Description

Stacked solar module system to increase power generation}

The present invention relates to a method of constructing a stacked solar module to increase power generation. More specifically, the present invention relates to a method of constructing a laminated solar module to increase power generation. More specifically, the present invention relates to a method of constructing a laminated solar module to increase power generation. More specifically, the present invention relates to a method of constructing a laminated solar module, which emits surface light through a wide range of light diffusion, scattering, and amplification by incident sunlight. By bonding and installing the module, power generation begins using the surface light emission of the light diffusion scattering plate. In addition, by bonding and installing an additional thin film mirror at the bottom of the light diffusion scattering plate, reflected light generated through the thin film mirror is also utilized. Therefore, it relates to a stacked solar module system for increasing power generation that has the advantage of generating power with high efficiency.

In addition, the present invention has the advantage of being able to configure stacked solar modules in various ways to suit needs and purposes, such as panel-type, square-column, or cylindrical shapes, and a method that enables higher-capacity power generation even with a smaller area compared to conventional solar modules. provides.

Photovoltaics (PV) is a power generation method that produces electricity by converting sunlight into direct current electricity. It usually uses solar modules with multiple solar cells attached.

Recently, as the demand for eco-friendly power generation using natural energy increases, the growth of related industries such as the production of solar power modules and the storage and use of power using solar power modules, as well as the production of various application products, are also showing a significant increase. there is.

However, the biggest disadvantage of solar power generation is low power generation efficiency. The generation efficiency of solar power generation is 8-15%, with an average of only around 12%. This is a very low figure compared to the power generation efficiency of 80-90% for hydroelectric power generation, 45-50% for thermal power generation, and 30-50% for nuclear power generation.

Additionally, a fairly large land area is required for high-power solar power generation.

For example, in solar power generation, a land area of 13.2 to 44 is required to build 1 power generation facility. In contrast, in nuclear power generation, a site area of 0.6 is required to build 1 power generation facility. In this way, it can be seen that solar power generation is very inefficient compared to nuclear power generation.

In addition, in Korea, mountainous areas are widely distributed in most areas except densely populated urban areas, so not only does it take a considerable amount of money and time to secure land for solar power generation, but it is also an obstacle to increasing the rate of solar power generation. It is becoming.

In addition, conventional solar modules use solar panels made by gathering several solar cells (solar cells) into a panel. The amount of power generation is determined by the area and quantity of the solar modules, except for double-sided solar modules. In most cases, solar modules are composed of single sections, so there are physical limitations to increasing power generation.

Therefore, a conventionally proposed technology to solve the above-mentioned problem is Republic of Korea Patent No. 10-1334092 (announced on November 28, 2013), which refers to a 'solar charging device with a rack-type structure'. ', a method of increasing power generation by using multiple solar modules for solar power generation in the stacking space of a rack with multiple stacking spaces, the shaded area of the solar modules composed of stacks is To solve this problem, a mirror having an angle adjustment part is installed and used around the rack.

In the conventional technology as described above, racks and mirrors must be constructed to install multiple solar modules, which increases manufacturing costs, and the entire solar power generation device, including the rack, is large in size and heavy, making it difficult to install. There is a problem that the installation cost for this also increases.

Therefore, with the development of new technology that can efficiently and easily integrate solar modules to minimize the installation area and at the same time increase the power generation amount by increasing the area of solar modules that can be generated, the disadvantages and problems of solar power generation described above are effectively addressed. We need a way to solve this problem efficiently.

And, the inclination angle of the inclined portion 70b is preferably set to an angle of 21 to 23 degrees. Here, the inclination angle of the inclined portion 70b refers to the angle between the horizontal plane and the inclined portion 70b.

When the inclination angle of the inclined portion 70b is 22°, sunlight incident in the direction opposite to gravity is transmitted to the light diffusion scattering plate 21 at an angle of 45° by the inclined portion 70b of the inclined prism bar 70a. It is reflected to the side of the side, surface solar module 15, and internal solar module 22, respectively.

In addition, the sunlight reflected on the side of the surface solar module 15 and the internal solar module 22 is generated by the first side power generation surface 15a and the fetal solar module 22 of the surface solar module 15a, respectively. By generating additional power through the second side power generation surface 22b, the amount of power generation can be further increased.

In addition, the sunlight reflected from the side of the light diffusion scattering plate 21 goes through diffusion, scattering, and amplification processes by the light diffusion scattering plate 21, and the first lower power generator formed on the bottom of the internal solar module 22 By generating power at the edge of the face 22a, the power generation amount of the internal solar module 22 can be further increased.

In addition, the mirror member 75 is provided at the lower part of the light diffusion scattering plate 21, and a curved portion 75a that is concavely curved downward is formed on the upper surface of the mirror member 75.

At this time, the curved portion 75a reflects sunlight that has undergone extensive diffusion, scattering, and amplification processes inside the light diffusion scattering plate 21 upward, thereby further increasing the power generation amount of the internal solar module 22. .

At this time, the depth of the bent portion 75a is preferably set to 0.25 times or less than the radius of the bent portion 75a. Here, the depth of the bent portion 75a refers to the distance from the upper surface of the mirror member 75a to the lowest end of the bent portion 75a.

The present invention using the above-described method and device can increase the area of solar modules that can generate power by stacking solar modules even in a narrow area compared to conventional solar modules with a single-sided power generation surface, resulting in high efficiency and high capacity. There is an advantage in that solar power generation is possible.

In addition, according to the present invention, not only can the required site be dramatically reduced compared to conventional solar power generation facilities that require a large site, but it is also possible to convert the low power generation efficiency, which is the biggest disadvantage of solar power generation, into high efficiency, and enable large-scale solar power generation. It can provide solar power generation technology with diverse and wide applicability, applicability, and usability, not only in photovoltaic power generation facilities but also in small-scale solar power generation fields.
