Keep those solar panels clean dudes.
That's not exactly true , if the panel is 10% occluded by dirt and grime evenly distributed the lose of power is just 10% ..

But if one cell of the panel is covered by a big leaf or something then all the other cells in the panel (aprox 40 cells) can't deliver , because they're wired in series ...also this panel maybe connected in series with another panel which will also go down, even if perfectly clean ..

So evenly distributed dirt not too bad , but concentrations in one area , or patches of leaves can stop everything.
