Description

Farming type double sided collective photovoltaic module system}

The present invention relates to a farming-type double-sided solar module system, and more specifically, it is installed on farmland where crops are cultivated to produce sunlight as electricity, but condenses sunlight from the top and bottom surfaces to increase the efficiency of electricity production. , It relates to a farming type double-sided solar module system with improved stability by further provided with a vibration-proof module that prevents the structure from shaking even by a disaster such as vibration or earthquake generated by various agricultural machinery used in farmland.

Agricultural cultivated land for agriculture (hereinafter, abbreviated as'farmland') is mainly formed in a plain area with high sunlight and no objects generating shadows around it, and is cultivated in alpine areas according to temperature variations among the growing conditions of crops. There are also.

Among the crops cultivated in such farmland,'rice' is mainly cultivated in the plains where there are no large mountains or structures around the crops, where sunlight must be high and water at a certain level must be always filled.

Meanwhile, solar light is easier to use than other energy sources and can obtain high-efficiency and abundant energy, and devices for generating electricity by condensing sunlight have been proposed.

Such a photovoltaic device includes a configuration that measures the altitude or azimuth of the sun or tracks sunlight according to a pre-programmed method according to time, and then condenses sunlight through a condensing panel and converts it into electricity. .

Here, the condensing panel is for condensing heat energy from sunlight, and a flat plate-shaped panel is used to condense a large amount of thermal energy, and is arranged to have a predetermined inclination angle toward the direction in which the sun is illuminated.

Since conventional light-converging panels are arranged in the direction in which the sun shines, that is, facing the sky, there is a problem in that the efficiency of electricity production varies depending on the position of the sun that changes over time, making it difficult to produce stable electricity. .

In addition, as the usage time elapses, yellow sand, snow, dust, and foreign substances are adsorbed on the surface of the light-converging panel, so that the efficiency of electricity production could be maintained only by periodically cleaning the surface.

In addition, since the conventional light-converging panel condenses sunlight only on the top surface facing the sun, that is, facing the sky, there is a problem that the amount of electricity that can be produced is not large compared to the installation area, and a number of light-converging panels are installed to solve this problem. In this case, there is a problem that the amount of sunlight that must be irradiated with the crop decreases as the light collecting panel covers the crop.

In addition, in order to irradiate the crop with appropriate sunlight, it is installed at a height of 5M or more from the ground, and thus, it is difficult to clean the surface of the light-collecting panel, and thus, there is a problem in that the light collecting efficiency decreases as the use time increases.

On the other hand, when installed in farmland, the structure is shaken by vibrations transmitted from various agricultural machinery used to grow crops in the farmland, and vibrations transmitted when an earthquake occurs, and when such vibrations are transmitted to the joint part of the light collecting panel and the structure, this part is There is a problem of being damaged, and when the joint portion is damaged, the light collecting panel falls, and there is a problem that crops being cultivated in the farmland are damaged by the fallen light collecting panel.

1 is a schematic diagram showing a farming type double-sided solar module system 1 according to the present invention,

A structure 10 including a post 11 installed on the ground;

A plurality of solar modules 20 disposed on the structure 10;

And a coupling module 30 formed on the body part 21 and coupled to the structure 10.

The structure 10 includes a plurality of posts 11 arranged at mutually spaced intervals, and a reinforcing rod arranged in a transverse direction with respect to the post or in a form in which a plurality of intersects each other in order to increase the supporting force of the post 11 May be further provided.

The post 11 is in the form of a rod extending in the longitudinal direction, and may be formed in various shapes such as circular, square, and polygonal, and the lower end is fixed to the ground.

Here, a vibration isolating module 40, which will be described later, is disposed at the lower end of the post 11, and the vibration isolating module 40 is coupled to the lower end of the post 11 to be fixed to the ground.

In addition, the post 11 is preferably made of a material that is resistant to corrosion, has strong durability, and does not generate static electricity even though it is a lightweight material. For example, stainless steel or stainless alloy may be used as a material.

The solar module 20 is detachably coupled to the structure 10 and condenses sunlight,

A body part 21 made of a flat plate and including a glass material through which sunlight passes, and

Including a solar light collecting cell 22 disposed on the body portion 21,

The upper surface 221 collects sunlight directly from the sun,

The lower surface 222 condenses sunlight reflected from the ground or water after passing through the body portion 21, or sunlight reflected from the ground or water after being irradiated from the outside of the body portion 21.

The body part 21,

An upper POE 211 stacked on the upper surface of the solar condensing cell 22,

An upper tempered glass 212 laminated on the upper POE 211,

And a lower transparent back sheet 214 stacked on the lower POE 213.

The upper POE 211 and the lower POE 213 are made of the same material, and are made of POE (Polyolefin Elastomer) having high elasticity, low heat sealing temperature, impact reinforcement and moisture-proof effect.

Here, the POE is a'polyolefin elastomer', which is a material mainly used for shoe soles, films, wires, and communication cables. It has a very high flash point of 340°C and has a low risk of fire, has no odor, and has no pH. And as a material having stable chemical properties at normal pressure, especially when it is moisture-proof, it is very high, and serves to protect the solar light collecting cell 22 from external moisture in a solar module mainly installed outside.

The reason for using the POE in the present invention is that the farmland where crops are grown is always filled with agricultural water for crops, or because water is supplied to the crops, the humidity is relatively high compared to other terrains, and this humidity increases due to external temperature. It gets higher as the water increases in the summer.

In the conventional photovoltaic module, a sheet formed mainly of EVA was arranged. However, since EVA has relatively weak moisture resistance compared to POE, it cannot be blocked when the humidity is high, which damages the photovoltaic cell, resulting in the reduction of electricity production efficiency. Problems such as deterioration occurred.

Therefore, by disposing POE having high moisture resistance, it is possible to prevent damage to the solar condensing cell and decrease in production efficiency due to humidity.

The upper tempered glass 212 is laminated on the upper POE 211, and in the present invention, the upper tempered glass 212 has the iron content of the glass managed to be 150 ppm or less, and the solar light transmittance is increased due to the low iron content. Has.

The lower transparent back sheet 214 is made of a transparent material through which sunlight passes, and after sunlight that has not been condensed by the solar condensing cell 22 among the sunlight irradiated with the upper tempered glass 212 passes, Irradiated to the ground.

This lower transparent back sheet 214 has the advantage of being light in weight and easy to form, and further, it is cheap to reduce the production cost, and through this, it is possible to provide a solar module with high price/efficiency to both producers and consumers. There is an advantage to be able to.

Of course, in the present invention, the lower transparent back sheet 214 may be configured and disposed of the same material as the upper tempered glass described above, and any one selected from the above-described transparent back sheet or tempered glass may be used.

The body portion made as described above, such as thermal fusion, adhesive application, etc. in the state in which the upper POE, the lower POE, the upper tempered glass, the lower transparent back sheet, and the solar light collecting cell 22 disposed between the upper POE and the lower POE are arranged. It is integrally molded through various methods, and such a molding method can be variously changed according to the size and shape of the body part.

The photovoltaic condensing cells 22 are formed in a predetermined unit area and are arranged in a longitudinal direction and a transverse direction, and each of them is connected through an electric line.

These solar light collecting cells 22 are arranged at predetermined intervals from each other as shown, and the upper surface 221 directly condenses sunlight irradiated from the sun, and the lower surface 222 passes through the body part 21 After that, the reflected sunlight or sunlight reflected from the ground or water is collected after being irradiated around the body part 21.

That is, the solar light condensing cell 22 of the present invention condenses sunlight from the upper surface 221 and the lower surface 222, respectively, and thus has an advantage of increasing electricity production efficiency.
