China’s Eging has announced a new series of bifacial TOPCon solar panels based on n-type wafers and 182 mm cells. The temperature coefficient of the modules is -0.30% and the efficiencies are 21.67% – 22.45%.
The Chinese module maker said the Star Pro series is available in five different versions, with powers ranging from 560W to 580W and a power conversion efficiency of 21.67% to 22.45%. The breakdown voltage is between 50.70 V and 51.42 V and the short-circuit current is 14.12 A and 14.37 A. The panel can operate at a maximum system voltage of 1500 V and at operating temperatures of -40 C and 85 C.
The modules measure 2278 mm x 1134 mm x 30 mm and weigh 31.7 kg. They also feature an IP68 rated junction box, 2mm tempered glass, anodized aluminum alloy frame and multi-rail technology (MBB). Their temperature coefficient is -0.30% per degree Celsius.
“Compared to the same version of P-type products, the power of Eging PV Star-Pro products increased by 10 W to 15 W, with lower linear power degradation, better temperature coefficient and low radiation power,” a company spokesperson said. pv magazine. “This can increase power generation by 3%, reduce balance of system costs by 2.5% and reduce LCOE by 6%.”
New products have a 12-year product warranty and a 30-year performance warranty. The first year degradation is claimed to be 1%, and at the end of 30 years the power is guaranteed to be at least 87.4% of the rated output power.
The solar panels are based on n-type wafers and 182 mm cells. They are suitable for utility projects as well as industrial and commercial roofing projects.
Eging said it plans to deploy 5 GW of n-type TOPCon modules and 10 GW of cell production capacity by the end of this year.
