PURPOSE:To enable directivity of an incidence efficiency to be generated and eliminate a need for an additional mechanism for adjusting an installation angle between an installation-type solar battery and a foundation by forming an inclination surface which is asymmetrical left and right or front and back at a proper spacing on the surface of a translucent plate-like or film-like covering material for covering the surface of the solar battery. CONSTITUTION:A covering material 10 for a solar battery 20 consists of a colorless and transparent glass or a translucent substance such as acryl resin, and the surface side has a wave shape and at the same time the rear side has a flat face. In the surface of the wave shape, a vertical surface 11 which is extended in the normal direction which is erected on the surface of the solar battery 20 and an inclination surface 12 which is extended in a direction which is at an angle of theta for the surface of the solar battery are repeated at a specified pitch. The pitch of the vertical surface 11 is set to a value which is two times larger than that of the surface electrode layer of the solar battery and at the same time each vertical surface is laid out directly above the surface electrode layer. Also, a flat rear surface of the film body 10 is joined to the surface of the solar battery 20 by an adhesive layer 30. |
