Arcobaleno - Solar panels

Uses
The Arcobaleno solar panels can be used in closed circuit hot water production systems for sanitary use, for heating swimming pools, as well as for pre-heating or completion of room heating, for example in the case of the use of radiating panels. The fields of use in construction, both public and private, run the range from wellings to common areas, from the tourism/lodging sector to manufacturing activities.
For temperatures below 0 °C, as a heat-carrying fluid in the solar panels a water-antifreeze solution must be used with a concentration that is suitable to prevent damage from freezing. The solar collectors must be firmly attached and installed incompliance with current standards.
Optimal inclination varies depending on use.
The orientation of the collectors must be towards the equator (southeast since the afternoon hours are the warmest).

Utility
The initial investment for the creation of a solar energy system is rewarded by the fact that there are practically no operating costs. The only energy expenses are the electrical energy used by the circulating pump (if there is one).
Considering the current costs and the continuing increases in traditional energy sources (methane, LPG, fuel oil), the use of a solar energy system is fully justified, now more than ever.

Norms
Arcobaleno solar panel type "NS", "SRTO", "SRTV", "SXM" and "SXE" are certified UNI EN 12975-1 and UNI EN 12975-2.
