Automated hybrid solar and mains system for peak time power demand

摘要: A solar system using PV arrays to convert radiation into direct current was a preferred renewable energy source compared others. Fluctuations in commercial grid power supply depended greatly on peak demand load. It was, therefore, more convincing utilise array meet time demand. In this paper the design of hybrid mains and is discussed; completely automatic through an selector with pre-scheduled panel cleaning use microcontroller. LCD displays selection provides for overriding selection; manual switching included. During demand, and/or battery would be used; at other times will source. Moreover, emergency or during failure also provided. The MPPT controlling PWM signal boost converter achieve maximum output discussed. automated makes it user-friendly. Although initial costs are high, could reduce load grids
