Description

Solar power generation device {PHOTOVOLTAIC APPARATUS}

The present invention relates to a photovoltaic device, and more particularly, to a photovoltaic device used to perform photovoltaic power generation by installing or constructing a photovoltaic power generation facility at a place.

Alternative energies such as solar power generation, wind power generation, fuel cell power generation, solar thermal power generation, and small cogeneration are in the spotlight as an alternative to fossil fuel power generation in response to an increase in power consumption due to industrial power generation and improvement of living standards.

Among these alternative energies, solar power generation using solar light as an energy source is being developed to improve efficiency, or some are already being put to practical use.

And, a representative example of the photovoltaic power generation is to use a solar cell.

A solar cell is an energy conversion device that converts solar light energy into electrical energy by applying a photovoltaic effect.

In a solar cell, when light is incident on the substrate surface, electrons and holes are generated inside, and the generated charges move to the 'P' pole and the 'N' pole, thereby generating a potential difference, that is, photovoltaic power.

And, the efficiency of such a solar cell is determined according to how efficiently it can absorb light incident on the substrate surface.

Therefore, various technologies for improving the light collecting efficiency of solar cells are being developed.

At this time, since the orbit of the sun continuously changes from sunrise to sunset, the inclination angle of the light collecting device for collecting sunlight also needs to be adjusted according to the incident angle of sunlight.

And, various techniques for this are disclosed in Patent Registration No. 10-1090537 and the like.

However, the prior art is structurally very complex, and since the solar cell panel is tilted on the module frame perpendicular to the installation target surface, there is a limit in that the light collecting efficiency is inevitably reduced.

In particular, the prior art is to be installed on the wall of a public facility or building, such as a bus stop or a taxi stand, there is a difficult problem in the production of large-capacity power with such an installation structure.

Therefore, it is urgent to develop a device capable of generating large-capacity power generation while minimizing exposure or exposure time to external pollutants, thereby preventing the occurrence of a problem of lowering power generation efficiency and improving space utilization.
