Description

Solar cell modules with angle adjusting part

The present invention relates to an angle-variable solar cell module, and more particularly, it is possible to adjust the angle of the solar cell module mounted on the cradle according to the change in the concentration of the light depending on the season. The present invention relates to an angle-variable solar cell module that allows the light to be positioned in the best direction to greatly improve the light collecting efficiency and power production compared to the same light collecting time, and to facilitate replacement and repair of solar cells.

In general, as fossil fuels such as coal are depleted, development of alternative energy using solar light, solar heat, or wind power is progressing, and energy resource development utilizing solar energy is being actively performed.

Power generation technologies that produce electricity using solar energy include solar power generation that generates electricity by driving heat engines using solar heat, and solar power generation that generates electricity from solar cells using sunlight.

In addition, a solar cell used for photovoltaic power generation is mainly made of silicon and a composite material, and uses a photoelectric effect of generating electricity by bonding sunlight to a P-type semiconductor and an N-type semiconductor.

These solar cells are classified into crystalline silicon, thin film type, and next generation (organic, fuel-sensitive, and bare structure), and can be classified into silicon based and compound semiconductor based on raw materials. It is regular and the arrangement direction is constant, so there is no jam in the electron movement, so the conversion efficiency is high.

In the crystalline silicon solar cell manufacturing process, the ore (silica, sand) containing silicon is refined in an electric furnace to make polysilicon. Polysilicon is placed in a quartz crucible and impurities (boron or phosphorus) are put together to melt at high temperature to form columnar crystalline silicon ingots, which are then thinly cut to about 200 μm to form a mono / polycrystalline silicon wafer.

After the pn contact is formed on the monocrystalline / polycrystalline silicon wafer thus formed, the upper and lower electrodes are formed so that the internal current flows out and the anti-reflective coating is applied to reduce the reflectance of the light. Is completed.

In addition, a solar cell is called a cell (minimum unit), and practically no solar cell is used as it is, and a plurality of cells are packaged to protect a plurality of solar cells connected in a required unit capacity in a harsh environment. It is composed of solar cell module and used.

On the other hand, such a solar cell module is mounted on a cradle that is usually provided inclined bar, because the solar cell module mounted on the cradle is installed in a fixed state, the installation angle is kept fixed, depending on the season There is a problem that the concentration of electricity is changed due to the south middle altitude of the sun, the efficiency of electricity production.

That is, in the spring and autumn, the solar cell module should maintain an angle of about 36 degrees, and in summer, the solar cell module should have an angle of 45 degrees so that the light condensation by the solar cell module will appear most efficiently. Since the modular body is fixed as it is, once installed, there is a problem in that the amount of light is reduced by season and the light is poor.

In order to solve such a problem, a conventional solar cell module angle adjusting device has been conceived, which is installed under one side edge of the solar cell module body and has one side of the solar cell module body. And a support unit for supporting the lifting unit and a lifting unit installed at the lower side of the edge of the solar cell module facing the support unit to lift and lift the other side of the solar cell module body at an angle corresponding to the incident angle of sunlight. The battery module body can be rotated automatically while being uniformly balanced, and the rotation angle of the solar cell module body is not changed by external force.

However, the conventional technology not only makes the configuration complicated, but also requires the automatic elevating of the angle of the solar cell module by the elevating unit, which greatly reduces the installability and replaces the elevating unit in the event of a malfunction of the elevating unit. There is a problem in that additional costs are incurred.

In addition, when the conventional solar cell module is broken, it is difficult to replace or repair the solar cell module because it is necessary to assemble the solar cell module again after replacing the solar cell after the failure. .
