Maintenance Cleaning of Photovoltaic Panels

Once every 4 months or so I venture onto my Roof to clean my photovoltaic panels. All I use is a bucket of water and an extended glass cleaner tool.

Just like I would a large glass window or my car's windshield, the cleaning is easy. There are always some hard grime spots that have to be picked by hand.

Now one of my Panels is clean. I have 8 total and it took me 25 minutes to calmly clean all of them.
