Só por curiosidade, quanto é custa o kwh da electricidade produzida por esta central?

tarifa 0.31 / 4x superior a eólica e 8x superior a hídrica



estado pagou 3,5 milhões a fundo perdido (subsidio EU - PRIME)

estado paga 75 milhões aos "privados" nos próximos 15 anos, (os privado investiram 61 milhões)

os 52 mil painéis foram importados da China

vai empregar 5 pessoas



a tecnologia ainda não está madura, é um erro investir assim à grande


basicamente isto serve apenas como arma politica, como propaganda para o governo



o ferrol é que percebeu bem a noticia


Agora me explico porque se vai instalar unha fábrica de panéis fotovoltaicos en Ourense. É bó negocio  :shock:

Portugal opens major solar plant
 
The solar power plant is in one of Europe's sunniest areas

Portugal has inaugurated what it says is the world's most powerful solar power plant.

The array of electricity-generating solar panels covers about 60 hectares (150 acres) in one of Europe's sunniest areas in southern Portugal.

Officials say the plant should produce enough energy to supply 8,000 homes.

The plant is part of Portugal's efforts to cut its reliance on imported fuel and reduce emissions of greenhouse gases that add to global warming.

The plant is also meant to bring development and jobs to the Alentejo region 200km (125 miles) southeast of Lisbon, a poor area traditionally dominated by cork and olive production.

Renewable energy drive

The 11-megawatt plant has 52,000 photovoltaic modules, which will produce 20 gigawatt hours of power each year.

Burning fossil fuels to generate the same amount of energy would result in 30,000 tons of greenhouse gases being emitted over the course of a year.

"This project is successful because Portugal's sunshine is plentiful, the solar power technology is proven [and] government policies are supportive," said Kevin Walsh of Renewable Energy GE, which built the project.

The facility was designed by PowerLight which will also operates and maintains it.

Portugal is developing wind, solar and wave power projects as part of a plan to invest $10bn (£5bn) in renewable energy over the next five years.

Prime Minister Jose Socrates has said he wants 45% of Portugal's power consumption to come from renewable energy by 2010.

Com a rentabilidade dos painéis solares de momento nos 12-15% a energia solar pode não parecer muito eficaz, mas os painéis de nova geração prometem valores de até 80 %, o que é, digamos, bastante interessante. O desafio está em produzi-los em massa (baratos).
I hope that you accept Nature as It is - absurd.
