my home roof has become the local spot for doves. My solar panels have crap all over them and have reduce output dramatically.
Any ideas for a permanent fix without resorting to a firearm.
EDIT
Get back up on your roof, insert a small upright bar from steel/aluminium whatever of approx. 6 " in length, make sure you have a hole at the top end. fix two of these at each end of the solar panels the HIGH end, run a wire between these tow uprights, get it as tight as you can without bending or snapping the uprights, tie each end permanently. There you go, anti Dove/pigeon/seagull device fitted at minimal cost.
I'll send the invoice in the mail.
Don't forget, you'll need to do this for each panel.
