Solar Panels – What is Solar Energy and How is it Generated?
According to the Department of Energy, an American family spends an average of $1,400 a year on lighting/heat. And that price is only increasing. The cost of energy has become so ridiculous that the alternative sources are beginning to compete with oil and coal for the first time since the 1970s. Wind, hydro, and geothermal power are examples of alternative energy, but the most popular option is solar energy.
Each day, the sun gives off around 1,000 watts of energy per square meter. It is the number one source of natural light and heat; nearly all living organisms rely on it to provide life, yet it’s still taken us a long time to consider it as a prominent source of energy. When the sun’s rays are converted into usable energy we could light/heat all of our businesses and houses for the cost of the equipment.
But what is solar power exactly? Many of us know that it comes from the sun, but how can we translate that into powering our appliances?
We utilize solar energy with the help of solar cells. Remember using solar powered calculators in school? Those calculators had a small solar panel, usually above the display screen, which was responsible for powering the machine without the help of batteries. Basically, the solar cells used for these calculators are called photovoltaic (PV) cells, which convert sunlight into electricity. Photovoltaic cells are made from semiconductor-material (silicon) which absorb sunlight and transfer it to the actual semiconductors. Once there, electrons are broken off and allowed to move freely. The cells then move the loose electrons into a certain direction to create a current – placing metal on the top and bottom of this stream allows practical use of the current in our homes, calculators, and wherever else is plugged in to accept energy from the panels. Panels used for private homes and businesses work using the same process, only on a much larger scale. This is a very simple explanation – there is a lot more to the process – but it’s useful to know the basic mechanics.
Besides saving money, there are numerous other benefits to installing cells in your home. Solar energy is environmentally responsible; by not supporting coal/fossil/kerosene-burning energies, we contribute to improving the air-quality. Power plants are major polluters and one of the major causes for diminishing our ozone layer. Generating solar energy also reduces the amount of greenhouse gases in the atmosphere. Carbon dioxide is the leading cause of global warming and massive amounts of it are released into the air every time from power plants that generate and distribute conventional electricity.
Collecting and generating energy from the sun also reduces the risk of fires. Every type of generator, lamp, or diesel fuel has the potential of failing, which could prove fatal and destructive. Energy from the sun doesn’t involve any such risks.
Solar panels are the safe, money-efficient energy option for the forward-thinking consumer.
