Anybody here to suggest a method (sensor) to measure dust on a glass surface (photo voltaic) without going to image processing? #help

Hi, Wouldn't a couple of light sensors work? One that is wiped (say) daily using an electric motor, acting as the reference light level. If there's significant difference between the two, then there…

A variation on what Shabaz is suggesting is to shine a light onto the surface at a shallow angle so that most of the light is reflected towards a light sensor. Make sure the light sensor is shielded so…

I think this this is an XY problem. Wouldn't just knowing that there is a decline in photovoltalic output power for a given solar irradiance, be enough to determine something is suspect. I.e. wouldn't just a pilot cell (perhaps one that is self cleaning) or a power senor be enough?
