Open circuit 20.88V voltage is the voltage that comes directly from the 36-cell solar panel. When we are asking how many volts do solar panels produce, we usually have this voltage in mind. For maximum power voltage (Vmp), you can read a good explanation of what it is on the PV Education website.
Maximum Power Voltage (Vmp): This is the sweet spot voltage where your panel produces the most power (usually between 18V and 36V). Your system should try to operate at this voltage. Nominal Voltage: These are standard classifications like 12V, 24V, or 48V that help match panels with batteries and other equipment.
It shows your solar panel's rated voltage output. Common values are 12V, 18V, 20V, or 24V. Keep in mind that the collective voltage of an array changes depending on the setup. When going solar, consider these three types of voltages. They will help you make an informed decision. You may have noticed that solar panels come with an efficiency rating.
As we can see, solar panels produce a significantly higher voltage (VOC) than the nominal voltage. The actually solar panel output voltage also changes with the sunlight the solar panels are exposed to.
Voltage output directly from solar panels can be significantly higher than the voltage from the controller to the battery. Maximum Power Voltage (Vmp). The is the voltage when the solar panel produces its maximum power output; we have the maximum power voltage and current here. Here is the setup of a solar panel:
To understand solar panel voltage more clearly, it's important to also consider wattage, which refers to the total power output of the solar panel. The wattage of a panel is a result of the combination of voltage and current (measured in amps).
