Solar Panel Cleaning Equipment

Solar panel cleaning equipment is a soft rotating brush on a telescopic pole, fed with purified water, used from the ground. Panels lose output as they soil, and the loss is worst in dry dusty conditions where no rain washes the surface between cleans.How solar panels are cleanedThe brush is soft and rotates slowly so it lifts dust without scouring the anti-reflective coating. The water is purified first — reverse osmosis or de-ionising resin strips out the dissolved solids — so the panel dries without a mineral film that would shade it again. Detergent is not used, because residue attracts dust faster than a bare panel does.Two things must never be used on an array: a pressure washer, which forces water past the frame seals, and cold water on a hot panel, which risks thermal shock to the glass. Clean early in the morning while the array is cool.Reach and power sourceThe pole kit has 7.5 m of reach, which covers ground-mount arrays, single-storey roofs and most double-storey roof mounts. It is mains powered: a 24 V DC converter runs the 60 cm roller brush off a 240 V power point, so there is nothing to charge and it runs for as long as it is plugged in. It needs a power point within cable reach of the array. The 7.5 m mains-powered kit is R18,270.Prices include 15% VAT. Delivery is a flat R175 anywhere in South Africa.The purified water these kits need is produced by the same equipment that feeds a window-cleaning water-fed pole.Solar cleaning and window cleaning share equipmentA cleaner already running purified water for glass can clean panels with the same purification stage and often the same pole, changing only the head. See pure water systems for reverse osmosis and de-ionising equipment, and water fed poles for the poles themselves.If you are working out how much reach an array or a building needs, that is covered under high reach window cleaning equipment.
