Sun Facts


  • Michigan's climate creates more voltage per sunlight hour than hotter climates like Southern California, Arizona and Florida because solar panels perform better in colder temperatures.
  • The Earth receives 122 petawatts (122 with 15 zeros after it) of incoming solar radiation from the sun, at any given point in time
  • On a clear day the energy that hits 1 square meter of earth equals 1000 watts of energy.
  • The energy that hits the earth from 1 hour of sunshine could power the planet for a year.
  • Silicon cells, the major component of solar panels, manufactured from 1 ton of sand can produce as much electricity as burning 500,000 tons of coal.
  • The sun is approximately 90 million miles from the Earth.  It takes energy waves 8 minutes and 19 seconds to travel from the sun to the Earth.
  • The International Space Station is completely powered with solar energy.  The space program started using solar panels in 1958.
  • Solar panels first came onto the market in 1956
  • Solar energy has been used for over 2700 years:  In 700 B.C., glass lenses were used to make fire
  • As of 2017, China is the world leader in renewable energy, the US comes in second and Germany is third
  • In 1447, Leonardo Da Vinci predicted there would be a solar industrialization
  • The cost of solar is the inverse of the cost of oil:  The more panels that are produced, the less they will cost;  The more oil consumed, the more it will cost.
  • As of 2017, three OPEC members, with no incentives for energy production, requested proposals for the cheapest form of energy generation.  In each case, solar won!  These countries included Dubai, Saudi Arabia and Mexico.
  • On a yearly average, Michigan has approximately 4.1 hours of peak sunlight per day.  In contrast, Arizona averages 6.6 hours of peak sunlight per day.  One hour of peak sunlight delivers 1,000 Watts of power, per square meter.
