Solar energy is the use sunís already existing energy to generate power and heat for many different applications. These days the technology is on the forefront of renewable energy and itís constantly expanding as only a fraction of the sunís energy that hits the earth is being used. This type of energy has been used for centuries to provide heat and lighting to all sorts of human endeavors. Currently the technology around harnessing this energy is growing in leaps and bounds as new inventions create greater efficiency that is not only used for large commercial applications, but also for peoples own homes. Equipment for home solar panels, pool solar panels and other ground breaking residential solar panels used for harnessing the sunís rays, are now readily available and practical sources of energy for homes and businesses.
Using solar power comes in two different forms: passive and active. The former has been used for centuries to help heat buildings and use the sun for providing light. It involves the skillful placing of buildings and construction methods that allow light and heat to enter buildings. Many of these methods, discovered over centuries of building construction, have been naturally incorporated into modern building design. In recent years, more flexible solar panels have been developed in order to improve on these standards to create greater energy efficiency and comfort by adapting to the path of the sun and a homeís local terrain.
The active form is where high-tech innovations are happening right now and helping to provide an alternative source of energy. Solar panels are the most common and popular form of these innovations. Once very inefficient, these devices have now become a viable convertor of the sunís rays into energy. They work very similar to how plants leaves operate, except using electronic equipment called photovoltaics. Large panels of photovoltaics have been used to create large solar power plants in many of the hot and dry areas of the world, where the sun constantly shines. Additionally, small solar panels are installed on devices as tiny as calculators and garden lighting to provide free power to these products.
Other advanced technology, focuses rays from the sun to provide intense levels of heat and energy. This technology and other solar panel kits are still in testing, but it is one of many technologies that make use of solar energy. Additional technology that uses solar waves is also be used to disinfect water and perform other tasks. New technology like solar ponds and solar chemicals are also being developed to provide power in much the same way as photovoltaics.
