Clean Power Research (CPR) was a leading provider of cloud software solutions serving the clean energy industry. Founded in 1995, the company specialized in research, software, and data services that enabled utilities, solar developers, and energy agencies to make intelligent decisions about renewable energy resources, particularly solar. Key offerings included SolarAnywhere® for irradiance data, WattPlan® for distributed energy resource planning, and PowerClerk® for interconnection and incentive program management. In September 2021, Clean Power Research was acquired by PowerFactors, LLC, integrating its expertise and products into PowerFactors' broader asset performance management platform for renewable energy.
This location served as the primary center for Clean Power Research's software development, research, product management, sales, marketing, and corporate operations prior to its acquisition.
Situated in downtown Napa, the office provided a professional and collaborative environment designed to foster innovation in clean energy technology. Specific architectural highlights of the leased office space are not widely publicized.
Clean Power Research was known for its mission-driven work culture, emphasizing innovation, collaboration, technical expertise, and a commitment to advancing the renewable energy transition.
The Napa headquarters was instrumental in the development and growth of Clean Power Research's influential software products, establishing the company as a key player in solar energy analytics and utility solutions in North America.
While Clean Power Research's primary market focus was North America, its SolarAnywhere® irradiance data and API services had global coverage and were utilized by international customers for solar project planning, forecasting, and research. This provided a foundational global reach for its data products, supporting renewable energy initiatives worldwide. Post-acquisition, its technologies contribute to PowerFactors' expanded global offerings.
