Abstract

The invention relates to the technical field of solar energy, in particular to a solar orientation detection device and a solar tracking method for a photovoltaic system. A sun detection device for a photovoltaic system includes a photosensitive device, a processor, a clock chip, a detection circuit and a processing circuit. The photosensitive device of the present invention uses a plurality of photoresistors, which increases the sensitivity of sunlight detection and the precision of solar panel adjustment. A clock chip is added to the system, which can calculate the general orientation of the sun according to the current time, and adjust the photosensitive device to avoid the problem that the photosensitive device cannot receive the sun's rays due to the opposite direction of the photosensitive device and the sun's rays. When it is night according to the time calculation, the photosensitive device can be automatically turned back to the rising position of the sun, and the system can be dormant to achieve energy saving effect.

Description

technical field [0001] The invention relates to the technical field of solar energy, in particular to a method for tracking sunlight. Background technique [0002] Solar energy is a kind of clean energy. In the photovoltaic system that uses solar panels to receive sunlight for power generation, the installation orientation of the solar photosensitive plate of the original solar receiving device is fixed. Due to the rotation of the earth, the sunlight affects the solar photosensitive plate at different times. The angle of incidence is different, and the charging efficiency of the solar cell is the best when the sun's rays are perpendicular to the photosensitive plate. Therefore, calibrating the orientation of the solar photosensitive panel according to the incident angle of sunlight can effectively improve the charging efficiency of the solar cell and improve the utilization rate of the equipment. [0003] The traditional photoelectric tracking uses 4 photosensitive devices ...
