Seems like the system should work well for any size pond if the intention is to simply keep a hole open in the ice along one edge of the pond. Most recommendations I have heard on this forum for winter operation is to place the diffuser shallow (4' or so to keep from super cooling the BOW). So from that respect it would not matter the depth of the pond.
Thanks for the update. I may get interested in solar aeration some day as my old pond could use it. But it will be for summer use in a different type of application. But what you have learned and shared here on the forum can still be useful information should I decide to try it.
