You hear a lot about solar energy in detail, various solar systems such as solar system for residential purposes, solar system for business and various other utilization ways. Today, you can find out some cool facts about solar energy!


  • Solar energy’s source is absolutely free and the source Sun is 90 millions miles away and yet the sunlight reaches the earth within 10 minutes!
  • 174,000 terawatts of energy strikes our planet earth even on cloudy days.
  • Solar panels costs have fallen by 99% since 1977
  • Solar energy is cheaper than fossil fuel energy
  • Solar panel systems can last from 50 years to a whole lifetime!
  • As of March, 2021, 2.77 million solar systems have been installed in Australia!
  • Solar panels are used in spacecrafts and satellites
  • First ever silicone solar cell was created in Bell Labs in 1954.
  • Space industry was the first one to utilise solar rather than the earth industries!
  • Solar energy production is absolutely air pollution, noise pollution and earth pollution free.
  • World largest solar power plant is spread over 1000 acres, in Mojave Desert of California, USA
  • As of 2017, the sun is the cheapest source of energy.
  • China leads the world in solar energy production.
  • Solar energy users can save about 35 tons of carbon dioxide and 75 million barrels of oil every year.
  • Photovoltaic effect that is used in the solar power systems was first discovered in 1839 by Alexandre Becquerel.
  • Hundreds of years ago, Greeks and Romans used the sunlight’s solar energy to light the sacred torches by focusing the solar rays with the use of mirrors.
  • In 1941 Russell Ohl created the first photovoltaic cell.
  • Solar panels don’t need direct sunlight to produce solar energy.
  • Solar panels can produce solar energy even on cloudy days.
  • Solar systems are used efficiently even in the regions where snow is heavy and frequent.
  • There are multiple types of solar panels such as monocrystalline, polycrystalline, thin-film etc. The most efficient solar panels are the monocrystalline ones.
  • Einstein made significant contributions to the field of solar energy. Einstein wrote a paper on the topic and that helped bring the attention of global masses onto solar energy. He also proved that it is a viable energy production system and energy source.
  • The oil crisis of 1970 made the world realise that the world can no longer rely on fossil fuels only, an alternative is a must.
  • Most common use of Solar energy is household appliances usage and industrial usage through solar panels.
  • Solar energy is also utilised for various purposes such as street lights and signals operating.
  • Solar energy can be used to charge your mobiles, the solar energy utilising mobile chargers were launched a few years ago.
  • Calculators can also be powered by solar energy. Calculators have a stripe of panel like surface which directly gets charged and runs the calculator, you don’t need a separate mechanism or device.
  • Solar power can significantly reduce your electricity bills, you can even have an off-grid high capacity solar system and be absolutely independent.
  • Jimmy Carter, the former president of the USA, had solar panels installed on white house in order to spread awareness about solar energy and encourage people to opt for solar energy through solar panel systems.
