  • Patent number: 9419163
    Abstract: A solar panel capable of exhibiting excellent aesthetics and power generation efficiency, and capable of easily forming a protection plate in a manufacturing process is provided. The solar panel of the present invention comprises a protection plate 1 having translucency from a front surface 1a to a back surface, a solar battery cell, and an encapsulant that is integrally provided on the back surface, and fixes the solar battery cell to the back surface in sealed state. The protection plate is formed from a resin with polycarbonate as a main component by injection molding. The front surface serves as a design surface. A portion of the back surface that faces the solar battery cell serves as an offset surface that is offset with respect to the solar battery cell, and differs from the design surface in shape.

  • Patent number: 8827588
    Abstract: A fastening structure of a resin roof panel is disclosed for fastening a sunshade housing thereto. The sunshade housing includes an attaching portion. The roof panel includes coupling portions. The attaching portion and the coupling portions are fastened to each other by combined members. Each combined member is formed by combining a fastening bolt and a plate spring, and is inserted in an elongated hole. Each combined member permits the attaching portion and the associated coupling portion to be relatively displaced along the longitudinal direction of the elongated hole, and permits the attaching portion and the associated coupling portion to be relatively displaced along the axial direction of the fastening bolt through elastic deformation of the associated plate spring.
