solar water pump for watering cows.

Lived on farms in my life, especially summers in west Texas and Southern OK. All of them Catle and Horse ranches, and all had water wells and no electricity. Not needed, they use windmills to pump water. -
It sounds like a large dairy operation with a fair amount of power required - why not install 10 or 20KW of solar to off set or support all your operations and run wiring to the pump?Leave a comment:

Why not let the cows walk down to the spring and get the water for themselves?Leave a comment:

1,000 cows x 30 galloner per cow per day = 30,000 gallons of water per day. That number alone is staggering.
I would just drill a well where you need the water and start from there. For a pump that can run all day you need at least 20 gallons per minute (30,000/24/60). For a solar pump it needs to be able to pump it in about 5-8 hours (depends on solar isolation) so you would need at least 60 gpm if you have 8 hours of good solar insolation (most don't).
I was wondering what would be the ideal set up for pumping water up a hill about 500ft of lift and 5000ft of run to a 50000 gallon water tank from a spring to water about 1000 cows? It is currently being done with a generator and a large well pump. The way the system works now is that the generator is on a timer and runs tell the timer runs out then has to be started and reset. So what i was wondering is there any system out there that can handle this large of a demand?(tank needs to be filled every 3 or 4 days) Another thing is there some type of either pressure sensing or wireless float switch that could be at the tank so the system would not have to be started and stopped manually?Leave a comment:

If it runs just when the sun shines, that needs to be pumped in about 5 hours,
for a rate of 3300 gallons per hour, or 55 gallons per minute.
http://www.ext.colostate.edu/pubs/natres/06705.html talks about this kind of system,
and lists several candidate pumps. A couple of them might just barely meet
those requirements. It also says this kind of system isn't cheap.Leave a comment:

500' of lift is a lot for one solar pump. If you could have an intermediate tank at 250', then you could use 2 pumps and do it in 2 stages.Leave a comment:

There are DC water pumps that work directly with solar panels and a controller but I am not sure of their "lift" and distance capabilities to pump as far as you want to.
You might be able to find one that can at least provide some amount of water flow when ever the sun is shining to help top off that 50k water tank but the cost may be much more than installing an automatic generator starting system with a wireless tank level control to run your existing pump.Leave a comment:

Thats a bit of a tuff one to work out, but no doubt it could be done, the whole bit about 500ft lft over 5000ft run makes me think the system would have to be huge.
So we really need to know the specs on the current pump and generator, who many kilowatt hours will need to be produced, if your thinking of a solar solution to this problem. How much fuel do you use a week to run the genny now?Leave a comment:
