Pre-existing Water SourcesWithout Clean Water From Wells, Most People Get Their Water from

Holes in the Ground Shared with Animals

Gasoline Power Water Pumps

• Many wells pumps in the past have been powered by gasoline powered generators

• These require money to buy gasoline, and they are noisy

Solar Power as Solution

• Now solar can power the water pumps, and eliminate the need to purchase fuel to run a generator.

Steps of Installing a Solar Powered Well

#1. drill hole

#2. encase the hole

#3. cleanse well of silt and mud by flushing with high pressure air

#4. form well cap for security

#5. connect hose, wires, & rope to water pump, then lower pump into well

#6. connect pump to water holding tank

#7. install solar array

#8. connect panels to controller to power pump

#9. turn on pump, fill tank, let it flow
