At the EnerGaïa trade show in France, Chinese manufacturer DMEGC unveiled the DMxxxM10RT-54HBW-LV lightweight rooftop solar module designed for roofs with low load-bearing capacity, weighing less than 7.5 kg/m2. With a power output of 460 W, the module meets the requirements of fragile roof structures and is certified to IEC standards. By utilizing thinner glass, the module aims to make thousands of square meters of rooftops usable for solar energy, offering a promising solution for expanding solar energy capacity in areas with limited roof strength.
