Qcells is proud to announce we are the FIRST company to receive TÜV Rheinland certification confirming our tandem solar technology meets strict UL and IEC 61215 standards.
“Solar is already cutting energy costs and delivering reliable power to communities around the world, but imagine what this technology could do if it became even cheaper, more efficient, and faster,” says Fabian Fertig, Head of Tandem R&D for Qcells Germany. “Hitting these milestones means we are getting closer to bringing a product to market that is reliable, saves money, and works better.”
These certifications are among the industry’s toughest reliability tests.
Passing them means tandem solar technology is one big step closer to rooftops around the country.
