In the context of growing emission of carbon dioxide in coal-based power stations, solar energy promises to be a viable alternative and a clean energy source. Yet, the market for solar energy remains small and uneconomic, confined as the system is to households in remote villages and delinked from the network of electricity grids. If provided a direct link to the electricity grids which are served by thermal power systems, solar power systems can achieve economies of scale and can ultimately provide for the larger market of demand for electricity in the country.
