What size solar panel to run a fan.

Running solar direct you need to pay more attention to the imp voc and vmp. It s a question that comes up often for those looking into smaller scale solar installations. It s definitely a smart way to go. The beginning stages of research with solar power is always how much power with how many panels.

Solar panels of this size are often paired with some form of battery storage. If it is listed in watts divide by 12 to find a. And it is really great that you re thinking of using solar. What can you run with a 100 watt solar panel.

Small solar panels yet you can also find panels of 150 160 or 175 watts. Solar panels are sold in varying sizes but a 100 watt panel is a commonly found size particularly for rvs. Equally important as the space the fan can cool is the space the fan takes up. Figure out the duty cycle.

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. The size of the solar panel can also affect the fan s performance. 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. This allows you to store excess energy and use it when needed.

For example a weekend cabin used for two days has a duty. Add their power draws in watts. Size of fan and solar panel. Define your peak instantaneous power output measured in watts.
