PV Cleaning

Farmer Franz had a PV unit put on his machine shed about six years ago. For the first time it was having a clean carried out by a company. A little bit overdue. One can do it oneself of course but one does need to use treated water without any lime. The company has a trailer with a unit that is connected to the mains and cleans the water befor pumping it to the man wielding the brush.

As can be seen the grey weather continues.
