Solar Power

Solar thermal is a branch of the solar energy is harnessing the sun’s heat energy in the life of human beings.

It can be used domestically, such as for cooking (stoves, solar) to generate hot water (SWH) or for heating. It is also used at industrial level, where water is heated to evaporate the water vapor moves turbines to generate electricity (solar thermal power plants).

Using more is now known that solar energy is thermal solar water heaters for domestic use. These consist of two main parts, the solar collector and storage tank. The solar collector is a box about 2 m2 in which there is a series of tubes through which water, which when in contact with the sun is heated, a hot time is stored in the storage tank (a tank insulated like a thermos), where it remains hot for when needed. These heaters can produce up to 91% of hot water consumed by a family, depending on usage and the amount of sun that is in the location of the heater.

Another use of solar thermal energy is taking a lot of momentum inside the houses are solar cookers, as they are very cheap (you can build one in your house) and easy to use. A solar cooker can cook rice in about an hour and a whole chicken in 3 or 4 hours, so that gas use is reduced significantly and immediately in households that use them.

Within the branches of solar energy, solar power is cheaper than PV, so the energy is more support and growth has in recent years.

As we said, solar thermal energy can also be used to generate electricity. This is done by building a tower on top of which there is a giant tank of water around the tower is placed thousands of mirrors that face the tank so the water is heated and evaporates, the vapor is forced to pass through turbines to generate electricity. At night the water condenses and fills the tank so the next day re-generate clean electric power.
