REAL TIME CLOCK BASED ON OPTIMUM POWER SUN TRACKING ENERGY SYSTEM

This project deals with an RTC based solar tracker though it is single axis the main advantage of this solar tracker is its low cost of manufacturing as no sensor has been added. It also accurately follows the sun so that sunlight remains perpendicular to the panel most of the time. So it can be implemented anywhere. One of the most striking features of this prototype is that it is an open loop circuit, thus it is stable and robust and will not get affected by noise or other distortions. Since LDR or other power consuming circuits are not used so we get power draw from the circuit is less. The power extracted from RTC is 15-22% greater than that of conventional fixed systems. Although it is lesser than a double axis solar tracker. But we have minimized the power consumed by a large DC motor or servo motor that is required for moving the solar panel in accordance with azimuthal angle, the used prototype can be easily created for Solar Panels having a rating up to a range of 15 W, but for solar panel, with the larger rating, the construction design and motor use will change. Applications of this prototype can be used for solar charging of any equipment and street lighting.
