Additional information on 1/2 hp Submersible/ Independent of power companies.

At $50 per month or $600 per year over three years the cost of $1700 for the system is covered.   

Over 30 years you would pay power company 18000 dollars.  Initial cost 1800 dollars.  Replacing batteries every three years costs 3000 dollars.  Three pumps over thirty years costs 750 dollars ( likely less).  1000 dollars in misc. repairs every ten years equals 3000 dollars.  Total equals 8550 dollars.  So , a significant savings is possible with this approach.  Of course you will have to check system more often than with power company, but most farmer are checking their cattle periodically anyway.

 No windmills, no cylinder leather problems, no solar pumps requiring periodic filter  cleaning, just a reliable supply of water. Submersible usually last for ten to twenty years. You will not get that reliability from any other approach! 

Basic components: 
1/2 hp pump--115 vac--no control box----$250 
2400 watt, 24 vdc input, 120 vac output-----$600 
2 12 volt deep discharge batteries -----$300 
100 Watt solar panel--24vdc output---- $400 ( see buyers guide on this site) 
Timer ---$100 
Run pump 60 minutes for 400 gallon per day---ten minute segments --6 over day light hours to distribute load on battery. For less water per day, reduce run time accordingly. Pump output 7 gallon per minute. 
For 200 gallon per day, run pump .5 hour. ( six 5 minute segments ) One hour run = 370 watt- hours discharge. 7 hours of solar output at 100 watts = 700 watt-hours input. 

You have the flexibility of running for longer periods by utilizing a 1000 watt ac generator..
