Requirements for batteries in remote-area power-supply systems based on technical modelling and field experience

The development photovoltaic/diesel remote-area power supply (RAPS) systems and their structural emplacement in developing countries are discussed. Key areas of importance are identified as economic returns for RAPS systems and the need for centralized control and collection of data. The value of photovoltaic modules as a power source and techniques for maximizing the energy input to batteries from this source are explained.
