PV Array Voltage and Size: What You Need to Know

What Is PV Voltage? PV voltage, or photovoltaic voltage, is the energy produced by a single PV cell. Each PV cell creates open-circuit voltage, typically referred to as VOC. At standard testing conditions, a PV cell will produce around 0.5 or 0.6 volts, no matter how big or small the cell actually is. Keep in mind that PV voltage is different
