In general, energy consumption in each country is increasing every year, and greenhouse gas emissions from energy use are also increasing rapidly in proportion to energy consumption. Therefore, the development of eco-friendly alternative energy has become a major concern in the energy conservation policy of each country, and the need and importance of alternative energy development is gaining weight as the year progresses.

In recent years, development of energy technology using solar energy, which is pollution-free and relatively easy to secure the energy source, has been actively researched and used among the alternative energy. This solar energy is a technology (photoelectric effect) that converts sunlight directly into electric energy, and consists of a module type solar cell, a battery, and a power inverter. In other words, through this configuration, a clean energy source using sunlight can be used indefinitely.

Therefore, even when the specialist installs the apparatus, the construction time is long and the workability is deteriorated.

Korean Patent No. 10-1302311 discloses a method of improving the structure of the profile constituting the support frame so that the support frame and the support frame can be easily joined to each other with a bolt and a nut by using a bonding material. There is no structure in which a solar cell can be installed on a support frame. Therefore, in order to install a solar cell on a support frame, a separate C-shaped pipe or another member must be used. Therefore, the installation cost and construction cost increase, have.

The support frame 500 may be fixedly mounted on the ground surface of the place where the solar cell 10 is to be installed using a normal installation method. Therefore, a detailed description will be omitted.

Next, after the installation of the support frame 500 is completed, the inclined stage 700 and the inclined stage fixing bracket 800 are prepared. Then, the upper end of the inclined stage 700 is fixed to the lower portion of the support frame structure via the inclined stage fixing bracket 800 And the lower end of the inclined stage 700 is fixed to the support frame 500 so that the inclined stage 700 supports the inclined supporting frame structure firmly.

That is, the upper end of the ramp 700 and the ramp fixing bracket 800 are fixed by the bolts B and the nuts which are inserted through the bracket coupling holes 810 and the inclined plate coupling holes 710, The fixing bracket 800 and the supporting frame 100 may be fixed through the connecting fixing member 300 inserted into the coupling groove 120 of the supporting frame 100 through the bracket elongated hole 820. [ Here, the connection fixing member 300 may be used for connecting the support frames 100 to each other. For the operation and the installation method, reference should be made to the above description. The ramp 700 and the support frame 500 may be fixed by a conventional bolt (B) and nut (N) method. This completes all installation tasks.

If the solar cell 10 is installed by applying the solar cell structure installation method, all the parts can be assembled without welding, so that the workability is good and the construction time can be shortened. Further, since the structure of the solar cell structure support is improved, the installation workability is greatly improved, and excellent workability and workability are obtained. Particularly, since the supporting frame 100 is improved in structure and connected to each other by the supporting frame 100 itself, not only the supporting frame structure is formed, but also the battery fixing member 400 It is possible to reduce the unit cost of the solar cell 10, and as a result, the overall installation cost can be reduced.

While the present invention has been particularly shown and described with reference to specific embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. Anyone who can afford it will know.
