Solar power plants
Alternative energies: the energy for the future?
Different kinds of solar plants
Parabolic disk with Stirling motor Photovoltaics cells
Plants with cylindrical concentrators CCP
Plants with tower receptor and heliostates
Different kinds of solar plants
The thermosolar plants produce electricity with the concentration of the heat in a point and producing steam than can be transformed in electricity by turbines or other motors.
This kind of plants produce electricity by photovoltaic cells that transform the heat of the sun directly in electric energy. This electricity goes to the national electric network.
Solar plant with cylindrical receptor
The solar grabber has cylindrical form and a reflecting surface where all the heat is concentrated in a pipe.For this pipe passes a fluid that heats and produce steam. This steam is transported to a turbine.This turbine produces electricity.
Photovoltaic solar plants
The main components are: -photovoltaic cells-Power room where it stocks the continuous current and it is transformed in alternating current (converters)-line of connection with national electric network
Photovoltaic solar plants
The photovoltaic solar panel is formed by cells of silicon and we can distinguish different parts:-Negative contact.-Special charge zone.-Positive contact.
The movement of the electrons between the different parts of the cells produces electricity.
Solar thermal plantThe panels reflects the solar light in the heliostats of the recollection tower, where there is a boiler. This boiler heats the water or the liquid of the pipes to produce steam.
This steam runs through a turbine which produce electricity that is connected with the electric network.
Solar thermal plantsThe steam is produced in the heater. In these solar plants, the plates are mirrors that send the heat in a tower with a boiler, where is produced the steam that runs turbines. These turbines produce electricity. The panels can be made by aluminium, plastic or glass.
Solar plant with Stirling engineThe components of these grabbers are:-Grabber with parabolic form, made by materials like aluminum or other metals to concentrate sunlight.-The receiver, between the grabber and the engine, it absorbs all sunlight and sends the heat to the engine. -The Stirling engine (invented in 1816) that transforms the heat in mechanic energy and can produce electricity.
Radiation hours in Europe
In this map we can see the radiation’s hours in Europe:This information is very useful to know in which zones can be more productive the installation of solar plants.We can see three big strips:-The south or the Mediterranean slope, with more hours of sun (yellow)-In the centre of Europe: Germany, Switzerland, etc, And the British islands. (green).-North of Europe: Nordic countries, etc. (blue)
Solar power installed in Europe
We can see the solar power installed in Europe in solar plants and domestic uses or public services.The countries with more solar power installed are:-Germany-Spain-Italy -France
Solar power installed in Europe
In these graphics we can see the main countries in Europe with solar power installed. The most important is Germany. Spain was the second until 2010. In 2011 and next years Italy installed more plants and now is the second.
Radiation in the world
The red are the zones with more radiation and the blue with few hours of radiation
Solar power in the world
In 2008 the 81 % of solar energy production in the world was installed in Europe.We can see, too, the ten solar plants with more production in the world in 2011.
The solar industry in the worldThe best zones in the world to find work in solar industry
The best zones in the world to install photovoltaics cells
The best zones in the world to create a solar entreprise
World situation of solar power energy
In this graphic we can see the increase of the solar power installed in the world. This increase Is more important between 2008 and 2010. It’s important the increase In China.
The modern installation in the world
The biggest solar tower in the world. Arizona (USA)
Comparative of the height of the tower
Sun-Moon Mansion in Dezhou, China
Radiation hours in SpainIn this map there are the average or radiation in Spain:
Zone V: South and the center the averages is 5 KWh/m2 or more
Zone III and IV: center and Mediterranean areas the average between 4,2 and 5 KWh/m2
Zone I and II: North and Cantabric coast the averages is 4,2 KWh/m2 or less
Photovoltaic power in SpainIn this map we see the photovoltaic power installed in Spain in 2004.
The main zones are:-Andalusia-Navarra-Catalunya-Castella i lleó
Thermosolar plants in SpainIn this map there are the biggest thermosolar plants in Spain. They are in Andalucía and Castella-La Manxa.
In the graphics there is the evolution of solar power installed in Spain. The increase is very important between 2008 and 2010.
Solar energy in Spain
In the graphics there is the installation of photovoltaic energy by region. The most important are in the South and the center (Andalusia, Extremadura, Castelles)
Solar plants in Spain
One of the ancient plants in Madrid (80’s)
Sanlucar la Mayor - Sevilla
Almería - Andalucía
Thermosolar plant of Sevilla – Sanlucar la Mayor
One of the modern plants in the world. It uses salt to keep the heat of the sunlight and it can work without sun 15 hours.
Photovoltaic power in the worldIn 2008 the leader countries of new installation of photovoltaic power in the world was Spain and Germany. And other European countries were in the list of top ten.
Radiation hours in CataloniaThe orange zones have more radiation, there are in the center and Mediterranean coast.The green zone, in the north, has fewer sun radiation.
There are 81 villages and cities in Catalonia that have rules to promote the use of solar energy.There are 12000 m2 of thermic captators.
