<P>PROBLEM TO BE SOLVED: To provide a solar battery panel which, unlike a conventional solar battery panel structure, is lightweight and producible at low cost, and, in addition, has high freedom of design against the size of a solar battery panel and excels in wind pressure resistance. <P>SOLUTION: The solar battery panel includes a single or plural sheets of solar battery element which are encapsulated with urethane resin on a transparent resin substrate, where the transparent resin substrate side is made a light receiving surface. The above being its basic construction, the solar battery panel further is composed in such a way that castor oil based polyol is contained as the urethane resin, that hexamethylene diisocyanate is contained as the urethane resin, that castor oil based polyol made to be free of double bonds by hydrogenation is contained as the urethane resin, the above compounds being used in combination, and that plural air vents penetrating from the transparent resin substrate to the urethane resin are provided within at least an array range of the solar battery elements. <P>COPYRIGHT: (C)2013,JPO&INPIT |
