Nominal Voltage Of Solar Panel

Open circuit voltage or v oc is the maximum voltage that the module can produce when not connected to an electrical circuit or system.

Nominal voltage of solar panel.

Is there a way to determine the nominal voltage of a solar panel. In typical practice pwm panels arrays for 24 volts and higher would be built out of series strings of 12 volt panels rather than higher voltage panels. Nominal voltage is a category to let users know if two pieces of equipment will work together. It is used to charge a 12v battery which is actually around 14v.

Solar panels usually range in wattage output from around 250 watts to 400 watts but some panels exceed the 400 watt mark. The solar panel with the highest watt is the sunpower e series a commercial solar panel line. So in that specific sense a panel with 36 silicon cells and a vmp of 18 volts would be called a nominal 12 volt panel. A solar cell is an illumination based current source that is clamped in maximum voltage by the forward biasing of its inherent diode.

The peak power of solar panels is registered under the following standard test conditions. For example a nominal 12v solar panel has a voc of about 22v and a vmp of about 17v. A 72 cell 36 volt panel would be nominally 24 volts. Nominal voltage is a category.

A current source is a high impedance source not like a battery or other voltage sources that have low driving impedance. For example a 14v solar panel is compatible with a 14v battery bank. The top panel in the e series comes out at a whopping 435 watts. Nominal voltages let people know what equipment goes together.
