Trina Solar, a photovoltaic (PV) modules, solutions, and services provider, announced the company’s new Duo-Max module, a 72-cell frameless dual glass module (the PEG14 and PDG14 series), has received quality certifications, including the IEC61215, IEC 61730 and UL1703 standards from world-leading independent testing and certification organizations, UL and TUV Rheinland.
The Duo-Max module comprises two layers of 2.5mm thin heat-strengthened glass, which replace the conventional glass and back sheet structure. The Duo-Max module is a highly reliable and durable PV product that is able to maintain high standards of performance in harsh environments such as desert, tropical and mountain areas.
The Duo-Max products offers high levels of resistance to degradation caused by thermal cycling, moisture ingress, mechanical loading, micro-cracking, PID, module warping, UV aging, as well as corrosion from ammonia, acid, alkali, salt mist and sand abrasion. The Duo-Max module also meets UL’s Fire Class A safety standards.
Trina Solar is the first PV manufacturer to offer a product that meets the most stringent PID testing conditions of 1500V system voltage under relative humidity of 85% and a temperature of 85°C for 192 hours. It is not necessary to use system grounding for Duo-Max modules, which reduces installation costs.
The frameless Duo-Max module comes in 60-cell and 72-cell versions and is suitable for both utility scale power plants and Distributed Generation PV systems. Both the 60-cell and 72-cell frameless dual glass module products carry a 30-year linear warranty with a maximum 0.5% degradation per year.
