ILRI, 12th April 2012
The Sunflower Pump
What is the Sunflower pump?
•
•
•
•
•
•
•
Solar thermal household water pump
Designed for irrigation
Allows dry season cultivation of cash crops
Ground water depth range < 15m
Suction pumping also possible
Add-on – battery, mobile charge?
Target cost 4500 – 6000 Birr
Pump in Operation

Design criteria
•
•
•
•
•
•
Low capital cost
Negligible running costs,
High daily water yield
Hard wearing
Manual back-up
Simple components to maximise local manufacturing
and assembly
• VLOM (like a bicycle)
Key Benefits
• Create income generating opportunities for poor
small holder farmers
• Improve food security during dry seasons (climate
change adaptation)
• Free children and women from the onerous task of
lifting water
• Provide an alternative to polluting, expensive fossil
fuel pumps
• Catalyse creation of small businesses in
manufacturing, assembly, repairs, sales etc.
• Provide other rural power requirements
Team
International
• Sunflower.org (UK) – company dedicated to commercialisation
of solar steam pump
• Practica Foundation (Holland) – appropriate technology
research and development NGO
• IDE (Ethiopia & US) – NGO focused on ‘creating income
generating opportunities for rural poor’
Local
• Manufacturing Partners – to manufacturer, assemble, install ,
post-sales service.
• Local Facilitating Partners – promotion, training, quality
control, maintenance i.e. Technology Support
Development timeline
Funding secured
Not funded
• 1980s - 2009 experimentation and testing of early
prototypes
• 2009 – working prototype that satisfies all design criteria
• 2010 – initial field testing in Ziway, Oromia
• 2011 – design and testing of improved prototype in
Netherlands; market and manufacturing study in Ethiopia
• 2012 – further supply chain research, trial manufacturing
and assembly of 10 – 20 units in Addis/Bahir Dar;
extended field testing/pilot installations around Ethiopia.
• 2013 – manufacturing blueprint; selection of local
partners; volume production; development and training
of support services, marketing and sales
Funding
• Liberty Foundation – 150, 000 Euros
– R&D
– Market study
– Local manufacturing study
– Ten improved prototypes in field
• REEEP/IDE – 150, 000 Euros
– Supply chain study
– Financing mechanisms
– Local v global production study
– Design optimisation for mass production
– Development of training materials
