Description

Photovoltaic power plant with reflective mats for light collection}

The present invention relates to a photovoltaic power generation facility that generates electric energy by using sunlight, and in more detail, a solar module is installed in both upper and lower sides, and is located at the lower part of the photovoltaic module. By installing the reflective mat so that the reflective mat reflects sunlight on the lower part of the photovoltaic module to increase the light collection efficiency, the power generation of electrical energy is further improved, and the installation area is not increased and the reflective mat is installed at a low cost as well as It is a technology related to a photovoltaic power generation facility equipped with a reflective mat for light collection that prevents deformation and damage of the reflective mat.

In general, as the depletion of fossil fuels and environmental pollution have reached a very serious level, recently, policies to expand new and renewable energy and investment in facilities are being actively carried out. Among them, solar energy is easier to use compared to other energy sources, Because of their high efficiency, interest in solar power generation facilities is increasing.

Most of the recent solar power generation facilities are divided into fixed type and location tracking type. Here, the fixed type is a method of installing the power generation facility at the most appropriate angle and orientation by comprehensively analyzing the altitude and sunlight of the sun, and the location tracking type is This is a method in which the position of the solar module varies according to the altitude and orientation of the sun.

In areas where there is little sunlight due to frequent rainfall, such as our country, power consumption according to the tracking of the sun is relatively large, which is a factor that lowers power generation efficiency.

Recently, in order to increase the power generation efficiency of solar power, technologies for installing solar modules on both upper and lower sides and concentrating sunlight from the upper and lower solar modules to generate power have been proposed, but these technologies are relatively inexpensive compared to the installation cost. The power generation efficiency is insufficient.

Therefore, as a prior art for improving the power generation efficiency of sunlight by installing a reflector on one side of the photovoltaic module, Korean Patent Registration No. 10-1854450 (photovoltaic power generation device equipped with a side reflector) has been proposed.

In this prior art, as the side reflector is detachably coupled to the bottom plate of the support base of the photovoltaic module, the side reflector can be installed or omitted depending on the place or environment in which the photovoltaic module is installed, so the user's convenience can be increased. In addition, the side reflector reflects the sunlight and transmits the reflected light to the solar module, thereby providing the effect of improving the solar power generation efficiency.

In addition, as a prior art for increasing the amount of solar power generation by using a reflective film made of a conventional flexible material, Korean Patent Registration No. 10-1954390 (solar light reflection and condensing system of a solar panel) has been proposed.

In this prior art, the sunlight reflected through the light reflection unit is reflected and condensed to the panel to increase the amount of power generation to an appropriate level, and it prevents deformation and damage by accommodating a flexible reflective film in unnecessary situations such as bad weather or night time. , provides the effect of lightening the frame for supporting the photovoltaic panel and the light reflection unit and simplifying the structure.

However, the "photovoltaic power generation device with side reflector" presented in the prior art has improved solar power generation efficiency, but as a separate reflector is installed on the outside of the photovoltaic module, the installation area is relatively wide, and the construction cost is There is a problem with excessive consumption.

In addition, the "solar reflection and condensing system of the solar panel" presented in the prior art has the advantage of more improved power generation efficiency and folding and accommodating the reflective film in bad weather or at night, but there is no space to install the reflective film on the outside of the solar panel Therefore, there is a problem in that the installation area is widened.
