Abstract

The invention discloses a double-photoelectric-sensor combination control sun tracking method which comprises two steps of roughly tracking and fine tracking. In the invention, the large-range sun position catching is realized through a rough tracking photoelectric sensor module so as to achieve the rough tracking of a condensation rack; and the sun position fine catching is realized through a fine tracking photoelectric sensor module so as to achieve the sun fine tracking of the condensation rack. The problems of low tracking precision of a coder and tracking limit of a single photoelectric sensor are solved by adopting a double-photoelectric-sensor combination control sun tracker. The invention has the advantages of large tracking range, high tracking precision, easy manufacture, low cost and high cost performance. The invention also discloses a double-photoelectric-sensor combination control sun tracking device.

Description

technical field [0001] The invention relates to the technical field of solar energy utilization, in particular to a dual photoelectric sensor joint control sun tracking method and a device thereof. Background technique [0002] Solar energy is a clean and pollution-free renewable energy, inexhaustible and inexhaustible. Fully exploiting solar energy can not only save the increasingly depleted conventional energy, alleviate the severe shortage of resources, but also reduce pollution and protect human beings. ecological environment for survival. Among many solar energy utilization technologies, solar photovoltaic power generation technology realizes the direct conversion of solar energy into electric energy, which is the most convenient way of utilization. It has the characteristics of safe and reliable operation, no fuel, no noise, no pollution, local utilization, It is easy to use and maintain, and the scale can be large or small, so it has been valued by countries all over...
