How to SIZE YOUR SOLAR PUMPING SYSTEM
Solar water pumps submersible & surface
Solar
water pumping systems have many advantages over
windmill water pumpers. Though the initial cost of solar powered systems
can be similar to that of windmills (however, in many cases far less!),
the lifetime costs are much lower. Windmills must be used where there is a
steady, constant wind for maximum results while solar powered pumps
operate anywhere the sun shines. Solar pumping systems can be installed in
less than a day by an individual or small crew and can be portable, while
windmills (because of the need to erect a tower) can take a larger crew a
much longer time to install. Windmills are secured to the ground and are
stationary. Solar powered water pumping systems are the modern day,
upgraded version of the windmill - using natural resources to deliver
water in off grid locations.
Oksolar has a wide range of water pumping systems for almost every
remote water delivery need.
Pumps and solar electric power systems are available for remote homes,
irrigation, livestock watering,
greenhouses and virtually every pumping need to depths of 1,000 feet
or more. Systems can be custom designed to provide from I- 120 gallons
per minute (gpm) or more with litts ranging from a few feet to:

General Solar Pumping Terms:
Flow Rates: GPD - Gallons per Day (To estimate GPD, multiply GPH
by peak sun hours for location)
GPH - Gallons per Hour (To estimate GPH,multiply GPM by 60
min./hour nGPM - Gallons per Minute)
Pump Performance Vs. Solar Array Output: As voltage varies, flow
rate will vary proportionally
Average stays nearly constant Watts = Volts x Amps
Conversion Factors
Feet of Lift to PSIG - Divide Feet by 2.31
US Gallons to Liters - Multiply Gallons by 3.785
Feet to Meters - Divide Feet by 3.28
Consumption Estimates
People–16-100 GPD per person for all purposes
Large Livestock (horses, cattle) - 13 GPD per animal
Dairy Cattle - 37 GPD per animal
Small Livestock (sheep, hogs, etc.) - 3-7 GPD per animal
50 Chickens - 3 GPD
