Solar Panel Voltage: 2026 Ultimate Guide
Discover the importance of solar panel voltage and how it affects performance. Learn about open circuit voltage, maximum power voltage, and factors influencing solar panel voltage.
Here is the setup of a solar panel: Every solar panel is comprised of PV cells, connected in series. Most common solar panels include 32 cells, 36 cells, 48 cells, 60 cells, 72 cells, or 96 cells. Each PV cell produces anywhere between 0.5V and 0.6V, according to Wikipedia; this is known as Open-Circuit Voltage or V OC for short.
Simply put, voltage (V) is the electrical potential or “pressure” that drives current through your solar system. In solar panels, it's generated when sunlight excites electrons in the photovoltaic (PV) cells. Each solar panel has three key voltage ratings printed on its label: The maximum voltage when no load is connected.
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.
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).
