The Singapore-based manufacturer said its new panel can be self-cleaning through rainwater thanks to its frameless design. The new product has an operating temperature coefficient of -0.30% per C and an efficiency ranging from 21.51% to 22.53%.
Singapore-based solar manufacturer Gstar has unveiled a frameless TOPCon solar module for residential applications.
“The Cleanedge seriess has successfully obtained patent certification from the United States Patent and Trademark Office (USPTO) due to its innovative design,” a company spokesperson said. pv magazine. “The most striking feature is the frameless design on the front, which eliminates the protrusion of traditional module frames, not only making the module look full-screen, but also significantly preventing the accumulation of water and dust in practical applications.”
The manufacturer claims that the module can be self-cleaning using rainwater and enables 6-15% higher power generation over the entire life cycle compared to conventional modules.
The series is available in five versions, with powers ranging from 420 W to 440 W, and efficiencies from 21.51% to 22.53%. They are made with 108 TOPCon, half-cut monocrystalline solar cells and have a maximum system voltage of 1,500 V.
The solar panels have no-load voltages ranging between 38.11 V and 38.87 V, along with short-circuit currents ranging from 14.07 A to 14.39 A. All versions of the solar panels have dimensions of 1,722 mm x 1,134 mm x 32 mm and a weight of 22 kg.
These panels can operate within a temperature range of -40 C to 85 C and exhibit an operating temperature coefficient of -0.30% per C. They feature 3.2mm solar glass with anti-reflective treatment, an IP68 rated junction box and a black back plate.
The company offers a 30-year linear performance warranty and a 25-year product warranty. The final power over 25 years is guaranteed to be no less than 87.4% of the nominal output power.
Gstar currently operates a 2 GW solar module factory in Laos and in late August signed a Memorandum of Understanding (MoU) for a 2 GW solar module manufacturing project in the UAE, focusing on high-efficiency N-type technology.
Earlier this year, Gstar also announced that it had completed construction of a 3 GW wafer factory in Indonesia, with production expected to start by the end of the year.
