Development of Solar Tracking Technique to Maximize PV system output with the sensor

All forms of energy can be traced back to the sun's energy. The sun's rays can be utilized in a variety of ways, of which the generation of electricity and thermal energy are the major ones. Photovoltaic (PV) cells have become the industry standard in the solar power sector. Elements such as solar radiation, ambient temperature, and wind speed have a great impact on solar cell performance. The panel loses most of the energy it receives by converting it into heat, which is always dissipated. The reason for carrying out the research is to analyze the PV system performance upon tracking the sun. An Arduino Nano microcontroller, a servo motor, a light-dependent resistor (LDR) sensor, etc., were all part of the system. The amount of radiation detected by the LDR sensor was used to determine the servo motor's output speed. The proposed system was tested experimentally, and the results exhibited a 32.5% increase in power gain over the fixed solar panel, which is 7.3% more than the existing model. Additionally, this study provides a graphical comparison of the output voltage and efficiency with the existing system.
