Michael R.
Harmon Solar did a fantastic job on our 10 kW system. The crew was professional, showed up on time every day, and left the site clean. We are already seeing our electric bills drop significantly.
Jennifer L.
As a second-time customer, I can say Harmon continues to deliver. They expanded our existing system and added a Powerwall. The whole process from permit to inspection took about four weeks.
David K.
Good overall experience. The sales process was straightforward without any high-pressure tactics. Installation was completed in two days. Only minor delay was waiting on the utility interconnection.
