GxB Series


A POWERFUL PRODUCT PORTFOLIO


Sunpreme has a powerful product line consisting of Bifacial HCT panels with STC power ratings of 330W, 390W and 520W. Both 330W and 390W panels come with an integrated optimizer option to ensure the benefits of ~15% bifacial boost, enable remote monitoring and shut-off. With the recommended 15º tilt, these frameless modules require little or no cleaning against dust. For distributed power generation from commercial and residential roof tops, these panels provide undisputable competitive benefits. For ground mounted applications, configuring South facing panels at 25-30º tilt with vertically mounted E-W panels, we can generate a 3-peak power profile over a single day – thereby dramatically increasing the energy production without wasteful power clipping.
