Since we put up the solar we haven’t had a bill. Nothing! I love nothing! It’s my favorite price!


They did a fantastic job and worked well with our difficult roof.

These are professionals who contract to professionals. We are extremely pleased and would go back if we ever decided to go SOLAR.

Thank you for coming to PetersenDean

Since I started 35 years ago, we have fulfilled our mission of delivering world-class roofing and solar power systems at the best possible value for our customers. Now, more than ever, I believe that solar power should be accessible for all Americans. In fact, this year, an independent review of California Solar Initiative (CSI) data shows that for the last 12 months PetersenDean has achieved the most affordable solar installation price.

The Solar4America campaign is my concept to deliver transparency in solar pricing and drive down the costs of solar power. No “financial magic” or “accounting tricks”; Just a fair price and commitment to quality installation. We look forward to earning your business.

– Respectfully, Jim Petersen, Founder
