About Output voltage of photovoltaic panels under different light conditions
When the light intensity reaches 150 W/m 2, the output voltage of the maximum power point of the photovoltaic cell quickly climbs from 200 V to about 300 V. when the light intensity is greater than 200 W/m 2, with the increase of the light intensity, the voltage is approximately the same, and it fluctuates at about 340 V.

In this paper we mainly focus on effect of PV output for different color of visible light. Visible of sun is the combination of six color and each color of light have different wavelength. So our prime concern is how PV cell affected by this six color of visible light.
Effect of Light Intensity. Changing the light intensity incident on a solar cell changes all solar cell parameters, including the short-circuit current, the open-circuit voltage, the FF, the efficiency and the impact of series and shunt resistances. The light intensity on a solar cell is called the number of suns, where 1 sun corresponds to .
Here’s what we learned: Solar panels, unless heavily shaded have a remarkably high and consistent voltage output even as the intensity of the sun changes. It is predominantly the current output that decreases as light intensity falls. Panel temperature will affect voltage – as has been discussed in another blog.
