Description

  The present invention relates to a solar power generation device, and more particularly to a solar power generation device used in connection with cultivation of agricultural products.

  Conventionally, as a solar power generation apparatus related to cultivation of plants including agricultural products, for example, those disclosed in Utility Model Registration Document 1 and Patent Documents 2 and 3 are known. The solar power generation device disclosed therein includes a plurality of solar power generation panels and a support structure that is installed in a plant cultivation area to support these solar panels. However, it is not mentioned in the above-mentioned documents 1, 2 and 3 as to whether or not the cultivated land is a farmland referred to by the farmland law.

  In general, it is not permitted for the protection of farmland to install any structure on the farmland referred to by the Farmland Law. The so-called plastic house is a typical structure that is allowed to be installed on the farmland in accordance with the Agricultural Land Law, but there are various regulations for the installation to minimize damage to the farmland. . In short, a normal photovoltaic power generation apparatus has a support structure for fixing and holding a plurality of photovoltaic power generation panels, but such a support structure is allowed to be introduced into farmland referred to in the Agricultural Land Law. It is not.

On the other hand, one of the important environmental conditions for producing crops, especially vegetables, is the sunshine condition. Among the various vegetables, there are positive plants that prefer direct sunlight and do not grow in the shade, negative plants that prefer shade from the shade, and that tend to cause leaf burning when exposed to direct sunlight, and intermediate half-negative plants. is there.

  Representative examples of the positively cultivated plants include tomato, eggplant, bell pepper, potato, melon, pepper, cabbage, carrot, satsuma potato and onion. Such positive cultivated plants prefer to be in direct sunlight all day (approximately 6 hours or more) and do not grow in the shade.

  Typical examples of the half-negative cultivated plants include persimmon, spinach, komatsuna, persimmon, yam, lettuce, spring chrysanthemum, parsley, potato, taro, ginger, asparagus and the like. Such semi-negative cultivated plants prefer to be in direct sunlight for about half a day (approximately 3 to 4 hours) and can grow if there is sunlight through the sunbeams or lace curtains throughout the day.

  Typical examples of the negatively cultivated plants include trefoil, seri, watercress, shiso, kongo, rakkyo, cocoon and cocoon. Such negatively cultivated plants prefer shade from half-shade that is not exposed to direct sunlight, and can grow in 1 to 2 hours of sunshine per day. Mushrooms such as shiitake mushrooms grow in the shade.

  Therefore, the land suitable for the sunshine condition of each cultivated plant is selected as the cultivating place for the half-negative cultivated plant and the shade cultivated plant. Or the north side of the forest or forest will be chosen.

  When growing a half-negative cultivated plant or a shade cultivated plant in a vast field with good sunshine conditions, sunshade equipment is required according to the sunshine characteristics of the cultivated plant, and the equipment cost is relatively large Is a problem.

  Accordingly, the object of the present invention is a solar power generation apparatus that can be used not only for lawful farmland, but also as sunshade equipment for cultivation of half-negative and negative vegetables. It is to provide a solar power generation device that not only reduces the cost of the abatement equipment but also generates economic benefits in the future.

The photovoltaic power generation apparatus according to the present invention is installed on farmland referred to in the Agricultural Land Law, and has a rectangular bottom surface and is constructed on the farm ground, and on the top of the framework structure. And a plurality of photovoltaic panels provided. According to the present invention, in such a photovoltaic power generation apparatus, the framework structure is appropriately stretched between the support members and the support members arranged as appropriate along the sides of the rectangular bottom surface. It consists of reinforcing beam members, and the lower end of each column member is embedded in the farmland in the same manner as the column member embedding method when constructing a so-called greenhouse on the farmland, and the reinforcing beam member of the frame structure is It is used for detachably fixing the photovoltaic panel, and the photovoltaic panel is disposed on the top so as to cover at least 50% of the area of the sunlight transmitting region at the top of the framework structure.

In the solar power generation device according to the present invention, the solar power generation panel is preferably inclined so that it can receive sunlight efficiently.

Moreover, in the solar power generation device according to the present invention, the solar power generation panel is preferably arranged with regularity.

  Further, in the solar power generation device according to the present invention, a solar power generation panel may be spread over the entire solar light transmission region, and in this case, each solar power generation panel has an opening as a solar light transmission region. The ratio of the opening to the light receiving area of each photovoltaic power generation panel is 50% or less.

About the solar power generation device by this invention, since the frame structure is constructed | assembled using the technique of the conventional greenhouse, it can be installed legally on the farmland said by the farmland law. Further, in the photovoltaic power generation apparatus according to the present invention, the plurality of photovoltaic power generation panels are disposed on the top so as to cover at least 50% or more of the sunlight transmission region at the top of the frame structure. Since the amount of sunshine is reduced to 50% or less, the solar power generation device according to the present invention can be used not only as a sunshade facility for growing semi-negative crops on the farmland referred to by the Farmland Law, but also using the farmland. It is possible to perform solar power generation. Furthermore, although the initial investment cost of the photovoltaic power generation device itself according to the present invention is high, since the power generated by the photovoltaic power generation device can be used for living power and power sales, as a result, the photovoltaic power generation Not only will the equipment cost be reduced when the equipment is used as equipment, but it will also generate significant economic benefits in the future.
