The Sun is a reliable, non-polluting and inexhaustible source of energy. Since the beginning of life on earth, the energy that was received by all living forms was radiated from the sun. It is the time now when the mankind is on a standpoint to again depend and rely upon the sun as the main source of energy.
With rapid rise in energy prices, concern over pollution, depletion of resources and environment degradation the awareness for limited resources around the world has increased dramatically. Use of fossil fuels which causes green house emissions, inefficient use of energy and release of harmful pollutants to the atmosphere causing threat such as acid rain must be addressed seriously in new buildings. Governments with vision have come to realise that generation of electrical power through non renewable sources of energy is not enough. The power of the future must be environmentally friendly as well.
Photovoltaic is a way by which energy from the sun can be directly used for power generation. This method for electricity generation causes no environmental pollution, has no rotating or moving parts, and causes no material depletion. Photovoltaics are also multifunctional. It can generate and operate illuminations, pump water, operate any house hold equipments and appliances, can operate any electrical gadgets and communication equipment. The photovoltaic finds its wide application in village electrification in the developing countries and electricity production for the buildings, commercial areas and industrial sector in cities.
BIPV, a segment of the growing Photovoltaic (PV) market, is becoming a popular way to generate electricity by the use of solar energy. Building integrated photovoltaic (BIPV) projects uses nearly 50% of world production of solar PV cells. However, we in India are yet to initiate the promotion of BIPV.
