This allows you to store excess energy and use it when needed.
What size solar panel to run a fan.
Equally important as the space the fan can cool is the space the fan takes up.
Here is a more in depth look into what a 100 watt panel is and what its best uses are.
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.
It s definitely a smart way to go.
That panel is rated at 100 watts at peak efficiency meaning on a 78 degree cloudless day at solar noon on the equator during the equinox.
Size of fan and solar panel.
It s a question that comes up often for those looking into smaller scale solar installations.
Determine which appliances you ll be running at the same time.
Solar panels are sold in varying sizes but a 100 watt panel is a commonly found size particularly for rvs.
Small solar panels yet you can also find panels of 150 160 or 175 watts.
Running solar direct you need to pay more attention to the imp voc and vmp.
The total watt hours per day of energy you ll need.
Figure out the duty cycle.
Define your peak instantaneous power output measured in watts.
With amps you take the sum of the currents that each fan will draw givi.
The size of the solar panel can also affect the fan s performance.
If it is listed in watts divide by 12 to find a.
For example a weekend cabin used for two days has a duty.
A fan that s too large may dwarf the room and a poorly placed solar panel can be an eyesore.
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.
What can you run with a 100 watt solar panel.
Compile a list of all your appliances and devices and how many hours per day each will be run.
Solar panels of this size are often paired with some form of battery storage.
And it is really great that you re thinking of using solar.
