It s definitely a smart way to go.
What size solar panel to run a fan.
Define your peak instantaneous power output measured in watts.
Figure out the duty cycle.
Determine which appliances you ll be running at the same time.
If it is listed in watts divide by 12 to find a.
Solar panels of this size are often paired with some form of battery storage.
The size of the solar panel can also affect the fan s performance.
Compile a list of all your appliances and devices and how many hours per day each will be run.
Size of fan and solar panel.
On the fan case or motor face you will see a rating for amperes or watts as well as the rated voltage you said 12vdc.
Add their power draws in watts.
For example a weekend cabin used for two days has a duty.
With amps you take the sum of the currents that each fan will draw givi.
Running solar direct you need to pay more attention to the imp voc and vmp.
Voltage range of 12 28vdc you want a solar panel with as close to a voc of 28v as possilble without going over and a vmp of at least the midpoint of the range.
Equally important as the space the fan can cool is the space the fan takes up.
Small solar panels yet you can also find panels of 150 160 or 175 watts.
What can you run with a 100 watt solar panel.
Those solar panels used for residential purposes range from 150 watts to 370 watts per panel depending on the panel size efficiency and cell technology.
This allows you to store excess energy and use it when needed.
And it is really great that you re thinking of using solar.
Here is a more in depth look into what a 100 watt panel is and what its best uses are.
Solar panels are sold in varying sizes but a 100 watt panel is a commonly found size particularly for rvs.
A fan that s too large may dwarf the room and a poorly placed solar panel can be an eyesore.
It s a question that comes up often for those looking into smaller scale solar installations.
