Click "Calculate Max Voltage": After you've filled in all the necessary fields, hit the "Calculate Max Voltage" button. Read the Results: The calculator will then display the maximum voltage that your solar panel array can theoretically produce under the conditions you specified.
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.
To estimate the maximum Voc, multiply the solar panel voltage by the correction factor corresponding to the lowest expected temperature: maximum Voc = solar panel voltage (Voc) ∗ correction factor If the solar panels have the same Voc, then this one calculation should do.
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.
