6 FAQs about [Changes in open circuit voltage of photovoltaic panels]
What is open-circuit voltage in a solar cell?
The open-circuit voltage, V OC, is the maximum voltage available from a solar cell, and this occurs at zero current. The open-circuit voltage corresponds to the amount of forward bias on the solar cell due to the bias of the solar cell junction with the light-generated current. The open-circuit voltage is shown on the IV curve below.
Are solar photovoltaic cell output voltage and current related?
Through the above research and analysis, it is concluded that the output voltage, current, and photoelectric conversion rate of solar photovoltaic cells are closely related to the light intensity and the cell temperature.
How does light intensity affect the trough solar photovoltaic cell?

Does solar panel temperature affect voltage?
Panel temperature will affect voltage – as has been discussed in another blog. Have a look at these I-V (Current vs Voltage) and P-V (Power vs Voltage) charts for a 305W solar panel from Trina Solar. You can see in the P-V curve that as the solar radiation decreases from 1000W/m2 to 200W/m2, the power drops proportionally – from 300W to 60W.
