Run on Sun

Run on Sun is a Pasadena-based solar energy company specializing in high-quality photovoltaic (PV) and storage system installations for both residential and commercial clients throughout the greater Los Angeles area. Founded in 2006 by a team of entrepreneurs, engineers, and business professionals—including CEO Jim Jenal—the company was established to address shortcomings observed in other solar providers, such as poor engineering practices and inadequate customer service.
A key differentiator for Run on Sun is its commitment to technical excellence: all three principals are certified by the North American Board of Certified Energy Practitioners (NABCEP), which sets them apart as industry leaders in Southern California. Their approach emphasizes honest communication with clients—from initial site evaluation through proposal development—ensuring that each system is properly engineered for long-term performance rather than simply maximizing sales.
Run on Sun manages every aspect of the installation process internally: from rebate reservations to permitting, utility interconnections, inspections, and ongoing maintenance. Their mission-driven philosophy prioritizes transparency and customer satisfaction over volume sales targets. The company has been recognized for its integrity-driven business model and has contributed thought leadership to major media outlets regarding solar policy issues.
