Your Guide to Solar Energy

By Lucille Green

Photovoltaic cells are increasing in efficiency, but decreasing in cost although they are still the same old black squares placed on solar panels in an array format, but now they are able to concentrate energy to a particular point in a much better manner. They are also becoming smaller in size and this is what's making them cheaper to produce despite the fact that their efficiency is increasing. The price of solar power energy is tagged at pr watt per hour at this time of writing. Just 17 years ago, the expense for getting the same performance was about , double what it is today.

There's definite benefit in using electricity generated from the sun for the environment. Solar energy uses the most natural of sources for its production: the sun which releases no harmful emissions into the environment and is considered to be an excellent alternative source of energy. Solar cells are today very popular fixtures on people's home rooftops. They are uncomplicated devices to use for heating air and water within your home or to generate electricity. There it gets heated and is then supplied inside the home through pipes.

It is possible to gather heat from the sun even in stormy and cloudy weather with modern photovoltaic cells. This technology operates by making the cells to gather more of the suns rays on bright days which can be used in adverse conditions.A solar cell manufacturer known as Uni-Solar allows you to have solar energy even on overcast days.

The PV system is another kind of solar power system. A connection is made of the PV system to the nearest grid of electricity and when a particular home produces more energy using the solar cell, this excess energy is sent off to the grid so now the grid will use this energy for electricity production.

The best benefits of using PV systems are that you are getting solar power inexpensively, you are using a source of energy that is in accordance with the environment and you are freeing up the pressure on the grid. Town planning in some areas today includes setting up central solar accumulation arrays so that this energy could be available for the entire town.

Several reputed corporations have indicated their deep interest into solar energy production on a large scale and this clearly shows how the world is accepting solar power as a sustainable source of energy. 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.

The subsidies and tax benefits provided by the governments of US, Japan, Germany and Switzerland among other countries to people or to corporate entities that install and use solar power plants for their purposes are helping to further popularize this concept. By checking out the new inventions in the solar trapping technology, new investors will want to cash in on the technology and make profits with it and this will only bring in more popularity to solar power generation.
