Trina Solar Ltd. has released the 60-cell PDG5, the first product in the company's new line of dual-rated frameless solar modules. According to Trina, the PDG5 is resistant to potential induced degradation and micro-cracking, and it does not require grounding.
By replacing the traditional backsheet materials of conventional solar modules with heat-strengthened glass, the PDG5 provides a heavy-duty solution for environments of high temperature and humidity, conditions that can accelerate performance degradation.
In addition, by reducing the module's glass thickness from the industry standard of 3.2 mm to 2.5 mm and applying an antireflective coating to the front glass, the company says it has enhanced transmission by an estimated 2.5%. MC4PLUS photovoltaic connectors increase system reliability.
Additionally, the modules are designed for 1,000 V IEC and 1,000 V UL applications. According to Trina, this setup enables longer installation runs to improve cabling, as well as lower hardware and labor installation costs.
PDG5 is being readied for worldwide shipments in the second half of the year.
