After shopping around for solar systems, I found Solar Harmonics on YELP, and based on reviews I decided to contact them, their response was fast and he  took the time to explain all the options available and financing options, Solar Harmonics’ team are quick at responding e mails or any questions. Crew did an amazing and clean job, they even painted all conduit pipes! I just provided paint for stucco, I would highly recommend Solar Harmonics!

My system was installed in March of 2018.  I wanted to see how things went with the system overall before posting a review.  And rain.  I wanted to go through some storms.  Spoiler alert:  No leaks.
Honestly?  Things went fine.  Solar Harmonics knew their stuff and was patient while I worked through the thousand questions that Internet research will inspire.  The planning, permitting, installation and turn-up went according to schedule, and when we finally went live, the system just worked.
Because I’d recently changed over to a ductless HVAC system, I knew that my future energy needs would differ from the past PG&E bills that their team used to make a solar capacity recommendation, and was therefore concerned.  I didn’t need to be — I think the sizing was perfect:    with enough left over to where a super-hot summer (or super-cloudy/smoky winter) won’t yield any surprises.
So, 10/10 would recommend Solar Harmonics.  In fact, I actually have recommended them already.

We chose Solar Harmonics as our installer due to their astonishing Diamond Certified Rating. Our sales consultant was very knowledgeable and straightforward in explaining the pros and cons of having solar at this time due to future electricity rate hikes we are expected to get by the end of the year. We want to take advantage to lock in on current rates than pay the future rates in kwh.

Solar Harmonics install team did an incredible job installing the 19 solar panels at 300w rating.  We also installed an Ev plug connection in our garage. They matched the paint color on the conduit to our trim color so it blends in so well we couldn’t tell there was an installed conduit.

I would recommend Solar Harmonics again and again.  We took less than 4 weeks to plan, install, and connect to the grid to start saving money on electricity. Thank you Solar Harmonics for making this all happen.

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.

We have been reviewing solar technology for several years and finally requested bids from several companies. We chose Solar Harmonics for several reasons, a track record of successful installations, the quality of offered solar panels, and a competitive price. The team answered all of our questions in a timely manner and were very knowledgeable about all the ins and outs solar installs and dealing with PG&E. The installation went off without any issues and we are very happy with the end to end system from panels to inverter to monitoring system. We highly recommend Solar Harmonics for solar installations.
