I'm no expert on anything regarding ponds, so just a suggestion here.

When you put in your system, you may want to consider having it run thru a battery bank. If the situation should ever arise where your surface temps start getting too warm, you may need to run the system during predawn hours, which is when your DO will be at its lowest. You cant do that if you're running straight off the panels, since you need the sun to run. Batteries give you more flexibility to when you NEED to be aerating.

I've already adjusted run times to early daylight hours because temps were crowding 80f on top and we're no where near the dog days of summer yet.
