Usefulness of solar energy in today's world.

By Ben V. Williams

The once expensive photovoltaic cells can now be obtained at a lower price as the process of producing them becomes easier and faster. These are produced at larger quantities and are smaller I size, thus making them possible for a reliable source of energy supply on a mass scale in the bear future. The prices have lowered to per watt per hour. 17 years ago, the price was doubled.

There's no question about how environment-friendly solar powered electricity generation is. This is an alternative form of energy production that does not emit any hazardous material into the environment and uses something that is naturally available as its source.

Today, solar cells are abundantly found on the rooftops of people's homes. You can use them without much trouble in heating your home, heating water and in producing power for all your needs . There it gets heated and is then supplied inside the home through pipes.

Photovoltaic cells of today enable you to gather heat from the sun and store it even if the sky is full of clouds or if there is a storm brewing. The technology used by Uni-Solar is an example of it.

In addition to the above system, there's another system available known as the PV system. The system is attached to the closest grid of electricity so if a home produces more electricity by its solar system, this energy is channeled into the grid, which can now utilize this energy for electricity production and will not have to depend wholly on hydroelectricity.

Using PV systems makes solar energy production economical for you, and also mitigates the problem of environmental pollution and helps to free up the grid from excessive pressure. Within some towns and suburban communities, such centralized solar collection arrays are becoming quite popular so that they can serve the entire region.

Worldwide, there has been an active interest among large scale corporations to enter into the arena of solar power generation and among other things, it shows how feasible this concept is. Google has already installed a 1.6 MW solar power generation plant on the roof of its headquarters while Wal-Mart will soon outdo this by installing a 100 MW solar power system of its own.

Countries such as Japan, Germany, Switzerland and America are providing benefits such as subsidies and tax deductions to people - whether individuals or companies - who install solar power systems for getting their supply of thermal and electrical power. This kind of interest will only help make it more and more popular and ultimately - affordable!
