Solar Installation Project

If your are looking at getting a solar system installed I highly recommend you get at least three quotes. But if you don’t include Thirsty Lakes in one of your quotes you are making a huge mistake. Jeff at Thirsty Lakes is very conservative when he is putting your quote together, and he will develop a system that best fits your home’s needs. Jeff developed a system that hopefully will be revenue neutral after 12 months. He will not try and sell you a system that is more than what you need. He is very good at explaining what he thinks you need for a system and why. I would strongly recommend you have Jeff give you a quote before you have a system installed. My wife and I are very satisfied customer, I hope you will be able to join us. Thank you

Solar is so much easier than we thought

Jeff and Derek did an excellent job. It was so easy and non intrusive! Clean and efficient, we are thrilled tho my husband has developed a new obsession—checking his phone for how much power we are generating.

Jeff Aldworth | Belgrade, MT | 11/07/2025

I was very happy with the quality of Thirsty Lake Solar's installation, getting all the needed permits and applications with the power company and the explanations and instructions on the workings and maintenance of the system. I would recommend Thirsty Lake to anyone interested in investing in Solar.

Celia Swain | Augusta, MT | 07/26/2025

So Happy

Working with ThirstyLake Solar was a pleasure. Jeff is knowledgeable, organized and communicative. Follow through was terrific as well. He notified State and local power company inspectors and they came promptly.

Greg Young | Bozeman, MT | 07/15/2024

Jeff and Danny did a great job from start to finish. Highly competent and friendly, which was a nice combination. They explained the net metering and all the things I needed to know in a way that I could easily comprehend. Highly recommend!

Jeff and his team were great to work with. They were very forthcoming about the process, pricing and installation. Jeff was quite thorough explaining the design and outcome and we would work with him again.

Shaida residence | Bozeman, MT | 06/13/2023

Fantastic solar installation

Jeff designed and and completed the work on our system with little fuss and with super-competent skills. He set us up with the app that monitors energy production. Exciting to see those megawatts produced. I highly recommend Thirsty Lake Solar.

Ise | Kila, MT | 08/18/2022

Quality no-hassle install of PV system

Jeff and team arrived when they said they would, got the job done quickly, and we were up and running within a few days. Nice to see the grid-tied meter running backwards for a change!

Hans and Kristina | Bozeman, MT | 07/24/2022

Most wonderful experience ever

Planning, paper work filing, permit application, installation, and inspection by the city, everything was done absolutely professionally and with thoughtfulness. Jeff is an absolute pro, always on time and delivers above expectations. We already recommended his services to multiple friends.

Timberline Creek customer | Bozeman, MT | 06/10/2022

honest, reliable, hard-working

What more can you ask for? Jeff keeps his word and works hard to install your system as soon as possible.

Bundy & Jane | Bozeman, MT | 06/05/2022

GREAT JOB

We really appreciate Jeff's and Thirsty Lake's attention to detail. The install went amazingly fast, much faster than we thought it would. The workmanship and quality are top notch !! The entire installation and activation went super smoothly. Much appreciated effort and quality of work. Thanks Jeff !!

Brian Blicker | Bozeman, MT | 04/14/2022

Great Experience

Jeff was great to work with. Install was completed quickly and for proposed price. Highly recommended.

Jon Steele | Bozeman, MT | 03/10/2022

5 Stars

I was very pleased with the work that Jeff and Thirsty Lakes Solar did on the installation of a solar panel system. Jeff spent a lot of time designing the system and quoted on numerous options for me to consider. He followed through with the schedule he provided and maintained a professional demeanor throughout the project. I would highly recommend Thirsty Lakes Solar to anyone.

Steve Sweeney | Bozeman, MT | 01/14/2022

Skilled and competent solar installation

Jeff was prompt and thorough and completed our solar PV project on budget and ahead of schedule. In addition to being an experienced solar installer Jeff is a licensed electrician, so customers can be confident in his work.

Bob Gresswell | Bozeman, MT | 01/01/2022

Couldn't ask for more...

Jeff was great to work with: competent, diligent, and affable.

Bryher Herak | Basin, MT | 12/03/2021

Jeff was easy to work with and handled all of the details with Northwest Energy. He and his team did a great job. I am impressed with his knowledge and with his quick response in getting our system installed and up and running. I would highly recommend him for anyone just beginning their solar journey.

Purcells | Ennis, MT | 11/29/2021

Jeff at Thirsty Lake Solar was so easy to work with! Great communication and timely installation which made the potentially daunting process a breeze. We are very happy with our new solar system. Highly recommend Thirsty Lake Solar!

Brendan | Bozeman, MT | 11/28/2021

Thirsty Lake has installed several PV systems on our street - thought that was a good recommendation and were not disappointed. The install is very neat and is working well so far.

GMS | Belgrade, MT | 11/11/2021

Fast, professional, great prices

Walked us through from estimate to helping with DEQ loan follow up paperwork. Friendly, patient, and professional all the way. Ask for info on snow guards before install if putting panels over high traffic area.

Joe & Jenny | Glendive, MT | 11/04/2021

First rate solar PV installer

Jeff and his team at Thirsty Lake Solar have been a great pleasure to work with. I like the friendly, knowledgeable, helpful, small business type customer service I received from the initial consultation all the way through the finish of the install of the PV system on my residence. Communication was superb too. With my install the meter box and service panel were replaced and upgraded too and Jeff took care of this as well. He was very accommodating for some special requests I wanted done at the service panel. All of the electrical upgrades at the service panel and meter box were done very professionally by Jeff. And the same can be said for PV system too, from how the inverter and emt conduit was mounted and ran to the layout and install of the panels on the roof. If you are looking for a solar installer that prides themselves on quality, professional work that is knowledgeable and friendly in helping you build a system that is right for your application then I highly recommend using Thirsty Lake Solar.

Mark Austin | Belgrade, MT | 11/03/2021

Professional and Patient from Inquiry to Install

We installed two systems, one commercial, one residential and Jeff at Thirsty Lake Solar was helpful, professional, and patient throughout. Helped us walk through state loans and deal with paperwork before and after. Install only took 2 days; first to install the mounts, second the panels. Highly recommended.

Bruce and Sue Peterson | Glendive, MT | 10/31/2021

Great service and communication

We had a great experience with Thirsty Lake Solar and would highly recommend them. They were very committed to making sure we have a professionally installed quality product. Thirsty Lake started by doing a quick solar appraisal using a satellite image from Google Earth, answered our questions, and further explained the process. This was followed by a site assessment at no cost to us. The assessment showed us how many panels we'd need, how the panels would be arranged, and how this would probably affect our energy bill. Jeff, the owner, installer and electrician, was very informative, professional and helpful. Every step was thoroughly explained to us. Thirsty Lake installed an app that works with the system showing us how much energy is being produced and how well our system is working. After our system was installed, we got a call from Thirsty Lake Solar wondering if we had any questions or concerns. This was a 5 STAR EXPERIENCE. Thank you, Jeff and Thirsty Lake Solar.

Satisfied homeowner | Bozeman, MT | 10/03/2021

Great to work with

Jeff was very knowledgeable and got teh job done sooner than originally promised. It was nice working with the owner of a business who does the work himself (occasionally with an assistant) and takes pride in his work.

Short summary of Thirsty Lake Solar

We are renovating our house and wanted solar panels. These is our first time with solar panels. We selected Thirsty Lake Solar because we saw their sign up on a recent install. The process with Thirsty Lake was flawless. They were prompt, efficient, helpful with the paperwork with the energy company, install took about a day and a half on schedule, and we're really pleased that our panels are live and working. Really had a positive experience with Thirsty Lake Solar and they are easy to recommend.

Brian | Bozeman , MT | 06/30/2021

Top Notch

Simply great in every dimension: professional with great attention to detail, friendly, responsive and willing to provide expert guidance

MJ Williams homeowner | Basin, MT | 06/14/2021

good communications, excellent workmanship

I am very happy with my home solar installation. I chose Thirsty Lake because of the quality of their work on a large community project which Jeff installed here in Basin.

Noy Holland | 05/20/2021

sunny days ahead

Thirsty Lake Solar installed our first system about eight years ago, and added to the system this spring to bring to the max our electric coop will allow. We came back to Thirsty Lake because of their stellar customer service, their promptness in planning and answering questions, their quiet professionalism over the course of the installation process, and because our original system has worked well for years. We've had absolutely no problems with our first array, and Jeff has generously answered my questions about obliquely related issues like co-op demand charges and state renewable energy policy. We live in a high-wind area and the bracing for the panels has given us no worries. We're happy with our system!

Keith Poe | Trego, MT | 05/04/2021

Great service, fast install

Awesome experience, professional install done right and on time

Madisons in Bozeman | Bozeman | 05/01/2021

Really happy

Jeff is a total pro who guides novices through the installation process like a good friend. When we have more roof space, we will be calling Thirsty Lake again!

Tim | Bozeman, MT | 12/10/2020

Great experience!

Jeff with Thirsty Lake installed a grid tied system on our home and made the process smooth and easy. He handled permitting and dealing with the city, had great communication in keeping us updated, showed up when he said he would, and did a very professional install. I would definitely recommend or use him again. Thanks Jeff!

Graham | 12/08/2020

Great Experience!

Jeff was a pleasure to work with throughout the entire process, from the initial site visit through final install. He is very experienced and professional and we would highly recommend him to anyone looking to install solar.

Bob and Beth | Bozeman, MT | 10/10/2020

So glad we found Thirsty Lake Solar

We heard about Thirsty Lake from a neighbor who recently had solar panels installed on his house. He sang praises for Jeff Wongstrom, and highly recommended him. I had already spoken with one other solar company which I liked, but I thought it wouldn’t be a bad idea to get a second opinion. I’m so glad we did! Not only was Jeff less expensive than the first company, he also gave us a bigger inverter which meant we could easily add more solar panels at a future date. His is a hands on kind of company, and he does the work himself with an assistant. He showed up when he said he would, and always left the work site clean. He explained about the solar discounts we could get from the federal and state governments. And when the system was installed, he gave us a tutorial on how it worked. But I think the most important thing about Jeff is that we trust him. He knows his stuff, and we never worried that we were getting an inferior product. He is friendly and open, and I know if we ever have any questions, he will be available to answer them. If you are considering installing solar energy on your home, we highly recommend you talk with Jeff Wongstrom of Thirsty Lake Solar. You won’t be disappointed.

mtraffbzn | BOZEMAN, MT | 08/28/2020

Working with Jeff

We chose Thirsty Lake Solar because they offered us a completely integrated solar power option. Jeff Wongstrom met with us initially to get a thorough understanding of our needs and at our next meeting returned with a complete set of plans and cost options. He worked independently from us- scheduling his time to work around the rest of the construction of our new house and when we were ready, so was he. The system works great, we have had no problems and we are currently in a position of having energy credit as we move into the the darker time of year.

Loving Our Solar Power | 08/05/2020

Expert Advice and Installation

Jeff Wongstrom took time to learn our needs and he communicated the intricacies of solar power and the installation process extremely effectively. Jeff kept every appointment he scheduled during installation and helped with permits and dealing with our local power company. Our project with Jeff was the best.

David Yaak Valley, Mt. | 08/03/2020

After The First Year Review

Jeff was the original solar installer of our off-grid homes solar system in the extreme Northwest corner of Montana. The original owners had strongly suggested using him and Thirsty Lake Solar should we want to do any upgrades. Jeff was outstanding from the first contact, to the end of the project. This was a big bonus for someone that has no business trying to attempt building anything, especially a solar system! I basically told him what we wanted to accomplish with an upgrade and Jeff put together a system that would meet/exceed those laymen requests. Along with the extra solar gathering ability of the new panels, and the larger storage capacity of the new batteries, we have peace of mind that the system was built right, will work for many years to come, and that one of the best solar company’s did the project. He has been inducted as an honorary family member.

Mike | 08/02/2020

Best Solar Advisor and Installer

Jeff is an excellent solar energy expert. He keeps up to date on available products, is expert at designing systems that suit your needs, and highly skilled at installation and setup. We have a system that produces 67% of our energy needs which was designed and installed by Jeff quickly, efficiently and professionally.

John Ripley | Bozeman, MT | 08/01/2020

Thirsty Lake very accommodating to my changing schedule

Thirsty Lake was chosen for my initial installation. That process was very straight forward, professional and I was provided with the needed details to move quickly on the project. Due to a home remodel, I asked for assistance with a panel removal and replacement. Jeff was very accommodating and always a pleasure to work with him.

Norm | 08/01/2020

A good company to work with on solar systems

Thirsty Lake Solar was responsive to our solar questions, sent us information, gave a quote they honored and completed the work on scheduled.

MTBens | 07/30/2020

Thoroughly professional, honest, friendly

In this sparsely populated, rural corner of Montana, we weren't sure where we would find a solar installer with the expertise we could trust. Jeff at Thirsty Lake Solar was more than we hoped for. He is thoroughly knowledgeable. He came to the house and made a very detailed assessment of the situation with realistic projections and suggestions.Once he writes a proposal you can be guaranteed there will be no hidden or extra costs. Our system has been performing flawlessly in just the way that we expected.

Steven B. McCann | Gallatin Gateway, MT | 07/30/2020

Excellent

The entire process was smooth and professional. I recommend without reservation.

Solar customer | 07/25/2020

System producing energy as per pre installation quote.

Locally owned, polite, easy to deal with, offered on site evaluation. High quality components compared to similarly priced quote.

Dean C. | 06/11/2020

Effortless, high quality installation and system

Jeff made a very appropriate recommendation, got all the permissions, installed the system quickly and with no disturbance to us. Easy Peasy. We wanted to minimize the visual impact in our historic neighborhood and he found just the right panels. The system has been perfectly reliable and very efficient. We are completely satisfied and would recommend Jeff and Thirsty Lake Solar to anyone.

A year later

I have a small, off-grid cabin of about 600 ft/sq. I did not have a lot of experience with solar but wanted to use it for everything except heat, which was wood and propane. Jeff is as professional and efficient with his work as anyone I have dealt with...as his ratings indicate. I also impressed with his willingness to answer questions from time to time and provide me with all the necessary reference material that I need to educate myself. Now, a year later, I am even more impressed with how well the system is working and how little maintenance I have had to perform. I am also a lot more educated in using solar energy (although I have a lot to learn), thanks to Jeff taking the time to explain answers to questions and the written material he has sent me. I highly recommend that he be considered for any solar project that a home owner has.

Yorkie | 12/02/2016

Straight forward, efficient and reliable

This was one of the best experiences I have had with a contractor. Everything was as I was told it would be. Work was exceptional quality. Price was good, even a little less than we originally were told. Work was completed on time and system was operational in a very timely fashion. Work done and the installation are high quality and complement and blend well with our roof and structure.

sunnydays | 09/19/2016

Very Pleased!

Our solar is up and running and we couldn't be happier, we're excited to see the difference in our energy bill. Jeff and his crew were courteous, timely, neat, methodical and professional. Jeff took the time to explain everything and at the end each workday they cleaned up everything. They also kept the worksite neat during the day. We've had so many neighbors comment on how nice the solar looks and even had the architectural committee of our hoa tell us it looked great and that they worked so neatly and quitely, you didn't even realize they were there! We have recommended Thirsty Lake to everyone we have spoken with about the solar
