Solar Water Pump Sizing Questionnaire

What will the water be used for?*

Home
Irrigation
Livestock
Other

If other, please describe:

What are you daily water requirements?*

gallons per day
liters per day

Will the water system be used year round?*

yes
Just Summer
Just Winter
Other

If other, please describe:

Is there another source of water besides the solar pump?*

yes
no

If yes, please describe:

and what percentage of your need must be met by solar?

What is the distance between the pump and the closest location where solar panels can be located without being shaded?*

Feet
Meters

1. Well depth?

Feet
Meters

2. Depth to water?

Feet
Meters

3. Recovery rate? (in other words, what is the rate at which the water in the well is replenished?)

gallons
liters

minute
hour
day

4. Well casing diameter (if it’s a drilled well)?

inches
centimeters

1. Describe the source of the water (e.g. lake, stream, water tank, etc)

2. What is the vertical distance (not horizontal) from the surface of the water source to where the water needs to go?

Feet
Meters

3. How close can you install the pump to the water source?
Note: Pumps can only suck water up 10-20 feet maximum, so the closer to the water source the better.

Feet
Meters

1. Length of pipe required (distance from well to storage tank)?

Feet
Meters

2. Diameter of pipe installed or planned?

inches
centimeters

Do you need the water to be pressurized?*:

Well pump will supply pressure
Separate Pressure Pump
Unpressurized System
No pressure needed

If you need the pump to provide pressure, how much pressure do you need?
PSI (Note: average home water pressure is 35-40 PSI)

1. Is there a working pump already in place?

yes
no

2. If yes, please describe the pump and power source:
i.e.: horsepower/watts, voltage in AC/DC, flow rate in gallons/liters per minute.

Household	10-50 gallons (40-200 liters) per day per person
Cattle & Horses	10-30 gallons per day in dry weather per cow/horse.
Small Animals	1/4 gallons per day per 25 lbs of body weight (1 liter per 10kg)
Poultry	6-12 gallons (20-45 liters) per day per hundred birds
Young Trees	15 gallons (55 liters) per day in dry weather
