Q: What is a submersible Vs Surface solar water pump?
A: The difference between these two types of pumps is in the names (among many other things). A submersible water pump is one that needs to be underwater at all times to function. These are best used in boreholes and wells. They tend to be more expensive to install and maintain.
On the other hand, a surface solar water pump is one that stays above water. It’s best used where the water table is within a depth of 10 meters. These pumps are easier to install and maintain compared to the submersible types. Pipes are attached to the pump to bring water from the water source and take it to where it needs to go.
