Inspecting Solar Panels using a Drone

I’m probably not the first to do this – but it was a fun way to learn just how tricky it is to control a cheap quadcopter even in mild weather.

This video has no sound.

Good enough quality to make sure the panels aren’t covered in bird-mess, leaves, or anything else which might block their efficiency.

Thanks to Jack Franklin for the drone.

  1. a) I love a bit of solar panel porn, bring it!
    b) it’s non-trivial how much generation capacity you can lose from bird droppings, worth the bother to do this.

    At that angle the panels should self-clean on your property, but odd things can happen. Early in the life of our first row of panels, I noticed the power generation drop off considerably – we lost 15% of generation. It turned out one panel was approx. 1/3 covered in bird poo from a defunct TV aerial which overhung it. That is enough to shade the panel enough that its internal resistance builds up – this kills the output from that panel, and can even harm it. We had the TV aerial removed, the panels scrubbed, and the lot has stayed clean for 9 years now!

      Nice! The original instructions I got with the panels suggest that I clean them off with water at least once per year. I’m guessing the British rain takes care of that!
