With the development of distributed market and BIPV project, lightweight modules have become increasingly popular. For lightweight modules, many customers concern about their anti-load capacity, adhesive strength and reliability. In fact, with shingled cells this module can prevent from hidden cracks even under heavy loads. The highly reliable acrylic acid double-sided tape used to fix the bonded module can retain high adhesive strength after prolonged outdoor use. The stable, highly reliable substrate made of fluorine composite materials are characterized by properties that resist ultraviolet light and aging.
