Can DualSun panels be used only for photovoltaics (without fluid inside)?
Yes, our DualSun hybrid panels (Wave or Spring) can be used solely for photovoltaic electricity production without using water heating. This is obviously not its primary function, as only half of the panel’s potential is used in this case, but it’s technically possible.
This is the case, for example, with swimming pool heating installations: in the winter the panels must be emptied to avoid any risk of frost. Photovoltaic production, on the other hand, continues to function without problems.
