Solar Fan and Cooler Price in Karachi
Fans are the cheapest way to stay cool on solar. Coolers help in dry heat and much less in humid Karachi air.

Why fans are a good first load
A fan moves air and draws little power. A basic ceiling fan may use around 70 to 80 W, while a DC or inverter ceiling fan uses around 30 to 40 W for similar airflow. Run six fans for ten hours and the gap is large.
Because of that, a modest solar system can keep fans going through a long cut. A small UPS is often enough. See our solar UPS guide.

Fan types compared
Typical running power. Read the label on your own fan.
| Type | Typical power | Fits solar because |
|---|---|---|
| Basic AC ceiling fan | 70 to 80 W | Works, but draws the most |
| Inverter or BLDC ceiling fan | 30 to 40 W | Half the draw for similar air |
| DC fan on 12 or 24 V | 20 to 40 W | Can run straight from a battery |
| Pedestal fan | 40 to 60 W | Moves to where you sit |
Coolers and Karachi humidity
An evaporative air cooler works by evaporating water, and evaporation is slow when the air is already wet. Karachi's humidity averages about 61 percent over the year and is higher in the summer months, around 75 percent in August.
In that air a cooler adds moisture and gives much less cooling than in dry heat. It still moves air and can feel better than a closed room, but do not expect the cooling of an air conditioner.
Coolers draw more power than a fan. Many use a fan motor plus a small water pump. If you want a cooler on solar, check its rated watts and plan the system for it.
Powering fans through a cut
An invented example with six inverter fans.
- 1
Add up the fans
Six fans at 35 W each is 210 W.
- 2
Choose the hours
Run them for 8 hours in the evening and night. That is 1.68 kWh.
- 3
Size the battery
With lithium at 0.9 usable, you need about 1.9 kWh. With tubular at 0.5, about 3.4 kWh.
- 4
Add the lights and router
Another 60 to 80 W for lights and a router raises the figures by about a third.
Do the fan swap before the solar
Changing six old ceiling fans for inverter fans cuts the fan load roughly in half. That can let you buy a smaller battery and fewer panels. It is often the cheapest saving in the whole project, so do it first.

Questions people ask us
Short answers. For your own property, send us your electricity bill and roof details.
Ask on WhatsAppYes. Fans draw little power, and a small solar system or UPS can run several through a long cut.
They use less power than basic AC fans, so they stretch the battery. Inverter and BLDC AC fans give a similar saving.
They help less than in dry places because the air is humid. They move air and add some cooling, but not as much as an AC.
In the day, many, since a fan is about 35 W. At night it depends on the battery.
