Description
Technical Field
The invention relates to the technical field of solar power generation, in particular to a sun position tracking method for photovoltaic power generation.
Background
The solar cell panel directly or indirectly converts solar radiation energy into electric energy through a photoelectric effect or a photochemical effect mainly by absorbing sunlight. That is, the more solar radiation the solar panel receives, the more electric energy can be converted, so the output power of the solar module depends on factors such as solar irradiance and the like. At present, solar cell panel is because fixed mounting, and the sun removes in solar cell panel's top, because the sun is at the in-process that removes, can remove to solar cell panel's side, removes the solar meeting slope irradiation at solar cell panel side on solar cell panel, and the slope is shone and is reduced solar cell panel to the absorption of sunlight easily, influences the conversion of electric energy.
Currently, chinese patent ZL200510094900.8 discloses a sun tracking device and a tracking method based on tracking posture feedback. The tracking method comprises the steps of calculating local sun value and time difference by using longitude, value and date and time, calculating a sun azimuth angle and an altitude angle in real time according to the longitude, value, sun value, time difference and time, driving a motor to rotate by using an altitude sensor and an azimuth sensor, and realizing real-time tracking by using closed-loop control. The tracking method can accurately track the position of the sun theoretically, but in the actual situation, due to the thickness of the earth atmosphere layer, sunlight can be refracted when entering the atmosphere layer, so that the incident angle of the sun is changed, and the refraction effect can cause great errors on active tracking illumination. The other is a passive tracking method, and chinese patent 201210004997.9 discloses a method for automatically tracking sun rays and an automatic tracking system. The tracking method utilizes two groups of photoelectric sensors to collect illumination intensity, and the controller drives the motor to rotate towards the sun according to the collected illumination difference value, so that the sun is tracked in real time. The disadvantage of this tracking method is that the general photosensitive devices have large photosensitive error; in addition, the photosensitive element is often covered by dust, so that the photosensitive capability of the photosensitive element is weakened; or when the two photosensors are contaminated to different degrees, their outputs will form an inherent error that can be very large for passive tracking.

firstly, the structure is complex, the action response of the solar cell panel is slow, and great errors are easily generated when sunlight is actively tracked;
second, solar cell panel is moving behind the west falling following the sun, solar cell panel has just stopped in the direction that the sun descends, and the sun just rises in the morning of the next day, because solar cell panel's orientation is in the direction that the sun descends, and solar cell panel's back is towards the direction that the sun rises, can shelter from the photosensitive element of solar cell panel surface partly, when causing the sun just to rise in the second day, solar cell panel can't accurately track to the initial direction of sun, influence solar cell panel at the all-weather absorption solar energy of daytime.
