Highly recommend Coldstream Solar and Greg!
Greg at Coldstream Solar was amazing—knowledgeable, honest, and helpful. He saved me from a bad vendor and guided me to the right solar solution. Couldn’t be happier!

Good Solution for Solar
We were very pleased with our overall experience with Cold Stream Solar. Luke was a professional salesperson, providing information and answering questions at the initial visit. Luke worked with us to find the best number of panels that suited our needs and our roof structure. He continued to respond to all our questions and was an active participant as we filed our application with our HOA. The installation went very smoothly. 2 electricians and 2 installers showed up, got to work and finished the installation in about 6 hours. When they needed more paint to cover the conduit, Evan went to the store and refilled the supply we had gotten. They cleaned up our yard of all debris and materials. We recommend this company over some of the others who provided quotes to us. There was no hard sell. With Coldstream having both a solar and roofing division, we feel comfortable they will provide any future service we need to the solar panel system or the roof.

Great Company
I recently hired Coldstream to do our roof and solar install. The company was great to work with from beginning to end. They were super knowledgeable during the quote process (I got 12 different quotes) and even helped me evaluate other quotes. They helped me evaluate specific panels and microinverters. They worked diligently with me, answering all of my questions while helping me to work with my HOA. They took care of all of the regulations with the city and state. It was a seemless process and I would recommend my team of Luke (sales), Evan (ops), Cliff (Master Electrician), and Logan (electrician) to anyone.

We are completely satisfied with the entire group that we have worked with the Coldstream Solar. Luke, who came to our house and gave us a presentation of why we should use his company was a very classy young man and gave us factual information. We had questions for him, and he answered them to our satisfaction. Evan, who overall the installation is an incredible young man, and we were very pleased to have him as the foreman of our job.

outstanding roof and solar install and support
Greg, Evan, Cliff and the team put in quite a bit of work to coordinate a carefully considered solar setup, some home electrical work to get up to code, and a roof install. Having a solar and roofing company under one roof made communication and planning much easier for both projects. I appreciated that everybody was highly responsive with questions and document requests and helped get us set up for net metering, by dealing with the power company and the county.

sweet sweet nuclear fusion
We've been trying to harness energy from nuclear fusion for the past 80 years... turns out we already have a huge nuclear fusion reactor that can power all our needs, runs 24/7 non-stop, doesn't need any maintenance, and has enough fuel to keep running essentially forever. All we had to do is put these panels up to capture the energy it produces. Luke did a great job explaining all the stuff. Cliff and Logan did a great job installing the wiring for the system, and they even made sure there's plenty of silicone to seal around holes and stuff. Now my electricity is coming directly from energy released by the hydrogen fusion of a main sequence star. Stellar!

My wife and I are very impressed with the Coldstream Solar team and the solar energy system that they have installed in our home. Members of this team were very professional during every step of the process. It began with our introduction to Coldstream Solar and the excellent proposal presentation given by Luke (Sales Representative). Then Evan (Operations Manager) expertly performed the technical home visit to prepare for the installation. Finally on the big day a few weeks later, we watched the team of four men, led by Cliff (Master Electrician) and Logan (Electrician) install our new solar energy system. They obviously knew what they were doing and had our system running in about four to five hours. Each member of the team was courteous, respectful of our home, and always willing to answer our questions. During the time leading up to the system installation, Luke kept us up to date with the progress of the system design, obtaining the needed permits, interconnecting with our electric company, etc. He also took the time to give me a tour of the Coldstream Solar office/warehouse and to stop by our home on installation day to see how things were going. It’s so fun now to open the smart phone app on sunny days and see how much surplus electricity we are exporting to our electric company.

Solar Panel Installation
it was a pleasure doing business with Coldstream Solar for my solar installation. Luke had great insight to our needs, answering all the questions we had and was continually following up with us at every turn. Evan was on top of the game with all the paperwork including interactions with Duke energy. Cliff and Logan did a pre screen on our home for the installation and the installation only took one day. Their explanation of the system was excellent. I would highly recommend Coldstream Solar to anyone wanting/needing solar installations for their home.

Zero electricity bill, baby!
My husband an I met Luke at COLDSTREAM in 2023 and started our research and development phase of getting solar for our property. We were ready in the summer of 2024 and went over all the possible scenarios for where and how we would go about mounting not one, but two systems. We have a large property with outbuildings that also require energy. This was not the quick add to a house rooftop. The team at COLDSTREAM put their heads and years of expertise together to get us the best set up. Thank you to Evan and Cliff that delivered day of and made sure everything was set up and installed quickly and with the long trench getting dug around all the large shelf rocks in the path. And Luke that made sure we saw complete systems that would be similar to our own first hand. You cannot go wrong with this hard working and knowledgeable team. After two months of the system being activated we received our first $0.00 bills for the two systems. In the winter, can’t wait to see what the summer sun brings.
