Solar energy is that produced by the sun''s light. It is one of the largest renewable resources which is used for various domestic and industrial purposes like cooking, dehydration, drying, heating power generation etc. and available almost everywhere.

Concentrating solar power (CSP) plants are currently designed with either cooling towers or air-cooled condensers. These two alternatives have a trade off: cooling tower evaporative cooling systems use water, which is a scarce resource in the desert environments where CSP is implemented, but air-cooling results in decreased power plant performance.
