    It began with a sudden urge to invest in renewable energy in our new home, and it resulted in a seamless process where I was happy with the result before the work had even begun.

    Our salesman, Garrett H., was very thorough from the first moment I had reached out to him. He had reached out nearly weekly giving updates on the process prior and during the project. (The project took a few months from start to finish - including a new roof.) Garrett still reaches out periodically to ensure everything is going well and that I am still satisfied with my system.

    The amount of time, attention to detail, and providing a proper load calculation is what sealed the deal. Many salesman can be pushy, but Garrett had given all the details plain as day with such energy that you could see he is passionate about solar energy, his career, and his product.

    In the end, I had received everything I could ask for from panel location to aesthetics while maintaining 100% energy offset.

    The few times I had reached out to their general customer service with questions, I had quickly received answers. (I.e. obtaining further product information to implement into my home automation system)

    Overall, I am beyond pleased with the process, the product, and the result. I look forward to incorporating a battery backup in the future, and will gladly repeat the process with both Garrett and SunnyMac.

    I had the best salesperson his name was Garrett Hessinger. I saw his name on Facebook and he wanted to help people go solar. I thought let’s give him a chance, and he was the best salesman ever! Everything was explained very well and he was patient and caring. I signed with Sunnymac and everything went so smooth from the permits till the system started up. Anyone you deal with at Sunnymac is a class act and very professional. A friend of mine signed with another solar company a few weeks before I did and his still hasn’t passed inspection . My system has been up and running for 5 1/2 months and he can’t pass his inspection. All I can say is he should have used Sunnymac! Overall I’m very happy with the work that was done by Sunnymac

    SunnyMac made our experience very easy. They kept us updated throughout the entire process. Chris answered all our questions and made us very comfortable with our decision. Most importantly, the install looks great just like they said it would! Very happy to have gone solar with SunnyMac.
