Today in this modern world the rise in living standard and population has generated a major problem in front of this modern world, which is energy crisis. Due to continuous growth of living standard and population at a rapid rate the problem is getting to be worse in few years from today. The conventional energy sources are depleting at a very fast rate. Due to which the need of generating power from non- conventional energy sources has increased to meet the growing demands of this modern world. Out of many non-conventional energy resources solar energy, which is cheap and available in abundance is being used to meet the situation. The book is a step in field of harvesting non-conventional energy resource (Solar Energy) with the help of Solar flat plate collectors.
