Once I mounted my panels on top of my radar arch, I realize that I couldn't
see the sea gull $hit on them and now it's just a routine to check them
every day or so with a wet towel.

My ultimate solution was to add a wind generator to over come this problem
and the lack of sun here in the PAC NW.. Beside out sun angles average to be
too low for efficient solar here..

If you have a specific objective in solar requirements, then the solution
may be to add more solar area.
