Systems of PhotoVoltaic Solar Generation There are two systems of electric power generation from solar cells : Roof top array system Satellite system 1. Roof Top Array System : This system is mounted on roofs. It is an earth based solar system. In such system the problem of energy storage is difficult. But the solution … Read more
Properties of Biogas Even at very low temperature the biogas readily mixes with air. So It does not need to provide rich mixture at starting time. It has very good antiknock properties. It is a safe fuel. Uses : Biogas can be used in petrol engines, diesel engines as a fuel for cooking, for power … Read more
Advantages and Disadvantages of Solar Thermal Power Plants Advantages of Solar Thermal Power Plants (Over other Conventional Thermal Power Plants) The process of energy conversion is pollution free. No fossil fuel is required (so saving in fuels). No transportation of fuels as coal (oil transportation in conventional plants). It can be erected at convenient/remote areas. … Read more
