Construction and operation of a solar lighting system

Abstract

A solar lighting system which can make a 3w lamp glow continuously for about one hour if the battery is fully charged has been constructed. The device can be used for small-scale lighting applications in remote areas that are far away from the power grid. The system has a panel to collect the sun’s energy, a battery to store that energy and a light source to use the energy. The system operates like a bank account. Withdrawals from the battery to power the
light source must be compensated for by commensurate deposits of energy form the solar panels.
