OnSite Energy

Onsite Energy project

Great company to work with. Having built over 100 homes in Southwest Montana, we're a proud partner of Onsite Energy and give them the highest recommendation for solar design and install.

Happy Customer in Helena

I highly recommend working with Orion and OnSite Energy for your solar energy needs. Orion and his team made the entire process extremely easy and helped me understand any questions I had before, during, and after the install. He had cost estimates back to me within a day. The entire install of our 3.4 kW grid intertie system was done in a single day and we were up and running as soon as the power company installed the net meter. The panels are American made. The system has worked flawlessly over the last 5 1/2 years since it was installed and has met over 100% of our electricity needs during that time. I recommended Orion and Onsite Energy to my neighbor and he is also very satisfied with his system. When I buy an electric car and need more PV capacity I will definitely work with Orion and Onsite Energy again.

Roof mounted solar array

The process of selecting a solar installation contractor is relatively easy in our Bozeman, MT region. There is a good supply of qualified and enthusiastic providers. After meeting with several local solar representatives I chose to use Onsite Energy. Orion at Onsite proved to be a valuable and reliable resource during the original construction phase in 2015. He worked with our general contractor's electrician to install the components needed for our eventual roof mounted solar array installed in 2017. This enabled the final installation and City permitting process to flow very nicely while saving a substantial amount of time and money. Onsite Energy's business model is obviously a team centered effort. The entire process from initial sales consultation to net meter installation was a pleasurable one. Every team member involved in the project effort was professional and displayed outstanding customer service. It's always a pleasure to work with an organization where the product is competitive, state of the art, and the people involved are enjoyable, qualified and engaged. Sincerely, Mark Momberg

Excellent Company for both Small and large jobs

I have to say that Conor and his entire crew were THE most knowledgeable people regarding my specific needs for a new solar setup and installation. We got 3 solar estimates (where one was an extreme "hardsell" and the salesman was showing up at unexpected, uninvited times). Working with Onsite was the best experience. Onsite not only helped us pick the best setup for "our" specific needs, they explained every feature and process in layman's language. Installation was neat and clean and timely. We already have a very small, older system which Conor inspected and confirmed it was still in good working order, not trying to get us to spend unnecessary money. We really appreciated that. Nothing is better than saving lots of money on your energy bill but also helping the environment as well! I can't recommend OnSite Energy and a new solar system enough! You will not regret the decision!

Small grid tied system

Orion and his team at Onsite energy did an outstanding job bidding, coordinating, and installing our small grid tied system (2.8kwp). They were very attentive to our questions and responsive to our timing. Especially helpful was their handling of all the paperwork, including city permitting, electrical permits, and importantly tax credits. They even reduced the price slightly from the estimate since panel prices had gone down in the meantime! All of their site work is detail orientated and carefully done. Recently they provided us with a one-year summary of our system's production, and it showed that our production exceeded their estimate slightly (5%) and was exactly right for our net-metering to cancel out our yearly electric usage. They have also responded helpfully to our concerns about a large building going in next door (potential shading issues) free of charge. All in all a top-notch, highly skilled and well-run organization!

Up and running as promised...

Onsite Energy (Orion Thornton) provided excellent service at all stages of my project. Orion's personal approach at all stages of planning, preparation and installation insured a properly working system that to date has produced more than 1000 KW of power from the sun. Orion's personal approach, knowledge of the Solar Industry and partnership with Northwestern Energy made everything easy - he used my installation as a training event for local electricians and electrical apprentices interested in Solar Technology and proper installation procedures. I am very pleased with my system and can assure anyone the Orion will go the extra mile to answer questions, provide detailed estimates and supervise installation. Great job!

Highly recommend with no reservations!

Owner Orion Thornton was recommended by a few different sources. He had worked for Independent Power Systems in Bozeman for several years before striking out on his own. Orion accommodated a last minute, end-of year push by us, and wedged us in with many others who were trying to get in before the end of the calendar year, for obvious tax reasons. He was timely on quotes, accurate as could be, and responsive and clear to any questions we had. He communicated clearly, pro-actively, on installation schedule, work flow, etc. Orion also extended an opportunity to and encouraged us to obtain a soon to be available new-to-the-US inverter. He and the manufacturer lent us an interim-use inverter, switched in the new model later, and we are delighted to have a state of the art, latest generation inverter. Extra effort, proactive thinking and conscientiousness, communication really embody Orion and his company Onsite Energy.

Great Operation and Fair Pricing

I called a variety of solar companies in the Bozeman area and Onsite Energy was by far the best. They answered all of my questions and explained the pricing. Other companies didn't want to waste their time with a smaller project and didn't care to answer my questions. They are highly recommended.

PV Install

Orion gave us A1+ service, beginning with understanding PV systems, working through the electric utility regulations, and coordinating his installation with the new roof being applied at the same time. Further, the electrician that works with him is efficient and professional. Now that the system has been operating for about 9 months, I can report that it works perfectly and Orion's installation looks good. I could not be more pleased.

Bryce Maxell, Helena Montana

We had a wonderful experience with Orion Thornton and Onsite Energy in installing our 3.4 kW PV solar energy system on our house in Helena, Montana. Orion is incredibly knowledgeable about solar PV systems and the renewable energy field in general. He was very timely in all of his communications from the initial bid, to the contract for installation, to follow up communications on the meter installation. The installation went very smoothly, was fully completed in only a single day, and looks wonderful. I highly recommend Orion and Onsite Energy for all types of solar PV installations!
