1. Solar Photovoltaic Power Systems

Solar photovoltaic systems play a vital role on economic growth of a region in relation to power availability and generation capacities because of the following:

(a) pollution free generation
(b) easy maintenance
(c) modular upgradation
(d) decentralized availability
(e) reduction in distribution costs

Though the photovoltaic systems are available they are expensive at present. Also they alone cannot successfully cater to the energy requirements without a very high efficiency balance of system design. The choice of balance of equipments is to be made carefully. Another major requirement is the storage of energy where in batteries of low maintenance and high recycling capacities must be used. Anup Kumar and Vaidehi (1991) compared a photovoltaic system with grid electricity system for village applications. They concluded that photovoltaic power plants are economically viable for providing electricity to villages situated at a distance of 10 kms or more from conventional grid supply lines. In most states such a situation does not exist. Thus photovoltaic power stations are not feasible at the moment though unlimited potential exists for the future.
