    ★★★★★

    I found out about SIG when I used a neighborhood forum to see who people recommended. The most important thing to us was that they were local and handled everything in house. We met with Josh Clark and he was so knowledgeable and patient in explaining everything to our satisfaction. He made himself always available for our numerous questions and concerns.

His ability to explain complex technical details in an easy-to-understand manner has also been instrumental in helping customers make informed decisions about their solar energy investments.

    We used SIG for our new solar system on our house. We met Josh Clark, who was referred by our neighbor. Josh took the time to explain the process and answered our questions. He stayed in touch from beginning to end, which included an excellent job of clean up and getting us connected to their solar systems. The crew did an awesome job also, which included one of the owners of SIG coming to visit us to make sure we were happy. We would highly recommend SIG and Josh Clark if you’re considering putting up a new solar system or upgrading your current system.

    Had an amazing experience with SIG! they are the Best ! They made sure everything went smoothly and I understood what everything was and what it costed so I never had to guess if it was a good deal or not. Josh Clark was the absolute BEST person to talk to about getting switched over. He knows solar inside and out and always makes sure you understand and know exactly what’s going on. I would /will recommend SIG solar to anybody and everybody that wants to switch and save money ! 10/10. Experience. Nobody would be disappointed!

    We used SIG Solar when they put a new solar system on our last house and the crew did an AMAZING job; therefore, it was a no-brainer when we bought our new house and it needed solar put on it. We would NEVER use any other solar company! Josh, the Solar Dude, with SIG Solar is so extremely knowledgeable and honest and there for you at any moment when you need him or just have questions, he’s very prompt! The crew that came to the house were very friendly, cleaned up well after their selves and were extremely meticulous in their work…Really great job!
