** What's new for 2019 **
Ah, Big Sky Country. The Rocky Mountains and Montana’s wide open spaces make it a natural paradise. Between Yellowstone and Glacier National Parks, and parts of the Historic Lewis and Clark Trail, you could stay out under the sun for months, exploring the Treasure State. Using clean energy like solar power would really help Montana protect its treasures. Here’s what the state legislature has been doing to promote renewable power sources.
While there have been some good solar conversations going on in Montana as of late, there hasn’t been much actual movement in renewable energy policy coming from Helena. With the coming deadline for its RPS, Montana has an opportunity to enact new, forward-thinking renewable energy policy with long-term goals that reflect a commitment to getting us off traditional fuel sources and moving us toward a cleaner future.

Your Solar Strategy in Montana
Figuring out the best way to go solar in Montana 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 Montana
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. That might look a little complicated to you, so let's break it down:
The green bars show the return if you pay up front. As you can see, there's a big payment in year 1, which gets slowly reduced over time. The green bars cross the "$0" line at year 16, which is when the system will have paid back your initial investment with electricity savings. Then, our example goes to year 25 (which is when most solar panel warranties end), where you'll end up with just about $9,400 in total profits. Not bad! That's because even though Montana has pretty cheap electricity, Big Sky country gets some good doses of sun.
The orange bars, on the other had, show what happens if you take a loan or Home-Equity Line of Credit (HELOC) to pay for the system. You don't put any money down, but you do get the 30% Federal tax credit, meaning you actually come out ahead in year 1. The bars dip below the $0 line after 6 years, because your loan payments (over a 15-year term) will exceed your energy savings by a little each year. Still, once you pay off the loan, the savings start stacking up quickly. In the end, you'll come out a few thousand dollars ahead over the 25-year estimate.
Finally, the blue bars represent a smaller (2-kW) system purchased with a loan. Just in case you don't have a ton of equity.
Read on to find out more about each option!
Option 1: Paying cash for solar
Paying up front used to be the only way to get panels on your roof, and it's still the option that allows you the most control. But it isn't the best option from a percentage return on investment standpoint—that award goes to the solar loan.
Still, an outright purchase returns the most money over time, because you own the system from day one and reap all the benefits—including the Federal solar tax credit of 30%, the state solar tax credit of $1,000, and some decent energy bill savings.
In our example, you put down $20,000, but by the end of year 1, those tax credits and energy savings will erase a bunch of it. Over 25 years, your system will have produced nearly $9,400 in income.
Net Present Value: -$1,618
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 Montana's-$1,618 NPV on a 5-kW solar system means you'd be that much better off investing your money in stocks over 25 years than in Montana solar. But check out what happens to NPV if you buy the same system with a loan that you can pay back over time.
Here’s an example of how the numbers work for a purchase of a 5-kW rooftop solar system, for a married couple in Montana:
- Installing a typical 5-kW solar system should start at about $20,000. That's cheaper than solar has ever been, but it probably still seems expensive. Stay with us.
- At tax time next year, the Feds will give you a 30% tax credit, which means you'll get $6,000 back next April. Note: you can take the credit over several years if you don't owe $6,000 in Federal taxes this year.
- Next, subtract Montana's $1,000 state tax credit. With the two credits, you'll have spent just $13,000 on that solar system after year 1!
- Then there's your first-year energy savings. That's another $665, and it brings the cost after 1 year to just $12,335. The rebate, tax credits, and energy savings have taken about 40% off the cost of your system!
- With those energy bill savings rolling in, your system will pay itself back after 16 years. Once that happens, you’ll be seeing over $950 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 $9,394 with an internal rate of return of 4.6%. That's better than most financial investments you can make!
- On top of those returns, your home's value just increased by $17,000 too (your expected electricity savings over 20 years)!
- And speaking of doing good for the environment... your system will create some green for the earth by not using electricity from fossil-fuels. In fact, the energy you’re not using has the carbon equivalent of planting 101 trees a year, every year your solar power system is humming.

Option 2: Using a loan to pay for solar
This is where we tell you that taking a loan for solar panels is a no-brainer, because it means investing in an income-generating asset. And it's true! That's because the state has nice a tax credit and rebate, and gets enough sun to make solar worthwhile, generating a good deal of income for you after you pay your loan off. A loan is the only solar investment in Montana that compares favorably with an investment in the stock market.
Here's the important stuff:
As you can see from the chart above, you'll start out with a big windfall, because with a loan, you're not putting any money down, and you get those tax credits just like if you paid $20,000 up front for your system. You'll come out ahead nearly $6,000 after the first year! In the 14 years that follow, your loan payments will actually cost a little more than the money you'll be saving in electricity, but just think of it like a monthly deposit into a savings account.
And that solar "savings account" will pay dividends after the loan is paid off in year 15. You'll be saving tons of money every year because you'll own the system outright. At the end of our 25-year example, you'll be $2,765 to the good, which is great for an investment where you put nothing down!
A solar purchase like this will make sense for you if the following is true about you and your current situation:
- You can qualify for a solar loan or home-equity line of credit (HELOC) for $20,000 with a fixed rate of 4% or lower and a 15-year repayment period.
- You have an appetite for making a little money with a long-term investment, while also producing benefits for the environment.
Net Present Value: $9
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 Montana's $9 NPV on a solar loan means you're bascially breaking even with an investment in the stock market. That's pretty great news!
Here’s how the numbers pencil out for a married couple making a Montana solar purchase with a loan:
- Installing a typical 5-kW solar system should start at about $20,000. That's how big your loan will need to be to cover it.
- The electricity bill savings in the first year of operation will total $665, but your loan payments will be $1,775, for a difference of $1,110, or about $93 per month.
- But here come the tax credits! Because you've technically "paid" for the system with your loan, you'll get a state tax credit of $1,000 and a Federal tax credit of 30% of system costs, or $6,000! After you make those loan payments, you'll end up with an extra $5,889 at the end of the first year.
- When your loan’s paid off in year 15, you’ll see over $940 per year in savings until the end of your system’s life.
- For our 25-year estimate, you'll see pretty nice returns, to the tune of $2,765 after all the payments. That's a huge amount of money for a zero-down investment!
- Finally, the environmental benefits cannot be overstated. Operating your system will take as much carbon out of the air as planting 101 trees every year!

Option 3: Buying the electricity, not the panels with a Power Purchase Agreement (PPA)
Montana 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!
Montana 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 Montana:
Montana's Renewable Portfolio Standard
15% by 2015
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.
Montana’s RPS was phased in over three multi-year periods. In 2008 and 2009 all public utilities and competitive electric suppliers had to generate at least 5% of retail sales from renewable resources. Starting in 2010 that minimum was raised to 10%. In 2015 the minimum amount of renewable resource-based electricity again rose to 15%, where it will remain.
Montana’s RPS has been 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.
15% by 2015 looked like a strong goal in the beginning, but 2015 has come and gone, and without further action, Montana will be stuck with no clear direction on future renewable development. The Renewable Portfolio Standards in other states go further, mandating from between 20% and 40% renewable energy by next decade. So while 15% by 2015 was an excellent short-term target, lawmakers in Helena have some work to do in the near future if they really want to spur incentives for solar power. The program could be even better if it had specific targets for Montana’s solar panels.
Montana's RPS solar carve out
The one thing Montana doesn’t include in its RPS is a specific requirement for solar. If the RPS contained specific carve-outs for clean and efficient solar panels, or mandates for environmentally necessary increases in distributed generation, you’d see even stronger incentives for residential solar power.
Montana Electricity Prices
Montana homeowners pay an average of 11 cents per kilowatt-hour (“kWh”) of electricity. That’s really cheap! Nearly two cents below the national average. We know you like paying less now, but the long term costs of cheap electricity are simply astronomical. All that cheap electricity is produced by burning fossil fuels. Tons and tons of greenhouse gas spewing fossil fuels. As those environmental costs rise (and rise), monthly electricity bills are inevitably going to climb as well. Solar power is already cheap and efficient, even compared to current fossil fuel prices. Just imagine how much cheaper it will be in ten years, or even twenty, when your solar power system is still humming along. Just remember to thank us for the tip.
Montana Net Metering
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.
Montana requires all investor-owned utilities to offer net metering. All surplus energy you produce will be applied as a credit to your next monthly bill. Unfortunately, if you manage to run a surplus for an entire 12-month period (customers may elect to start yearly cycles in January, April, July or October), the accumulated surplus is granted back to the utility without compensation. We think they should cut you a check. We’d also like to see the current 50 kW size limit raised or removed for net metered systems, allowing larger commercial and industrial customers to meet on-site generation needs.
While electric companies other than investor-owned utilities are not covered by the regulation, the Montana Electric Cooperatives’ Association (“MECA”) has adopted model net metering/interconnection guidelines that mirror state law, but with an even lower 10 kW system size limit. Net metering is available in whole or part from most MECA members.
Montana Interconnection Rules
Interconnection is a mixed bag here as well. While systems up to 10 megawatts are ensured access to the grid for all Montana utilities, including co-ops, all systems are also must be equipped with a redundant external disconnect switch that serves only to cost you extra money at installation. The state regulation does not mandate a standard agreement, but NorthWestern Energy does use a standard agreement for getting net-metered systems hooked up to the grid.
Solar Incentives in Montana
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 total system 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 Montana measures up:
The availability of state solar incentives for residential solar systems was sourced from the Database of State Incentives for Renewables and Efficiency, utility company websites, and the state public utility commission.
Montana Solar Power Rebates
Way back in 1997, Montana had some of the first rebates programs. Sadly, here it is 20 years later and the state is lagging behind in helping its citizens go solar. We'd like to see a return to even the modest rebates that were here just a couple years ago, but we're not going to hold our breath.
The good news is the rebates of the past helped bring the costs of solar down so far, you can expect it to still make financial sense here in good ol' Big Sky country.
Montana Solar Tax Credits
In addition to the solar power rebate from NorthWestern Energy, when tax day rolls around you’ll also get some cash back from the state. Montana’s Residential Alternative Energy System Tax Credit offers a tax credit on 100% of the price of a solar power system, up to a maximum of $500 for individuals and $1,000 for households with more than one taxpayer. The credit may be carried over for up to four years.
Montana Solar Performance Payments
There are currently no performance payments available for solar power in Montana. If the RPS set higher long-term goals, we can virtually guarantee that utility companies would offer incentives to help you make the switch to solar. Why are we so certain? Only because high RPS targets have translated into big-time incentives for residential solar power almost everywhere that a strong RPS has been implemented.
Property Tax Exemption
100% for 10 years
In addition to the money you’ll get back on your state income taxes, our legislators have made sure you’ll also save bundles of money in property taxes. Installing a solar power system adds a great deal of value to your home. Thanks to the Renewable Energy Systems Exemption, up to $20,000 of assessed value from your solar power system is 100% exempt from all property taxes for 10 good long years. That’s thousands of dollars saved over the next decade!
Sales Tax Exemption
No State Sales Tax
Without a state sales tax in Montana, you pay zero extra dollars on the installation of that beautiful new solar panel system! Thanks, Montana!
The consensus on Montana solar power rebates and incentives
Despite the reputation for cold winters, Montana actually gets a whole lot of sun. In fact, the solar resource potential for most of the state meets or exceeds that of even the sunniest parts of Florida. Unfortunately state legislators are doing only a so-so job of promoting solar power here. What’s really needed is an RPS strong enough to kick-start a strong performance incentive program. With ongoing performance payments for solar power production, the merely adequate 11-year payback timeframe would drop dramatically. For now, we give out a tentative “C” grade here, but if that rebate goes away, Montana is going straight to “F” territory, with a bullet.
