What Size Solar Panel To Run A Fan

The beginning stages of research with solar power is always how much power with how many panels.

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. It s a question that comes up often for those looking into smaller scale solar installations. Add their power draws in watts. 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. 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.

If it is listed in watts divide by 12 to find a. With amps you take the sum of the currents that each fan will draw givi. Size of fan and solar panel. Running solar direct you need to pay more attention to the imp voc and vmp.

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. A fan that s too large may dwarf the room and a poorly placed solar panel can be an eyesore. The total watt hours per day of energy you ll need.

What can you run with a 100 watt solar panel. Define your peak instantaneous power output measured in watts. 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. 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.

Here is a more in depth look into what a 100 watt panel is and what its best uses are. Compile a list of all your appliances and devices and how many hours per day each will be run. Solar panels are sold in varying sizes but a 100 watt panel is a commonly found size particularly for rvs. And it is really great that you re thinking of using solar.
