We installed solar panels with Stateline Solar in mid June 2022. Our very first electric bill was down to the minimum payment after only 2 weeks of accumulating solar energy credits! The sales and installation people at Stateline Solar were all professional, knowledgeable, and provided quality installation of our panels. If you've done your research and are ready to install solar, consider Stateline Solar. We're happy we did.

I loved my experience with Stateline Solar from beginning to end - they know how to build great relationships and I'll stand by that. They walked me through every step, from the initial consultation, to signing the paperwork, to installation and connection to the local service (net metering), to how to monitor my system through the app. Each person along the way was great! Would definitely recommend!
