Abstract

The invention discloses a method for tracking solar energy by slits, which comprises that: parameters are initiated; a singlechip detects whether a priority coding working mark output end of a coding system outputs low level signals to the singlechip; P is assigned with a value 0, namely P=0; serial numbers of photosensitive devices illuminated by light are calculated; the singlechip detects whether the value of P is equal to a value of M; and the singlechip sends a command of controlling a stepping motor to positively rotate P minus M stepping angles, and after the command is executed, the value of P is assigned to M, namely M=P. The method for tracking the solar energy by the slits can make solar batteries to timely track the sun to improve the solar energy utilization efficiency.

Description

technical field [0001] The invention relates to the field of photovoltaic technology, in particular to a method for tracking solar energy by a slit. 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] Existing programmable tracking systems for tracking the ...
