What is the stagnation temperature of the DualSun SPRING panel?
Edited
It differs slightly depending on the model:
Model | Stagnation temperature |
SPRING4 Finned | 70°C |
SPRING4 Insulated | 80°C |
SPRING4 non-insulated | 70°C |
SPRING3 Insulated | 80°C |
SPRING3 non-insulated | 70°C |
This was measured during TÜV certification tests in accordance with ISO 9806 (ex EN 12975-2) for Solar Keymark certification, with an irradiation of 1000 W/m² and an ambient temperature of 30°C.
There is no overheating on the SPRING panel because there is no concentration of rays as in solar thermal or greenhouse effect.
