Benefits of Solar Energy
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. The photovoltaic cells are gaining popularity as the size becomes smaller hence less materials are used in the production thus lowering the prices. 4oo 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 energy source makes no emissions into the environment and it only uses one of the most naturally available sources of energy. Solar cells are steadily finding a prominent place on house roofs across the world these days. They are uncomplicated devices to use for heating air and water within your home or to generate electricity. For heating water, water is first allowed to pass through the photovoltaic cells.
The photovoltaic technology has taken great strides. By engineering cells that can absorb sunlight on bright days and store it, it allows the cells to be functional even on days when the weather is cloudy.
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. By providing such a network, the PV system allows you to use a cheap environment friendly source of energy and itself works without much pressure on it. Some areas are designing centralized solar collection arrays for small towns or suburban communities.
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. Two notable examples are Google and Wal-Mart - while Google has installed a 1.6 MW solar power plant on the roof of its headquarters, Wal-Mart intends to use a 100 MW system that it will devise.
The American, German, Swiss and Japanese governments are among the few governments of the world that are providing tax breaks and subsidies to the individual persons or corporate entities that are using solar power for their thermal and electrical needs. Since technology is rapidly advancing making it possible to invent new methods of harnessing the vast reserves of solar energy for our purposes, it is only inevitable that private investors will see the benefits of this nature-friendly technology and provide further impetuses to its growth.
