The rapid consumption of non-renewable sources like coal, gas, and oil is increasing its pace at an alarming rate. To prepare for the future and shift to a sustainable source of energy, many countries have started to use solar energy extensively.
The sun has been the most important source of energy for life forms for billions of years. Nowadays, solar power technologies use the sun to heat homes, produce hot water, and light homes. One of the perks of using solar energy is that it’s a clean source of energy that does not produce pollutants. Its only limitation is that is the amount of sunlight received depends on the time of year, time of day, location, and weather conditions.
Here are ten facts on solar energy that you may need to know:
Solar energy is limitless, and it is entirely free. The solar panels that used for producing power are designed to capture wavelengths of the sun’s radiation and convert them to electricity. This is the most abundant energy on Earth. At every moment as much as 173,000 terawatts of solar energy continuously strikes the Earth. That represents more than 10,000 times the total energy used currently in the world.
The demand for solar energy in the US today is at an all-time high. At this point in our country, we’re set to become the world’s fourth largest solar market.
Solar energy does not emit so much greenhouse gas emissions as fossil fuels. Renewable energy has a substantially lower environmental impact over the lifespan the power source.
It is important to expand solar power production to be able to meet climate goals and limit global warming back to the pre-industrial level. In this context, Technicians are forecasting that by the year 2050 solar power energy will provide over 10 percent of global electricity.
Photovoltaic cells that compose the solar panels cause a reaction on an atomic scale between electrons and photons. The electrons get catapulted loose when photons collide with electrons. Then, these free electrons can be captured and used as electricity.
Photovoltaic cells are usually made from various types of silicon.
Sunlight takes slightly more than eight minutes to reach Earth and just a few seconds longer to reach your solar panels.
To capture optimal sunlight, solar panels in the US need to face south.
Solar power is measured in watts, like all electricity.
Your solar panel system can use a special battery as a backup when the sun isn’t shining. Most modern solar units, however, use net metering.
