Just ask a car driver in Arizona during the summer, when the temperature inside a parked vehicle can reach 150 degrees Fahrenheit. Solar energy may also be used to provide heat, which it does frequently. Solar collectors, which capture the heat and circulate it with water, are often used to provide heat to a house or for hot water. This is often used to heat swimming pools, allowing them to be used for longer periods of time during the year. look at this site
However, the sun’s influence is still used in a variety of less obvious ways, and you might have seen some of them. Photovoltaic technology, which generates electricity from the sun to light a home, has a wide variety of applications. Outside path lights with photovoltaic cells built into the top and a battery inside are available that do not need an electrical connection. When it gets dark, the lights turn on, using the solar energy stored in the battery to provide evening lighting in the backyard. The same concept is used for road signs in remote areas, which can be identified by the solar cells attached. A calculator with built-in solar cells, which normally supplements the battery power, is another usage that many people have.
The invention of solar cells that can complement or replace the power to your house is a major focus of research and design in solar energy today. These are large, maybe a couple of hundred square feet in size, and are usually mounted on the roof. They provide enough electrical energy for a well-run house to work normally. In 2005, a law was passed in the United States requiring energy providers to introduce net metering, in which excess electricity produced on site and pumped into the network is used to cover the cost of electricity supplied. As the power grid becomes the storage, this effectively replaces the previous need for batteries for energy storage, lowering the cost and inconvenience. Some states are still working on this rule, while others have adopted it wholeheartedly, and it’s set to change the way we think about solar energy in the future.
