Abstract

The invention discloses a solar slit tracking device which comprises a stepper motor used for driving a solar panel to rotate, an optical signal acquisition device comprising a plurality of photosensors, an encoding system and a singlechip. The encoding system comprises an encoder group, an AND gate group connected with the encoder group and the singlechip, and an encoding device connected with the encoder group; and the singlechip is also connected with the stepper motor. The singlechip computes encoding signals output by the encoding device to obtain the specific encoder which outputs low level; and the singlechip computes received electrical signals output by the encoding device and the AND gate group to obtain the specific number of a photosensitive diode which is irradiated by sunlight so as to order the stepper motor to rotate a stepping angel. The solar slit tracking device enables solar cells to track the sun in real time to improve the utilization efficiency of solar energy.

Description

technical field [0001] The invention relates to the field of photovoltaic technology, in particular to a solar slit tracking device. Background technique [0002] With the increasingly prominent energy and environmental issues, the development and utilization of renewable energy has gradually attracted the attention of the world. Solar energy has become a fast-growing renewable energy due to its cleanness, wide distribution range, and convenient utilization. Solar photovoltaic power generation is one of the main forms of solar energy utilization, but due to the high price of solar panels, the cost of photovoltaic power generation remains high, thus restricting the development of solar photovoltaic power generation industry. Therefore, how to improve the utilization efficiency of solar energy and reduce the cost of solar energy utilization has become a hot spot of people's research at present. [0003] Figure 5 Describe the movement of the sun throughout the day and the ch...
