency. Sales tax exemptions, if present, were all 100%. A handful of states are completely exempt from sales tax regardless, and therefore received ‘A’ grades by default (OR, DE, MT, AK, and NH).

The consensus on Indiana solar power rebates and incentives

Indiana has a lot of work to break into the list of the top states for solar. But we know you can do it, Hoosiers! Do we have to start throwing chairs around here!? As we said up front, there is still a lot of work to be done, but progress is progress, even if it’s only minimal. To make more progress, legislators should start with a stronger, mandatory RPS. If you add in a statewide rebate program for Indiana solar panels and/or a really good feed-in-tariff like NIPSCO offers, that’d really improve payback timeframes statewide. Until those or other improvements happen, however, we still have Indiana rated as a “C.”

I don’t know about Indiana is a solar energy friendly state. I know for the fact that I am living in Mishawaka, IN and having a 5kw solar system installed. I got zero credit for my solar electricity that goes to the grid. There are less than a dozen solar systems installed in Mishawaka. It turned out that Mishawaka owns the electric comapany. It is a subcontract from AEP. That is why Mishawaka discourage its citizens to install solar system on their rooftops. I am going off grid as much as I can. Not happy seeing my investment is going… Read more »


only private utilities have to allow net metering, city owned utilities are exempt from the law.


Indiana is a raging shithole of backward corrupt politics that ALWAYS puts the throatfucking of big business ahead of citizen wellbeing. Politicians in this state will choose corporations over citizens EVERY. SINGLE. TIME. It’s time to abandon this shithole for more inteligent places..


Installed a 14Kw system on my new Sheridan home. Bills are 48 dollars a month (only because BOON REMC charges me to be on the grid).


Sadly, I have to admit as a true Hoosier (i.e. I was born in Indiana), that despite some minor progress, Indiana is a very backwards way behind state compared a lot of others. Even though it doesn’t directly relate to this, a state by state analysis was done of major US cities. The analysis was done of nearly every city approximately the size of Lafayette and larger. The study was done of a waste to production comparison. Sadly, even our state capital (Indianapolis) was almost dead last and rated as one of the most wasteful states out there. We as… Read more »


The payback is very off, you have a $5/watt rate. Several companies in southern Indiana, like Ohio Valley Electric in Newburgh, are installing them for $3.50/watt.


i was wandering about the interpretation of that source, so i called the department of revenue of indoana. and the legal department from and the lawyer told me that the sales tax exemption is currently only approved for the manufaturers of solar equiptment..

We need to change the way we live because of our future generations,
Our planet will not be able to survive the damage that is being done if
we don’t come up with a way to change what we are doing now. Everyone
will suffer over it. I hate what has happened to our planet already, we need
to save it ! I wish more people could get solar power & windmills. Maybe in
the years ahead we can figure out a way.


I live in southern Indiana, and installed 6500 watts worth (28 panels, 250 watts each) about 5 years ago. I have been very happy with the electricity bills, although our utility (a so-called co-op) pays only 6. something cents per kilowatt. I have made an average of a meg a month all summer. Now I have someone looking into the SRECs for me, although I have little faith that it will turn out.
