Energy Facts

  • On a bright sunny day, the sun shines approximately 1,000 watts of energy per square meter onto the Earth’s surface.
  • PV cells produce no air pollution, hazardous waste, or noise, require almost no maintenance, and last for about 30 years.
  • Solar hot water systems are less expensive and pay for themselves more quickly than solar systems for electricity – typically in 5-10 years.
