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.
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.
The state of charge (SOC) determines how much energy a battery holds. When fully charged, a 12V battery may show a voltage reading of 12.6 to 13.2 volts. As the battery discharges, this voltage decreases.
Solar Batteries are available in a few common voltage sizes. The most common voltage used for solar batteries are 6V, 12V, 24V and 48 Volts. What is Voltage? Voltage, also called electromotive force, is a quantitative expression of the potential difference in charge between two points in an electrical field.
