Abstract

The invention discloses a slit tracking method for solar energy. The method comprises the following steps: initializing parameters; detecting whether a low-level signal is input into a singlechip from the priority encoding work logo output end of an encoding system by the single chip; assigning a value to P, namely P equals to 0; calculating a specific serial number of a photosensitive device which is irradiated by light; detecting whether the value of the P is equal to that of M by the single chip; sending (P-M) stepping angle orders for controlling a stepping motor to perform clockwise rotation by the single chip; and after finishing executing the order, assigning the value of the P to the M, namely M equals to P. The invention is the slit tracking method for the solar energy, which enables a solar cell to track the sun in real time so as to improve the utilization efficiency of the solar energy.

Description

technical field [0001] The invention relates to the field of photovoltaic technology, in particular to a solar slit tracking method. Background technique [0002] With the increasingly prominent energy and environmental problems, the development and utilization of renewable energy has gradually attracted the attention of the world. Solar energy has become a rapidly developing renewable energy due to its cleanliness, wide distribution and convenient utilization. Solar photovoltaic power generation is one of the main forms of solar energy utilization. However, due to the high price of solar panels, the cost of photovoltaic power generation remains high, thus restricting the development of the 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 research hotspot. Figure 8 Describe the movement of the sun throughout the day and the changes in the sun's orb...
