Did you know that solar cells can provide so much energy that one solar cell can power a computer for several years? Solar cells can be very expensive, but can be very efficient. Solar cells are made of conductor metals that help convertheat into electricity. Once light hits the cells loose electrons get knocked out of the semiconductor metals. Conductors have to be attached to the positive and negative fuel rods to create an electric current. These solar panels could cost a range from $300-5000.
A solar cell is a device the turns precious light energy into electric energy. Using this way is a better way to make this earth cleaner. Instead of using pollution fuels you can have a cleaner way to make energy. Solar cells are being used more and more each day, for example some people have their houses powered by solar energy. Also there are solar powered calculators. Solar powered calculators work very efficiently and never die out as long as there is a enough amount of sunlight. Although large solar panels are less common than solar powered calculators they are everywhere if you have a good eye. Believe it or not but they take the same amount of energy in a year.
Solar cell products are very costly, but they are good if you like to save energy. This is because all the energy that solar cells
produce comes from the sun. It is also hard to make solar reflectors to produce solar energy into the battery. The hope for a solar revolution has been around for decades because it would cut down on the use of processed energy and the price of electricity bills. There are different types of solar reflector pads. The larger ones are called photovoltaics which were ounce only used in space. In space photovoltaics were used for powering satellite electrical systems.
You may wonder how is solar energy going to power all of America . Well the sun produces 1,000 watts of energy per square mile of each parts of earths surface . That's more than enough to power half the earth. Out of all, solar cells are a very productive way to use energy and they don't process energy they use the energy straight from the sun so there will be a big reduce on electrical power outs.
