Description

Solar photovoltaic generator having reflective part {solar photovoltaic generator having reflective part}

The present invention relates to a photovoltaic device, and more particularly, to a photovoltaic device including a reflector capable of maximizing photovoltaic power generation efficiency.

In recent years, solar power generation is rapidly decreasing the power generation cost per unit power generation capacity along with the improvement of the productivity of the solar module, which is a major material, and the market is also rapidly expanding.

In order to maximize the efficiency of solar modules for photovoltaic power generation, it is most advantageous to install the photovoltaic module vertically with the photovoltaic power, and accordingly, the power generation efficiency due to the shade and the south-central altitude of the sun for each season according to the installation area can be reduced. The installation angle is determined in consideration. In domestic solar power facilities, solar modules are mainly installed with an inclination of around 20 degrees.

The supporting structure of the solar module is installed for the purpose of maintaining such an installation angle, maintaining the solar module, preventing damage, etc. At this time, a metal material such as steel or aluminum is mainly used.

In the supporting structure of the existing solar module, the frame, which serves as a pillar of the structure, is erected vertically on the ground, and a girder is fastened to the upper part of the frame to secure a space to install the solar module. After fastening the girder, a plurality of perlins are installed on the upper part of the girder in a direction orthogonal to the girder, and a photovoltaic module is installed on the upper part of the perlin, so that the load of the solar module is transmitted to the frame through the perlin and the girder.

As for the frame, various types of foundations are applied, such as a method of installing the frame directly in the ground, such as a rotary penetration type foundation and a direct penetration type foundation, and a method of placing a separate foundation on-site (Reinforced Concrete) or pre-cast concrete (Pre-cast concrete). I can.

However, unlike general structures, the supporting structure of the photovoltaic module does not have a large required load, so a rotational or direct penetration type foundation is mainly used for cost reduction.

When the frame is constructed using the above-described rotary penetration type or direct penetration type foundation, construction errors such as an irregular height of each frame may occur during the process of installing and embedding the frame on the ground. In addition, as the construction error of the support structure is corrected, the construction period may be delayed, and the support performance of the support structure may be deteriorated.

In order to solve this problem, as shown in Fig. 1, a structure including a plurality of frames installed perpendicular to the ground and arranged in parallel at the front and rear, a girder supporting a solar module, and a bridge connecting adjacent frames The supporting structure of the solar module of was developed.

However, in the prior art shown in FIG. 1, the support structure of the solar module merely serves to support the solar module, and has a problem in that the power generation efficiency of the solar module cannot be improved.

Therefore, there is a need for a technology capable of solving the problems according to the prior art mentioned above.
