Solar Home Lighting System with AC and DC Loads

Abstract

The main objective of the study is to provide alternate lightning system by using solar energy. The system taken for study consists of a Solar panel of 10W, a 12 V battery, a Solar charge controller, Multi vibrator IC(CD 4047),MOSFET(IRF Z44N),Step down transformer(12-0-12). It provides solution to the gap between energy demand and energy availability. The charge controller maintain the flow of charge to the battery i.e, it provides protection against the overcharging and deep discharging of the battery. At the same time PV technology is the strongest growing electricity generation technology, which also provides a solution to the global warming. Almost every portion of the tropical India is favorable for adopting this technology. PV energy is being used across the world with different conversion technologies as autonomous power packs and as grid-integrated systems. Type of converter and load depends on the application to which it is intended. The study presents the analysis of solar powered home lighting system practically and verifies the design of the system for reliable and optimal performance.
