I have a 1/3 acre pond that is approx. 2 feet deep that I use for duck hunting. I have no power on the property. I am leaning towards a home made solar system. I can dig the pond deeper if it would help my situation. Need to run the system only during hunting season (Nov. and Dec.) for close to 24 hours/day to keep from freezing. Can some help me out with a efficient cost effective system. thanks Damon
