Abstract

The invention provides a photovoltaic panel position optimizing and adjusting system. The system comprises a voltage detector, a controller, a motor driver, a stepping motor, a rolling bearing, a supporting frame, a first photovoltaic panel and a second photovoltaic panel. According to the invention, a relation model of a photovoltaic differential pressure model, stepping motor steering and maximum power output is constructed; and the controller obtains a motor steering control signal according to the photovoltaic voltage difference and the voltage threshold, further generates a motor pulse control signal in combination with PI adjustment, and transmits the two signals to the motor driver. The motor driver performs current amplification on the motor steering control signal and the motor pulse control signal to obtain a motor steering and corner driving signal, and transmits the motor steering and corner driving signal to the stepping motor; and the stepping motor rotates the rolling bearing according to a motor driving signal, so that a movable solar panel is driven to rotate according to the supporting frame. The system is high in energy utilization rate and good in stability andreliability.

Description

technical field [0001] The invention belongs to the technical field of new energy power supply, and in particular relates to a photovoltaic panel position optimization adjustment system. Background technique [0002] In the 21st century, solar energy will become one of the main energy sources in the world, and it is the most primitive energy source. Almost all other energy sources on the earth come directly or indirectly from solar energy. Solar energy has the advantages of abundant resources, longevity, wide distribution, safety, cleanliness, and reliable technology. [0003] Photovoltaic power generation is a power generation method in which solar panels directly convert light energy into electrical energy. It is the mainstream of solar power generation today. According to the survey, the photoelectric conversion efficiency of monocrystalline silicon solar cells is about 15%, and the highest can reach 23%. The photoelectric conversion efficiency is the highest, but its ma...
