Bauer Solar unveils 420-430W bifacial glass-glass module for rooftop applications


From pv magazine Germany

Bauer Solar has expanded its product portfolio to include a bifacial glass-glass module series with outputs of 420 W, 425 W, and 430 W. Called “Premium Protect,” the module series was developed specifically for use in residential and commercial rooftops. It will be available from the beginning of 2023.

Each modules measures 1,722 mm x 1,134 mm x 30 mm and weighs 24.7 kg. Bauer grants a 30-year product and performance guarantee, with the most powerful module consisting of 108 monocrystalline n-type half-cells. According to Bauer, the average efficiencies are 21.51% for the 420 W module, 21.76% for the 425 W, and 22.02% for the 430 W. The series replaces the previous model with 385 W and 400 W.
