wind and solar

[skipper]

I need a wind and solar system to run a pump to pump water at 100-200 feet for livestock about 5 to 10 gpm

That is a fair amount of water flow...

• Are you looking for 3,000 gallons per day?
• Seasonal (less in winter, more in summer)?
• Do you have problems with sand in the well water (hard on pumps)?
• Do you have a cistern to store water for cloudy days or do you need backup power?
• Can you live with pumping only when the sun is up and shining?
• Does the system need to be fully automatic or can you fire up a genset when needed?
• Do you have an existing pump in well you need to run or are you planning on a new pump setup?
• What are the prevailing winds in your area? By season?

For Bismark North Dakota, you have this much sun per month:

According to this chart (PDF) for Grundos in well pump with 200 foot head and > 3,000 gallons per day at 6+ kWH per m2 (~summer months using above data) and 1,200 watts of solar panels (no battery system--recommended for lower initial costs and no battery replacements required over time)...

I am no well/pump expert, but that is where I would start.

Does anyone have a wind turbine based pump in your area? Is there a good source for parts and maintenance?

I dont think you can use a wind genny connected straight to a pump far to variable the voltage.

I was going to jump in, but man, this thread is all over the place. And what if you were only kidding? Part of it was serious, right?

Your posts are something else.. but exactly what I have no idea..
No post you write makes any sense whatsoever.?
Have you recently been released from some nice resting place??

Somebody from India, using a picture from the web of several students from Penn State with the owner of the pictures appearing to be out of Egypt. I have deleted the posts, banned the user, and blocked the IP address.

Don't know what the point was--but it seemed that the poster was getting ready to start posting commercial spam (nothing on web other than the IP address was a bit suspect).

I would get a good solar pump and forget the wind.
It's easy to come up with 5 gallon a minute at that depth if the supply is at the well or close and you have enough storage.
Easier to store water than pump it so consider a larger tank if needed.
I like "tire tanks" for storage as they very seldom need additional heat for winter use, I let my pumps run all year and the warm water will thaw the ice that accumulates so they stay open if the sun shines. I have the overflow away from the tanks so ice isn't a problem around the tanks.
