The present invention relates to a system for optimizing installation of solar energy using facilities that can be installed at altitude and azimuth that can achieve a maximum annual efficiency of solar power and solar heat collectors fixedly installed.

Recently, due to serious environmental problems such as climate change convention and abnormal temperature phenomenon, various technologies are being developed and commercialized. Among alternative energy, solar energy is spotlighted as pollution-free and environmentally friendly energy, and installation capacity is increasing rapidly in developed countries. In recent years, large-scale power generation projects have a large installation area, which brings new problems to the environment and land use.

The methods of solar power generation can be largely classified into fixed and tracking types, and the fixed type means fixing the solar power plant according to the altitude and azimuth angle that can absorb the most solar energy during the year, and the tracking type is the altitude of the sun. It means keeping track of angles and azimuths so that the photovoltaic plant has the highest efficiency. In terms of efficiency, the tracking type is 20 ~ 40% higher than the fixed type, but the installation cost is relatively higher than the fixed type and fixed type is mainly installed due to the difficulty of maintenance. In addition, the increasing number of building integrated solar installations replace roofs, walls, and windows, so tracking applications are almost impossible.

Since these fixed solar installations are fixed all year round, it is important to install the altitude and azimuth at the angle that will give the best efficiency throughout the year.

However, conventionally, solar installations are installed at the altitude and azimuth angles presented based on the locally measured solar radiation, and there is no facility to measure accurate altitude and azimuth angles at the time of installation. Many do not develop into. Moreover, in the case of the integrated building type, the installation elevation angle and the azimuth angle are closely related to the appearance of the building, and thus, economic analysis through advance prediction of power generation is more important than most because there is no related equipment.

The object of the present invention devised to solve the above problems of the prior art is the optimal installation altitude and azimuth angle information of solar installations using a global database of solar radiation, temperature, clarity, GPS, latitude, longitude and electronic compass After installation, it is possible to verify the altitude and azimuth angle after installation, and the installation optimization system of the solar energy utilization equipment that can calculate the power generation amount, installation area, and current generation amount information according to the installation angle based on the amount of power required and solar cell information To provide.

And a communication unit for exchanging information between the CPU and the user's computer.

Hereinafter, with reference to the accompanying drawings will be described in detail the installation optimization system of the solar energy utilization equipment according to an embodiment of the present invention.

Figure 1 shows a picture of the installation optimization system of the solar energy utilization equipment as an embodiment of the present invention. The installation optimization system of the solar energy utilization facility is composed of a tripod 200 supporting the installation optimization system main body 100 of the solar energy utilization facility and the installation optimization system main body 100 of the solar energy utilization facility.

The second display unit 112 of FIG. 2 has six red LEDs (LEDs) at the left and right, one green LED at the center, six red LEDs at the top and bottom, and one green LED at the center and one green LED at the center, respectively. It consists of white LEDs, one green LED on the left and six red LEDs on the left and right to indicate the difference between the optimal installation azimuth and the current azimuth, and the difference between the center and the center of the center when the difference between the optimal installation and the current azimuth is less than 1 degree Green LEDs emit light (ON, ON), and when the LEDs exceed the red LEDs, the red LEDs emit light sequentially. One green LED and six red LEDs on the top and bottom display the difference between the optimal installation altitude and the current altitude, and the two green LEDs in the center emit light when the difference between the optimal installation altitude and the current altitude is less than 1 degree. If it is more than that, the red LEDs are sequentially emitted according to the angle difference. If the error of optimal installation altitude, azimuth and current altitude and azimuth is less than 1 degree, all the red and green LEDs up, down, left and right will be off and only the center white LED will be on. . Based on the center white LED indicating azimuth and altitude, 7 LEDs (6 red and 1 green) and 7 LEDs (6 red and 1 green) are arranged respectively. It is turned on based on the error level of optimum angle and present angle as shown in the following table.

Adjusting the direction and altitude in the direction in which the LEDs of the second display unit 112 are turned on (ON) reduces the error and reduces the number of LEDs that are turned on (ON). 'S white LEDs are turned on and all red and green LEDs are turned off.
