Analysis of Power-Efficient High Torque Solar Tracker through PID Controller

To provide a continuous supply of electricity, renewable energy resources, and smart technological innovation must be exploited, aiming to provide a long-term solution to the existing energy crises faced by today's world. The photovoltaic (PV) panels are deployed to receive solar energy from the sunlight and consequently convert it into electrical energy. The photovoltaic PV panel receives maximum solar radiation only when it is at 90° perpendicular to the sunlight, which is directly proportional efficiency of the system. If proper technique not used to collect the maximum amount of sunlight, solar PV generation can be a more expensive energy source as compared to conventional energy generation. The generated output power of PV panels depends on the quantity of solar energy they collect from sunlight, and this amount can be increased by exploiting tracking systems. The solar tracker tends to move PV panels perpendicular to sunlight radiations to collect the maximum amount of sunlight to increase the system's efficiency.
