Kärcher's RM 99 tackles solar panel cleaning14th of March 2013
New from Kärcher is a cleaning agent for solar panels for use with a high pressure cleaner, RM 99. The efficiency of panels can be reduced by up to 20 per cent by pollen, bird droppings and dirt from emissions says the company.
The new detergent cleans panels and dries them after rinsing without leaving streaks so fresh dirt takes longer to settle. It is slightly alkaline and biodegradable so can safely be discharged into the drainage system.
One litre of RM 99 concentrate is enough to clean 500 square metres.
