Leapton says its new panels have a temperature coefficient of -0.30% per C and an efficiency of up to 23.14%. They come with a 30-year performance guarantee for 87.4% of the initial yield.
Japan-based Leapton Energy Co., Ltd. has released a new double-glazed solar panel based on n-type tunnel oxide passivated contact (TOPcon) technology and rectangular wafers.
The LP182*210M66NB modules feature 182mm x 210mm n-type TOPCon cells and an aluminum alloy frame.
“The modules are based on 210R cells, which offer the advantage of low open-circuit voltage, resulting in higher string power,” a company spokesperson said. pv magazine. “In a typical 1500 V ground station system design, each string can connect two additional modules, increasing string power by 13%.”
Leapton offers six versions of the panels, with power ratings ranging from 600 W to 625 W. Efficiency values range from 22.21% to 23.14%. The no-load voltage is between 44.54 V and 49.75 and the short-circuit current is between 15.78 A and 16.00 A. The maximum system voltage is 1,500 V.
The panels measure 2,382 mm x 1,134 mm x 30 mm and weigh 33.5 kg. They also feature an IP68 housing, 2.0mm anti-reflective glass on the front and 2.0mm heat-resistant glass on the back. They have a temperature coefficient of -0.30% per degree Celsius and an operating temperature ranging from -40 C to 85 C.
The new products come with a 30-year linear performance warranty and a 25-year product warranty. The first year degradation is reported to be 1.0%. The final power over 30 years is guaranteed to be no less than 87.4% of the nominal output power.
“Using our 210R-66 mid-size modules reduces the number of strings, total length and number of tracking brackets by 13%, and reduces the number of modules, DC cables and MC4 connectors by 5%-8%.” the spokesperson added.
Leapton Energy had a production capacity of 3.5 GW in China at the end of 2023.
