Here is a collection of extraordinary solar power fun facts. People have used the sun as a heat resource for hundreds of years. It is only with the advancements in technology that have taken place in recent years that have enabled us to finally harness this energy.

Families in ancient Greece designed their homes to get the most sunlight during the cold winter months. The ancient Greeks thought that the sun was the god Helios and he drove his chariot round the earth up towards the sky in the morning and in the evening back again.

The discovery of the photovoltaic effect is credited to the French physicist Alexandre-Edmond Becquerel in 1839.

In 1921 the Nobel Peace Prize was given to Albert Einstein for investigations with solar power and photovoltaics.

Back in 1955 The American Solar Energy Society held its first meeting in Phoenix and attracted the first Russian scientist to the US since the second World War. There is film footage presenting early photovoltaics which was designed for NASA, solar cookers and solar heating panels.

The first solar flight took place in 1974 in California by an unmanned plane which was put together by two brothers Roland and Bob Boucher.

In 1975 the earliest solar vessel had been constructed in England and in 1996 Kenichi Horie from Japan made the first solar powered crossing of the Pacific Ocean using a catamaran.

The earliest World Solar Challenge was held in 1987. This is a solar-powered car competition covering 3021 km over the Australian outback from Darwin to Adelaide.

Did you know it is possible to boost any solar power panel productivity by 75% by simply placing a mirror that is approximately twice the size of the panel on the surface in front of the solar panel?

PV cells do not need direct sunshine to work - you may still produce some electricity on a cloudy day.

Solar electricity is an eco-friendly, sustainable energy that does not release any harmful carbon dioxide or other pollution. An average home Photovoltaic system could save about 1200kg of CO2 annually which is about 30 tonnes over a lifetime.

You can store the electrical energy that a solar power system produces in batteries for a cloudy day.

You can sell any excess electricity you generate using your solar power back to the grid making a little bit of money.

It takes no more than 8 minutes for solar energy to travel from the sun to the earth.

Approximately 30% of the radiation we receive from the sun at the upper atmosphere is actually reflected back up into space. The remainder is absorbed by the clouds, oceans and land masses on Earth. Nevertheless even in these types of conditions, the power that our planet gets from merely a single hour of sun exposure is equivalent to the amount of power that humans use within a whole year.

Large scale solar projects which are being developed world wide show that sun powered clean energy technologies are both attainable and also profitable. Solar power plants produce Megawatts (MW) with one MW being enough energy to supply 1000 households. One of the largest solar power projects which the world has ever seen is the "Desertec" program to utilize the uninhabitable North African desert for a power grid of concentrated thermal power stations that could supply Europe with just about all of its energy requirements by the year 2050. So much progress in such a short period of time let us all see exactly where solar electricity will go from here.

Solar Power Companies - Facts ÄÂt Is Advisable To Know About The Global Energy Leaders
These days there are thousands of solar power companies that are able to supply solar power equipment to homeowners who want to save money on their energy costs.

Photovoltaic Cell Gathering Being A Green Energy Supply
Photovoltaic cells are getting more efficient and gradually less expensive thanks to innovative designs which allow them to focus the gathered sunlight on a concentrated point.

Alternative Energy On The Pacific Ocean: Hot Sea Water Found On The Surface
Ocean Thermal Energy Conversion (OTEC) was conceived by the French engineer Jacques D'Arsonval in 1881. However, at the time of this writing the Natural Energy Laboratory from Hawaii was the home to the only operating experimental OTEC plant on the face of the earth.

Nikola Tesla Free Energy - From Solar Panels To Magnetic Motors; Free Environment Friendly Energy Is Available
Tesla free energy is not a new concept. Nikola Tesla invented free energy in the late 1800s. His inventions were so far advanced, that many his innovations were often overlooked.
