The present invention is an invention the applicant has issued a circle Application No. 10-2017-0078521 favor continuous improvement used. The existing lateral system to install solar cell panels for solar power generation on earth (Horizontal system) is a problem that spacious land required and you cannot build a solar power plant to replace the nuclear power plant in this narrow country area of land this because the present invention using the abandoned slopes inclining a large-scale solar power plant in abandoned increase the multi-stage installation longitudinally system (vertical system) land-use efficiency by providing an apparatus and method for a plurality of solar cell panels in a vertical longitudinal Mountain It relates to an effective method of construction and its application system unit.
The existing method of installing solar cell modules above ground requires a broad land area because solar cell panels are installed horizontally. Because the average installation area is about 10 m2 including the service area, a land area of 14,000,000 m2 is required in order to construct photovoltaic system of 140 MW (based on Kori 5 nuclear power plant), which is practically impossible because the area exceeds about 1400 hectare.
When solar cell panels are installed under the existing method on a flatland, solar cell panels are installed by adjusting or remotely controlling the panel frame slope composed of a number of solar cells. The method, however, requires a broad area of land because frames need distance in order to prevent frames shading each other due to the high height of panels.
In addition, the existing flatland installation method cannot be implemented correctly when the installation is made on steep mountain areas, which leads to the difficulty of maintenance and repair, in addition to the need for installing heavy solar cells on a mountain slope, causing solar cell panels to be easily damaged or destroyed due to the strong wind on mountain slopes.
In addition, the existing solar cell panel installation method on mountain slopes has the issue of being able to use only the south side of a mountain. As such, an effective solarcell installation method that utilizes all sides of a mountain from the south side as well as the north, east, and west sides.
The existing solar cell panel installation system is a prefabricated mount that consists of fixed-type whereby the reflection angles of panels are fixed and installed and variable-type of free adjustment of panel slopes among panels.
The apparatus registered under the Korean Patent No. 10-1108713 (Photovoltaic system with ease of gradient adjustment) used hinges to connect a solar cell mount with solar cell panels and changed the gradient of the hinge axis, which, however, had the issue of damaging the panels when strong wind or the weight the solar panel itself caused the panels to fall backward.
Under the Korean Patent No. 10-1670346 (Photovoltaic system for scarfed roof installation), the upper frame that supports solar cell panels and the lower frame that supports the upper frame is composed in the form of assembly and the gradients of the panels are fixed and installed. However, the problem of the impossibility of free adjustment of gradient persists.
Under the Korean Patent No. 10-0887723 (Floating fixation structure for sunlight collection panel), a floating structure for installing sunlight collection panels on the river or lake is patented. However, there is a problem that the power generation cost is twice as high compared with the existing thermal power generation due to the high installation cost.
Under the U.S. Pat. No. 6,060,658 (Pole having solar cells), the specified technology constructs a street map being operated by the power supply from a solar cell module that is installed on the 360 degrees surface of a pole. However, the power generation efficiency is low because no consideration is given to the angle of the slope or direction of the panel that collects sunlight.
Under the U.S. Pat. No. 8,776,454B2 (Solar array support structure mounting rail and method of installation thereof), solar cell panel mounting methods of using rails are specified. However, the method still requires a broad land area because solar cell panels are mounted on rails that are installed horizontally.
In 1954, Bell Labs recorded 4% of efficiency with silicon (Si) solar cells, which has been improved to around 15% as the efficiency of mass-produced cells is achieved by improving the manufacturing process and purity of raw materials. The emergence of the metal oxide perovskite in 2012 increased the mass production efficiency over 22% and reduced the manufacturing cost could be lowered to 1/3 or less of silicon solar cells.
Accordingly, the Grid Parity, which means the cost of photovoltaic power generation required for generating 1 KW of electricity becomes equal to that of fossil fuel-based general power generation, has already been reached. However, the difficulty of securing large areas of land for constructing large scale photovoltaic power stations that can replace fossil fuel-based power generation systems persists.
In countries worldwide, it is recognized that nuclear power generation based on nuclear division is vulnerable to earthquakes, and nuclear power plants may be bombed in wartime, causing damage in the size of an atomic bomb. Accordingly, for example, Israel has never installed nuclear power plants, and the tendency to avoid nuclear power is increasing in countries where there is a danger of war or terrorism.
In addition, power stations using coal-based thermal power generation are being closed down by many countries due to the pollution issue. Thus, a groundbreaking system must be developed to provide industrial photovoltaic power generation technology that replaces thermal or nuclear power generation while reducing the generation cost.
Existing solar cell panels had the problem of increasing generation costs due to land prices. In addition, the resistance against panel reflections created difficulties in constructing photovoltaic power generation systems of large scale in cities.
Due to the aforementioned problems, some countries are experimenting with installing photovoltaic power generation facilities on the floor of salt fields or on roads. As a solution, a method of installing solar cell panels on mountain areas is being suggested. However, because the only south side of mountain areas can be used, a technology that can utilize all sides of inexpensive mountain areas should be developed.
This invention provides effective and economical method and system apparatus of installing large scale solar cell panels for photovoltaic power generation on slopes of all sides (east, west, south, north) of abandoned mountains in order to reduce photovoltaic power generation cost and aims at providing large scale photovoltaic power generation facility establishment technology that replace thermal power generation stations by using mountains.
In order to achieve the aforementioned purposes, this invention improves the existing solar cell panel installation method in the horizontal direction into the installation in a vertical direction and thereby provides system technology and methods that dramatically reduce the installation area compared to existing methods.
In addition, this invention provides the technology that enables the construction of large scale photovoltaic power generation stations that utilize all sides of slopes of an abandoned mountain by installing solar panels vertically.

However, this invention enables solar panels to be installed on a tower-shaped steel structure and thereby provides useful technology that allows solar panels to be installed without being restricted by the direction of a mountain slope.
Moreover, the existing mountain slope installation method included the difficulty of installing large-sized and heavy solar cell panels on rugged mountain terrain. However, this invention provides effective ways to install or mount by hoisting up and down heavy solar cell panels with an alternating or direct current motor winch on a rail.
This invention provides an effective and economical solution of installing large amounts of solar cell panels regardless of the direction or gradient of mountain slopes and thereby has the effect of significantly reducing photovoltaic power generation cost because of the land price of the mountain slopes is significantly cheaper than that of flatland or farmland.
This invention is in the structure of fastening the four axes of solar cell panels on a slope. Thus, this invention has the effect of maintaining the optimal power generation efficiency because the method is safer against strong wind compared to the existing rotational

When a connection tool is constructed that can adjust the length between rails from selective 2 sides from 4 sides (up, down, left, right) of the solar cell panel frame, the gradient of each frame can be adjusted up and down or left and right directions.
In addition, when a motorized or hydrodynamic connection tool is constructed that adjusts the length between rails on the left and right sides of the upper side as well as lower side of the frame, it can be constructed to allow varying angle and slope of the frame by 360 degrees by adjusting the length of each connection tool based on remote control.
