Solar Energy Collecting: An Alternative Source Of PowerAlternative energy has become increasingly popular with more people as it has become more economical. That is why there are more solar panels on homes and business than in the past. Photovoltaic cells, the black squares of a solar array, are not just becoming less costly, but also much more efficient. This has happened because through a more effective design, the gathered sunlight can be concentrated on a smaller area. The photovoltaic cells have become better, because they have become smaller and less costly to create. The cost per watt to make solar energy has been cut back by 50% fifty percent during the last twenty years.
For environmentalists, the nice thing about solar-powered energy production is that it emits absolutely no pollution. For some people, the greatest thing about solar power is the amount of money that can be saved on their electric and heating bill. As the saying goes, money talks and in this case, it is true because the adoption of solar power was the consequence of lower costs and not the greenhouse effect. There is no longer a barrier to put solar panels in a home because they've become very easy to set up.
The way hot water is produced is the water passes through an encasement of the photovoltaic cells, the water is heated then sent through the pipes. These cells, even on sunless days, are accumulating enough radiation from the sun much more efficiently. A company called Uni-Solar has developed solar collection arrays that can capture energy during inclement weather. This solar energy system has been advanced more technologically which allows more energy to be gathered during the days with sunlight. There is yet another popular solar power system known as PV. This system is connected to the electrical grid that is nearby, and transfers the extra energy to that grid for shared use. This helps to decrease the dependence of the grid on electric power from hydro-electric plants.
The main benefits of using a system like PV is reduced costs, decrease in the amount of pollution produced, and less dependence on the central grid system. There are small communities throughout the country that installed centralized solar collection arrays. Furthermore, many leading companies are using solar power as their primary source of power now. Google HQ is getting a 1.6 megawatt solar power plant on its roof, and even Wal Mart has plans of its own 100-megawatt solar power system.
Governments are helping the solar energy cause, with countries, including Germany, Japan, Switzerland and the United States, providing subsidies and tax breaks to individuals or businesses for generating electrical power with solar power. Numerous private investors also see the benefit of green energy and solar collection so they will continue to invest to ensure its future. As the adoption of solar energy becomes more and more popular, the prices will continue to go down, which could only benefit everyone.
