Sun Tracking Solar System

Abstract

In Pakistan we have an enormous demand of electricity in domestic and commercial areas. This huge demand must meet daily needs in economical way for public at all levels. Energy demand depends on size of population and level of activities. Energy production method must be efficient enough that maximum energy is extracted from source but also keeping cost of consumption as low as possible. Tracking systems are now being used in solar power plants to increase efficiency and to reduce costs. By properly positioning the PV panel in line with the exact location of the sun, the designed single axis solar tracker device ensures the optimum of solar energy conversion into electricity. The quantity of solar irradiation received by a photovoltaic (PV) system’s PV module decides the amount of generated electricity. Solar tracking, which provides for both the tracking of the sun on its daily and annual journey in the sky even while considering changes in cloud conditions, is one of the technical methods for increasing this amount and so enhancing the return on PV investments. The solar-tracking solutions that PV systems are most frequently equipped with deploy active sensor technologies, while passive ones are less common in present-day practice. The proposed single axis solar tracker device ensures the optimization of the conversion of solar energy into electricity by properly orienting the PV panel in accordance with the real position of the sun. Active sensor technologies are most commonly used in solar-tracking solutions for PV systems, while passive sensor technologies are less popular in today's operation. By correctly positioning the PV panel in line with the actual position of the sun, the designed single axis solar tracker device ensures the improvement of solar energy conversion into electricity.
