We're familiar to the conventional AC type of such wall fans, as they have been commonly used in factories / greenhouses / poultry farms, etc. However, when it is cheap to purchase, it is expensive to use, isn't it?
A dia.1110mm blades / 1220*1220*350mm host / 750W AC unit, product cost may be USD160, but your annual electricity bill may be tripule, or even more:
* if the fan runs 8 hours per day, and local electricity cost is $0.15 per KWH,
* your bill is $0.9/day, say $27/month, and $324/year...
* and, you keep repeating this expenditure every year...
* our DC fan is truely 0 cost for those 8 hours/day
* it is not limited to work for 8 hours, but be as long as you need it to run, given there is energy backup
* when consume necessary grid electricity, it is always higher cost-effective than any AC unit...
If compare the accumulated operation costs, what will you find?
/ | Product Cost | 1st Year Operation Cost (8 hours / day) | 2nd Year Operation Cost (8 hours / day) | 3rd Year Operation Cost (8 hours / day) | Conclusion | |||||
#1 (normal AC fan) | $160 | $160 + $324 = $484 | $160 + $324*2 = $808 | $160 + $324*3 = $1132 | too expensive operation costs | |||||
#2 (new type DC fan) | $888 | $888 + 0 = $888 | $888 + 0*2 = $888 | $888 + 0*3 = $888 | really cost-effective | |||||

#1 (normal AC fan) | $160 | $160 + $972 = $1132 | $160 + $972*2 = $2104 | $160 + $972*3 = $3076 | desperately expensive | |||||

380W/36V, monocrystalline cells
always the mainjor power (as long as sunlight is available)
48'' (1220*1220*350mm), galvanization steeling
unique IP68 Brushless DC motor (no need pullry belt)
electricity wire connections are done here
it smartly shift the power suppliers between solar panel & AC/DC power adapter to the fan
DC output: 36V*8.9A
its input will be used by the fan only when solar panel's input is inefficient
as long as solar panel is efficient to power the fan, commercial grid-electricity through AC/DC power adapter will not be consumed (even if the adapter is inserted into a wall socket)
