Submersible solar well pumps

I am looking to buy a submersible solar well pump. Does anyone have any recommendations? I have been looking at the shurflo 9300, the aquatec SWP 4000 , the sunpump SDS series and the NASS 4 by North American Solar Solutions. It is hard to make any decision because there is very little discussion about these products and companies out there. Thanks!

Hey Joe-

I've recently put in a well at our new place. I wanted to have the water system on a separate power system from the house. We ended up with a Grundfos SQFlex pump, a 380W solar array, and a 48V 130AH battery. So far the system has been functioning outstanding! and through the toughest time of the year, a VT winter. We've had plenty of power for the pump and haven't needed to think about rationing water at all (from a power consumption point of view).  We choose that pump based on a few recommendations and the low startup amperage, although it was a bit on the pricey side, hopefully we won't have to replace it for sometime.

A couple things to look into while selecting your pump.  The wire that you need to run the pump gets big and expensive quickly. We needed 150' of #6 wire to the pump. So depending on the depth your pumps need to be in your well and the distance from the power system... it can add up quick.  

Also make sure that the pump has the head requirements for your situation, don't forget the head required for what pressure you need.

Hi.... we too have a Grundfos SQflex pump..... they come custom set up for your needs... depending on how high you need to lift the water from the level in the well to point of use.... and how many gallons a minute you can or need to pump from that well..... our well is 100 ft deep and can put out 50+ gallons a minute.... we bought a grundfos pump that pumps 25 gallons a minute... and lifts the water 185 ft....... to a 3,000 gallon storage tank on a hill...... and from there is gravity feed to our house, barn, greenhouse and gardens..... we only need to run it for about 3 hours to fill the tank and then it lasts for weeks, ..... this system needs no batteries  (because we turn it on when the sun is shining)....... these pumps run on direct sunlight DC or AC...... they have a low power shut off and a too much power and run dry shut off, to protect the motor.... we feel they are the very best well pump for solar application... price around $2,000

We are currently 'all electric' but wanting info on a solar pump.  I'm totally new at solar.  Currently, the 1 gallon pressure tank isn't working, so the pump is turning on everytime we run water.  This will be our first summer on this property.  I'm concerned we are going to have a HUGE electric bill due to running the pump so much now that we are watering trees, berries, grass, etc.  

Can you share any other information that might help me?  I don't even know the questions to start asking or who to ask.
