Alternative energy has gotten increasingly popular with more people since it has become more cost-effective. That is one reason why you find more solar arrays on more houses and businesses. The black squares on solar panels, called solar cells, have become affordable and more efficient to use. This has happened because through a more effective design, the gathered sunlight can now be concentrated on a smaller area. These cells have become very useful because they can now be manufactured at smaller sizes and at lower cost. The cost per watt to create solar power has been cut in half over the last 20 years.
For environmentalists, the nice thing about solar-powered energy production is that it gives off absolutely no pollution. For others, the best thing about solar power is the amount of money that can be saved on their electric bill. As that old adage goes, money talks and in this case, it is true since the adoption of solar power was the result of lower costs and not the greenhouse effect. But now the collection cells are a practical way for heating one's house, being easy to place on rooftops, they are no longer hard to use.
The way hot water is created is the water goes through an encasement of the photovoltaic cells, the water is heated then sent through the pipes. The solar cells have become efficient enough to collect energy on cloudy days. A company named Uni-Solar has developed solar collection arrays that can capture energy during stormy weather. This system has been advanced more technologically which allows more energy to be gathered during the days with sunlight. There is one other popular solar energy system referred to as PV. It allows a home to share its surplus electricity to the electrical grid in a community. This is to reduce the dependence of the grid on electricity from hydro-electric plants.

Hence, the huge benefits of employing the PV system is less dependence on the grid, decreasing pollution and reducing energy costs. There are small communities all over the country that have centralized solar collection arrays. An indication that solar power is becoming a desirable alternative energy choice is that several large companies are getting into solar energy. Google has been utilizing a 1.6 megawatt system to power its offices and Wal Mart is creating their own 100 megawatt system using solar energy to power their stores.
Governments in countries like Japan, Germany, Switzerland and the United States are providing people tax breaks to utilize solar energy for their houses or businesses. Investors will go on to see the value of investing in eco-friendly technology, as technological advances go on to increase solar collection materials. As this happens, the cost will keep decreasing, benefiting the local owner.
