If you've been thinking about switching to solar power but feel overwhelmed by the many options in Montana, you're not alone. We’re here to help you compare your options and get the best deal.
In Montana, a typical residential solar panel system costs $9,800 to $28,000, depending on the size of your system and what financial incentives you qualify for.
Jump to insightThe federal solar investment tax credit (ITC) is the most significant way to lower the cost of installing solar panels. Montana also has statewide tax breaks and loan programs to help make going solar more affordable.
Jump to insightWatch out for solar scams. Some solar reps might use pushy sales tactics, and you could end up with monthly bills higher than expected.

If you want to minimize your initial cost, you can typically lease your solar equipment. However, you won’t be eligible for the federal solar investment tax credit (ITC) if you lease because you won’t technically own the system.
» BEST STATES FOR SOLAR: Montana ranked 25th in 2024
In our experience, the best solar energy companies have a few things in common: great reviews, transparent contracts, reliable equipment and comprehensive warranties. We also suggest hiring NABCEP-certified installers. This shows you the company takes its business seriously. Here’s what else to look for.
Average solar panel costs in Montana typically range from $9,800 to $28,000. The size of your solar panel system is a big factor in your total cost. It also depends on what incentives you’re eligible for, the condition of your roof and how much sunlight exposure it gets.
Most installers set the price according to the system's wattage, with a typical cost between $2.50 and $5 per watt. In Montana, the average cost per watt is $2.6.
Average solar installation cost by system size in Montana
5 kW | 6 kW | 7 kW | 8 kW | 9 kW | 10 kW | |
---|---|---|---|---|---|---|
Before federal tax credit | $12,700 | $14,539 | $16,771 | $19,280 | $21,159 | $23,240 |
After federal tax credit | $8,890 | $10,177 | $11,740 | $13,496 | $14,811 | $16,268 |
The estimated costs above do not include the cost of a solar storage battery, which sometimes costs as much as the panels ($7,000 to $18,000). Solar batteries are a must if you want real energy independence and essential if you go off-grid.
Getting solar panels is like buying a car. You could pay cash, but many finance instead. A solar loan works like most other types of loans — there is an application process, and you pay it back over time with interest.
Solar panels are designed to last 25 to 30 years.
Some solar companies suggest using a home equity line of credit or loan to finance a solar installation. This can be a financially beneficial option — home equity interest rates are relatively low, and it lets homeowners to take advantage of the federal solar tax credit.
Leasing solar panels is sometimes cheaper in the short term, but you’ll be disqualified from some of the best financial incentives, including the federal solar investment tax credit.
» SOLAR PANELS: Lease vs. buy
The federal solar investment tax credit (ITC) is usually the most significant financial incentive for homeowners. It provides a 30% tax credit on your total system costs, including equipment, labor and permits.
The ITC drops to 26% in 2033 and then 22% in 2034.
For example, if you spend $10,000 going solar, the ITC is worth $3,000. Let’s say you owe $15,000 in taxes that year. The ITC reduces what you owe to $12,000. It’s nonrefundable, meaning you can only claim a credit up to the amount of tax you owe for the year. However, the credit rolls over to the next tax year if you don’t use the full amount.
Two additional statewide solar incentives in Montana also encourage residents to invest in renewable energy:
» GREENEST STATES: Montana ranked 35th in 2024
Based on feedback from several solar customers in Treasure State, the general consensus is that solar investments are worth it in Montana. On average, Montana homeowners with solar panels avoid $41,487 in total utility costs over 25 years.
With electricity costs continuing to rise, more Montana homeowners find solar power is financially worth it in the long run. The return on investment of a solar panel installation depends on your system's efficiency and size. Assuming an upfront purchase, it takes about 11.7 years to break even (when your savings with solar panels make up for the cost).
Homeowners with solar panels typically save $20,000 to $90,000 over 25 years.
Going solar is still expensive, though. Some solar customers we’ve talked to are understandably frustrated when equipment doesn’t work, and their solar company won’t help them. If you run into a production issue and can’t resolve it quickly, you might end up paying more than you are now — especially if you finance. Your solar loan payment is due whether or not the panels are working. That’s why it’s important to hire a reputable solar company.
Use the National Renewable Energy Laboratory’s PVWatts Calculator to estimate how much electricity a solar panel can produce over a year on your house — just type in your address. Project Sunroof is a free solar savings estimator powered by Google Earth imagery.
» STILL NOT SURE? Solar energy pros and cons
There’s no totally free option to get solar panels in Montana that we’re aware of. Unfortunately, scams that promise free solar panels can cost consumers a lot of money. However, you can lease solar equipment to reduce your upfront cost. You won’t own your panels, though, so you won’t be eligible for the federal solar investment tax credit.
» FREE SOLAR PANELS: Are they really free?
There are no laws in Montana that prevent homeowners associations from restricting solar panels.
Plenty of unshaded roof space that faces south or west is best for optimal sun exposure. Montana averages 4 to 5 peak sun hours each day. However, if you have a lot of shading around your house, they might not get enough sun to power your home. It’s also smart to upgrade any old, inefficient appliances first. Solar photovoltaic (PV) technologies, more commonly known as solar panels, absorb sunlight and convert it into usable electricity.
We’ve also heard about problems with leaks and roof damage caused by the installation of solar panels, leading to frustration and difficulties in getting repairs. As a rule of thumb, if your roof is more than 10 years old, consider fixing it before going solar. Installing solar panels on an old roof might mean you have to remove the panels, replace your roof and then reinstall the panels. This will cost around $5,000 for a 19-panel setup.
A solar broker is a middleman or intermediary who helps connect homeowners with solar installation companies. A solar installer specializes in designing, procuring and installing solar panels and related components.
Ultimately, deciding between a broker and a solar installer depends on how much you want to be involved in the process. A broker can be helpful if you value convenience. If you want more control and potentially lower costs, working directly with a solar installer is best.
Net metering is a system of give-and-take between you and your utility company. It lets you access power from the grid when your panels don’t generate enough electricity.
Net metering also lets you earn credits for sending any excess solar energy to the grid. These credits can offset the cost of electricity consumed at other times.
In Montana, you get compensation for your energy as a credit on your electric bill. How much you earn and limitations can vary from utility company to utility company. For example, NorthWestern Energy has a 50-kilowatt (kW) size limit for systems, while Yellowstone Valley Electric Cooperative has a size limit of 15 kW.
The Consumer Affairs Research Team used a research-backed, data-driven approach, which was informed by our expert editors, to choose the best solar companies. For this guide, we objectively weighted several key features to get our final rankings:
Reviews, ratings and testimonials: 40%
We analyzed solar company reviews by verified solar customers to gauge real-world satisfaction. Companies with generally positive feedback on our site scored highest in this aspect. Those with the most 4- and 5-star reviews by verified Montana customers were given preference.
Warranties: 20%
A long warranty is important — it shows that a company stands behind its products and services. We compared companies on both equipment and craftsmanship warranty terms. All of our top picks for professional installation have warranties or production guarantees of at least 10 to 25 years.
Equipment selection: 20%
We evaluated each company’s selection of solar panels, storage batteries and inverters. Those with proprietary technology or a wide equipment selection from trusted brands ranked highest.
Financing and payment options: 10%
We gave preference to companies that offer multiple payment and financing options for transparent terms and conditions.
Reputation and local experience: 10%
We prefer to recommend those with a longer time in business and a solid track record of reliability in Montana. Solar is a booming industry, and there are some sketchy installers out there. Company history, current reputation, mission and values were also considered.
Our goal is to highlight solar companies that are best equipped to meet most Montanans’s needs. The team regularly evaluates customer reviews, company information and industry trends to update our top picks, which include:
