Photovoltaic Effect: Solar panels generate electricity through the photovoltaic effect. When sunlight strikes the solar cells, photons (light particles) excite electrons, creating an electrical potential difference (voltage) across the cell. Whether you're. . This is the maximum rated voltage under direct sunlight if the circuit is open (no current running through the wires). This sounds a bit weird, but it's really not. The circuit is open as there is no load, so there is no flow of current. A multimeter is connected at the terminals of the solar panel. . Solar panel output voltage typically ranges from 5-40 volts for individual panels, with system voltages reaching up to 1500V for large-scale installations.
