10 Maiores Usinas Solares do Mundo

10 World´s Largest Solar Power Plants

10. Central Solar Photovoltaic Moura, Amareleja, Portugal

Central Solar Fotovoltaica de Moura, Amareleja, Portugal
Technology: Solar Photovoltaic
Capacity: 46 MW

Although currently occupies the tenth place on the list, the central Moura is expected to go up position at the end of 2010, when another unit with a capacity of 20 MW of generation were to add up to 2,520 giant solar panels that exist today. The movable panels maintain a constant angle of 45 degrees. Most of them are set to fixed structures, but a quarter panels moves 240 degrees to follow the path of the sun each day. The plant already produces enough electricity for the annual electricity consumption of 15,000 Europeans, according to Acconia company that owns the plant and also installed a solar panel factory nearby.

9. Puertollano Photovoltaic Park, Castile, Spain

Technology: Solar Photovoltaic
Capacity: 48 MW

The solar power plant in Puertollano uses 231,653 fixed solar photovoltaic panels to generate electricity. Each panel is positioned at an angle of 33 degrees and facing south to maximize the generation capacity in the region, which is one of the sunniest in Europe. 


8. Alvarado I, Extremadura, Spain

Technology: Concentrating Solar Power (CSP)
Capacity: 50 MW

Completed in July 2009, the central Alvarado I uses parabolic trough technology and consists of 768 thermo collectors that supply electricity to power around 50,000 homes. The plant produces approximately 105,200 megawatt-hours of electricity per year (an average capacity of 12 MW). It is planned to build a second unit of 50 MW, Alvarado II, in the same area.

7. Andasol, Andalusia, Spain

Technology: Concentrating Solar Power (CSP)
Capacity: 50 MW

Andasol thermo power plant is the first parabolic trough, providing electricity for up to 200,000 people since March 2009. It is also the first commercial plant in the world of solar power with storage capacity. During the day, sunlight reflected by the parabolic mirrors heats molten salt. At night, the salt cools and releases heat, which generates more steam. This process allows the plant to generate 7.5 hours during the night or cloudy.

6. Lieberose Photovoltaic Park, Brandenburg, Germany

Technology: Solar Photovoltaic
Capacity: 53 MW

Built in 2009 on the site of a former military training area, the solar farm Lieberose is the second largest in Germany, occupying over 163 hectares. Actually, this is a temporary installation. The companies responsible, Juwi and First Solar, have a 20-year contract - after this deadline, the installation will be dismantled and the solar panels will be recycled. Lieberose uses thin-film solar panels and can supply up to 15,000 homes. The energy production of the park eliminates 35,000 tons of CO2 per year, equivalent to taking 8,500 cars from the streets.

5. Solar Park Strasskirchen, Strasskirchen, Germany

Technology: Solar Photovoltaic
Capacity: 54 MW

Inaugurated in 2009, this center belongs to a new generation of solar photovoltaic power plants of large scale that have proliferated in Germany since 2008. At the time, eight of the ten largest photovoltaic power plants in the world were in Spain, but in April 2010, Germany went on to lead the ranking. The plant has Strasskirchen generating capacity enough to supply 15,000 homes. Your park has about 25 000 solar modules using crystalline solar cell technology and are scattered in an area equivalent to 270 football fields. Reduces its production by 35 tons per year emissions of carbon dioxide.

4. Photovoltaic Park in Olmedilla, La Mancha, Spain

Technology: Solar Photovoltaic
Capacity: 60 MW

Completed in 2008, Olmedilla is the largest photovoltaic plant in the world, using 270,000 photovoltaic panels that convert sunlight directly into electricity, provided to 40 thousand homes. The plant was constructed in just 16 months at a cost of 384 million euros. Spain is a world leader in independent photovoltaic solar plants of large size, as the central Olmedilla, whose generation capacity exceeded 2800 MW in 2009. The generating plants dominate the Spanish solar market, having supplied about 80% of total solar capacity in 2008.

3. Nevada Solar One, Nevada, United States
Nevada Solar One, Nevada, Estados Unidos
Technology: Concentrating Solar Power (CSP)
Capacity: 64 MW

The generation plant Nevada Solar One uses solar energy to supply more than 14 million homes each year. For this, they are used more than 180,000 parabolic mirrors that concentrate sunlight on steel tubes filled with oil. The oil goes through a heat extractor that boils water and produces steam that drives electricity-generating turbine. The company Acciona, which owns the project, says that in terms of carbon emissions, this plant is equivalent to withdrawing from the streets of 20 thousand vehicles per year.

2. Martin Next Generation Solar Energy Center, Florida, USA

Technology: Concentrating Solar Power (CSP)
Capacity: 75 MW
A truck-crane hybrid and an electric car to connect to the network are displayed at the opening ceremony of the plant. Expected to be ready by the end of 2010, this facility will be the first plant hybrid thermo-powered and natural gas and must meet the 11 000 households per year. For the next 30 years or more, this plant will prevent the emission of more than 2.75 million tons of greenhouse gases. According to the EPA, the American agency of environmental protection, this is equivalent to taking more circulation of 18,700 cars each year over the next 30 years.

1. Generators Solar Energy Systems (SEGS - English, Solar Energy Generating Systems), California, USA
Technology: Concentrating Solar Power
Capacity: 354 MW

Consists of nine solar power plants - the two largest with a capacity of 80 MW each - the SEGS uses nearly one million parabolic mirrors to track the sun. The system concentrates the sunlight onto a central container containing synthetic oil, which is heated to 400 degrees Celsius. A heat exchanger transfers it to water which boils, and produces steam which drives the turbine. The company NextEra Energy Resources, which operates the power plant, says that SEGS powers 232,500 homes and stops emitting 3,800 tons of pollution from fossil fuels each year.
