Hands down the best solar system installer in SoCal – Was in the market for solar system for an office building and came across SunGreen. SunGreen stayed on top of the matters during the process, and took care of their customer like their own friend. All questions were answered efficiently and clearly before, during, and after the installation. The whole working process had been a blessing. Their team is professional and the installers they work with provide tip top quality work. Will recommend to my friends and definitely will do business with them again. Thumbs up for SunGreen!” – Lee920, commercial customer ( 6/16/2013)

ENERGY SAVINGS and 5-STAR Service – SunGreen installed our 50kW system in 2010. It has been a great investment with payback ahead of schedule. More importantly, everyone at SunGreen (top to bottom: sales, engineering, installers, and management) made it very easy for us. Our guests hardly noticed them here, and SunGreen took care of the permitting, approvals, design, engineering, etc. with very little effort on our part. Three years later, the system continues to work great, and SunGreen continues to support us.” – FX Wang, commercial customer ( 6/25/3013)

Great service and quick installation  – SunGreen Systems provided an excellent services to install 16.5 kW on my commercial roof. The installation was quick and professional, paperwork and licensing were all been taken cared well. Highly recommend.” – Tony, commercial customer ( 6/24/2013)

Professional and detail oriented – It has been 3 years since we worked with SunGreen. They are professional, patient, and detail oriented. They always response quickly and follow up tightly.” – Discovery, commercial customer ( 6/20/2013)




“Paul (salesman) could not have been more thorough with his presentation. He took the time to answer all my questions and showed me all the calculations as to why solar would work for me. His original proposal, before reviewing all my electric bills, came out estimating 4 panels more than the more thorough proposal. Instead of staying with the original plan like most salesmen would do(make more commission) he saved me 4 panels and thousands of dollars. This cut my payoff time by several months! The crew was very friendly. They set me up with a portal so I can track my production on a daily basis. Bottom line . . . great company with knowledgeable salespeople, efficient and pleasant installers for a great value.” – Guy D., Valencia, residential customer (Yelp 6/18/2015)

“I chose SunGreen Systems for their high quality of equipment and services. I highly recommend the energy storage system to provide electricity ... And SunGreen has the cutting edge technology and best quality of solar batteries.” – JCC10680, residential customer ( 2/14/2015)

“I am an Engineer. From start to finish of our home solar installation it has been very clear that SunGreen knows what they are doing. They are polite, professional, and very easy to deal with. Our electric bills have gone down as much as was promised! Also they installed better equipment at a lower price than anyone else I got bids from.” – HelmetFire, residential customer ( 5/30/2014)

Thank You SunGreen – Normally I do not write reviews but after deciding to go with Solar power we obtained 4 quotes and eventually selected SunGreen to perform the work. They were professional, courteous, informative and efficient during the quoting process and during the installation. They did everything they said they would do and did it well! We could not be more pleased with SunGreen and gladly recommend them to anyone looking to save money on their electric bills.” – TeeTime, residential customer ( 10/16/2013)

“I would like to take this opportunity to express my thanks to your company and staff for the work and installation you provided me and my family. You are to be commended for the excellent quality of work and the prompt and efficient service you and your staff provide.

Your professional courtesy and expediency and the quality of your services are something rare today in a world that sometimes forgets the human side of a business relationship.” – Pedro B., residential customer ( 10/3/2013)

Best solar company in town - We installed solar by SunGreen since September 2009. After solar, we are only paying a dollar per month. As of today, the solar system is still producing enough electricity to power our house as promised by SunGreen. Their sales representative contacts us every now and then to check out whether we have any issue with our system. They are very professional and responsible. I already recommended them to all my friends and neighbors.” – Sayaka, residential customer ( 6/13/2013)

Satisfied Customer - I researched many solar systems and installers before choosing SunGreen. My installation concerns were our Spanish tile roof in one area and penetrating a flat roof in another potential solar panel area. I hate roof leaks! Space for panels was limited so an efficient system was important. The process, from proposal to permitting to scheduling to installation to handling the rebates/incentives, was handled in a professional manner. After-sale service and monitoring has been great. I get monthly summaries emailed to me and a phone call if anything in the system is not performing as inspected. I keep looking for more space to expand my system!

Extremely friendly and highly professional people, they explained everything clearly without being pushy, their price is very competitive too. After we agree on the terms, installation was very fast. They also help us in getting our rebate quick.” – Sr Deacon, residential customer ( 8/22/2014)
