Using solar energy for homes

Using solar energy for homes

Solar energy has been used in ancient times for heating houses .c ' after the discovery of the photoelectric effect and the invention of the steam powered by solar energy that people began to think of solar power for execution of simple household machines, used for heating purposes in addition to engine.

The need to use solar houses has been seriously considered in the 20th century when he realized that fossil fuels (coal, oil and gas) are not unlimited and that electricity will be more difficult to generate economically in the future when using solar houses offers also little serious impact on the environment.

Uses of solar energy for homes

Solar energy can be used at home for various fins.Ils are mainly used for small, low-power radio stations, lighting design, gadgets, pumps devices running small water and even children's toys. Solar energy can also be stored in batteries and used to illuminate the House for an episode of courant.Et failure, of course, solar energy is increasingly used for heating of houses during the winter.

How Home Solar Power Systems effective?

To use solar power for homes, photovoltaic (PV) panels is fixed on the roof of a House as their extended surfaces are South facing for houses in the hemisphere Nord.Pour those in the southern hemisphere, panels face North to collect solar maximum.

Average power of solar cell production is approximately 11 to 22 watts per square foot.When solar energy received by panels, generates an electrical current in eux.Ce current is stored in a large battery bank is connected to the PV array through a controller charger.Stored in the battery DC current is converted in current AC (used in homes) by a DC - AC inverter to race home equipment.

Odds against using solar energy for homes

Major drawback which interferes with the use of solar energy for homes is the high cost of purchasing and installing .According size House and particular solar system, on average, 000 cost in, 000 to install a home solar power system.

The costs of solar panels at home is due to the requirement of the use of pure silicon in their fabrication.Récemment however, solar-grade silicon has been derived from the metallurgical Silicon.

This innovation is intended to reduce the costs of the installation of solar energy systems at home to approximately one-third cost actuels.outre a high cost, solar panels are not very useful in areas of little sun and cloudy days also after the sunset.
