If you’re looking for the best solar companies in Montana, chances are you’ll read through a handful of company reviews. Unfortunately, many other resources fail to consider the most crucial local factors for Montana homeowners, specifically, like weatherization to protect against the abundant snowfall and high winds the state sees. The EcoWatch team considers this and many other local criteria to ensure you’re matched with the best solar contractor for your needs.

What Are the Top 5 Solar Companies in Montana?

The table below provides an at-a-glance comparison of the best solar companies in Montana. You might be surprised to see that some of the most popular solar installers don’t appear on our list. We have left companies like Vivint Solar, for example, out of our ranking because of ongoing lawsuits with solar customers, poor performance or coverage in Montana or other issues that could prevent you from getting the service you deserve.

1. OnSite Energy

OnSite Energy is a small solar company based in Bozeman, Montana. It provides the kind of superior customer service you’d expect from a local company, and it manages to maintain 5-star reviews and overwhelmingly positive feedback from most customers. Its technicians are abundantly helpful when it comes to securing financing and taking advantage of solar incentives — including the federal tax credit and other tax exemptions — and they always maintain professionalism.

OnSite is a full-service company, providing access to a wide range of products and brands, including many of the more popular options, like Tesla Powerwall batteries. To maximize customization opportunities for your home solar project, it also provides a slew of services, including panel installations, battery backup and electric vehicle charger installations and solar system monitoring.

OnSites warranties vary quite a bit based on the manufacturer of the equipment you choose. The best coverage lasts 25 years for equipment failures and power production dips, which provides some peace of mind that your panels will maximize energy output for years to come.

Pros for OnSite Energy

OnSite Energy is a local leader in customer service, and it’s a certified B Corp that gives back to conservation nonprofits, which is a big reason we’ve chosen it as the best overall solar company in Montana.

  • Excellent customer service
  • Nice product and service variety
  • Great warranty coverage
  • Certified B Corp

Cons for OnSite Energy

It’s tough to find any significant downsides to working with OnSite Energy. If we had to name one, it would be its lack of offering solar leases and power purchase agreements (PPAs), although we don’t recommend these financing options anyway. It can also be slightly expensive compared to other companies in the region.

  • No solar leases or PPAs
  • Slightly expensive

2. SBS Solar

SBS Solar is a relatively small local solar panel installation company based in Missoula that provides excellent customer service. There are many customer comments about the timeliness and professionalism of its employees, as well as the overall timeline and connection for net metering being quick.

SBS Solar carries fewer solar equipment brands than our top pick, but it still provides access to some of the more popular options, like Canadian Solar and Enphase. The array of services provided by SBS Solar still allows for some system customization, as you can choose from add-on services like battery and electric vehicle charger installations, as well as whole-home energy audits.

SBS Solar only accepts cash payments and solar loans, so customers looking for leases or PPAs are out of luck.

The equipment from SBS is covered by the company’s 25-year warranty for damage and power production, which is ideal for Montana homeowners concerned about panel performance in harsh winter weather.

Pros for SBS Solar

SBS Solar maintains a record of wonderful customer service throughout Montana. It has a good range of services available, and the warranty coverage is precisely what most MT homeowners look for in a solar energy system.

  • Great customer service
  • Many add-on services provided
  • Robust warranty coverage

Cons for SBS Solar

SBS Solar doesn’t accept leases or power purchase agreements (PPAs), so it might be prohibitively expensive for some homeowners. It also has limited solar equipment brands available.

  • No leases or PPAs
  • Only a few solar brands available

3. Solar IPS

Solar IPS (Independent Power Systems) is a comparatively small regional company based in Boulder, Colorado, that serves Montana’s greater Helena, Bozeman and Butte areas. This company is small enough to maintain a good reputation for customer service but also large enough to keep prices low and have flexibility for installation timelines. However, there are a few customer complaints online about delayed service after installation.

Solar IPS primarily provides SunPower panels, which are some of the most efficient solar panels in the industry. This equipment often results in the greatest savings on your electric bill, and they’re ideal for Montana residents, as they maximize energy production. They’re also backed by an industry-leading, 25-year comprehensive warranty.

Solar IPS provides access to many other brands for customization, but it only handles panel and battery installations and system maintenance. Customers looking for other add-on services will need to look elsewhere.

Solar IPS also has the most solar financing options, making clean energy highly accessible to many Montana homeowners.

Pros for Solar IPS

  • High-efficiency equipment
  • Robust warranty coverage
  • Many financing options available

Cons for Solar IPS

Solar IPS has some instances of spotty communication, particularly after installation. It also only offers standard services.

  • Some reported communication issues
  • Limited services provided

4. Harvest Solar MT

Harvest Solar MT is a locally owned and operated installer based in Bozeman, Montana. Like several of our other top choices, this company maintains near-perfect customer reviews online. The majority of customer testimonials praise Harvest Solar MT for its knowledgeable and helpful technicians, its willingness to walk customers through the entire process and the professionalism of the entire staff.

Harvest Solar provides a few brands of solar equipment to choose from, but it only offers solar panel and battery installations. Customers looking for customization on their solar projects or add-on services like EV chargers will need to turn elsewhere.

This company only accepts cash purchases and loans through third-party lenders, so it might be prohibitively expensive for customers who need lease options or PPAs to go solar.

Additionally, the warranty coverage is limited to the manufacturer’s warranty.

Pros for Harvest Solar MT

Harvest Solar MT has a reputation for customer service and dependability. It carries several equipment brands for some customization.

  • Good customer service
  • Professional and trustworthy technicians
  • Nice range of products available

Cons for Harvest Solar MT

Harvest Solar MT doesn’t accept leases or power purchase agreements (PPAs), and it has limited services in its repertoire. The warranty coverage is also limited to what the manufacturer provides.

  • No leases or PPAs
  • Just a few services available
  • Limited warranty coverage based on manufacturer

5. Big Sky Solar 

As the name implies, Big Sky Solar is a company local to the Big Sky State. It has been serving Montana since 2003 and has maintained a good reputation for quality customer service and a commitment to making solar power systems more accessible. Most customers who go with Big Sky are pleased with the communication throughout the process and the techs’ willingness to help secure financing and take advantage of solar rebates and state tax credits.

Big Sky Solar offers the basic services, like solar panel and battery installations, and it also handles electric vehicle charger installations. It has just a few brands of equipment, but they’re the more popular ones, like Tesla and Enphase. All panels and service comes backed by a 25-year warranty for equipment and workmanship. Unfortunately, the company doesn’t offer a separate power production warranty.

Big Sky only accepts cash purchases and solar loans. While these are generally the options we recommend, the lack of solar lease options and power purchase agreements (PPAs) might exclude some customers.

Pros for Big Sky Solar 

Big Sky Solar has a great reputation for quality customer service and communication. It has longevity in the industry, offers basic and add-on services and has good warranties for equipment and workmanship.

  • Excellent customer service
  • Long history of success in the solar industry
  • Excellent warranty coverage for equipment and workmanship

Cons for Big Sky Solar 

While Big Sky Solar has good warranty coverage for equipment and labor, it doesn’t cover power production, which is important to many MT homeowners. It also doesn’t accept leases or power purchase agreements (PPAs).

  • No warranty for power production
  • No leases or PPAs

EcoWatch Criteria for Selecting the Top Solar Company in Montana

The EcoWatch team ranks solar companies based on individual scores for over 20 criteria. You can read about our entire process on our methodology page or see the most significant factors we consider below.

Warranty

Given that going solar typically costs thousands or even tens of thousands of dollars, most homeowners want some kind of assurance that their system will last. Solar warranties cover equipment and/or labor in most cases.

For Montana homeowners, warranties that guarantee a certain level of power production are typically the most important. These ensure your system will maintain a certain output level even after years of being battered by Montana’s harsh winters.

Year Founded

Solar power is becoming more popular in Montana, which is wonderful news. However, the rise in demand has led to some below-average, “fly by night” companies popping up throughout the state. These installers very rarely provide the same level of service as well-established companies, and if they go out of business, your system’s warranty will be voided.

The EcoWatch team ranks solar panel installation companies with longevity a bit higher for these reasons.

Services Offered

As you might have noticed based on our reviews, not every solar company provides the same services. Some companies — like Harvest Solar MT — only tackle panel and solar battery installations. Others include add-on services like EV charging stations, solar monitoring, maintenance and more.

Companies with a broad range of services tend to rank higher because they appeal to those looking for standard set-ups as well as customized installations.

Brands of Solar Equipment Offered

Solar panel installation companies typically partner with one or more manufacturers and only install those brands. Many Montana residents choose their solar contractor at least in part based on the brands it carries. Those looking for the cheapest solar panels and those looking for the highest efficiency panels will need different equipment, so companies that offer many options rank higher.

Industry Affiliations

There are a number of solar organizations and associations — many of which are nonprofits — that strive to make renewable energy more accessible and affordable throughout Montana. Companies that affiliate themselves with these organizations rank a bit higher because it’s a sign that the installer cares about the solar industry and about making responsible choices from a renewable energy standpoint.

Some affiliations we look for include the North American Board of Certified Energy Practitioners (NABCEP), the Solar Energy Industries Association (SEIA) and the Montana Renewable Energy Association.

Size of Company

The size of the company you choose to handle your installation can have a surprising impact on your overall experience.

Larger national companies tend to have lower pricing and more flexibility with scheduling, but they sometimes lack the customer service of smaller local companies. They also tend to have greater resources and can sometimes expedite the permitting and installation process for you.

Smaller local companies usually have better customer service, and many have closer relationships with local electric companies, allowing them to expedite connection to the grid. However, smaller companies sometimes have higher pricing unless they offer deals or discounts to undercut the larger corporations.

Solar Pricing and Financing

Lastly, we look at a company’s overall pricing, the cost-to-value ratio, and the financing options afforded to customers.

The overall installation cost of photovoltaic panels from a company will always be a crucial factor, but we put more emphasis on the value provided for the money. For example, companies typically have to charge more for high-efficiency panels, but they can usually save you more on your energy bills in the long run and end up being worth the investment. This is especially true in Montana, where panels have to make up for lost production due to snow coverage.

Companies also all offer different forms of financing, which ultimately decide your upfront and long-term costs. Those that accept cash purchases and solar loans only will cost more upfront, but they save most customers more over time as compared to leases and power purchase agreements (PPAs). Companies that provide access to lease options and PPAs make PV systems more affordable in the short term, ultimately making renewable energy more accessible.
