The Chinese manufacturer has stated that its new Windproof Glass Sheet Module uses zinc-aluminum-magnesium surface alloy technology and a high-strength steel substrate. It offers a power conversion efficiency of up to 23.03%. Chinese PV module manufacturer Jolywood has announced a new TOPCon bifacial n-type glass sheet solar module for harsh climate conditions. The windproof module features a reinforced steel frame based on zinc-aluminum-magnesium surface alloy technology and a high-strength steel substrate, and reportedly offers “exceptional strength, corrosion resistance and resistance to extreme temperatures.” The frame is 50% stronger than traditional aluminum frames, providing superior resistance to wind and snow loads, the manufacturer said in a statement. The panel is available in five versions with power ratings from 570 W to 595 W and a power conversion efficiency between 22.07% and 23.03%. The open circuit voltage ranges from 51.17 V to 52.17 V and the short circuit current ranges from 13.76 A to 14.06 A. The module measures 2,278mm x 1,134mm x 29mm and weighs 28kg. It is made from 2.0-3.2mm tempered glass and an IP 68 rated junction box. The new product can operate at a system voltage of 1,500 V and temperatures between -40 ºC and 85 ºC. It has a temperature coefficient of -0.30% per degree Celsius. The manufacturer offers a 12-year product warranty and a 30-year power guarantee for 87.4% of the initial performance. “The module is explosion-proof, ensuring stable operation even in the most difficult environments,” he explains. “The result is 1.63% higher energy efficiency.” |
