Description

Remote management of photovoltaic efficiency improvement facilities {METHOD OF REMOTELY CONTROLLING EFFICIENCY ENHANCEMENT EQUIPMENT FOR SOLAR PHOTOVOLTAIC POWER FACILITIES}

The present invention relates to a remote management method of a solar power efficiency improving equipment, and more particularly, it is possible to effectively manage a plurality of solar power equipment efficiency improving apparatus, which is required for management and operation of solar power equipment users. It is about remote management of photovoltaic efficiency improvement facilities that can save cost and time and provide management operators with new revenue sources.

Generally, the method of using solar energy is largely divided into a method using solar heat and a method using solar light. The method of using solar heat is to heat and generate electricity using water heated by the sun, and the method of using solar light can generate electricity by using the light of the sun to operate various machines and appliances. It is called solar power.

In the above-described method, the photovoltaic effect in which photovoltaic power generation is caused by electron-hole electromotive force generated by light energy when irradiating sunlight to a pn junction photovoltaic panel with n-type doping on a silicon crystal. Generate electricity using

To this end, a solar cell for condensing sunlight, a photovoltaic module that is an assembly of solar cells, and a solar array in which the solar cells are constantly arranged are required.

Unlike conventional energy sources such as fossil raw materials, sunlight is a clean energy source without the risks of greenhouse gas emissions, noise, and environmental degradation that cause global warming, and there is no fear of exhaustion. In addition, unlike other wind and sea power, solar power plants have the advantage of free installation and low maintenance costs.

However, in the case of the most widely used silicon solar cell, when the temperature of the photovoltaic module rises, output decrease of 0.5% per 1 ° C occurs. According to these characteristics, the output of solar power peaks in spring and autumn, not in the summer when the sun is the longest. This increase in temperature is a major cause of lowering the power generation efficiency of photovoltaic power generation.

In addition, the photovoltaic module has a disadvantage that dirt may easily accumulate on the solar panel due to meteorological phenomena such as yellow sand and bad weather. If dirt accumulates on the photovoltaic module, the light absorption rate of the photovoltaic module is significantly reduced, and thus the power generation efficiency may also be reduced.

In addition, when rain or snow falls on the solar panel in winter, a decrease in power generation efficiency may occur. In order to prevent the deterioration of power generation efficiency caused by dirt, snow, and rain, a photovoltaic power plant maintenance device is used.

The injection amount of can be reduced gradually. In order to adjust the cooling water spray direction, the injection time of the cooling water injection, the stop time of stopping the cooling water injection, or the injection speed of the cooling water may be adjusted.
