<p>PROBLEM TO BE SOLVED: To prevent damage to a power-generating element due to the tensile of a coating film for a plastic house so that a cost for periodic replacement is suppressed while attaching is easier, related to a photovoltaic generator which is attached to a plastic house and the like for agricultural application as an independent power supply source. SOLUTION: On a solar cell module 7 where an amorphous silicon power- generating element 8 is sealed with a translucent sheet 9, a transparent jacket film 12 is attached so as to be a fitting margin 12a is formed at both ends, constituting a photovoltaic generator 6. The solar cell module 7 is so held as to freely move relative to the jacket film 12. When the photovoltaic generator 6 is attached to a pillar, each fitting margin 12a is tightly fitted with a fixing bracket of U-shape in cross section. Thus, the solar cell module 7 is not restrained by the jacket film 12, and the tensile acting on the jacket film 12 does not act on the solar cell module 7. Replacing only of the jacket film 12 completes replacement operation of the photovoltaic generator 6.</p> |
