Solar Cells

This is where solar energy begins - the solar cell

Whether or not you knew it at the time, you have more than likely seen a solar cell at least once in your lifetime. Solar cells have been around for a number of years and have been used to power a number of different appliances and devices. The term has been more and more popular in recent years as more and more people are trying to protect the environment while saving money by going green. So what exactly are solar cells? What can they do for you? And why have they become so increasingly popular in the last couple of years? After reading this article you should be able to answer all of the questions above while understanding the benefits of solar cells.

Solar Cells - solar energyOk, I heard the term solar cell so what is it? Well, a solar cell, also known as a photovoltaic cell, is a device that is capable of transforming solar energy into electricity.

This is done using the photovoltaic effect. Simply put a solar cell is a device which is used to capture energy from the sun while a photovoltaic cell is a device that captures energy from an unknown source. To power large appliances it is possible to combine or assemble together a large number of solar cells. A group of solar cells assembled together is usually referred to as solar modules which are linked to photovoltaic arrays.

Solar cells have been used for many years to power small appliances and devices. The most commonly thought of solar powered device of the device has to be small calculators. These are the types of calculators that required no batteries at all and were functional anytime they happened to be reaching sunlight. This is possible because they were embedded with solar cells on the front which transformed the sunlight into electricity and in turn powering the calculator. The small solar cells were able to deliver sufficient energy required by the calculator to power the calculator at all times. Some of these calculators weren’t even equipped with an on and off button.

Of course, other devices of the past were capable of running off solar energy as well including sun lights. These are the lights that are placed in your yard or garden. They generally gather energy throughout the day using the sun and a group of solar cells equipped on top of the light itself. Most of these lights normally don’t come on until it begins getting dark outside. If it was sunny enough on that particular day then the light should have stored enough energy to be able to operate all throughout the night without going dim. If the light happens to go dim then either something is wrong with the solar cells or they just didn’t receive enough sunlight during the day.

As technology has advanced throughout the years, solar cells have become more and more high tech. They are now capable of heating the water using in your home or swimming pool and even powering any device or appliance in your home that runs off of electricity. Unlike fossil fuels, using solar power doesn’t emit any harmful pollutants or greenhouse gases into the atmosphere. Solar energy is also less expensive than conventional electricity. Since sunlight is completely free or charge you will never have to pay another electric bill. Of course, the initial cost of a solar energy system is expensive but you will end up making your money back and saving more down the road.
