Schatz Energy Research Center

Off-Grid Solar Testing Lab

The integrating sphere is used to measure light output and quality.

Located on the Humboldt State University campus in Northern California, USA, the Schatz Energy Research Center is a research laboratory dedicated to bringing renewable energy and sustainable technology to communities around the globe, while helping train the next generation of engineers through our association with the Humboldt State Environmental Resources Engineering department. Founded in 1989 to explore hydrogen fuel cells, we have has expanded our activities to include bioenergy, smart grids, renewable energy feasibility studies, and off-grid solar products.

Off-Grid Solar Product Testing

The Schatz Center has been testing off-grid solar products since 2006, holding a partner role with Lawrence-Berkeley National Laboratory in the Lumina Project and acting as quality assurance technical lead on the International Finance Corporation/World Bank funded Lighting Global project. In that time, we have tested over 150 off-grid solar products and played a critical role in the development of International Electrotechnical Commission (IEC) Technical Specification 62257-9-5.

Our laboratory's accreditation certificate to conduct testing according to IEC/TS 62257-9-5* is issued by the ANSI-ASQ National Accreditation Board (ANAB). Using the Lighting Global Quality Assurance Protocols for Solar Home System Kits, we are also able to test most SHS kits up to approximately 100W. We are approved by Lighting Global to conduct all test types for pico-products and SHS kits, including the Quality Test Method, Associate Renewal testing, Accelerated Verification Method, Initial Screening Method, and Market Check Method. Our lab is able to test thirteen different products simultaneously. With over ten years of experience in off-grid product testing, we are uniquely equipped to test complex lighting technologies and implement new testing strategies.
