Here’s a question that probably doesn’t get asked enough when choosing a solar company:

Who are you going to call when your system needs service five or ten years from now?

Solar is a long-term investment. Companies can come and go, equipment eventually needs attention, and sometimes homeowners are left with systems installed by someone who is no longer around to service them.

OnSite has been designing, installing and supporting solar systems across Montana since 2012. More than 1,200 projects later, we’re still here—and we've even stepped in to help service systems installed by companies that aren't.
That longevity matters to us just as much as the installation itself.

It’s also pretty cool to have been recognized as a Top Solar Contractor in the U.S. eight times along the way. ☀️

We’re not interested in simply putting panels on your roof. We want to be the solar company you can still call years later.

Solar + battery storage is a big decision for your home, and you should have people you can actually ask questions along the way.

Margie shared this after OnSite installed solar panels and battery storage at her new Montana home:

“Throughout the process, the entire team from sales through installation were incredibly professional and responsive and were always available to answer our questions. We couldn't be happier with our new system and with our decision to go with OnSite!”

This is still exactly the experience we want our customers to have: thoughtful guidance, responsive people, and a team that's here for the long haul.

Thanks for trusting us, Margie. ☀️

Thinking about solar in 2027?
Call us before 2026 is over.

Not because we're going to tell you that you need to sign a contract tomorrow. Quite the opposite.

A good solar project takes some planning. We need to understand your energy use and goals, look at your property, talk through whether solar or energy storage makes sense, and design a system around what you actually need.

Starting the conversation this fall gives you something valuable heading into a new year: information.

You can understand your options, ask questions, get real numbers for your property and decide what makes sense from there.

So if solar has been sitting on your “maybe next year” list, this is your reminder to move it to the “let's at least figure it out” list.

When the grid goes down, will your solar keep working?

Not necessarily—and that's something we think more people should know before an outage happens.

For one rural Montana homeowner, that distinction became very real when downed power lines sparked a fire across the river from his property. With high winds threatening to carry embers his direction, his energy storage system kept his well pump running, giving him access to water and hoses around his home and outbuildings if he needed them.

Fortunately, the fire was contained. But it’s a pretty powerful example of why battery backup isn't always about keeping the lights on.

Our newest blog looks at solar + energy storage in Montana, what you can actually keep powered during an outage, and how to think about how much backup you really need.

Tired of pushy sales people knocking on your door to sell you solar? We are too.

Interested in solar but having a hard time trusting the high-pressure sales pitch from the door-to-door salesperson? We're here to help'

Our founders have been providing comprehensive solar energy services in Southwest Montana since 2004 the old fashioned way. Our business is generated through hard-earned relationships and business reputation, and our sales philosophy is to enable our customers with information, not high-pressure sales pitches.

If you have been repeatedly door-knocked for solar, in some cases by the same company in the same month, we know how you feel. And you can rest assured that for over two decades we have never taken that approach -and we never will.

What does a decade-long relationship with your solar company look like?

For Eagle Mount Bozeman, it looks like three generations of solar. ☀️

Eagle Mount first invested in solar more than a decade ago as part of a long-term strategy to manage the energy costs of its growing campus. As the organization expanded and solar technology evolved, they kept building on that original investment—and kept coming back to OnSite.

Their newest 37 kW expansion brings the campus to 62 kW of solar, helping Eagle Mount put more of its resources where they belong: toward its mission and programs.

We recently took a closer look at what more than a decade of solar has meant for this incredible Montana nonprofit—and what other organizations can learn from it.

The best compliments aren't about solar.

They're about people.
We're incredibly grateful when customers take the time to share their experience.

"Their team is thoughtful, organized, and easy to work with."

Thank you, Kyle, for the kind words. Reviews like this remind us that every project is about more than panels and electricity—it's about earning trust.

Thank you to everyone who has trusted OnSite Energy over the past 14 years. We don't take it for granted.

Every kilowatt doesn't have to travel hundreds of miles.

One of the biggest misconceptions about electricity is that it's simply "there" whenever we need it.

In reality, the grid has to balance supply and demand every second of every day.
That's why local energy generation matters.

Every home, ranch, business, nonprofit, and public building that produces electricity where it's used helps reduce dependence on moving every kilowatt across long-distance transmission infrastructure.

That's one reason we've spent more than 14 years helping Montanans design solar systems that fit their unique needs.

Whether the goal is lowering operating costs, increasing energy independence, or adding battery backup, every project contributes to a stronger, more resilient energy future.

We explored this concept in our latest article if you'd like to learn more:

☀️ Why solar can help ease pressure during peak demand

Solar doesn’t just produce electricity. It can reduce how much power the grid needs to supply when demand is at its highest.

Most conversations about solar focus on reducing electric bills.

But there’s another reason utilities, researchers, and energy planners are paying attention to distributed solar:

Timing.

When electricity demand peaks, solar is often already producing.

That means homes, businesses, nonprofits, and agricultural operations with solar may draw less electricity from the grid during some of the busiest hours of the day—helping reduce the amount of power grid operators need to deliver all at once.

In our newest article, we explore:
☀️ What peak demand actually means
☀️ How solar can reduce strain during peak-demand hours
☀️ What the Northeast’s record heat wave taught us
☀️ What it could mean for Montana’s energy future
