Technology Information

Photovoltaic cells are shaped as black squares placed in the form of an array on a solar panel - although they were once quite expensive, the prices are gradually decreasing while efficiency is improving at focusing sunlight at a concentrated point. The simple black panels called photovoltaic cells can direct sunlight more efficiently and prices are lower, thus making solar energy supply the next possible energy revolution in the near future. 00 at the time of this writing. Just 17 years ago, the price was double what it is today.

Solar powered electricity generation is one of the best things that have happened to 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 steadily finding a prominent place on house roofs across the world these days. They are quite simple to use, whether you want to heat your home, heat water or generate electricity for the home. In order to heat water, the photovoltaic cells will allow water to flow into them, where it gets heated by the solar heat and then this hot water is passed through the pipes right into the home.

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. 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. Within some towns and suburban communities, such centralized solar collection arrays are becoming quite popular so that they can serve the entire region.

A number of multinational companies have expressed keen interests of entering into solar power generation, thus emphasizing how feasible and viable this source of energy is considered to be. 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 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. It is highly possible that private players will join into this fray soon because of the new technologies being designed to trap more and more of the solar energy in effective ways.
