The present invention relates to a vibration-absorbing solar power frame support device, and more particularly, to easily and stably installed through the frame and the support device on the plate when installing the light collecting cells for solar power, wind pressure, etc. It relates to a vibration-absorbing solar power frame support device that can absorb the vibration when it occurs.

In general, photovoltaic power generation is to collect electrical light through incident light collecting cells to obtain electrical energy.

The sun, as a blackbody of the effective surface is so 5762K solar expansion angle between the emitted and the energy of the 6.25X107W / m ² of the earth and the sun is 0.27 degree irradiation reaching outside the earth's atmosphere is 1370 W / m ² and about Clarity It is known that the amount of insolation that reaches Earth in the sun is about 800-1000 W / m ² .

Since the energy density is low in order to use the above solar energy as it is, in order to obtain a high temperature from the solar energy, it is necessary to track the position of the sun to efficiently collect the low-density sunlight to increase the density of the sun. The condensing method can be presented in various ways depending on the type of sunlight to be collected.

As an example, a photovoltaic power generation system for condensing sunlight by arranging a plurality of them in a rectangular condensing cell type has been widely used.

For photovoltaic power generation, the essential components such as solar array, inverter that converts direct current generated from solar cell into alternating current, and balance of system such as battery for rain or snow lasting several days are essential. In the daytime, solar-generated electricity is used for home appliances and surplus electricity is sent to utility companies through grid lines.

In other words, photovoltaic power generation is a power generation method that converts sunlight directly into electricity. The core of the photovoltaic power generation is a solar cell (Solar Cell or Photovoltaic Cell). When sunlight with energy greater than Eg (Band-gap Energy) is incident, electron-hole pairs are generated.The electron-holes are gathered into n-layer and holes into p-layer by the electric field formed at the pn junction. As a result, electromotive force (photovoltage) is generated between pn. At this time, if the load is connected to the electrodes at both ends, the current flows.

These solar cells can be connected in series and parallel as needed to make a structure that can withstand the natural environment and external shocks for a long time. The minimum unit is called a photovoltaic module, and the module is arrayed according to the actual load. It is installed in the form of (Photovoltaic Array). However, solar cells not only generate electricity during the day and night when sunlight, rain, or clouds are exposed to sunlight, but also generate a non-uniform direct current according to the intensity of the solar radiation.

As a result, a general photovoltaic power generation system includes a solar cell array (condensing cell) in which solar panels are connected in parallel and a power storage battery, a power regulator, and a cross-flow converter (inverter) in order to supply power to a consumer. Peripheral devices are essential.

When the photovoltaic power generation system is installed outdoors, when a wind pressure or the like is generated, a vibration phenomenon occurs, and the vibration is transmitted to the plate-shaped light collecting cell, thereby shortening the service life of the expensive light collecting cell.
