DMEGC, a Chinese industrial group that makes PV modules, has launched new lightweight bifacial TOPCon solar panels for residential rooftop PV projects.
“The DMxxxM10T-B32HBT double-glazed module in a compact and easy-to-install design,” the manufacturer said in a statement. “Specially designed for single-family homes and limited roof space, this module enables optimal use of roof space using the latest module technologies.”
The company said the double-glazed modules offer power from 250W to 270W.
The new products measure 1,542 mm x 766 mm x 30 mm and weigh 15.3 kg. They have 64 monocrystalline cells and have an efficiency between 21.6% and 22.9%.
The no-load voltage, according to the manufacturer, varies from 23.26 V for the 250 W panel to 24.04 V for the 270 W version. It said that the short circuit current ranges from 13.87 A to 14.12 A.
The operating ambient 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 are equipped with 2.0 mm double glazing and the connection boxes have an IP 68 rating.
DMEGC offers a 15-year product warranty and a 30-year performance warranty. It claims that the power can still reach 87.4% of its original performance after 30 years.
“The lighter and more compact design makes installers’ daily work easier, especially on existing roof slopes in single-family homes with challenging installation conditions,” DMEGC said. “The innovative design with optimized frame geometry ensures exceptional durability and gives the module high stability with load capacities of up to more than 8100 Pa pressure load and -4000 Pa suction load.”
