You can power an AC fan for ventilation purposes using solar energy. When doing so, use an inverter capable of operating without a battery. The inverter converts the DC electricity generated by the solar panel into AC electricity that can be used by the fan. This simple type of system does not require a battery.
Things You'll Need
- Wire nut
- Electrical wire
- Solar panel
Disconnect any live electricity that may be connected to the fan.
Remove any old AC wiring. Screw a wire net onto the end of the wire to prevent shock.
Secure the inverter as close as possible to the solar panel. To secure it, screw it to a supporting structure such as a roof rafter. Ensure that you protect the inverter from inclement weather.
Connect wires from the positive and negative terminals of the solar panel to the positive and negative DC inputs on the inverter.
Connect the new AC wiring between the inverter and the fan.
Tips & Warnings
- Always follow your local electrical codes when installing permanent electrical equipment.
