However, the angle of the solar high-light incident on the surface of the photovoltaic module is different, as the incident angle is increased, the light transmittance is gradually reduced, and the less solar energy is absorbed by the photovoltaic module, the larger the relative transmittance is lost, so that the angle of the photovoltaic array needs to be adjusted according to the different angles of the solar high-light.
For a photovoltaic array installed at a common fixed inclination angle, in order to reduce the relative transmittance lost in one year, according to the solar altitude angle throughout the four seasons, an adjustable bracket is used for dividing the year into two parts each half year in winter and summer, and the inclination angle of a photovoltaic module is adjusted twice, for example, the inclination angle of the photovoltaic module is adjusted down in summer, and the inclination angle of the photovoltaic module is adjusted up in winter, and the sun is tracked by an optical sensor, so that the aim of improving the relative transmittance is fulfilled. The solar energy tracking system can also be adjusted four times per year according to the optimal inclination angles corresponding to four seasons of spring, summer, autumn and winter, and particularly can be adjusted according to the actual conditions of solar irradiance and solar altitude angle of each month, and the sun is tracked through the optical sensor.
