IOT-based Solar Tracking System for Efficient Power Generation

Abstract

Abstract

In remote areas the sun is a cheap source of electricity because instead of hydraulic generators it uses solar cells to produce electricity. But the output of solar cells depends on the intensity of sunlight and the angle of incidence. It means to get maximum efficiency; the solar panels must remain in front of the sun during the whole day. But due to the rotation of the earth, those panels can’t maintain their position always in front of the sun. This problem results in a decrease of their efficiency. So, to get a constant output, an automated system is to be required which should be capable to constantly rotate the solar panel. Automatic sun tracking system with photovoltaic plate to improve the efficiency of solar power generation was helpful to solve the problem, mentioned above. It is completely automatic and keeps the panel in front of the sun until that is visible. The unique feature of this system is that instead of taking the earth as its reference, it takes the sun as a guiding source. Its active sensors constantly monitor the sunlight and rotate the panel towards the direction where the intensity of sunlight is at maximum with the help of DC motor
