A comprehensive solar electric system for remote areas

In the year 1882, in London, the Edison Company first produced electricity that could be delivered to the customers via a distribution Grid or Network. Since then electricity has become a necessary energy sources for domestic use. However, in the majority of the world developing countries it is estimated that less than 5% of the rural population are connected to the national grid. There are many technical and economic reasons for that. However, if utility lines are needed and not available at some important remote areas. Solar electric systems can provide the required electricity sources. In general, electricity are produced by converting an energy source into mechanical shaft power, which in turn drives a generator which produces electricity. Where solar system convert sunlight directly into electricity with no moving parts, or maintenance, which is free and safe, and clean energy with no fuel and with no ambient pollution. This is the most environmentally way to produce power directly from sunlight to produce electricity for most household needs. The amount of power a solar electric system can collect depends on the natural energy resources at the applied location and on the equipment installed to gather that energy. The social impact of introducing solar electricity to remote areas is enormous. There are the obvious benefits of improved social services and cover the need of electricity. There are also less obvious benefits. The introduction of electricity often helps to create productive employment in rural areas and reduce immigration and there is a positive impact on economic as well as social growth. The main object of this paper to investigate the solar electric system. The comprehensive system consists of PV array, inverter, voltage regulator, battery and battery charger. The inverter, the regulator and the battery charger have been widely studied. A useful discussion also has been included.
