Comparative Analysis of Parabolic Trough Solar Water Heater by Using Different Reflectors with and without Glass Cover
Abstract: Abstract All forms of energy on earth are derived from solar energy, so it is the primary source. Demand of energy consumption in today’s era is increasing continuously; this puts the burden on our conventional energy sources like coal, petroleum, natural gas etc. which are limited and can exhaust in future if not managed by alternate sources. So, use of solar energy for various energy generation processes is best option …
