Since climate change is discussed more and more, to enjoy the greatest popularity of alternative energy sources! It is proved that the earth’s resources will be exhausted 2050! Global warming is an issue that affects all people worldwide. This inevitably means that we are in a different direction must be based. Apart from wind and hydro energy, solar technology is also very popular. Some businesses here are leading by example and then draw their energy from alternative energy sources. Among other things, these can equip their buildings with solar panels. At the Solar Power These are a method which makes use of the energy of the sun. Solar cells are used to heat water, which is then stored in a large, well-insulated tank. Solar technology also finds application in the field of electricity generation. Thanks to new innovations the new-generation solar cells in a position even in the winter to generate electricity or heat water. In the areas around the equator, solar power plants are apopular alternative to the traditional oil power stations. The widespread opinion that solar cells (only on a large scale that is in the order of a power plant) are efficient and are therefore not suitable for households, is simply wrong! Just a few square meters are sufficient to significantly reduce the water or electricity to a household, if not covered. Particularly useful is mounting on large surfaces, such as on barns and schools. In some cases, it even happens that these cells produce as much electricity that the owner can sell power back to the neighbor and therefore does not have an additional source of income.
