What Size Solar Panel To Run A Fan

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 size solar panel to run a fan.

Determine which appliances you ll be running at the same time. 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. Solar panels are sold in varying sizes but a 100 watt panel is a commonly found size particularly for rvs.

What can you run with a 100 watt solar panel. For example a weekend cabin used for two days has a duty. This allows you to store excess energy and use it when needed. It s definitely a smart way to go.

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. It s a question that comes up often for those looking into smaller scale solar installations. And it is really great that you re thinking of using solar.

Compile a list of all your appliances and devices and how many hours per day each will be run. 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. The beginning stages of research with solar power is always how much power with how many panels. A fan that s too large may dwarf the room and a poorly placed solar panel can be an eyesore.

Here is a more in depth look into what a 100 watt panel is and what its best uses are. Solar panels of this size are often paired with some form of battery storage. 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.

Figure out the duty cycle. The total watt hours per day of energy you ll need. Add their power draws in watts. With amps you take the sum of the currents that each fan will draw givi.
