The total watt hours per day of energy you ll need.

What size solar panel to run a fan.

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. Small solar panels yet you can also find panels of 150 160 or 175 watts. Add their power draws in watts. Define your peak instantaneous power output measured in watts.

Solar panels of this size are often paired with some form of battery storage. Compile a list of all your appliances and devices and how many hours per day each will be run. Figure out the duty cycle. Equally important as the space the fan can cool is the space the fan takes up.

If it is listed in watts divide by 12 to find a. 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. This allows you to store excess energy and use it when needed. Determine which appliances you ll be running at the same time.

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. 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. A fan that s too large may dwarf the room and a poorly placed solar panel can be an eyesore. With amps you take the sum of the currents that each fan will draw givi.

What can you run with a 100 watt solar panel. Solar panels are sold in varying sizes but a 100 watt panel is a commonly found size particularly for rvs. It s definitely a smart way to go. It s a question that comes up often for those looking into smaller scale solar installations.

Running solar direct you need to pay more attention to the imp voc and vmp. Here is a more in depth look into what a 100 watt panel is and what its best uses are. For example a weekend cabin used for two days has a duty. The size of the solar panel can also affect the fan s performance.
