On the one hand, the lightweight module of DAS Solar is designed with narrow shingled cells that have little deformation under the same bending conditions. On the other hand, it uses conductive resin instead of traditional solder strip to connect cells. The elastic conductive resin can reduce the stress on the cells themselves when the module deforms. In this case, the internal cells will not have serious hidden cracks when the lightweight module deforms. Moreover, hidden cracks have little influence on the shingled module because the shingling technology makes the entire cell surface conductive as compared to the ordinary module where the solder strip conducts electricity.
