Semi Flexible ETFE series photovoltaic module is an innovative glass-free solar module. It adopts proven crystalline silicon solar cell technology and polymer composite material to achieve a new type of pv module that is glass-free, lightweight and thin sheet.  TF series is as light as 3.5 kg/m2, which is only 30% of glass module and 55% of PA028 lightweight module. The thickness can be reduced to 2mm. We customize the shape and size and achieve custom design and productio
