Study of Low Cost and High Efficiency Intelligent Dual-Axis Solar Panel System

摘要

Over the past few decades, the energy crisis has been one of the main problems in third world countries such as Pakistan. Among them, there is still a big gap between the amount of power generation and the actual social energy demand. For example, in Pakistan, as there is no electricity transmission and as a result, some scholars have suggested that renewable energy may be the only solution to this problem. Among all renewable energy sources, solar energy is one of the most efficient and easiest renewable energy sources to use. And can play an important role in resolving these crises. This can easily cause shadows and reduce power generation efficiency. The proposed method controls the power plant and cleans the photovoltaic surface if necessary. This work is divided into two parts, namely: hardware and software systems. On the hardware side, four light-related resistors (LDRs) are used to detect the best source of sunlight. Two servo motors were also used to move the solar panel to the maximum light source position detected by LDR. In the software part, this code is written in the programming language C. and transferred to the Arduino UNO controller. When the dust sensor detects dust in the air, the controller will be used to control the speed of the dust removal activity by the electric brush. In addition, the proposed method compares the characteristics of solar panels with and without the proposed method. The results show that the dual-axis rotation mechanism and the dust removal ability effectively maintain the performance of the solar cell panel and the effect of dust accumulation after the dual-axis rotation.
