How do you run a single phase motor using solar panels?

Answer 1

you would need a motor starter/contactor with the contactor coil rated at your control voltage. the motor is wired through the contactor main contacts and the control circuit wired into the contact coil

Answer 2

This is a perpetual motion theory. It does not happen, as there are more losses in this type of connection to over come, to turn it into an operating system. People have been trying for years to achieve this type of operation. So far no one has succeeded.

Answer 3

This will be a very expensive project. Solar panel outputs are DC whereas single phase motors are AC. First you will need join enough solar panels together to bring the voltage up to what the motor operates on. Most solar panels voltage output is 12 VDC. Due to the start up amperage of the motor you will need a battery bank to allow for the inrush current to the motor. The solar cells are only used to keep the battery bank charged. Now to change the DC to AC an inverter will be needed with a capacity to handle the inrush current of the motor. Most smaller motors, the inrush current will be 250 to 300% times the motors full load amperage. This amperage will be found on the motor's nameplate.

Solar panel installations now fall within the electrical code book guide lines. An electrician will need to be consulted for correct wire sizing and for proper installation of current protection devices to keep the within the safety guidelines. With all of this equipment needed you can now see why this is a very expensive project.
