Off-grid solar technology company OPES Solutions has received the "Best Quality Supplier" award from ENGIE, the world's largest independent energy producer. In addition to yield, ENGIE judges were impressed by an exceptionally low failure rate and feedback from Original Equipment Manufacturers and users alike. Of the 43 suppliers reviewed, OPES Solutions was one of only two that met each of ENGIE’s rigorous assessment criteria. The award aims to encourage suppliers to continuously improve the quality of their products and components.

Quality is key for energy access systems

OPES Solutions supplies ENGIE with off-grid solar modules for solar home systems to provide off-grid communities with access to energy. Solar panels are often the only source of electricity in rural areas with little or no access to local servicing and maintenance, leaving no room for failure. Reliability is paramount. “We place a lot of emphasis on creating quality products at an affordable cost to make basic energy available for all”, says Peggy Cheng, Head of Upstream Supply Chain at ENGIE Energy Access. Founder and CEO of OPES Solutions Robert Händel adds that “off-grid solar technology should improve life in off-grid regions without unnecessarily burdening the environment or the people involved in its production. That is why we are committed to durable, low-emission products, efficiency, and fair working conditions”.

Figures indicate continuous improvement

The ENGIE reward recognizes the steady increase of audited factory yield rates at OPES Solutions. With its ISO14001-certified environmental management, the company has also been able to make continuous improvements across multiple efficiency indicators. The company reduced energy use per kWp solar module unit during production by 31% between 2018 and mid-2020, and water usage by 40% during the same period.
