IoT-based Solar Panel Tracking System to Enhance the Output Power

In today’s world, power takes an important role in day-to-day life. Power is generated by using different natural resources like light, wind, and water. From the sun, light energy is converted into power with the use of solar panels. Wind energy is converted into power by using a windmill. Hydro energy from water can be converted into power. So, power can be generated with the use of natural resources. By using the solar panel, the light emitting from the sun is converted into power and that power can be used for many purposes. Solar panels can be seen in tall buildings like schools, colleges, offices, and industries. And solar panels can be implemented where the sunlight falls like a terrace in houses, terraces in buildings, and can be on Highway roads. But the sunlight cannot be falling all the time at the same place where the solar panel is implemented in a stable state. So, to observe the light from the sun all the time, Solar Panel Tracking System is implemented based on the domain of the Internet of Things (IoT). With the use of Light Dependent Resistors (LDR), Voltage sensor, Current sensor, Servo motor, NodeMCU, and ThingSpeak Cloud is applied for Solar Panel Tracking System. LDR senses the light from the sun, the Servo motor is used to rotate the panel,and the Voltage and Current sensorssense the voltage and current from the panel for converting to power. NodeMCU configures the sensors and motor and to the cloud. ThingSpeak cloud displays the values of the data.
