Learn MoreWhen talking about solar panel output voltage, it's essential to get the definitions straight as voltage can refer to many things: Nominal voltage is not actual voltage but rather a category or classification that is more related to the battery that will be charged.
This might sound weird, but both are correct and useful: Nominal 12V voltage is designed based on battery classification. With solar panels, we can charge batteries, and batteries usually have 12V, 24V, or 48V input and output voltage. It is the job of the charge controller to produce a 12V DC current that charges the battery.
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.
Solar batteries are typically 12V, 24V, or 48V, with a fully charged 12V battery reading between 12.6V and 12.8V. Voltage readings below 12.4V for a 12V battery indicate a partially discharged state that may require recharging.
The main purpose of understanding voltage in solar power is to ensure compatibility between various components. If you have a 12V battery, then you can only charge it with a 12V solar panel. You'll also need a 12V inverter and a minimum 12V charge controller. If you want a 24V setup, then everything needs to be 24V across the wiring.
