Mr. Sun Solar Enterprises

Mr. Sun Solar Enterprises is a Portland-based solar contractor with over four decades of experience in the Pacific Northwest’s renewable energy sector. Founded in 1980 by John Patterson—an industry pioneer known as “Mr. Sun”—the company has installed more than 3,000 solar systems across residential and commercial properties. Mr. Sun Solar specializes in designing and installing photovoltaic (PV) systems for electricity generation as well as innovative solutions for solar water heating and pool heating.
The firm is recognized not only for its technical expertise but also for its commitment to advancing clean energy policy through legislative advocacy and public education initiatives. John Patterson himself invented the Sol-Reliant hot water system—a durable solution that has contributed to his reputation as an expert in the field—and continues to provide educational presentations worldwide on practical applications of renewable energy.
In 2012, Mr. Sun Solar was acquired by Neil Kelly Co., expanding their reach while maintaining their specialized focus on customer service and long-term reliability; many original installations from the early 1980s are reportedly still operational today. The company’s dedication extends beyond installations: they actively support clients throughout system lifecycles with maintenance services while promoting broader adoption of sustainable technologies within Oregon’s communities.
