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.
Is a smart electricity tariff worth it?
Relaunching @edent_solar. Part 1 - installation
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!
