We had been putting off any solar options for our house for quite sometime. Our PG&E bills had been crushing our finances for many years. So after being sick and tired of being sick and tired we finally contacted SIG…SIG was immediately friendly and helped explaining the process. We were quickly funded and our install was scheduled. The installation was seemingly painless and the switch was flipped. Within a short time our PG&E nightmares faded. Everyday we leave for work the big beautiful sun fills our Tesla PowerWalls with juice.After the install the huge energy bills stopped. SIG also continued to check our system periodically to make sure everything is running properly. As the homeowner we are also able to check the system through the Tesla App SIG helped us set up on our phones.I typically don’t write reviews, but this one I had to. THANK YOU, SIG for your efforts in providing a quality service to our family.David MullinsOakdale Ca.
All the way from the beginning of the process with Josh Clark as our sales guy to the finished installation, Everyone on the crew were really great people. Very friendly site check crew and install crew. Super efficient workers and had my system running in one day. I am in the construction industry and their work is very clean and professional. I’ve already recommended SIG to 3 people. Josh Clark is very good with his communication and I always felt ”in the loop” during the process!
Rylan did a wonderful job of helping us figure out what our needs were. He also was a great help for us in deciding what was the best and most cost effective option was for our solar installation. Aron, Paul and their construction crews completed the ground mount structure, solar panels and Tesla Powerwall 3 installations in a very professional and clean manner. The office staff kept me informed in a timely manner of when the crews would be working on our project. Rylan was also always able to answer my questions during and after the completion of the project. The SIG company this wonderful installation at the end of the 2025 year when everyone wanted solar systems installed because of tax credit going away. I'm so happy we decided to have them install our solar system.
If you need solar panels and batteries installed or add more to your system i 1000% recommend you give SIG solar a call. Tony one of my co-workers told me about this company and put me in contact with Josh Clark. It was an awesome experience working with Josh Clark, he was never pushing me to just go ahead and sign rather had all the information i asked for and if he didn’t he would find out and let me know. It was a really smooth process from start to finish. I was not home on the day of the install but my wife was and she told me that everyone in the crew was really respectful and professional. They came to my house on a Thursday 8am and completed the hole install that day 23 panels, 1 battery, inverter, and smart electrical panel. The whole crew cleaned up after themselves no boxes, trash, nails, screws, nothing left behind they cleaned everything. All the guys did an amazing job im really happy with my install no issues whatsoever. One thing i did request Josh Clark was that I didn’t want no conduit whatsoever to be shown/ran outside of my house or roof, his response NO PROBLEM. Thanks again SIG SOLAR and JOSH CLARK.
Im very happy with my new solar! Im glad I went with SIG! Josh Clark was great to work with, he helped me understand the process and answered all my questions, was really patient and responsive (and I had a lot of off the wall questions). The Installation crew was great! Got the project done really fast and the quality of work is obvious compared to the other houses in my neighborhood with solar panels. Super clean job. Looks great. Thank you so much!
