Assuming a typical 60-cell solar panel with a Voc of 37V, the maximum design voltage is 44.77V.The second method requires using an equation and referencing the temperature coefficient of voltage found on the solar panel data sheet, but it gives a more exact answer than using NEC Table 690.7.

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.
Lastly, the quantity of modules wired in series multiplied by the VMax equals your maximum system voltage. 13 x 43.54 V = 566 Maximum System Voltage Voilà, we’ve determined the max PV voltage for our example system and are able to ensure a proper system design without fear of over-voltage for the inverter.
36-Cell Solar Panel Output Voltage = 36 × 0.58V = 20.88V What is especially confusing, however, is that this 36-cell solar panel will usually have a nominal voltage rating of 12V. Despite the output voltage being 18.56 volts, we still consider this a 12-volt solar panel.
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.

Solar array mounted on a rooftop. A solar panel is a device that converts sunlight into electricity by using photovoltaic (PV) cells. PV cells are made of materials that produce excited electrons when exposed to light. These electrons flow through a circuit and produce direct current (DC) electricity, which can be used to power various devices or be stored in batteries.
Voltage output directly from solar panels can be significantly higher than the voltage from the controller to the battery. Maximum Power Voltage (V mp). 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:
