The two principle voltages are Voc and Vmp (Voltage Open Circuit and Voltage Maximum Power). Voc is when there is no load on the panel, this is usually about 21.6V (0.6V per cell x 36 cells = 21.6V) for a 100W panel. Vmp is the voltage at which the maximum power is generated (see below), this is usually around 18.5V for a 100W panel.
The Open Circuit Voltage (Voc) rating of a solar panel, on the other hand, indicates the voltage measured across the panel''s terminals under ideal conditions when no load is connected. For instance, as shown in the image above, my solar panel has a Voc of 22.5 Volts.

A 24V solar panel typically has an open-circuit voltage (Voc) of approximately 46V. After learning this, let''s also try to find out what is the Voc on a 100 Watt solar panel. What is the Voc on a 100 Watt Solar Panel? The Voc (open-circuit voltage) of a 100 watt solar panel can vary on the basis of the specific model and manufacturer.
The Concept of Open-Circuit Voltage and Its Measurement. Open-circuit voltage (Voc) is the maximum voltage a solar panel can produce when it is not connected to a load or operating circuit. It represents the potential difference between the positive and negative terminals of the panel under open-circuit conditions. Measurement:

If you know the number of PV cells in a solar panel, you can, by using 0.58V per PV cell voltage, calculate the total solar panel output voltage for a 36-cell panel, for example. You only need to sum up all the voltages of the individual photovoltaic cells (since they are wired in series, instead of wires in parallel). Here is this calculation:
12V or 24V is actually not the true voltage of the solar panel. It is the nominal voltage that is given for the purpose of designating the solar panel. Basically, it''s a convenient number to make it easier to identify the type of solar panel. If you have a 12V battery, you know you need a 12V solar panel. The actual voltage of a solar panel
A 24 volt panel works at around 32 volts and its open circuit voltage is around 45 volts. So you can see that the voltage of a panel can be confusing. With an 18 volt panel, you can put more of the panels in series without getting too high a voltage for a charge controller or an inverter, and at the same time you get more amps — and it is the
