As with wind powered systems, it is important to have adequate tank storage to carry through periods of low sunlight levels and heavy water use. Figure 10.11 illustrates low voltage DC solar powered pump systems using a submersible pump in a well and a rotary vane type pump from a spring box. A tracking type solar panel allows greater power gain throughout the day. These are simple systems without batteries or converters. Figure 10.12 illustrates a pump jack system. This works in deeper wells and is ideal for replacing windmill systems. The pump will pump water even under low light conditions, although pumping will be slower. There are several different types of pump systems on the market. Each has particular advantages. Design must be done in close coordination with pump and solar panel suppliers. Figure 10.11 TYPICAL SOLAR SUBMERSIBLE PUMP GRAVITY SYSTEM Figure 10.12 Powered Pump Jack 10.1.8 Internal Combustion Engine Powered Pumps Internal combustion engines can be used to operate stockwater pumps. These engines are sometimes started with a float operated automatic starter and shutoff switches. They frequently use propane as a fuel. Engine operated systems require frequent monitoring. A water storage tank should be part of the system to supplement times when the system fails or is not started on time. are various ways that such a system can be set up. They include: 1. An engine operated pump jack operated by gas or propane motor. Water is pumped into a large storage tank. The motor is started by hand. It can be shut off with simple grounding type float switch or when it simply runs out of gas. Sometimes an automatic starting system is used. 2. An engine operated generator which in turn operates any type of electrically driven pump system. This type of system either be automatically started and stopped with a float switch or manually started and shut off by a float actuated switch in the storage tank.
