Our certificates are your guarantee that German and international quality standards are being met. Regular independent inspections and our own internal quality management system ensure constant top quality for our solar modules.
 
Almost all asola quality modules have been approved by the German Technical Inspection Agency (TÜV) and are certified according to international requirements (IEC 61215, 61730 and UL 1703). Our own standards go beyond these requirements, exceeding the certification standards two or three fold.
