I used Cosmic for my solar and glad that I did. Jose, who I dealt with was extremely knowledgeable and always answered every question I had. They were professional and fast and did a great job. Since my solar was complete I have also recommended 6 or 7 other friends to him, and all have been completely satisfied with their solar. Now 3 years later, I can still call Jose and he will answer any questions or concerns that I have . I highly recommend Cosmic Solar and Jose!!

Stellar Solar Company serving Valley Center, Pauma Valley and more! Jose Duran is fantastic, a highly knowledgeable representative of Cosmic Solar liaising with Sun Power for Solar solutions. Purchased 55 panels and they are true their word on solar output estimates in contract. Great Financing options too! Also purchased a pool thermal system for solar pool heating.

Cosmic Solar makes the process…
Cosmic Solar makes the process so easy and smooth. We reached out to Pey in late Jan, fully expecting the work to be delayed to much later this year due to the NEM 3.0 rush. But with the seamless coordinations between departments at Cosmic Solar our system already went PTO in early April. Ron from the roofing department was very efficient and gave us honest opinions (as well as competitive pricing) for our roof work. When a small issue occurred with the monitoring system Khi and his team helped us fix it within two days. Everyone we have spoken to is polite and professional, and it's a great experience overall. I wouldn't hesitate to recommend Cosmic Solar to neighbors and friends.

Let me start be noting that I’ve been a commercial industrial electrician, Foreman, and General Fireman for 30 years and am now an Electrical Inspector for the City.
That’s by way of saying I know a clean and proper installation when I see it.
Cosmic solar did an absolutely fantastic job for us with our project.
On time completion of every aspect, all members of their team we very communicative throughout the project, installation team did a great job and cleaned up at the end of every workday, and the start-up and commissioning tech was very professional and skilled.
In short a five star experience from our first meeting with Larry (our project advisor) all the way through to receiving our Permission to Operate from SDG&E!
If you are considering solar, these guys should be your first call!

Great folks, great customer service,…
Great folks, great customer service, and great prices! Larry Schmidt really took care of me on my initial system years ago, and when my needs grew, I went right back to expand my system. Can't say enough great things about the whole team (and my system)!

Cosmic Solar recently installed solar on our home, and we couldn't be happier with the results! Ken was our sales rep, and he was great to work with, as was everyone in the office. Ashley, Arlene, Pey, and Mary in the office, as well as the whole installation team were professional, polite, and hard working.

We contacted 5 different solar companies, and all the others were good, but Cosmic just seemed to have an edge over them in every respect.

If you want a great experience, and great solar, I strongly recommend using Cosmic Solar!

We were planning to get solar installed for a while. Finally, we went for it and made the April deadline before the net metering rules changed. Although, we would have done the installation regardless.

A big shout-out goes to Cosmic Solar for providing us with stellar service. Pey Shadzi is an incredible wealth of knowledge and knows everything solar. Pey provided us with the best solar options based on our needs and usage. He is honest, personable, and genuine. The entire team kept us informed every step of the way and paid attention to all details. The team at Cosmic Solar made our installation a seamless process.

Cosmic Solar is a reputable company. Our solar is up and running, and I am thrilled to be doing our part for the environment.

Several solar installation companies broached us, and some companies were pushy. That was not the case with Cosmic. Hands down, I recommend Cosmic Solar for all your solar needs. This company goes the extra mile, and the whole process was a positive experience. It’s clear that customer service is this company's priority. Thank you to the team, Pey, Mary, Ashley, Hector, and Witchy!

For the past two years…
For the past two years I've been solicited by multiple solar companies none of which convinced me to do the install. At the recommendation of a friend, I decided to try Cosmic Solar. From day one they have been very attentive to my questions and easily to reach by phone. I just got my system energized yesterday and will be monitoring its performance. Based on my experience with Cosmic Solar I strongly recommend this company.

I was referred to Cosmic Solar by 2 of my friends. Ken is the consultant that came to the house and gave us a proposal. There was no pressure from him. He was knowledgeable. polite and very helpful with our questions. I actually added 2 more panels than his original proposal. I felt he was honest with what he told me and recommended. I have contacted him about a few things since they put in my panels and he was prompt with a reply. The crew put up my 12 panels in one day. I would recommend Cosmic Solar and definitely Ken D as the person to work with.
