									Photovoltaic
The technologies used in photovoltaic systems are well developed and there have been
improvements as well modification which occurs regularly, primarily on production processes. These
systems are reliable and are well-tested in terrestrial and space uses.
The number one obstacle to boost the application of photovoltaic system is the high initial cost of
these items. Continuous price reduction was occurring. On some off grid locations like two quarter
miles, systems could be cost effective to the cost of the running power line into property and
subsequent continued electric charges.
Some systems, including the electric utility of Austin, are established PV-centralized power station,
and many more are including the “green power” option that allows the customers to pay small fee with
their utility bill per month which would be used to build additional renewable energy installation (wind,
biomass, PV etc.) with the aim of adding more renewable energy outlets for the overall energy of
City’s production base. But, of greater awareness to homeowner is the decentralized PV systems’
potential located in residences providing power the home as well as the centralized grid power when
the PV power overmatches the requirements of the homes. The power grids provide power to homes
when the PVs aren’t producing power.
The electric power generation option has been now beginning to be compared in a basis which
includes the “externalities.” These externalities are “hidden” costs linked with the power sources that
aren’t accounted for on the price of power made. The hidden cost includes damage to environment
made by the processing, transporting, using, sourcing and even the disposal aspects of the power
source. Operational costs as well as the externalities linked with the usual fuel mix (oil, nuclear, coal,
natural gas) utilized for generating electricity aren’t substantially less than “full” costs linked with the
photovoltaic system and, in lots of cases, overmatch the costs of the PVs. Use of PVs has been much
less harmful than other fuel choice.
The use of the PVs as electrical power outlet for a home is minimizing the need for the use of
electricity. Refrigerators, electric water heaters, air cons, electric ranges, clothes washers and electric
dryers are all large consumers of electricity. The highly energy conserving alternative and gas
appliances have been available to reduce the electrical loads greatly.
PV is a way of generating the electrical power by altering the solar radiation in to direct current
electricity utilizing semiconductors that exhibits the solcelleanl?g effects. The photo voltaic power
generator employs the solar panels made up several numbers of solar cells having the materials.
These materials presently used in photovoltaics include the monocrystalline silicon, amorphous
silicon, polycrystalline silicon, copper indium and cadmium telluride gallium sulfide/ selenide. Because
of the growing demand in renewable energy source, the production of solar cells as well as arrays
has been advancing considerably on recent years.
Solar photovoltaic is now, after the wind and the hydro power, the 3rd most important renewable
source of energy in terms of worldwide installed capacity.
