Solar Power Technology (Energy Flow Conversion) Solar energy from sun is collected by different types of solar collectors of various shapes and sizes or collected by using solar ponds. This solar energy is transferred directly to the working fluid or through heat exchanger. The steam is formed. Its pressure is much more. This high pressure … Read more

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
