The solar ceiling exhaust fan here is a developed version from its basic day-working system (#SN2016025) into a Day-Night Nonstop working system (#SN2016026). If grid electricity is available in your location, and you need the fan to continuously always ventilate the house, please take and install this system.
Or, another system that contains battery to realize nonstop running at night while totally free from energy charges: #SN2016027!
Fan Part: ceiling mounted, with a flat louver
* solar panel is the major power source, and it will be the only power supplier as long as its output is sufficient to run the fan
* AC/DC power adapter is the backup power source, and it will be consumed only when sunlight is not available
* there is the chance that solar panel is working together with AC/DC power adapter to supply power to the fan, however, solar panel is still of priority, and AC/DC power adapter is still as backup only
Controller Part:
if solar panel is supplying direct power at X%
AC/DC power adapter will be at (100-X)%
* there is an inbuilt controller inside the junction box to take care of the power supplies between solar panel & AC/DC power adapter
- you don't need to do any manual shifting operation
- you don't need to worry about any unnecessary energy consumption
* fan blades are in centrifugal type, with strong suction capacity and suitable for long distance air ventilation
* fan blades are in plastic quality, performing super quietly
* since centrifugal type air ventilation, you can add pipelines to guide the extracted air / heat outside
* you can even use a vent joint to combine 2 pipelines from 2 fans to share 1 outlet
