Description

Environmental friendly lens for improving solar efficiency {Environmental friendly lens for solar heating}

The present invention relates to a condensing lens for photovoltaic power generation, and more particularly to an environmentally friendly condensing lens having a structure that can use sunlight incident from all angles and directions, and can increase the generation efficiency of solar light.

In the photovoltaic device, a light collecting means such as a light collecting lens or a light reflecting mirror, which collects sunlight and irradiates a light collecting surface of the solar cell, is used. The light intensity and illuminance uniformity of the light collecting means are directly related to the energy efficiency of the power generation equipment. . However, the conventional light collecting means has a problem that it is very difficult to maintain uniformity of illuminance on the light collecting surface of the solar cell because it uses a continuous change of the optical surface.

In addition, the size of the condenser lens is increased in size according to the power generation capacity, the conventional condenser lens has a problem that is very difficult to manufacture because the optical surface is formed continuously. On the other hand, a solar cell used for photovoltaic power generation is configured by connecting a plurality of unit cells in series or in parallel in order to generate a high voltage, the performance of which is determined by a unit cell having a small light irradiation amount of the unit cells. Therefore, when a conventional condenser lens having uneven illuminance on the condensing surface is used, a problem occurs in that the performance of the entire solar cell is deteriorated by a unit cell disposed at a relatively low illuminance.

The technical problem to be achieved by the present invention is to provide an environment-friendly condensing lens that can use the sunlight in all directions, evenly distributed sunlight.

Condensing lens according to an embodiment of the present invention for achieving the above technical problem is configured by connecting a pentagonal or hexagonal Fresnel lens, surrounds the solar cell plate at the bottom, can receive sunlight incident from all angles It is an environmentally friendly condenser lens for improving the solar efficiency with a structure.

The condensing lens of the present invention has an advantage of being covered with a solar cell plate generated by solar light, so that solar light is spread evenly on the solar cell at all angles, thereby increasing power generation efficiency. In addition, the condensing lens of the present invention is a transparent lens is attached in the form of a pentagon and hexagon, the lower portion is formed with a discharge hole for dissipating the heat inside to the outside, the size can be adjusted according to the size of the solar panel There is this. In addition, circular valleys and mountains are formed in each transparent lens, and the direction of sunlight can be adjusted by adjusting the angle of the mountains.
