We had a solar battery backup system installed and Ken and his staff were helpful and professional throughout the entire process. Ken provided a wealth of information, helping us make an informed decision — he really knows his business. His installation crew was extremely professional and we appreciated their attention to detail. The installation was beautiful. From our initial consult through completion, the job was performed beyond our expectations. We couldn't be happier.

Cosmic Solar demonstrates incredible partnership and customer advocacy! From initial quote, through contract, permit approvals, rebate applications, system installation, provisioning and effective issue resolution, Cosmic has earned my thanks, trust and respect. I have been impressed with their recommendations, teamwork, responsiveness, and attention to detail. I rarely spend the time to write reviews, however it's my privilege to do so for Ken, Pey, Ashley, Mary and their very capable extended team. HIGHLY RECOMMENDED!

Cosmic solar was awesome to work with. They’re super organized and everything in our project went so quickly! They installed the panels in 4 hours!! And the panels look super sleek and cool.

Everything with the city went perfectly and the office took care of everything to help us get our rebates. Mary and Ashley kept us informed each step of the way and were so detailed in making sure it was all perfect. We signed on with Ken and he was very knowledgeable, professional, and kind. Everything he said they would do, they did, and to the highest quality.

I highly recommend this organization and working with Ken. Thank you to the wonderful team at Cosmic Solar!

I can not emphasize enough how amazing Cosmic Solar is from Pey, Khi, to Javier. The company goes above and beyond in service and products. I have been working with Cosmic now for over 5 years for my Solar and battery needs. I have been so impressed with all that they’ve done that I’ve convinced several of my neighbors to work with them for their solar products and installations. I recommend anyone looking for solar and batteries to reach out to them immediately, you will not be disappointed!

We cannot thank Cosmic Solar enough. We applied to get solar in the last 6 months of the 30% credit in 2025. They were super busy but we couldn't tell. Thier customer service is amazing. From starting our project with Jose and Pey, to the crew who installed our panels, to our technician Johnny who hooked up our battery, and even the office manager Mary and the scheduler Ashley everyone was so nice and guided us through the project from start to finish. If Ashley or Mary told us that the installation crew was going to be there at 7:45am then I knew they would be at my door greeting me and introducing themselves at 7:45am. They were so easy to work with and we knew exact what to expect and when. They also did all the permits with the city and sdg&e. Everything ran seemlessly. They made the whole process so easy for me, I was able to continue my business from home without a hitch. Thank you Cosmic Solar!
And I especially loved when SDG&E sent me a "you saved $63 on your bill this week" and we were only up and running like 3 days! Haha

Cosmic Solar & Roofing came highly recommended to me by my best friend of over 50 years. Many of his family members have also used Cosmic!

I'm really glad I took his advice after my first full year with the system. If you are serious about getting solar, I highly recommend that you add them to your due diligence quote list. We re-roofed with their contractor (Davalos Roofing. Fantastic work. Great bunch of guys!) along with it. It was my choice, not pushed on me. My roof was 20yrs old, and I wanted to start the solar on a new roof in an all in one package. Everyone listened to what I was looking for and made it happen. Everything came out great. We've had no issues, and have produced slightly more power than the estimate. Your mileage may vary.

These guys are the real deal in the San Diego area!
