Solar pumping systems which pump water from deep wells or boreholes use submersible pumps which are installed in the well or borehole. They are efficient, robust and durable, and require very low maintenance.
These types of system are usually used to provide water for human consumption or water supplies for livestock. Pumped water can also be used for irrigation, depending on water requirements and the value of the crops.

Most of the work and cost will be drilling and preparing the well or borehole (if it does not already exist). Knowledge of hydrology is required when designing and sizing solar pumping systems for large borehole pumps, so it is recommended to purchase systems from companies which specialise in this field.
