Letting Sun Power into Your Water and House
Let the Sun Shine
Solar energy is a great resource that scientists have long explored as a means of providing energy to meet human needs. Thanks to advances in technology, there are now prototypes of various machines that run on solar power. These include solar powered cars, solar-heated homes, and solar-powered water heaters. In fact, many of these machines have gone beyond the prototype stage and are being used in many green homes throughout the world, where their owners are determined to help save the environment by decreasing their reliance on fossil fuels.
There are many ways to harness the power of the sun to allow our turbines to run, our water to be heated, and our homes to be conditioned at just the right temperature. One such method is the use of the solar panel, which you can often glimpse as a black platform filled with shining grids that glisten in the sun. This array of thermal collectors is connected to an appliance that can run on solar power.
The ability of appliances to run on solar power rests in the power of the individual grids on a solar panel. Each grid, called a photovoltaic cell or photovoltaic module, is arranged in a strategic array that is meant to collect the most sunlight and use the consequent energy most efficiently. Such photovoltaic arrays are in wide use nowadays, and have enjoyed an upsurge in production as their manufacturing costs have since diminished.
Photovoltaic cells use semiconductors to utilize sunlight and turn it into electricity. You can see such cells in your solar-powered calculator, emergency telephones on the roadside, and even in some large industrial complexes. With the lower cost of maintaining and manufacturing solar panels, you can use solar energy to heat your water and provide insulation for your home.
