Solar Thermal
and Photovoltaic

Operation:

The system consists of a solar panel, a solar station with a circulation pump, a storage tank for domestic hot water or technical water, an expansion vessel, and a safety group. The solar station detects the temperature inside the solar panels and, if it is more than 8°C higher than the temperature of the storage tank, activates the circulation pump, allowing the hot heat transfer fluid to reach the storage tank and transfer heat through the internal heat exchanger. Circulation is maintained until the set temperature of the boiler is reached or the temperature difference between the panel and the storage tank decreases.

• Greater efficiency in exploiting solar radiation.

• Possibility of integrating the system with other systems, such as a gas boiler or a

  heat pump.

• Greater flexibility in choosing the positioning of the collectors and the tank.

Operation:

The heat transfer fluid circulates by natural convection, exploiting the difference in density between the hot fluid (lighter) and the cold fluid (heavier). The storage tank must be positioned above the collectors so that the hot fluid rises naturally upwards. Alternatively, systems that exploit direct radiation without the use of heat transfer fluids can be used, through a highly selective glass that heats the storage tank integrated into the structure. From an aesthetic point of view, they are much more compact.
