Regular or one-off cleaning of photovoltaic systems on roofs – for full yield, without stepping on the panels.
Dust, pollen and bird droppings measurably reduce the yield of your photovoltaic system. Cleaning is carried out via rope access directly at the panel, without the system having to be stepped on – this protects the panels and makes even hard-to-reach roof areas accessible. If you also need fall protection for the regular maintenance of your PV system, you can find more on the page Fall Protection & Inspection.
As a rule of thumb every one to two years, depending on location and degree of soiling – with heavy soiling (e.g. from bird droppings or pollen), more frequent cleaning can make sense to avoid yield losses.
No. Cleaning is carried out via rope access directly at the panel, without the system having to be stepped on – this protects the panels and the substructure.
That depends on system size and accessibility. More on the process is on the Pricing & Process page; I put together an exact quote after a short inquiry.
Yes, including large-scale PV systems on industrial and commercial roofs, cleaned via rope access directly at the panel.
Panel-friendly cleaning agents and technique, matched to manufacturer specifications, so that coating and connectors of the panels take no damage.
A short inquiry is enough for an initial assessment.
