DMEGC Solar claims its new solar panels weigh just 15.3kg and have a power output of up to 270W. The new products combine a double-glass design with TOPCon cell technology.
DMEGC, a Chinese industrial group that manufactures photovoltaic modules, has launched new lightweight TOPCon bifacial solar panels for residential rooftop PV projects.
“The DMxxxM10T-B32HBT dual-glazed module is a compact and easy-to-install design,” the manufacturer said in a statement. “Specifically designed for single-family homes and limited roof space, this module allows for optimal utilization of roof space using the latest module technologies.”
According to the company, the double-glass modules offer power ratings from 250W to 270W.
The new products measure 1,542 mm x 766 mm x 30 mm and weigh 15.3 kg. They feature 64 monocrystalline cells and have efficiencies between 21.6% and 22.9%.
The open circuit voltage varies between 23.26V for the 250W panel and 24.04V for the 270W version, depending on the manufacturer. The short circuit current ranges between 13.87A and 14.12A.
The ambient operating temperature ranges from -40°C to 85°C and the maximum system voltage is 1,500 V. The temperature coefficient is -0.29%/C. The panels have 2.0 mm double glazing and the junction boxes have an IP 68 protection rating.
DMEGC offers a 25-year product warranty and a 30-year power warranty. It claims that the output power can still reach 87.4% of its original performance after 30 years.
“The lighter and more compact design makes the daily work of installers easier, especially on existing roof slopes in single-family homes with difficult installation conditions,” says DMEGC. “The innovative design with optimised frame geometry ensures exceptional durability and gives the module great stability with load capacities of up to over 8100 Pa pressure load and -4000 Pa suction load.” |
