The basic principle of a solar collector is to pick up the heat of the sun to heat the water.
To have good outputs is necessary to minimize the dispersions. For every person it is necessary an installation of 1 or 2 mqs. of panel in relationship to the exposure and the geographical position.
The plate is composed from small pipes, in which the water, that is settled to a plate of absorbent surface flows.
In the pipes a small quantity of water that easily heats him flows.
In the inferior and superior part of the plate they are found the pipes that bring the cold water to the panel and they pick up the warm water in exit. Above the plate a plate of glass is set antigrandine that limits the dispersions of heat creating an equal effect to that that realizes him in a greenhouse.
Under the panel a layer of insulating material is systematized for preventing that the picked heat disperses him on the roof.
The insulating material is covered by an aluminum layer that reflects the heat toward the plate.
Heated water is sent to the reservoir of accumulation in series with the boiler and through a pomp it allows the circulation of the water in the sanitary plant.        The solar panels system cannot be used every day of the year of facts, in the winter months, with the covered sky the system is integrated the with the use of a traditional heating system, however it is advantageous for a saving that is distributed within one year.
