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 husband and I got our solar put in February 2017, after much consideration. We did our research and Solar Harmonics was the best fit for us! They’re pricing is fantastic, they were easy to work with, great communication, and getting things installed quickly was a breeze. They were recommended to us by neighbors and we highly recommend them to anyone else!

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.

I have never posted a review on yelp before and generally don’t post reviews, although I find them incredibly useful when researching purchases.  But, I feel it’s worth my time to let other people know of my experience with Solar Harmonics compared to my experience with a couple of other companies.

First, if you are considering a solar panel project, I highly recommend Solar Harmonics. Solar Harmonics was professional, courteous, and was fantastic at keeping me updated about every step of the solar panel installation process.  All of my questions and issues were answered promptly and clearly and I really appreciated him working with me to determine if solar could be installed on my roof.

Prior to working with Solar Harmonics, I tried another local installer and they kept trying to sell me a lease even after I made it clear I did not want a lease (goodbye).   I then tried getting solar through a website where contractors submit competing bids and the customer can choose which bid to accept.  This was a nightmare.  I spent about four months of phone calls and emails with nothing getting done after selecting one of those bids.  I was lied to and misled and the price could have potentially nearly doubled after being told I needed a panel upgrade (another lie as Solar Harmonics inspected the panel and informed me no panel upgrade would be necessary).  After four months, I was never even sent a contract showing the actual price.  This was a year ago and I gave up after that.

Thankfully, I decided to try one more time and contacted Solar Harmonics.  The contrast in experience couldn’t be any more different from what I experienced previously.  There was no pushy selling.  Instead, he worked with me to determine if solar would work for me.  Communication was superb and the process was incredibly fast.
