The commercially available tracking systems make use of servomotors with feedback controllers, and add substantially to the overall cost of a solar energy system. They also require a power supply, and a sophisticated level of maintenance. Since the Solar energy devices are important for applications in decentralized systems, which are usually located in remote and rural areas, these two requirements are often not met. Consequently, tracking is normally dispensed with. Full story
