Solar Power Collecting: An Alternative Source Of EnergyDue to its gradual cost-effectiveness, alternative energy has become extremely popular in a lot of areas of the world. That is why there are more solar panels on houses and business than in the past. The black squares on solar panels, known as photovoltaic cells, have become affordable and more efficient to use. This has happened because through better design, the collected sunlight can now be concentrated on a smaller area. So the solar cells have become very productive in their use because of their smaller size and lower cost of production. The cost per watt to create solar energy has been cut down by 50% fifty percent during the last 20 years.
What a lot of environmentalists like about using solar energy is that it produces no pollution. For most of us, solar power can help us save a lot of money on our electric and heating bill. As the old saying goes, money talks and in this case, it is true as the use of solar power was the result of lower costs and not the greenhouse effect. There is no longer a barrier to install solar arrays in a home since they've become really easy to set up.
To create hot water by utilizing solar cells, the water is heated while it is inside the cells, and then sent through your pipes. The solar cells have become clever enough to collect enough radiation from the sun even on sunless days. The solar arrays, which have been developed by one certain company called Uni-Solar, work on stormy days. This technology is advanced where more energy can be gathered during sunny days to make up for days when sunlight is limited. There is yet another popular system called PV. It allows a home to hook up to an electrical grid and share any excess power to the grid. This helps to lower the dependence of the grid on electric power from hydro-electric plants.
The main benefits of employing a system like PV is reduced costs, decrease in the amount of pollution made, and less dependence on the central grid system. There is a growing trend in many towns and suburbs where they are installing their own centralized solar collection arrays. Evidence of solar energy becoming a recognized energy source is its use in a lot of big companies. Google has been employing a 1.6 megawatt system to power its offices and Wal Mart is creating their own 100 megawatt system 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 benefits to individuals or companies for creating electrical power with solar energy. Investors also see the value in promoting eco-friendly technology and will continue to invest money into it. As more and more people use it, the cost will continue to go down.
