Solid state regulator/charger for low power PV systems

Abstract

The different types of electronic regulator battery chargers employed in low-rating solar-powered lighting systems are discussed. A low-power photovoltaic (PV) lighting unit was built and tested which includes a basic constant-current series regulator interfacing with the PV module and the storage battery. The system is especially designed for use in remote areas to serve small farming communities. The system has proved to be practical, low in cost, and reliable.<>
