    Hey there,

    I'm currently doing my N5 Physics Assignment and my aim is to an investigate the effect of changing irradiance on the output voltage of photovoltaic cells. The only issue is, I'm not quite sure how to measure the irradiance over a photovoltaic cell.

    I know the following: the light intensity of the lamp (lux), the distance between the lamp and the PV cell (m), the area of the PV cell (m^2) and the angle of the PV cell towards the lamp.

    With that information, is it possible to discern the irradiance over the PV cell?
