Thermal solar energy and Photovoltaic ENERGy


Thermal solar energy

Photovoltaic ENERGy

The main element of a thermal solar installation is the collector which is exposed to the sunlight.

The collector, in its turn, is composed by the absorber which absorbs sun radiations in order to transform them in heat.

The heat produced in the absorber is then transferred to a tank containing water. The accumulated warm water is then exploited for medical use or for low-temperature heating systems.

This kind of installation can be implemented wherever there is a high consumption of hot water: homes, schools, hospitals, rest homes, public offices, sports facilities, swimming pools.






How does it work

The photovoltaic effect is the basic physical process through which a solar cell converts sunlight into electricity.

Photovoltaic sun technology is based on the properties of certain semiconducting materials, such as silicon which can convert solar radiation energy into electric energy.

The basic element of a plant is the photovoltaic cell. When sunlight hits the cell a continuous electric current is generated which can be compared to a low-voltage pile. Several cells connected in series form a single structure called photovoltaic module which is the basic element of the photovoltaic system.


Photovoltaic plants have several advantages:


         Absence of any kind of polluting emissions

         Saving of fossil fuel

         Product life of about 20 years

         Very low maintenance costs

         Less expensive bills

         Recovery of the investment
