If the panel has 72 solar cells in series and each cell has a voltage of 0.6V, the theoretical Voc is 43V. Here's a simple table that takes you through the different types of voltages for different wattage solar panels: 30V for a 60-cell panel with 0.5V solar cell output. 36V for a 72-cell panel with 0.5V solar cell output.
Solar panel output voltage typically ranges from 5-40 volts for individual panels, with system voltages reaching up to 1500V for large-scale installations. The exact voltage depends on panel type, cell count, temperature, and sunlight intensity.
To be more accurate, a typical open circuit voltage of a solar cell is 0.58 volts (at 77°F or 25°C). All the PV cells in all solar panels have the same 0.58V voltage. Because we connect them in series, the total output voltage is the sum of the voltages of individual PV cells. Within the solar panel, the PV cells are wired in series.
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.
