Description

[0001] Solar Heat Collection Device for Apartment House [0002]

The present invention relates to a solar collecting apparatus for a residential house that obtains hot water from solar heat and solar light for power generation. More specifically, the invention relates to a solar collecting apparatus for collecting solar heat, To a solar collecting apparatus for a residential house.

Solar cells, which convert solar energy into electrical energy, are rich in energy resources and have a low risk of environmental pollution. They are becoming a substitute for alternative energy sources such as petroleum and coal. Such a solar cell may have a structure in which modules composed of two or more cells are arranged in a certain form.

Generally, the conversion efficiency of the solar cell is about 10% to 20%, and the solar energy which can not be converted into the electric energy is converted into heat and the temperature of the solar cell is raised. For example, if the power generation efficiency at 25 ° C is assumed to be 100%, a power reduction of 0.45% to 0.55% occurs at every 1 ° C rise in temperature of the solar cell .

That is, the temperature and the voltage of the solar cell are inversely proportional to each other. When the temperature of the solar cell rises, the voltage decreases and the power generation output decreases. As the temperature of the solar cell module deteriorates, There is a problem that the lifetime of the solar cell is shortened due to deterioration.
