Abstract

The invention provides a detection device for a photovoltaic system, the photovoltaic system, and an application method for the photovoltaic system. The detection device for the photovoltaic system comprises a box body and a circuit board arranged inside the box body, wherein the box body comprises an upper cover and a bottom case which form an accommodating cavity for accommodating the circuit board; a photoelectric detector is arranged on the circuit board; a translucent mirror is arranged on the upper cover and is relative to the photoelectric detector. The photovoltaic system comprises a plurality of photovoltaic components; each photovoltaic component is connected to a tracker used for tracking a sun light incidence angle; each tracker is connected with the detection device. The invention further provides the application method for the photovoltaic system. Through the system, the condition that the surfaces of the photovoltaic components absorb incident sunlight all the time can be ensured, so that within a limited lighting time, the power output of the photovoltaic components can be the highest, the utilization rate of the photovoltaic components is improved, and the production cost is reduced.

Description

technical field [0001] The invention relates to the field of photovoltaic cell production capacity, in particular to a detection device for a photovoltaic system, a photovoltaic system and a use method that allow sunlight to be incident on a photovoltaic cell at any time. Background technique [0002] With the development of society and science and technology, the production technology of solar photovoltaic cells has been continuously improved, and has been widely used in various fields. Solar photovoltaic cells (referred to as photovoltaic cells) are devices that directly convert light energy into electrical energy through the photoelectric effect or photochemical effect. It is a solar cell combination device with packaging and internal connection that can provide DC output alone, and solar photovoltaic cells are the core part of the solar power generation system and the most valuable part of the solar power generation system. Not only can the solar energy be converted int...

AI Technical Summary

Problems solved by technology

[0003] The electric energy generated by the battery mainly depends on the photon energy incident on the battery, but the current photovoltaic power generation products still have the problem of low power generation efficiency. The reason is that the current photovoltaic cells are generally planar, and the use of reflected light Rarely; secondly, the sun's illumination angle is always changing, and the flat and fixed-installed photovoltaic cells can only receive part of the light, and the received light is weak, so the utilization rate of photovoltaic cells will be extremely low. On the contrary, in order to improve the efficiency of power generation, the production cost will increase
