Its one and two star share is 2 points above the typical installer in Bozeman. Across Montana, 7 of the 36 installers whose breakdown Google has published carry a higher share than this one.

The percentages are Google’s own arithmetic over every review it holds, not a sample we assembled. Separately we hold 99 review texts for this company, quoted below. Google publishes review ages rather than dates, so every date here is approximate.

    I’ve worked with OnSite Energy on many solar projects across Montana and have been consistently impressed with their professionalism, technical knowledge, and commitment to quality. Their team is thoughtful, organized, and easy to work with, and they clearly care about delivering systems that are well-designed, reliable, and built to last. What stands out most is their attention to detail and their willingness to do things the right way. Whether it’s a residential installation or a larger commercial project, OnSite brings the experience and care needed to make the process smooth and the final

Topics Google derives from the review text, with how often each appears. A frequent topic is not a good one: “price” turns up in praise and in complaints alike.

What the company says about itself

Taken from its own website. We have not checked any of it, and a sentence on a website is not evidence.

    Its website also mentions established, but not in a sentence we can quote cleanly.

    As Google published them when we last read the listing, not a live check. Ring before you drive anywhere.

    Ordered by how much we can tell you about each, which is not an order of quality. We do not know which of these is better and would not say if we did.

    What we don't know

    • The date above is the newest review we hold, which is not necessarily the newest that exists — we hold a large share of Google's reviews, not all of them.
    • We do not verify licences, insurance or bonding. Nothing here has been checked against a state licensing board.
    • We cannot tell you what an installation costs, and we hold nothing about the equipment they fit.
