Chinese solar module manufacturer Risen Energy has launched a new module for rooftop applications, based on 210mm cells. “It is a multi-bar solar module manufactured with non-destructive cutting technology, capable of operating at 21.7% efficiency, outperforming its peers by 0.4%, increasing solar ROI for users,” the manufacturer said in a statement.

Called RSM130-8-430-450M, the new 130-cell module is available in five versions with output power ranging from 430 W to 450 W and efficiencies ranging from 20.7% to 21.7%. The open circuit voltage is between 44.36 V and 45.33 V and the short circuit current is between 12.35 A and 12.65 A.

The panel measures 1894mm x 1096mm x 30mm and weighs 22.5kg. It is constructed with a white backsheet, low iron tempered anti-reflective glass and an anodized aluminum alloy frame. It also has an IP68 enclosure and the maximum system voltage is 1500V. The panel has a temperature coefficient of -0.34% per C and its operating temperature ranges from -40 C to 85 C.

The new product comes with a 25-year linear power warranty and a 12-year product warranty. The degradation in the first year is assumed to be 2% and the final output power over 25 years is guaranteed to be no less than 84.8% of rated output power.

“As an upgrade of Titan 40-cell high performance monocrystalline PERC solar modules, RSM130-8-430-450M has an output power range of 430Wp to 450Wp, which is 10-20Wp more than other consumer residential PV products on the market,” Risen said. “It’s compact and aesthetically pleasing, and comes with two color options – black and silver for its steel frame.”
