Temperatures inside a switched off solar panel can easily reach 150ºC.

Due to the SolarVenti patent on, among other things, the self-circulating cooling system, the temperature inside the SolarVenti panel never rises above 75ºC, even when it is idle.

Thus, the solar cell and ventilator never overheat. The automatic cooling system ensures that the system can be turned off at any time via a switch or thermostat or, in the event of damage, without impairing the solar cell or ventilator. Simple and safe, as the automatic cooling system does not use electricity and, therefore, always works.

A self-circulating cooling system also keeps the interior of the solar panel clean. With the self-circulation system in the panel on a wall or roof, the ventilator does not need to blow cooling - but “used” - air and even cooking fumes and smoke from inside the home out through the panel which can quickly result in destructive deposits of dirt inside the solar air collector panel.
The self-circulating cooling system also means that there will be excess electricity from the solar cell which, on hot days, can be used to run a well-placed, cooling air injection system elsewhere in the home.

Our patent on the automatic cooling system has also enabled us to place the solar cell’s glass plate solar film discretely inside the panel behind a robust thermal plastic layer which protects against thrown up pebbles. The solar cell releases its own heat into the system which contributes to a very high level of performance per square centimeter.
