Interesting fun facts about solar energy

In this article, we discuss some most important facts about Solar Energy and, How solar energy affects our day-to-day life.

Fun facts about Solar energy

  • 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.
  • It is possible to classify solar technology into active and passive. Solar thermal collectors and photovoltaic panels that employ solar energy fall under active solar technology, while constructing rooms to enhance air circulation and orienting space to properly use sunlight fall under passive solar technology.
  • Around 173,000 terawatts of solar energy continuously hit the Earth which makes this form of energy the most plentiful source of energy on the planet. The amount of energy that strikes the planet is over 10,000 times the total energy used in the world.
  • 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 lead to rains that again bring water to the surface of the earth and complete the water cycle.
  • Green plants use photosynthesis to convert solar energy into chemical energy that builds the biomass which composes the fossil fuels.
  • Solar energy is used by solar-powered hot water systems to heat water. Some areas allow for almost 60 to 70% water used locally for up to 60-degree Celsius temperatures to be provided by solar heating.
  • Solar energy was first used by Greeks and Romans in their designs. Their homes used to have south-facing windows, which let the sun heat and light their indoor spaces. Greeks, Romans, Native Americans, Greeks, Romans, and pueblo people used the sun to warm their homes in one or the other way.
  • 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.
  • 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.
  • Space missions by various countries use solar energy to power their spacecraft. Thermal storage systems can store solar energy in the form of heat by using common materials with high specific heat such as stone, earth, and water. Solar energy can also be stored in molten salts.
  • Developments in scientific researches are paving way for solar energy to be more reasonable down the road, with the costs reducing and efficiency increasing.
  • Horticulture and agriculture want to make maximum use of solar energy. These include techniques such as cycle time and mixing of plant varieties. Greenhouses are also used to convert light into heat to promote year-round cultivation of special crops.
  • The biggest solar power plant in the world is located in the Mojave Desert in California, covering 1000 acres.
  • Solar energy has been in use for 2700 years. In 700 BC, glass lenses were used to make fire by magnifying the sun’s rays.
  • The sun is also the main source of non-renewable fossil fuels (coal, gas, and petroleum), which began life as plants and animals millions of years ago.
  • The solar energy process replaces fossil fuels as a source of chemical energy and can make solar energy strong and transportable. Photosynthesis can create a variety of fuels. Technology for producing Hydrogen is a major area of solar chemical research.
  • Clothes can be dried in the sun using clotheslines, cloth racks, etc.
  • Food can be cooked, dried, or pasteurized using solar energy.
  • 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.
Solar Energy

Solar energy helps transform solar energy into various other forms such as electrical energy to fulfill global demands. At present, around 10% of global energy requirements are providing by solar energy, with the future potential being really strong.


Why is solar energy important?

Solar energy – a clean source, No greenhouse gas emissions are released into the atmosphere when you use solar panels to create electricity. And because the sun provides more energy than we’ll ever need, electricity from solar power is a very important energy source in the move to clean energy production.

Who invented solar energy?

In 1839, French physicist Edmond Becquerel discovered the photovoltaic effect while experimenting with a cell made of metal electrodes in a conducting solution. He noted that the cell produced more electricity when it was exposed to light.

Is solar energy the future?

In 2018, solar generated about 1.5% of US electricity. Of all renewable energy generation, solar PV is expected to grow the fastest from now to 2050. Some solar-heavy grids, such as the California Independent System Operator have experienced times where over half of the demand was met by solar PV.

What is new in solar technology?

The Shockley-Queisser limit marks the maximum efficiency for a solar cell made from just one material, and for silicon, this is about 30%. However, combining six different materials into what is called a multi-junction cell has been demonstrated to push efficiency as high as 47%, under concentrated light.

Do solar panels work in winter?

The short answer is, yes, they do! The longer answer of course is, yes solar panels work in winter weather, but for obvious reasons, their output is lower than during the height of summer days are shorter and snow can temporarily reduce or shut down the output.
