On Saturday my new PV system modules had seagull poo on them (nothing else produces that much).\u00a0 I climbed on the shed roof and cleaned it off.\u00a0 By Monday they had done even more.\u00a0 It was due to rain and so I left it.\u00a0 For once heavy rain was useful -its all gone.\u00a0 This system is almost horizontal so needs some cleaning.\u00a0 The old system is at 27 degrees to the\u00a0horizontal and tends to self clean, although I have got moss growing on the edge of the frames now.\u00a0 Its difficult to know how much difference poo makes to power output but must make some, although its not the major problem that I heard someone say it was on the radio (the implication being PV wouldn’t work because of bird poo).<\/p>\n
