SOLAR TECHNOLOGY. HEAT FROM THE SUN.

Solar radiation is the energy that flows between the sun, the atmosphere and the earth. Without the atmosphere, in many technical applications the spectrum of light from the sun would be spread and then absorbed in the same way a black body absorbs radiation, at a temperature of 6000 K. The intensity of radiation is regulated by the atmosphere: a part is reflected back into space, another part is dispersed by atmospheric gas and water vapor molecules and the rest is absorbed by the atmosphere, which in turn produces infrared rays.

Photovoltaic technology enables the energy from solar radiation to be converted directly into electricity through the use of materials that have the properties of semiconductors and after specific treatment have the capacity to generate electricity when exposed to the sun.

Solar energy can also be used for water and ventilation systems as well as water heating.
