  • Solar energy, light and heat radiation from the Sun, has been exploited by humans since ancient times using a variety of technology development than ever before. Solar radiation along with secondary resources of energy like wind and solar energy, water power and biomass, make the most of renewable energy available on earth. Only a tiny fraction of the available solar energy is used.

  • Solar electric plants shall be understood to be photovoltaic energy converters that are able to self-sufficiently satisfy a mean energy demand over a significant period of time, be it an appliance that is permanently hooked up or just for sporadic power supply of appliances. Such plants have in common that their input and output quantities fluctuate widely. They can therefore only be dimensioned on the basis of a mean value and are not able to satisfy this demand without the possibility to store energy. ...

  • Grid-connected photovoltaic power systems are power systems energised by photovoltaic panels which are connected to the utility grid. Grid-connected photovoltaic power systems comprise of Photovoltaic panels, MPPT, solar inverters, power conditioning units and grid connection equipments. Unlike Stand-alone photovoltaic power systems these systems do not have batteries. When conditions are right, the grid-connected PV system supplies the excess power, beyond consumption by the connected load, to the utility grid.[1]...

  • With a global average irradiance of 342 W/m2, the Sun is by far the largest source of energy for planet Earth. In comparison, the internal energy produced by Earth itself is only about 0.087 W/m2 (Pollack et al., 1993), which in turn is 3.5 times larger than the 0.025 W/m2 of heat produced by the burning of fossil fuels. About 31% (31 units) of the solar energy which arrives at the top of the atmosphere is reflected back to space by scattering from clouds, aerosols, and the Earth’s surface. Almost 20 units of solar radiation are absorbed in the atmosphere....

  • East and Southern Europe), India, parts of South America, Southwest U.S./northern Mexico and Australia. The operating characteristics of STPPs are relatively well matched with the intermediate and peak electricity load requirements in these regions. Two types of collectors have been used in STPPs: parabolic trough and central receiver. Electricity is generated by incorporating the solar collectors with a Rankine cycle power plant or as an add-on to a natural gas combined cycle (referred to as an ISCCS).
