For most residential panels, Voc typically ranges from: 36 to 45 volts for standard panels. . 650W panels deliver exceptional space efficiency: With efficiency ratings between 20. Installation complexity. . This is your typical voltage we put on solar panels; ranging from 12V, 20V, 24V, and 32V solar panels. This is the maximum rated voltage under direct sunlight if the circuit is open (no current running through the wires). arran enerate up to 600 volts of DC electricity. It is a lab-produced value that has little value in the field. This can be helpful if you're looking to make the move to solar and want to make sure you get the correct voltage rating for your needs.
