When comparing both the gravity driven and pump driven set ups, illustrated in Figure 1, it can be observed that the pump in the gravity driven system will require more power to run compared to the two pumps of the pump driven set up, since it will have to empty and elevate the water. Therefore, the power requirements for the gravity driven set up were calculated first to size the pump, battery, and solar panel needed. The power requirements of the pump driven set up were solved to assure the selected battery and solar panel would satisfy its requirements.
