SOLAR PUMPING
Guidelines - Electrical design and installation of solar pumps
In a world where the challenges of greenhouse gas emissions and preservation of the environment are ever more significant,
and in which the challenges of access to water resources require sustainable and efficient solutions, Action Against Hunger
recommends solar pumping approaches to its Water Sanitation and Hygiene (WASH) and Food Security & Livelihoods (FSL)
project managers and project coordinators to consider solar pumping approaches.
Easy to design, environmentally friendly, affordable to invest in and very low cost to operate, solar solutions have many
programmatic advantages, and increasingly attracts actors from the humanitarian world, communities of users as well as
donors.
This guide will help you design your solar pumping projects.
As you go through these guidelines you will learn that it is not necessary to provide too many technical details in quotations.
However, it is necessary to specify the expected outcomes
of your solar pumping system, including:
•
the required quantity of water to be pumped per day,
•
at which height (total head),
•
with the option of connecting
to a power generator,
•
addressing safety with a protective box including fuse, surge arrester, disconnect button, a low level detection probe
inside the borehole, and grounding,
•
With options if applicable (quality of solar panel support,
remote reading of water level, backup power generator …).
Using the simplified calculation formulas (Chapter 2), you will be able to verify the sizing of the system as proposed by the
supplier(s), and ascertain whether the number of panels, the power of the pump and the power of the generator set are
correct.
If you encounter any problems, or if you have not been able to verify the sizing, then request support by sending an email to:
