Problems solved by technology

However, in different seasons and different weathers, the time for the sun to rise and set is different. Using this method does not guarantee that the concentrating mirror or solar device is facing the sun every moment; and the power consumed by the motor is relatively large. , combined with 24-hour rotation, the energy consumption is serious

Abstract

The invention relates to the field of solar energy photovoltaic generating, and provides a solar energy photovoltaic generating automatic tracking system. The system comprises a solar module 1, a high-sensitivity light probe 10, a bottom supporting and fixing bracket 2, a solar module fixing bracket 9, a screw rod extending structure, a low-speed DC motor 5, and an automatic tracking controller. The automatic tracking controller makes judgment according to illumination signals acquired by the high-sensitivity light probe 10, and controls the low-speed DC motor 5 to rotate in the positive direction or the negative direction to drive a screw rod to extend, so that the solar module 1 is rotated around a fixed axle to achieve the tracking aim. The solar energy photovoltaic generating automatic tracking system has precise angle control and saves energy.

Description

technical field [0001] The invention relates to the field of solar photovoltaic power generation, in particular to an automatic tracking system for solar photovoltaic power generation. Background technique [0002] Generally, the solar cell components of the solar photovoltaic power generation system use a fixed angle to collect solar energy. Since the solar cell components are only facing the sun for a very small part of the day, the solar energy collected in a day is less and the power generation is low. [0003] The technical solution to this problem is to make a parabolic concentrating mirror rotate at a constant speed for 24 hours in the patent "Energy Concentrating Device that Can Automatically Track the Sun" (Patent No.: 91103247.9); The "solar device" (Patent No.: 01214070.8) directly rotates the solar device by 15 degrees per hour. However, in different seasons and different weathers, the time for the sun to rise and set is different. Using this method does not gua...
