Flat solar panels
Arcobaleno solar collectors (panels) are used in closed-circuit solar systems for producing hot water for sanitary use, heating swimming pools, or even for preheating or integrating space heating systems, for example, in the case of the use of radiant panels.
Construction fields of usage, both public and private, span from residences to communities, from the tourism/hotel sector to manufacturing operations.
When operating at temperatures below 0 ° C, a suitable water-antifreeze solution must be used as the heat transfer fluid inside the solar panels to prevent freezing damage. In addition, solar collectors must be securely fastened and placed by current requirements. Depending on the use, a different inclination is ideal.
The collectors must be pointed in the direction of the equator (in any case, the southwest orientation is preferable to the southeast one since the afternoon hours are warmer).
