The World's First Solar Power Station


It lives by night: The Gemasolar solar power station near Seville has an incredible 2,650 panels spread across 185 hectares of rural land

It looks like a giant art project. But this symmetrical, circular pattern of mirrored panels is the world's first solar power station that generates electricity at night. The Gemasolar Power Plant near Seville in southern Spain consists of an incredible 2,650 panels spread across 185 hectares of rural land. The mirrors - known as heliostats - focus 95 per cent of the sun's radiation onto a giant receiver at the centre of the plant.


The power station was completed last month. Its mirrors - known as heliostats - focus 95 per cent of the sun's radiation onto a giant receiver at the centre of the plant. The heat stored can be released for up to 15 hours overnight, or during periods without sunlight



Heat of up to 900C is used to warm molten salt tanks, which create steam to power the £260million station's turbines
