What is the water temperature at the outlet of a DualSun SPRING panel?
The temperature at the outlet of our DualSun SPRING panels depends on several conditions:
Solar irradiation (denoted as G, in Watt/m²)
Outdoor air temperature
Wind speed
Flow rate circulating through our panels
Inlet temperature of the panels, which depends on the usage (Domestic water heating, solarothermal heat pumps, geothemral probes.
In France, the temperature range of our panels during normal fonctionnement are:
PVT model | Use | Min (°C) | Max (°C) |
Insulated SPRING (SPRING4 425 TOPCon insulated | Domestic heat water | 20 | 60 |
Pressurized pool heating system | 30 | 40 | |
Non insulated SPRING | Geothermal probes coupling | 10 | 40 |
Solarothermal Heat pump (heliopac system+ | -10 | 50 | |
Finned SPRING4 | Solarothermal Heat pump (DHW or heating) | -20 | 30 |
⚠️ Be careful not to confuse outlet temperature and stagnation temperature.
Indeed, in the event that the panel reaches its stagnation temperature, the water leaving the panel would be 70 to 80°C (depending on the SPRING versions). This temperature would drop quite quickly with the transfer of heat to a solar tank or a heat pump for example.
