Solar tracking controller for photovoltaic power generation

Abstract

The invention provides a solar tracking controller for photovoltaic power generation, and belongs to the technical field of photovoltaic power generation. The problem that in the prior art, the energy utilization rate is low is solved. The solar tracking controller for photovoltaic power generation comprises a control module, a photoelectric detection module and an execution device, the photoelectric detection module comprises a photosensitive array, a photoelectric sensor and a voltage comparator, the photoelectric sensor is used for identifying daytime or night, the photosensitive array adopts four same photosensitive resistors which are symmetrically arranged on the execution device up, down, left and right, and is used for sensing illumination intensities in the upper direction, the lower direction, the left direction and the right direction respectively, the light intensities are converted into voltages, and the four paths are independently compared through the voltage comparator; and the execution device comprises a base, a pitching angle adjusting structure, a horizontal angle adjusting structure and a frame used for installing the solar photovoltaic module, and the photosensitive array is arranged on the frame. The solar tracking controller has the advantage that more solar energy can be collected in a limited use area.

Description

technical field [0001] The invention belongs to the technical field of photovoltaic power generation, and relates to a solar tracking controller for photovoltaic power generation. Background technique [0002] With the enhancement of environmental protection awareness and the hidden worries of energy crisis, various researches on solar energy applications have received much attention. There are two ways of solar energy utilization: photothermal conversion and photoelectric conversion. Solar power generation is a new renewable energy source with broad prospects. . [0003] In solar power generation technology, the installation of solar panels is uniform, easy to manage, and will not increase additional system costs and many other advantages. However, the incident direction of the sun's rays always has a certain degree of angular deviation from the solar panel array, and vertical incidence The time is too short, which leads to low efficiency of the photovoltaic power generati...
