Energy Products, Projects and Devices Design Longi Hi Mo X6 Artist Solar Pv by Longi Green Energy Technology Co.,Ltd. Longi Hi Mo X6 Artist is a photovoltaic module designed for home solar power systems. The module uses HPBC black cell technology, which creates a pure black appearance. The front surface has no solder strips or grid lines, so light is received from many angles. A low reflective texture and an antireflective film keep the colour uniform when the module is viewed from different directions. The structural glass carries a micro carved texture that spreads light evenly and reduces glare. Bifacial glass and a double POE structure support stable and reliable power output.
