I am a 64 year old home owner who worked for 30 years as an aircraft quality engineer. I have never written a review for any product or service, but I am compelled to do so for Solar Harmonics. The service was first class. Any and all emails were answered promptly, most in a matter of minutes. The job of installation was completed professionally with little or no intrusion into my lifestyle. The price for the job was extremely reasonable. Do not go with the big corporate solar installers. You will pay twice as much and get half the service for the same product. A special thank you to the owner of Solar Harmonics who was always there to help with any issues that I had. Don't think twice. Use Solar Harmonics as your solar installer.
