What happens if there is a leak in the panel?

Edited

The DualSun panel has undergone numerous accelerated ageing tests to guarantee that the heat exchanger will not have any leak issues.

In the case a leak does occur, we must remember that the DualSun panels have successfully passed the complete set of electric tests associated with the photovoltaic certification (IEC 61215 and 61730), taking in consideration the combined PV/T aspect of the DualSun panel. In fact, DualSun is the first panel in the world to integrate the "hybridisation" aspect of the panels in the certification tests.

Furthermore, an important test including in the certification ("Wet leakage current test") which includes full immersion of the panel in water, confirms that the DualSun panels maintain full electric operation, even in full contact with water and humid conditions.
