Here is a collection of fascinating fun facts of solar energy. People have used the sun as a heat source for thousands of years. Only with advances in technology that have occurred in recent years have allowed us to fully exploit this power.
- Families in ancient Greece built their homes to maximize sunlight during the cold winter months. The ancient Greeks believed that the sun was the god Helios and led his car around the earth to the sky in the morning and evening back again.
- The discovery of the photovoltaic effect is credited to the physical Frenchman Alexandre-Edmond Becquerel in 1839.
- In 1921 the Nobel Peace Prize was awarded to Albert Einstein for the experiments with solar energy and photovoltaic.
- Back in 1955 the American Solar Energy Society held its first meeting in Phoenix and attracted the first Russian scientist to the U.S. after the Second War World. Lots of film showing early PV has been developed for NASA, solar cookers and solar heating panels.
- The first solar flight occurred in 1974 in California by an unmanned aircraft that was developed by two brothers Roland and Bob Boucher.
- In 1975, the ship was built solar the first in England and in 1996 Kenichi Horie of Japan made the first crossing of the solar power of the Pacific in a catamaran.
- The first World Solar Challenge took place in 1987. This is a solar car race which covers 3021 km through the interior of Australia from Darwin to Adelaide.
- Did you know that it is possible to drive any solar panel output by 75% simply by placing a mirror that is about twice the size of the group on the ground in front of the panel?
- PV cells do not need direct sunlight to work – you can still generate some power on a cloudy day.
- Solar electricity is a green energy, renewable and does not release carbon dioxide and other harmful pollutants. A typical household photovoltaic system could save about of 1200kg of CO2 per year, which is about 30 tons over a lifetime.
- You can store the electricity that their solar energy system generates batteries a cloudy day.
- You can sell any extra electricity produced using solar energy to the network and make some money.
- Only it takes about 8 minutes for solar energy to travel from the sun to the earth.
- Approximately 30% of the radiation we receive from the sun in the upper atmosphere is reflected back into space. The rest is absorbed by clouds, oceans and land masses on Earth. However, even under these conditions, the energy it receives our planet from just hours of exposure to sunlight is equal to the amount of energy that humans use in an entire year.
Large scale projects solar energy that are developing around the world show that the sun power of clean energy technology are achievable and profitable. The solar plants produce megawatts (MW) MW enough to power 1,000 homes. One of the largest solar energy projects that the world has ever seen is "Desertec" will use the North African desert uninhabitable for a mains power plants concentrated that could supply Europe with all its energy needs 2050. Both the progress is a very short period of time we will see where we go from here.
