Operation of thermal solar panels

Thermal solar panel or collector converts the sun's radiation into heat.

Structured absorbers with a selective layer are used in flat or vacuum tube collectors, which determine a high degree of energy absorption (absorption> 0,95 - in the wavelength range of solar radiation), which is then transferred to the heat transfer fluid.

A good thermal contact between the absorber and the heat transfer fluid, guaranteed by the hydraulic circuit attached or belong to the absorber (for example water, glycol or air), allows the supply of heat to the heat transfer fluid and thus the transport out from the collector of heat ready for use.

emptying solar systems operation

New technologies for solar and emptying optimize the yield and improve the solar thermal system security. The technology Drain Back born to avoid during the winter period of the fluid freezing dangers inside the manifolds and in the summer the system from overheating.
When the solar heating system reaches the maximum temperature, the heat transfer fluid present inside the collectors flows in the SolBox tank.
Emptying occurs even in cases of system off or at rest. In this way there is the danger that the mixture of brine into the collectors suffer deterioration due to the high temperatures.

Applications

Solar thermal for heating home

Solar thermal systems with Rossato panels can give a good contribution to the system of heating even in winter weather. 

On average, the collectors are able to cover a large part of the annual energy requirement for heating, while the remainder must be supplied by a generator, such as eg. a boiler, a heat pump, etc. They can also be integrated with common radiators.

Solar thermal and radiant systems

The solar collectors are adapted in a perfect way to Rossato radiant panels for maximum energy efficiency.

The use of low temperatures in the radiant panels increases both for yield than that of the heat pump.
