Never thought about a storage pond....  not sure how that would work... right now we are re-circulating water at about 3500 gph... and I don't think that the flow is really enough.  Seems like you'd need a big pond to feed that volume of water...  and you still need to pump it back into the storage pond.?

#2 -  Renewable Energy > Technical Discussion: Solar Water Pumping > Pond Water Fall Pump
Hello, we have a couple of ponds that have 2500, and 3500 gph waterfall pumps.  We also have a full solar array on the roof.. but it still doesn't fully cover all our electric.  The fellow that came out to service our solar inverter recently suggested putting dc pumps on the ponds that are directly powered from separate solar panels.  That way we wouldn't need inverters, batteries etc. We'd not be looking to replace the existing AC pumps, but instead to plumb the DC pump in parallel, and it would only run when there was enough sun. At other times, the AC pump would be in service.. There is already a timer on the AC pump, so could just set it to turn off/on during the day when the DC pump is running etc.  I've seen some dc bilge pumps that might work, one draws 15.5 amps at 12v DC.   Is this feasible, and how big a solar panel(s) would we need to run the pump?    Thanks in advance for any assistance.  -cjr-

Hello, we have two ponds with waterfalls, one of which pumps about 2000 gallons per  hour and is 1/3HP.  We have another smaller pond..I don't have the details on that pump.  We have been told that the pond pumps, which run 24/7/365 account for about 1/3 of our electric bill which runs about 1000kwh/mo.  We have looked into full solar systems for the house, but I am wondering if there is a way to do a small solar system for the big pond, and then buy a solar powered pump system for the smaller pond,and have a better cost/benefit.  We'd have to have storage because the pond pumps really need to run 24 hrs.  We are on 2.5 acres, w/great open exposures, so it would be easy to install a small system.  Thoughts?  Thanks..
