Description

TECHNICAL FIELD [0001] The present invention relates to a solar power generator having a side reflector,

The present invention relates to a solar power generating apparatus having a side reflector, and more particularly, to a solar power generating apparatus capable of maintaining an internal vacuum state of a solar cell module during solar power generation using a solar cell module, reducing wind pressure resistance, And a side reflector which is detachable from the support of the solar module and is provided with a side reflector having a structure improved to improve the solar power generation efficiency by providing reflected light to the solar module side. To a photovoltaic device.

2. Description of the Related Art [0002] In general, photovoltaic energy has recently been introduced as a power generation device using solar energy because of its usefulness in that it is easy to use and can obtain a high efficiency and abundant energy compared with other energy sources.

A light collecting panel for collecting sunlight has a plate-like panel having a relatively large area for collecting a large amount of light energy from sunlight.

An example of an existing photovoltaic power generation device is a support frame in which a plurality of solar cell modules are mounted on an upper part thereof as disclosed in Korean Patent Registration No. 10-1371508 entitled " Photovoltaic Power Generation Device "(Registered Date: 2014.003.03). A first support unit for distributing and supporting the load of the support frame from below; A second support unit coupled to a lower side of the first support unit such that the first support unit can rotate in a vertical direction; And a cooling module provided below the support frame for cooling the back surface of the solar cell module, wherein the second support unit includes a drive motor for rotating the second support unit in a horizontal direction to transmit a rotational force to the second support unit, .

The above-described conventional technique has a disadvantage in that the solar light condensing efficiency is lowered because the solar light is applied to only one side surface or the other side surface.

In addition, the light collecting panel installed in the oblique oblique direction may be deformed or damaged by the wind pressure as the wind pressure is transmitted, and excessive heat may be transmitted to the condensing panel during the summer season, thereby deteriorating the parts.

Other prior art related to existing photovoltaic devices is disclosed in Korean Registered Utility Model No. 20-0461530 entitled " Reflective Focusing Photovoltaic Device "(Registered on July 12, 2012) 1. A solar cell comprising: a plurality of solar cells connected in series or in parallel; A support for slantingly supporting the solar panel with respect to the ground; At least one panel-side reflecting portion positioned on an edge side of the solar cell panel; And a spaced-apart reflecting portion provided at a position spaced apart from the panel-side reflecting portion to reflect the sunlight reflected by the panel-side reflecting portion back to the solar cell panel.

In this case, reflected light of the sunlight is transmitted to the solar cell module side by using the reflector, but the sunlight is concentrated. However, this is not applicable to the solar module, and the reflector is disposed at a fixed position There is a disadvantage that the reflection efficiency of sunlight moving along the locus is lowered.

In addition, since the existing reflection portion is provided outside, the reflection efficiency is lowered when foreign substances such as dust are adhered to each other. Therefore, it is troublesome for the operator to clean the surface of the reflection portion from time to time.
