“We recently had a very big solar system installed by Quattro Solar . The work done was very professional, David was always very good about communication. I would recommend David to anyone that asked me !!”
-Cindy Lee, Fairfield
“I wanted to report that this month my PG&E bill was negative.  Thank you so much for a great job you did!”
-Jerry, Lafayette
“David was my contractor for our solar installation this summer. Most importantly, the work was high quality and the result has been beyond my expectations ($0 electric bill, with an electric car). David was reliable and communicative during installation, and was also an expert on available technologies as well as all the government red tape. Beyond my satisfaction with the work, I found David a kind and interesting person. Although that is largely irrelevant to my experience as a consumer, it did make the entire process easier and was a nice ‘bonus’ overall. I would recommend him to anyone.”

“David Quattro was the Lead for the installation of my 2kW PV system in Petaluma, CA.  He ran a volunteer crew (6 at times, including myself all with different schedules and skill levels).  He tirelessly spent 3 long weekends at my home to complete the project. 

David spent extra time and care on the aesthetics of the entire system and especially the metal conduit routing along the exterior of the home from the junction box to the main switch.  I truly think that this system looks beautiful and will stand the test of time.  I am grateful that David spent so much attention to detail and follow through on completing this project.” – Dan Berger, Petaluma      


David always returned our calls, explained processes clearly, followed up on any schedule changes, outlined his work, stuck to a timeline/schedule, showed up on time and always cleaned up after his work day.  My husband was also pleased that David’s explanation of the process with the City of Oakland and then PG&E was clearly outlined so that there were no unpleasant surprises and that David took care of the entire job from start to finish.  We both noted that David takes pride in his workmanship and presents a level of ownership that is rare and a joy to experience.  I would like to add that what we also like about the system David installed for us is that each panel has its own inverter so that if a panel fails, the system is not down but continues to generate energy.  We feel very satisfied, comfortable and confident with our whole experience working with David and our new solar system.  We would highly recommend Quattro Solar to anyone thinking of going solar for their home.”"From the time that David came to our house, he listened to us and answered all our questions.  His explanations were clear and he never pushed us to go larger or with anything that we might have been uncomfortable with.  He came up with a system that would help us save money by removing us from the 2nd, 3rd, an 4th tiers of PG&E’s price rate for our energy usage.  He provided options and he let us decide. -Bill and Charlene, Oakland  

“A different solar company saw the inverter running, and told me everything was OK.  It wasn’t. I’ve been harvesting 50% of my solar for about one year.  Thanks to Quattro Solar we are back on track at 100%. I also appreciated a timely, efficient appointment.  I called on a Monday, he showed up that day, quickly and correctly diagnosed my problem, ordered the part and we were done.  There’s nothing better than a qualified solar expert to service your system. Thanks David and Quattro Solar.”

“Quattro Solar is awesome!
David provided me with a thorough explanation of each step of the process.  His bid was very competitive and the installation went very smoothly.  David obviously loves his work and keeps up on the latest technology.  I am now enjoying very minimal PG&E bills.  I have also referred Quattro Solar to my son-in-law and they are happy with their system as well!

I highly recommend Quattro solar for your solar installation.”
