You can use the inexhaustible solar source freely to support operation of all kinds large scale ventilating fans, the regular commercial electricity bill in old days is no longer a must pay.
The solar modules mounted on roof-top will generate electricity to support the fans working.

24 Volt 300W Industrial Use Large-Scale Solar Powered Ventilation System for Building with  Dia. 950mm Fan Blade  (SN2013021)


You can add a Mains Switch Controller into product to hybrid use the solar panel supply and public electricity supply to have the ventilating fans work continuously after dark or in cloudy periods.

Fan motor we used is brushless DC motor, so when our products are working under consumption of commercial electricity, their energy costs are still much smaller than those traditional AC motored ventilating fans.


The primary power supply for product to work is always from solar panel, only when the sunlight illumination intensity on solar panel is too weak to function fan motor, the Mains Switch Controller will switch-on public electricity supply as support.
Hereafter illustrates the Mains switch mechanism between solar panel supply and public electricity supply, all switches can be realized automatically intelligently by the Mains Switch Controller.

AC electricity as power supply:
