The Stellar Solar Team

With over a decade installing residential and commercial solar, Stellar Solar is one of the oldest and most experienced solar energy companies now operating in San Diego – we specialized in solar before it was hot! Our contractor’s license has been active since 1998 and we put that expertise to work for you with over 600 San Diego residential solar panel installations, 40,000+ solar panels, and over 6 megawatts of commercial solar installed in California.

"We carry a C-10 contractor’s license, considered the gold standard for PV Solar Electric installation. Many other companies hold only a C-46 plumbing license (for solar hot water installer). We are also a Better Business Bureau accredited member and hold an A+ rating."

Stellar Solar is wholly-owned, managed and operated by the experienced team below. We concentrate our residential business here in San Diego and have the flexibility to make decisions in our clients’ best interests, quickly and effectively. We run a lean business with low overhead that enables us to offer the lowest priced solar in San Diego.

Our Energy Consultants are the best and the brightest in the industry and strive to make the process of going solar easy and educational, with no high-pressure sales pitches.

Walt Virack, Operations Manager

When Kent told Walt about the explosive growth at Stellar and offered him an opportunity to be a part of it, he jumped at the chance. Walt had this to say about his decision to join Stellar Solar, “While San Diego is crowded with solar installers, Stellar has what many of them don’t, longevity, a very experienced team, a good mix of residential and commercial projects, and solid long term growth prospects. Those attributes made my decision an easy one.”

Brian Nagel

Brian Nagel, Energy Consultant

A Graduate of Iowa State University with a degree in Community and Regional Planning, Brian truly wants to find the best option for each customer. His straightforward and educational approach to sales can likely be attributed to growing up in the midwest. He first began working in the solar industry to be a part of something progressive, important to the future and a benefit to everyone, with the understanding that even those who don't go solar themselves benefit from renewable energy. Brian feels he is both helping to solve a problem and opening people's minds every day.

In addition, Brian has worked for the largest residential solar installer in the country, as well as the smallest. From that experience he is confident that a local mid-size company like Stellar Solar offers the greatest flexibility in solar solutions and best customer service for the best price.
