Solar Well Pumping; Info on solar well pumps

So I was looking at http://www.jtechsolar.com/wellpumping and thought I would share some info on solar well pumps.

The options for deep well pumping has increased in the past years and Grundfos has made a solar well pump which is the most versitile pump on the market. It can pump from depths of 300' and can still produce a decent amount of water 3-6 GPM, they can also pump in the upper ranges of 11-16 GPM and still build pressure as good as conventional pumps can.

The advantages of these pumps?? they can run on 30-300 VDC or 90-240 VAC, They can be powered by utility, solar, electric wind turbines and hydro electric turbines. One other good feature they have is that they use a softstart technology that reduces startup surge like traditional AC pumps. You can actually run these pumps off of a 1500 watt AC 120volt generator, most conventional pumps require a 3500watt or larger 240volt AC generator that also needs a startup capacitor inline of in.

feel free to ask any questions that you may have.

How about an old fashioned Texas Windmill? A lot of folks out here still use them.

At our old place we had a 600' well with a 220v ac pump.
I would have much prefered a DC pump so we could have had a battery back up withsolar charging.

One solution if you have low volume output would be to install a storage tank above the point where you need the water and use gravity to provide the needed pressure. It doesnt take much height to create the head pressure you need. This would also give you the advantage of having an extra reserve of water. Rusty is right, windmills are used a lot out on the ranches here in West Texas. The volume is not that great but it pumps continuously to storage tanks usually ontop of a hill. Then poly lines are ran to troughs for livestock sometimes miles from the storage tanks.

I have done quite a few water systems and I would like to have one of the old windmill types, here in n.california is that the wind does not always blow but the sun is usually shining. The thing that is prime about the pump that I use is its versatility on what can power it,

i have a question and some statements.
I have a ranch in South Texas. Been in the family since late 50's
it has one well on it that I drilled in 2006.
This well is right next to a hand dug well from the late 1800's (flood caved it in about 2002)
This hand dug well had a windmill on it.... still does but not operational at this time.
There is a storage tank about 30,000 gallons right next to the windmill.

The well I dug in 2006..has a 220v submersible pump on it
The water line is at 30'
The pump is set at 50' so it has cool water to cool it.
Well is total 75' deep.

i would love to put on a solar powered pump.
and also have gravity from the storage tank (it's about 20 feet tall - 8 feet in diameter)

Should anything happen...
i would like to have my family situated with ... Water .... Food.... Protection
if anything happens.... i bet the electric will be cut off and there goes the water.

what would it cost to put in a solar powered pump these days ???

any info would be appreciated...
