China’s Eging has unveiled a brand new line of bifacial TOPCon photo voltaic panels primarily based on n-type wafers and 182 mm cells. The modules have a temperature coefficient of -0.30% and efficiencies starting from 21.67% to 22.45%.
Eging launched a brand new line of bifacial n-type TOPCon photo voltaic panels on the SNEC commerce present this week in Shanghai, China.
The Chinese language module producer mentioned the Star Professional sequence is offered in 5 totally different variations, with energy outputs starting from 560 W to 580 W, and energy conversion efficiencies from 21.67% to 22.45%. The open-circuit voltage is between 50.70 V and 51.42 V and the short-circuit present is between 14.12 A and 14.37 A. The panel can function with a most system voltage of 1,500 V and working temperatures of -40 C and 85 C.
The modules measure 2,278 mm x 1,134 mm x 30 mm and weigh 31.7 kg. In addition they characteristic an IP68-rated junction field, 2 mm tempered glass, an anodized aluminum alloy body, and multi-busbar (MBB) know-how. They’ve a temperature coefficient of -0.30% per diploma Celsius.
“In contrast with the identical model of P-type merchandise, Eging PV Star-Professional merchandise energy elevated by 10 W to 15W, with decrease linear energy degradation, higher temperature coefficient, and low irradiance energy era efficiency,” an organization spokesperson instructed pv journal. “This could improve energy era by 3%, cut back stability of system prices by 2.5%, and cut back LCOE by 6%.”
The brand new merchandise include a 12-year product guarantee and a 30-year efficiency guarantee. The degradation within the first yr is purportedly 1% and 30-year finish energy output is assured to be a minimum of 87.4% of the nominal output energy.
The photo voltaic panels are primarily based on n-type wafers and 182 mm cells. They’re appropriate for utility-scale tasks, in addition to industrial and industrial rooftop tasks.
Eging mentioned it plans to function 5 GW of n-type TOPCon module and 10 GW of cell manufacturing capability by the top of this yr.
