Solar pumping systems which pump water from rivers, lakes and reservoirs (but also some wells) use surface pumps which float on the surface of the water or just under it. The water is stored in a tank or can be used directly.
These types of system are usually used to provide water supplies for livestock or irrigation. They are efficient, robust and durable, with very low and easy maintenance. Systems are available in a range of sizes. However, pumps may be subjected to environmental damage (floods, freezing, etc.), theft and vandalism.
Irrigation systems for solar pumps need to be efficient and not waste water. Drip irrigation, which feeds water directly and efficiently to crops, is often used. This is an issue which needs to be considered when a diesel pumping system is being replaced with a solar water pumping system.
