We noticed that the output of our solar panels had suddenly dropped over the last couple of very sunny days, from a maximum of about 1.3kW to a maximum of 900 watts. We sent the drone up for a look and saw this at around midday: the outlined area is now in shadow as the sun gets lower, and just that tiny amount of shading cuts nearly half a kilowatt from the output.
