Alternative energy has become moe and more popular with more people because it has become more economical. A good example is the solar array, which is now on many homes and businesses. The black squares on solar panels, referred to as photovoltaic cells, have become affordable and more efficient to use. Due to advancement in technology, these cells can collect the energy from the sun in a smaller area. These solar cells have become very useful as they can now be made at smaller sizes and at lower cost. The cost per watt to make solar power has been cut down by 50% fifty percent during the last twenty years.
For environmentalists, the nice thing about solar-powered energy generation is that it gives off absolutely no pollution. For a lot of us, solar energy can help us save a great deal of money on our electric and heating bill. The only reason why solar power has become popular is that it is cheap to use, not because of concern for the environment. Also setting these solar arrays on your rooftop is no longer hard to do, which also helped in the rapid growth.
The way hot water is produced is the water goes through an encasement of the photovoltaic cells, the water is heated then sent through the pipes. The photovoltaic cells have become clever enough to gather enough radiation from the sun even on overcast days. There is a company called Uni-Solar that created solar collection arrays that work during stormy weather. This system is created as such when during sunny days, energy is stored in huge amounts in case inclement whether comes around. There is yet another popular solar power system referred to as PV. It allows a home to share its excess electricity to the electrical grid in a residential area. The result is less reliance on electric plants and lower electrical prices.
The benefits of the PV System are taking pressure off of the grid system, along with reducing pollution, and reducing your costs too. There are small residential areas all over the country that designed centralized solar collection arrays. An indication that solar power is becoming an acceptable alternative energy option is that several big-name companies are getting into solar energy. Google has been employing a 1.6 megawatt system to power its offices and Wal Mart is developing their own 100 megawatt system using solar energy to power their stores.
Governments are providing aid to the solar energy cause, with countries, including Germany, Japan, Switzerland and the United States, offering subsidies and tax breaks to individuals or companies for creating electrical power using solar power. Private investors will go on to see the value of investing in eco-friendly technology, as technological advances continue to increase solar collection materials. As more and more individuals use it, the cost will continue to go down.
