Alternative energy has become more popular with more people as it has become more affordable. That is one reason why you will observe more solar arrays on more homes and businesses. Photovoltaic cells, the black squares of a solar array, are not just becoming less expensive, but also much more efficient. This has come about because through a more effective design, the accumulated sunlight can now be concentrated on a smaller area. These solar cells have become very useful as they can now be made at smaller sizes and at lower cost. In the last twenty years, the cost per watt hour for producing solar-generated energy, has been essentially cut back by fifty percent.
For environmentalists, the nice thing about solar-powered energy generation is that it gives out absolutely no pollution. For others, the best thing about solar power is the amount of money that can be saved on their electric and heating bill. As that old adage goes, money talks and in this case, it is true as the adoption of solar energy was the consequence of lower costs and not the greenhouse effect. But now the collection cells are a practical way for heating one’s home, being easy to put on rooftops, they are no longer a difficult system to use.
Hot water is produced when the water goes through the photovoltaic cells and is heated up, then it passes through the pipes. These photovoltaic cells, even on cloudy days, are collecting enough radiation from the sun much more efficiently. The solar arrays, which have been developed by one certain company called Uni-Solar, work on severe days. This technology is advanced where more energy can be collected during sunny days to make up for days when there is limited sunlight. There is one other solar power system known as PV that people are using. It allows a home to hook up to an electrical grid and share any surplus power to the grid. The result is less dependency on electric plants and lower electric prices.
The main benefits of using a system like PV is lower costs, reduction in the amount of pollution created, and less reliance on the central grid system. There is a growing trend in a lot of residential areas and suburbs where they are putting their own centralized solar collection arrays. On top of that, many leading companies are utilizing solar energy as their main source of power instantly. The corporate headquarters of Google is getting a 1.6 megawatt solar power plant on its roof, and even Wal Mart plans to install its own 100-megawatt solar power system.
Governments in countries like Japan, Germany, Switzerland and the United States are providing people tax incentives to utilize solar energy for their houses or businesses. Many private investors also see the benefit of green energy and solar collection so they will continue to invest to ensure its future. As more and more people use it, the cost will continue to fall.
