Description

Cleaning Units and Distribution Assemblies for Solar Modules

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning apparatus for a solar module and a distribution assembly thereof, and more particularly, to efficiently clean and cool the surface of a solar module with a small amount of cooling water, and in particular, to supply cooling water supplied through a drain line. The present invention relates to a cleaning device and a distribution assembly for a solar module, which can prevent freezing caused by freezing of a drainage line in winter by natural drainage.

In recent years, photovoltaic power generation facilities are becoming unmanned and large in size, and installation of large-scale photovoltaic modules is essential for power generation. Therefore, places such as roofs, building walls, and parking lot roofs are difficult to access. Is selected.

Therefore, the photovoltaic power generation facility is exposed to the external environment for a long time, the amount of condensation is reduced by scattering dust, algae discharge, yellow dust and other pollutants.

In addition, the temperature rise of the photovoltaic module due to the condensation of the solar light causes a decrease in output of the photovoltaic power generation equipment.

In the case of the most widely used solar cell (Solar Cell), when the temperature of the solar module rises by 1 ° C, output decrease occurs by 0.4 ~ 0.5%, especially in summer, the temperature of the solar module is 70 ℃ or more As it rises up to 15-20%, the output is reduced.

In addition, in winter, snow accumulated on the surface of the solar module acts as one of the direct factors that reduce the power output of the solar module.

Therefore, the photovoltaic power generation facility uses the cooling power to cool down the temperature of the photovoltaic module and cleans or removes dirt, snow, and rain accumulated in the photovoltaic module so that the photovoltaic module can generate a constant output. It is also necessary to have facilities for maintaining the equipment.

Such a photovoltaic facility maintenance device includes a method of washing a solar module with a mechanical driving force such as a brush of a vehicle, a method of washing a solar module by connecting water hoses to the top of the solar module and flowing water, And there is a water injection method for washing the solar module by spraying water with strong water pressure through a separate nozzle.

The method of using the brush has to produce a separate brush suitable for the maintenance of the photovoltaic facility, and when the solar module is overheated, it does not provide a special method for cooling it.

Flowing water through the water hose has the disadvantage that it does not have a great effect on dirt removal or snow removal.

Therefore, the water spray method of washing the solar module by spraying water through the nozzle is efficient, but this method has a disadvantage in that water consumption is high because it has to spray water with strong water pressure. There is a limit.

In addition, in areas with a lot of snow in the winter, snow that does not melt due to snowfall in winter accumulates on the surface of the solar module, and thus the output of solar power is reduced, and there is a problem of freezing such as drainage lines due to the low temperature around the winter season. have.
