How does temperature affect the voltage output of a PV panel?

The voltage output is greater at the colder temperature. The effect of temperature can be clearly displayed by a PV panel I-V (current vs. voltage) curve. I-V curves show the different combinations of voltage and current that can be produced by a given PV panel under the existing conditions.

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.
