Solar power

Laundromat in California, produced energy, those in parts as (Radiation energy) to arrives. The solar power is approximately constant over hundreds of years. The intensity of the sun exposure amounts to at the border that about 1,367 KW/m²; this value becomes also as Solar constant designated. A part of the irradiated energy becomes from the components of the atmosphere absorbed and converted into warmth (kinetic energy). A further part escapes by those Emission a part of the absorbed energy toward universe of the earth and those leads last Reflection at suspended particles such as ice crystals and dust in air to a further decrease of the taken up energy. The size of these losses depends on the condition of the atmosphere. Those play Air humidity, those Cloudy appearance and the length of the way, which the jets must take by the atmosphere, a role. On those Earth's surface hitting radiation amounts to on perpendicularly to it a standing surface still approximately 1 kW/m². Surfaces set up for incident radiation diagonally hits less energy.

In 19. Century one accepted, the sun would consist of Coal and this would burn; however the sun on this assumption could only for approximately 6.000 years shine.

Use of the solar power

The use of the solar power furthest common on earth is those Photosynthesis with that Plants. All animals live directly (herbivores) or indirectly (carnivores) on the solar power.

Those Solar technology concerns itself with the use of the solar power. It becomes with the help of that Fotovoltaik in electricity (Solar electricity) converted or those Infrared oneRadiation becomes as Warmth in SolarthermiePlants caught and used. The transformation in warmth through so mentioned Solar collectors is the use of the solar power usually-spread world-wide. Of the direct transformation of the radiation in warmth avail themselves also Solar furnaces and Solar digester. Industrially the in such a way won warmth can in Solar heat power stations for the production of electricity to be used.

The solar power ranks among that regenerativ energies, their use is promoted in many countries, to Germany for example by that Renewable energy law (EEG).

Also those leave themselves actual Wind energy as well as the sources of energy Biomass and as forms of solar energy, since they use converted solar power by natural physical or biological processes.

Storage of the solar power

The solar irradiation is an unsteady size. Day and night, natural cloudy appearance as well as vapor trail, absorb and also suspended particle in air affect the local Irradiancy. In order to ensure necessary power supply security, therefore solar are with the enterprise Power stations always additional measures necessarily. The existing Electricity mains can serve for the reconciliation of local fluctuations. Power stations from other ranges of the regenerativ energies, for example Hydro-electric power plants, Wind energy plants or Geothermiekraftwerke can solar power stations supplement. In addition the parallel enterprise of conventional power stations is necessary, in order to adjust short term fluctuations even in the long run. A further possibility is those Energy storage, so that fluctuations from this memory to become balanced to be able. Different beginnings in addition are possible, with small plants as well as island plants become frequently Solar batteries begun. Here it concerns a chemical energy storage. Also storage in industrial chemical memory is possible, at present obtained Efficiencies for again the energy usable from it lie with approximately 50 per cent. Solarthermally produced warmth can preferentially in the summer in geothermal seasonal memory to be brought in and in the winter used. Another procedure is the transformation of metallic materials, for example that SolzincProcedure. A further possible procedure is the transformation of the electricity in Rotationsenergie (Flywheel), like it for example in the strassenbahndepot that Intalliance AG in Hanover-flax-live one realized.

Potenzial of the solar power

As the largest energy source the sun per year supplies an energy quantity of approximately 3.9 · 10²⁴
