Solar Energy
About Photovoltaic
photovoltaic
  • Photovoltaic (PV) systems convert light energy directly into electricity.
  • Commonly known as “solar cells.”
  • PV represents one of the most promising means of maintaining our energy intensive standard of living while not contributing to global warming and pollution.
  • Sunlight is composed of photons, or bundles of radiant energy. When photons strike a PV cell, they may be reflected or absorbed (transmitted through the cell). Only the absorbed photons generate electricity. When the photons are absorbed, the energy of the photons is transferred to electrons in the atoms of the solar cell.
  • Solar cells are usually made of two thin pieces of silicon, the substance that makes up sand and the second most common substance on earth.
  • One piece of silicon has a small amount of boron added to it, which gives it a tendency to attract electrons. It is called the p-layer because of its positive tendency.
  • The other piece of silicon has a small amount of phosphorous added to it, giving it an excess of free electrons. This is called the n-layer because it has a tendency to give up negatively charged electrons.
WHY SOLAR ?
  • Saving diesel fuel consumption to an extent of solar generation.
  • Saving with respect to costs incurred to buy diesel fuel for running generator sets.
  • Saving with respect to costs incurred on buying electricity from the local discom.
  • Saving with respect to buying expensive energy from 3rd party suppliers.
  • Become energy secured for future.
  • Give space for future generations to breath, start generating green power.
Best place for solar panels
  • South Facing roof, adequate space
  • No shading (time of year, future tree growth)
  • Roof structure, condition
