SOLAR WATER PUMPING |

|
|||||||
For
livestock producers and many other applications, "solar" and
"water pumping" go along together as well as pigs in
mud! If you have
a well you're not using, and need to expand your pasture's horizons,
call us with your well specifications, as well as the number of cow-calf
pairs you're watering. We'll let you know what it will take to
keep your thirsty cows happy. If you have need of a residential
water system, let us know what kind of pump you have in place now, how
much water it pumps in terms of gallons-per-minute, and the amount of
water you need on a daily or weekly basis. |

Check the insolation map to determine the amount of water this system will supply in an average day, and in what zone: |

(*gallons per day--and these figures tend to be conservative) This Shurflo model will pump from a maximum depth of 230 ft. in a minimum of 4" casing. At that depth you'd need two 75W modules (with an additional cost of $160) instead of 60W modules. Remember, the above figures reflect averages; you will get more water in summer--perhaps 25% more (in times of higher livestock and garden demands) and less in winter. This system is meant to pump into a holding tank or cistern, and will not provide for a pressurized system by itself. For additional information on the Shurflo Series 9300 Sub Pump, click here! |

We will assume (for example) you're powering a 3/4 HP pump for one hour daily, for this system's load requirements. A pump that size draws 1325 watts per hour--or 1660 watt-hours adjusted for the load correction factor. Since the starting surge can be 3 to 5 times the load current, it'll take a sizable inverter to cover the surge...fortunately, Trace Engineering makes a remarkable transformer (their T-240) that'll handle most motor loads up to 1 1/2 HP, and that fact keeps us from having to "stack" two 110 AC inverters to receive our 230 VAC output. We will assume that the average daily insolation (amount of full sun) is 4 hours per day where this site is. Here's how the system breaks down:
