Solar Pumping for Water Supply

In many of the places we work, solar pumping is more economical than other power sources. It is particularly good when grid power is unreliable, and where managing diesel generators is a headache. Advantages include that solar pumping can be fully automated; there is no fuel to manage; and it is economical across much of the world.

Solar power is the preferred choice and the first option that all Oxfam projects should consider for off grid pumping.

Solar Pumping for Water Supply - The Book

Oxfam have been part of writing a book, which is a complete reference for solar powered pumping.

This book is based on five years’ work, including visiting over a hundred IDP and refugee camps and communities were visited in 12 different countries, during which hundreds of engineers were trained either in onsite events or via dedicated online training courses.

The book explains in simple and clear language not only the theoretical knowledge needed to understand the technology, but also the practicalities and lessons learnt relating to solar water pumping in humanitarian and development contexts.
