I had 15 REC solar panels with Enphase Microinverters and a 15kWh Franklin battery installed by Custom Solar in July 2025, and I could not have been more pleased with my entire experience. After an initial enquiry to get some information, John Wagner called me and spent an hour on the phone with me describing their services and answering my questions in detail. He then sent me several models for my future installation in order to assess various options and configurations. After a subsequent visit to make sure that my house could accommodate the chosen configuration, the installation was scheduled rapidly. The team who installed the panels and the battery was professional, courteous, and did a terrific job answering my questions and cleaning up the site afterwards. Custom Solar worked with me to make sure I understood how to use the Enphase and Franklin Apps that control the system, and have done a terrific job since then following up on maintenance and making sure that the system met my expectations. Excellent communication, transparency, technical competence, thorough help to complete the required paperwork with Georgia Power and professionalism: I cannot recommend Custom Solar enough!

They certainly put the custom in Custom Solar Solutions. They were able to figure out how to move all of the panels I needed onto my detached garage. They explained the pros and cons of everything to include location of panels, batteries and controllers. Extremely knowledgeable on all things solar and battery storage. Krishan and Maddie did a great job installing a level 2 charger in my garage going up through the ceiling and wall from the basement creating a minimally invasive and clean install - looks just like the brochure instead I’d metal tubing all over the place. Kareem and John really know the Enphase system.

We had CSS add battery to our existing roof top solar panel system. A primary objective was to have power when the grid goes down. A second objective was to have greater grid independence than we were getting with panels alone. I kind of knew what I needed, but not really. Unlike a competing solar service we had approached about the job, the very knowledgeable John at CSS was much more clear about what components and upgrades of our existing system were necessary to meet these objectives. The install was in the spring. It's now the fall. We've sailed right through a handful of grid--down events, mostly during bad weather, with lights and fridge and internet and tv and fans and even AC. (Count me among the fans of the built-in Enphase Storm Guard function). We're using more of the power generated on our roof, too, rather than feeding it back to the grid. We get a lot of days of 98% grid independence now, which feels nice. We also feel very well-insulated from the never ending Georgia Power rate increase regime, which Georgia voters could control if they voted properly, but don't. Finally, and trust me because I've been through a few, we're very fortunate to have a solar provider like CSS in the area offering excellent design AND service/installation. Unfortunately, that's not as common as it should be. CSS talks and walks.
