By self maintaining, I meant that you would not go to your pond for long periods and would want to assure that the aerator keeps running.That's where it can get really expensive. Also, long aeration times, especially during the day while battery is needing to charge.
Some people dont realize just how expensive solar or wind power is as compared to electrical grid. Grid power @ 10 cents per Kilowatt hr. means 100 watts is 1 cent. 100 watts of solar power is $500 dollars or more. That's 50,000 times more. All I'm saying is I am trying to squeeze the most out of a system, by lowest wattage pump to do the work required, which is overcome 8 ft. of water weight to force out bubbles. Deeper ponds, longer run times, etc. push the cost up dramatically.
If you will change out the battery every 2 wks. or so, aerate 6-8 hrs. daily we can come up with a good system, reasonable price.
I will give you and meadowlark a materials list this weekend by PM.
