Description

  The present invention relates to an agricultural greenhouse provided with a solar panel for photovoltaic power generation.

  In May 2010, the House of Environment Committee passed the Global Warming Countermeasures Law, which clearly stated the goal of reducing greenhouse gas emissions by 25% by 2020 compared to 1990 levels. Furthermore, according to this law, the supply amount of renewable energy such as solar power generation will be raised to 10% of the total supply amount. And as one of the basic measures for that purpose, the creation of a fixed-price purchase system for electric power companies to purchase renewable energy at a fixed price is stated. Therefore, the expansion of photovoltaic power generation with the lowest CO2 emission among renewable energies is an urgent policy.

  On the other hand, in general, an agricultural greenhouse has a relatively large installation area and is installed in a place with good sunshine conditions. Considering this point, it is suitable as a place where a solar panel is installed. As an agricultural greenhouse provided with such a solar panel, for example, an agricultural greenhouse described in Utility Model Registration No. 3152366 (Patent Document 1) has been proposed.

  The agricultural greenhouse has a side wall and a single-flow gradient roof provided on the upper side of the side wall, and a framework (for example, a column) and a panel constituting the side wall and the gradient roof are made of fiber reinforced plastic (FRP). A solar panel is laid on the sloped roof, and the generated electricity is exclusively used for self-use.
