Solarwatt unveils two bifacial glass-glass panels with half-cell design

Germany-based PV module manufacturer Solarwatt has launched two bifacial glass-glass panels with half-cell architecture and an M6 format: The Solarwatt Vision Pure panel, with aluminum frame; and the black-framed Solarwatt Vision Style panel, with a transparent backsheet.

The Vision Style product is available in three versions with power output ranging from 370 W to 380 W and a power conversion efficiency of between 19.9% and 20.4%. It measures 1,780х1,052х40mm, weighs 25 kg and is built with 120 monocrystalline PERC cells with a size of 166x83mm.

The panel features an open-circuit voltage ranging from 33.9 V to 34.5 V and a short-circuit current of 10.99 A to 11.15 А. The maximum system voltage is 1,000 V.

The Vision Pure module is available with three different wattages spanning from 365 W to 375 W and efficiency ranging from 19.6% to 20.2%. It has the same size, weight, and number of cells as the Vision Style panel and also the same system voltage. Its open-circuit voltage ranges from 33.6 V to 34.2 V and the short-circuit current is between 11.45 A and 11.65 А.

The temperature coefficient for both panels is -0.37% and the manufacturer offers a 30-year product guarantee and a 30-year power output guarantee. The panels are said to be able to operate at 87% of their original performance at the end of the guarantee period.

The company said the new modules are being produced at its manufacturing facility in Dresden, eastern Germany, where it recently invested €15 million in the deployment of its new F8 production line. Another pilot line is expected to be installed at the factory next year, the manufacturer added, without providing more details.
