What if a solar panel shows voltage but no current?

What is a solar panel voltage?

Open Circuit Voltage (Voc) is the maximum voltage of the solar panel when the current is at zero. Short Circuit Current (Isc) is the maximum current of the solar panel when the voltage is zero. Maximum Power Voltage (Vmp) is the maximum voltage when there is a current. Maximum Power Current (Imp) is the maximum current with a voltage.

How do you measure solar panel current?

Using a multimeter here are the steps you would take to measure the solar panel current: Set the multimeter to read amps. Connect the positive to negative leads of the solar panel. Position the solar panel in the sun. Pass the clamps of the multimeter through the connection to get the reading. Why Is Solar Panel Current Low?

How does voltage affect a solar panel?

Voltage is the electromotive force that makes current happen in a solar panel. When you open a tap, the pressure causes the flow of water. The same concept applies in electronics except here the pressure is voltage. Voltage pushes current from a solar panel to either a battery or inverter or directly to an appliance.

Why does current not flow from a solar panel to a battery?

For current to flow there should be a difference between the source and the destination voltage. Current flows from high voltage to low voltage. For example, if a solar panel has a voltage of 5.5V and a battery is 12V, current will not flow from the solar panel to the battery. The problem can also be caused by a faulty charge controller.
