Sunman unveils 520 W glass-free solar panel with 19.3% efficiency

The new panel has a white backsheet and a temperature coefficient of -0.34/C. It weighs 4.1 kg per m2 and, according to the manufacturer, supports all types of installation methods, including roof adhesive and removal mechanical mounting.

Chinese solar module manufacturer Sunman has launched new monocrystalline panels with a power output of up to 520 W.

“Our new product supports all types of installation methods including quick-bonding and removable mechanical mounting,” a spokesperson from the company told pv magazine. “The module comes pre-integrated with mounting hardware and bracket, which saves 40% of installation time.”

The SMH520J-12X12UW module features a power conversion efficiency of 19.3%. Its open circuit voltage is 49.5 V and the short-circuit current is 13.56A.

The new product has a size of 2,246 mm × 1,197 x 2 mm and weighs in at 11.1 kg or 4.1 kg/m2. It relies on 144 half-cut monocrystalline cells, a white backsheet, a frame made of anodized aluminum alloy, and a junction box with an IP 68 rating.

The glass-free panel can be used in PV systems with a maximum voltage of 1,500 V and an operating temperature between -40 C and 85 C. The power temperature coefficient is -0.34% per degree Celsius.

The new module, which comes with a 25-year linear power output warranty and a 12-year product guarantee, is manufactured through a process based on the use of glass fiber reinforced plastic (GRP), which the manufacturer says reduces light reflection and opens up new assembly options.

The 25-year end power output is guaranteed to be no less than 84.8% of the nominal output power.
