dust measuring mechanisam on pv panel

Dulithk

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 is a loss of light, due to dust/dirt.

    The light sensor could be a small solar panel, but it might be easier to use a proper light sensor with a digital output, since you'll need a microcontroller anyway to activate the daily cleaning operation.
