A Solar Water Pumping
Comparison
BASIC FACT #1
Any solar panel loses electrical
output when not DIRECTLY
facing the sun.
BASIC FACT #2
DC water pumps produce more
or less water as power is added
or taken away.
For Any Water Pumping

Sunflower Savings per Watering Hole
• 35%-50% in power requirements
– 50 watts - 2,500 watts
• Savings in Solar Costs depend on the current
availability and prices.
– If local costs are $4 per watt:
• $200 - $10,000 Savings in solar panel costs per
Watering Hole
• Additional Cost savings in opportunities to use
smaller, less expensive water pumps

The emPower Plant™ for Solar Water
Pumping
• Submersible water pumps require a base level of
power before they are able to extract water from the
ground. The emPower Plant™ can double the
amount of water pumped verses a fixed-mount solar
array.
• The emPower Plant ™ often allows for smaller sized
submersible pumps to be used due to longer
operational times, further reducing costs.
