George Touloupas, Vice President of ESG and New Services at Intertek CEA, and Huatian Xu, Director of Technology and Quality, present the October 2025 results from the pv magazine test outdoor installations in Yinchuan, China, and Dammam, Saudi Arabia.
Irradiance and temperature conditions at the Yinchuan test installation site continued on a downward trend in October 2025. But this did not influence the performance or the ranking of the products. The Risen heterojunction product was removed from the installation for examination.
On Oct. 15, there was a power cut in Dammam, and the meteo and production data from this day have been removed from the results. At the test site in Dammam, high temperatures and strong irradiance conditions continued throughout the month, and there was little change in the performance of the modules installed there.
