6 FAQs about [Mirror array solar energy]

How can we generate electricity without a mirror array?

MIT researchers find a way to generate power without the usual mirror arrays. Most technologies for harnessing the sun’s energy capture the light itself, which is turned into electricity using photovoltaic materials.

Why are electric utility companies using mirrors?

Electric utility companies are using mirrors to concentrate heat from the sun to produce environmentally friendly electricity for cities, especially in the southwestern United States. The southwestern United States is focus-ing on concentrating solar energy because it's one of the world's best areas for sun-light.

How does a solar receiver work?

The receiver collects the sun's heat in a heat-transfer fluid (molten salt) that flows through the receiver. The salt's heat energy is then used to make steam to generate electricity in a conventional steam generator, located at the foot of the tower.

How does a solar power tower work?

A solar power tower consists of an array of dual-axis tracking reflectors (heliostats) that concentrate sunlight on a central receiver atop a tower; the receiver contains a heat-transfer fluid, which can consist of water-steam or molten salt. Optically a solar power tower is the same as a circular Fresnel reflector.

How do heliostat mirrors work?

Fields of heliostat mirrors focus sunlight on receivers located on centralized solar power towers. The receivers generate steam to drive specially adapted steam turbines. For the first plant, the largest-ever fully solar-powered steam turbine generator set was ordered, with a 123 MW Siemens SST-900 single-casing reheat turbine.
