The voltage of a solar panel is the result of individual solar cell voltage, the number of those cells, and how the cells are connected within the panel. Every cell and panel has two voltage ratings. The Voc is the amount of voltage the device can produce with no load at 25º C.
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.
Think of voltage as the pressure in a water pipe; the higher the pressure, the more water flows through the pipe. In the context of solar panels, voltage is crucial because it determines how much potential energy the panel can generate. Different solar panels have varying voltage ratings, typically ranging from 12V to 48V.
Nominal voltage is an approximate solar panel voltage that can help you match equipment. The voltage is usually based on the nominal voltages of appliances connected to the solar panel, including but not limited to inverters, batteries, charge controllers, loads, and other solar panels.
Measuring volts is a fairly simple procedure. A simple Voltmeter or Multi-meter from your local hardware store is all you need. Set the meter to DC Volt in the appropriate range. Touch the probes of the meter to bare wire at the end of the cables and you can measure the voltage of the panel. Be careful not to let wires touch each other.
Touch the probes of the meter to bare wire at the end of the cables and you can measure the voltage of the panel. Be careful not to let wires touch each other. To calculate the power (watts) provided by a solar panel we need to know the size of the electrical wave (volts) and the force of the current (amps) behind the wave.
