This book covers fundamentals of Solar Energy.Application of Solar Energy in Agricultural Sectors as well as Transporation Sector..Comparison Solar Energy with Wind Energy.Advantages and Disadvantages of Solar Panels.In the long run, solar power saves money. Initial costs of installation and operations may be more expensive that other energy forms but after settling the expenses, you have an energy resource that is free. Nobody charges for using sunlight, right? The return of investment can also be shorter depending on how much energy you use. You won't spend too much on maintenance etc. There are no mechanical or moving parts to oil and maintain nor are there parts that need to be replaced yearly. Of course solar power is environmental friendly. First its renewable not like fossil fuels which according to studies will be gone in four to five decades.The process of converting energy to usable electricity does not involve the release of toxic chemicals which can harm the environment. Carbon dioxide, nitrogen oxide, sulphur dioxide, lead, and mercury emissions will be a memory of the past when everyone goes solar. Relying on the sun for power also helps reduce global warming
