What is An Interesting Fun Fact About Solar Energy?

Solar energy has been used for more than 2,700 years for heating, cooking, and other essential applications that make our lives more efficient. It’s obvious why the sun has been such an essential resource for humanity if its rays can heat our bodies while we’re just walking around outside, there must be other things we can do with it!

Yet, solar energy technology really only came into its own in 1954, when Bell Laboratories created the first commercially viable solar cell. Since then, solar power has leaped into prominence as the fastest-growing sector of the energy economy, creating jobs at six times the rate of the general job market. There are just so many advantages to using solar energy whenever and however possible.

Fun facts about Solar energy

  1. Solar energy has been used for over 2700 years. In 700 BC, glass lenses were used to make fire by magnifying the sun’s rays.
  2. 174,000 terawatts of energy consistently strike the earth as solar radiation at any moment, even on the cloudiest of days.
  3. The Greeks and Romans were the first to use passive solar designs. Buildings with south-facing windows allowed the sun to heat and light indoor spaces.
  4. In 1447, Leonardo Da Vinci predicted there would be industrial solar use. Using solar power to heat water.
  5. The first silicon solar cell, the precursor of all solar-powered devices, was built by Bell Labs in 1954.
  6. In the 1960s the space industry began to use solar technology to provide power aboard spacecraft. The Vanguard 1, the first artificial earth satellite powered by solar cells, remains the oldest manmade satellite in orbit, logging more than 6 billion miles.
  7. Photovoltaic cells were next widely used for small consumer electronics like calculators and watches. Many road and traffic signs also are now powered by PV. In most cases, PV power is the least expensive form of electricity for these tasks.
  8. The largest solar power plant is located in the Mojave Desert in California. The solar plant generates 90 percent of the world’s commercially produced solar power!
  9. More energy hits the earth from the sun in one hour than the whole world uses all year. If you’re a numbers person approximately 120,000 terawatts (TW) hit the earth’s surface each day. Over the course of a year, the world uses a mere 15 TW of energy.
  10. Estimates say that one square foot of solar panel gives an output of approximately 10 watts of power.
  11. Solar Energy is measured by the kilowatt hour. One kilowatt = 1000 watts.
  12. Solar energy produces no pollution when generating electricity. Using solar energy produces no air or water pollution and no greenhouse gases.
  13. Solar power is noise pollution-free. It has no moving parts and does not require any additional fuel, other than sunlight, to produce power.
  14. One kilowatt-hour (kWh) of energy will burn a 100-watt light bulb for 10 hours.
  15. Solar energy is a very reliable source of energy. The sun shines every day without fail.
  16. When located on buildings, solar energy systems have minimal impact on the environment.
  17. It’s no secret that solar energy is the way to a more sustainable future. Solar panels can produce a 1-kilowatt (KW) solar energy unit to replace the equivalent of burning 170 pounds of coal and 300 pounds of carbon dioxide.
  18. Germany is known to be the leader in solar panel installations. The others on the top are Italy, Japan, and the USA.
  19. Solar energy is a 100% free energy source and is available in cornucopia. The sun is definitely 90 long million miles away from the earth, but it still only takes not even 10 complete minutes for sunlight to travel to earth.
  20. Solar insulation leads to the water cycle which is really important. It is due to solar radiation absorption by the earth, atmosphere, and oceans that their temperature increases. Warm air elevates from oceans which leads to convection. When the air reaches up, condensation of water vapor creates clouds which leads to rains that again bring water to the surface of the earth and complete the water cycle.
  21. Green plants use photosynthesis to convert solar energy into chemical energy that builds the biomass which composes the fossil fuels.
  22. Solar energy can help make brackish, potable, or saline water. It allows for dealing with wastewater without any use of chemicals or electricity. Further, the energy is also used to create salt from seawater for years.
  23. Solar panels are virtually maintenance-free as the battery does not require water or other regular service and will last for years. Once solar panels are installed, there are no recurring costs.
  24. Clothes can be dried in the sun using clotheslines, cloth racks, etc.
  25. Food can be cooked, dried, or pasteurized using solar energy.
  26. Solar chimneys are passive solar ventilation systems. Shafts connect the interior and exterior of the building. The functioning can be improved by glazing and using thermal mass materials.
  27. Solar energy is the cheapest source of energy in the world as of 2017.
  28. Solar energy is cheaper than fossil fuels as of 2019.
  29. China is the world leader in solar energy generation.

A.E. Becquerel

Where did modern solar power get started? The roots of modern solar power can be traced back to 1839. It was at this time that a 19-year-old French physicist, A.E. Becquerel, whose focus up to that point had been related to phosphorescence and luminescence, discovered the photovoltaic effect.

What is solar energy used for?

The most commonly used solar technologies for homes and businesses are solar photovoltaics for electricity, passive solar design for space heating and cooling, and solar water heating. Businesses and industries use solar technologies to diversify their energy sources, improve efficiency, and save money.

What do solar energy do?

Solar technologies convert sunlight into electrical energy either through photovoltaic (PV) panels or through mirrors that concentrate solar radiation. This energy can be used to generate electricity or be stored in batteries or thermal storage.

How long can solar panels last?

About 25 to 30 years

But the solar panels generating that power don’t last forever. The industry-standard life span is about 25 to 30 years, and that means that some panels installed at the early end of the current boom aren’t long from being retired.

Where does solar energy come from?

The photons that reach your solar cells and generate an electric current come from somewhere – the sun. Solar energy is created by the constant nuclear fusion reactions occurring deep within the sun.

Who invented solar glass?

Invented by 27-year-old engineering student Carvey Ehren Maigue, from Mapua University in Manila, the solar windows can convert the Sun’s ultra-violet light into electricity.

How Many Solar Panels Would It Take to Power the World?

It would take 51.4 billion 350W solar panels to power the world! Put another way, this is the equivalent of a solar power plant that covers 115,625 square miles.

How efficient is solar energy?

Most figures say that solar panels are roughly between 15% and 18% efficient, meaning that 15% to 18% of the sunlight they absorb is converted into electricity while the rest hits the solar panel and warms the surface like it would anything else.
