The world’s most economical solar pumps that lifts from as deep as 650 feet (200m) with a maximum of 16,000 gallons per day(60 cu.m.) ETAPUMP eliminates the costs of fuel delivery, engine maintenance, and pollution. In many cases it is LESS COSTLY than a conventional pump and generator installation!

• Great reliability and life expectancy

• Only one moving part, brushless motor

• High resistance to sand and corrosion

• Fits 4" and larger well casings

ETA is a Greek letter that engineers use to represent. ENERGY EFFICIENCY. In solar pumping, HIGH ETA = LOW SYSTEM COST. ETAPUMP uses a solar array of 20-50% less power than other solar pumps to do the same work. It is the most economical solar submersible pump available today.

ETAPUMP has only one moving part —no failure-prone diaphragms or motor brushes to replace. ALL electronic control parts are above ground for easy access and greatest reliability. Be cautious of solar pumps with controls sealed inside the motor—if one tiny part fails, the pump must be pulled and the whole motor replaced.

ETA PUMP INTEGRATED SYSTEM ™ is complete and ready to install

An ETAPUMP INTEGRATED SYSTEM is a complete system kit, engineered for the lift and daily volume that you require. It includes premium crystalline UL-listed solar modules (panels) with a life expectancy beyond 30 years. The fixed solar array rack is engineered for 90 MPH (145 km/h) wind, tracked rack is for 75 (120 km/h) The controller is weather-sealed for all climates.

Install the pump by the same methods and materials used for conventional submersible pumps. The solar array requires nuts-and-bolts assembly and standard wiring practice. The ETAPUMP instruction manual is clearly illustrated. No special product training is required. ETAPUMP INTEGRATED SYSTEM™ Components vary according to the system number

• Pump and controller • Solar modules (panels)

• Solar array mounting rack (top-of-pole)

• Junction box with internal PV disconnect switch

• Wiring harness & flex conduit, j-box to controller

• Submersible cable splice kit • Low-water probe

• Detailed, illustrated instruction manual

THE FOLLOWING ITEMS ARE NOT INCLUDED.

They are available from local suppliers.

• Steel pole and concrete to support the solar array (schedule 40 pipe, size and length specified in the rack instructions)

• Drop pipe (refer to a pipe sizing chart) Submersible pump cable, 3-wire + ground

• Water well safety rope (1/4")

• Wire and standard electrical hardware

USING THE TABLES BELOW                                                                                                It looks more complicated than it is so follow these guidelines and you should be able to find the correct system at the most reasonable cost. You must know the depth and volume of water in Gallons Per Minute (GPM) of your well.

1. Starting at the top of the table, use the "Vertical Lift in Feet" column to find a pump that is capable of pumping at the depth of your well.

2. Move right, to the "Gallons Per Minute" column to see if that pump is at, or just below the capabilities of your well.

3. Moving to the right one more time shows us how many "Gallons Per Day" (GPD) you can expect from a location that has 4.5 Peak Sun Hours "PSH" on a fixed solar array when it's angle is fixed the same as your latitude. One more column to the right shows you how many GPD you can expect if the solar array follows the sun "Tracked"

4. If you need more water just keep moving down the tables until you find one that matches your well.

If it all seems too overwhelming just e-mail rob@nwes.com with: Your Location, the depth of your well, and volume (Gallons Per Minute) of your well.

The gray cells in the table below tell us the following:

1. The ETA-04-090 set 25' deep will pump 2.6 Gallons Per Minute (GPM) and cost $2710.00

2. It will pump 720 "Gallons Per Day" in a location that has 4.5 "Peak Sun Hours" with a fixed array, or 970 GPD if the solar array follows the sun "Tracked"

3. Or it will pump 1040 "Gallons Per Day" in a location that has 6.0 "Peak Sun Hours" with a fixed array, or 1510 GPD if the solar array follows the sun "Tracked"

4. It will pump 1270 "Gallons Per Day" in a location that has 7.5 "Peak Sun Hours" with a fixed array, or 1920 GPD if the solar array follows the sun "Tracked"
