The Chinese manufacturer said its new rooftop solar panel offers 455–475 W power, 22.8–23.8% efficiency, 96-cell double-glazed design and IP68 protection.
Chinese solar energy manufacturer DMEGC has introduced a new addition to its roof portfolio with the G12RT-G48HBB, an all-black n-type monofacial module designed for residential and small commercial and industrial (C&I) applications.
The Infinity RT double glass module is available in five versions, with output power ranging from 455 W to 475 W and a conversion efficiency of 22.8% to 23.8%. The no-load voltage ranges from 36.18 V to 36.74 V, while the short-circuit current is between 15.78 A and 15.98 A.
The new product measures 1,762mm x 1,134mm x 30mm and weighs approximately 23kg. It is built on a 96-cell layout and features a 2mm + 2mm double-glazed structure. It also includes heat-strengthened glass with an anti-reflective coating on the front and a matching layer of glass on the back.
The IP68-rated module has a temperature coefficient of -0.29%/C and supports a maximum system voltage of 1,500 V, along with an overcurrent protection rating of 25 A.
From a reliability perspective, the module is covered by a 25-year product warranty and a 30-year linear performance warranty. The degradation profile includes a first year decline of no more than 1%, followed by an annual decline of up to 0.4%, resulting in approximately 87.4% of initial production after 30 years.
The product is certified to IEC 61215 and IEC 61730 standards and has passed additional tests for ammonia corrosion, salt spray, dust and sand, and light- and high-temperature-induced degradation, according to DMEGC. It is designed to operate within a temperature range of -40°C to 85°C and is said to withstand front loads of up to 5,400 Pa and rear loads of 2,400 Pa.
The company said the module is manufactured without PFAS materials and designed with a low carbon footprint. The production facilities have achieved SSI ESG Silver certification, aligning the product with growing European environmental requirements.
Another key feature of the module is its encapsulation, which uses a black ethylene-vinyl acetate (EVA) layer on the back to improve internal light reflection in the cell structure. According to the manufacturer, this design can increase energy yield by approximately 1% compared to conventional configurations.
