By collecting solar radiation properly, we could get heat and electricity.

The heat is achieved through the use of solar thermal collectors, and electricity through the photovoltaic modules. Both processes have nothing to do with each other, nor as to its technology or its implementation.

Let’s talk first heat utilization systems. The heat collected in the sensors can be used to meet many needs. For example, you can get hot water for domestic or industrial consumption, or for heat our homes, hotels, schools, factories, etc.. We can even allow pools and air condition the bathroom for most of the year.

Also, although it may seem strange, one of the most promising applications of solar heat is cooling during the warm season, precisely when there is sunlight. Indeed, for cold is necessary to have a “hot source”, which may well be caused by solar collectors installed on the roof or roof. In Arab countries are fully operational and many air conditioners that use solar energy effectively. Read the rest of this entry »

Solar energy is the energy produced by the sun and is converted to useful energy by man, either to produce electricity or heat something (like your main application).

Each year the sun throws 4 thousand times more energy than they consume, so its potential is virtually unlimited.

The intensity of energy available at a given point on earth depends on the day of the year, time and latitude. Furthermore, the amount of energy that can be collected depends on the orientation of the receiving device.

Today is one of the most developed renewable energies and ethod used in the world. Read the rest of this entry »
