History of Photovoltaic solar panels
The first cells had 4% efficiency and were produced in 1950. Today the third generation of photovoltaic panels cell contains a 20% efficiency and hope few years to grow.
Solar cells before were often used for personal computers and for watches. It is used supplying artificial satellites, space station, distant outposts.
In our days photovoltaic panels entered in most areas and social environments.
Price varies depending on the needs of electrical enclosure which is mounted system, it can provide between 20% and even 80% from necessary consumption, for certain periods of time.
EU settlements require member countries as a significant percent of the energy produced from these until 2012 be by alternative means.
Increasing the amount of solar energy converted into electricity of solar system panels may be increased in two ways: add more panels or increase efficiency photovoltaic cells. The second method preoccupy scientists which could establish a new record efficiency, 40,8 %, with 0.1% more than the previous record established two years ago.
In tropical areas it causes burning bushes, fire burst due focus sunlight through dewdrops that behave like optical lenses. The Greeks used solar energy from 400 B.C. for fire ignition using glass globes filled with water. In 200 B.C. they and the Chinese used concave mirrors for this purpose.
