Toolbox on SPIS
Introduction
Most water pumps utilized for irrigation purposes worldwide are powered by engines run on fossil fuels (diesel, petrol, gas) or on electricity supplied from the grid. Fossil energy sources are limited and emissions from their utilization have negative climate impacts. At the same time, the electricity supply in many developing countries is often insufficient and unreliable or wholly absent in rural areas. Moreover, prices of solar panels have reduced while the quality has improved. Today, solar pumps for irrigation have become an economical, technical and environmentally viable alternative to conventional pumping systems. read more
However, major hindrance for the uptake of the technology is still a lack of information on solar pumps for irrigation and its relatively high investment costs. The knowledge on the potentials, limitations and risks of Solar-Powered Irrigation Systems (SPIS) is incomplete among policy makers, producers and other stakeholders. For example, SPIS are seldom designed in a way that producer needs and site specific conditions (environmental, agronomic and technical aspects) are comprehensively addressed. Consequently, the potential of the technology is not optimized, or worse, has negative ecological and economic impacts.
This manual provides up-to-date information on the technology and methods of promotion, as well as how to finance SPIS. Furthermore it gives insight into how SPIS are designed, set up and maintained. It is accompanied by a set of tools, such as maintenance checklists, data collection guidelines and design calculations. It strives to help find the optimal design of a system, thereby avoiding risks related to system efficiency, financial viability and the unsustainable use of water resources. The manual and tools target stakeholders who advise or finance medium-sized agricultural enterprises. These are agricultural (irrigation) extension advisors and credit officers / risk managers in financing institutions. Furthermore the manual support the advisory function of SPIS suppliers, by providing them with a holistic set of knowledge through which they can guide their clients towards a financially and environmentally sound decision.
The manual follows the course of action involved when giving advice on SPIS for an agricultural enterprise. It consists of this introduction and seven further modules. The modular approach enables the user to pick out specific information relevant to his/her situation. Each module however relates to and supplements the other modules.
- GET INFORMED specifies the components and common configurations of a SPIS. Each component is described in detail.
- PROMOTE & INITIATE provides important information and tips for someone who wants to promote the SPIS technology in a particular area. It focuses on the analysis of opportunities and risks, the stakeholders involved, as well as promotion strategies and activities.
- SAFEGUARD WATER focuses on water governance issues and potential negative impacts of (ground-)water depletion through solar pumping.
- FINANCE provides information to financial service providers financing or planning to finance SPIS. The module targets stakeholders at management level who decide on credit policies and loan officers who assess single loan applications for financing SPIS.
- DESIGN helps to select the suitable system configuration for a specific situation. A substantial set of tools helps to assess site conditions, select and design the appropriate type of SPIS and conduct a simplified financial viability assessment and calculates the detailed financial viability of the producer.
- SET UP provides information and tools to enable the installation of a SPIS. It focuses on the selection of installers, acceptance and system tests as well as documentation and hand over of the system.
- MAINTAIN elaborates on maintenance plans, the selection of service providers, regular routines and documentation and monitoring.
Module Structure
The modules are all structured uniformly. It starts with the module aim and orientation and a brief description of the relevant process steps. These are processes that are recommended to be considered in a particular order. They are numbered and summarized in a flow diagram at the beginning of each module for easy reference read more
Structure of Each Process Step
Each step in the process of each module is described on one or two pages. The process step is concluded with an overview of the most relevant aspects:
- Outcome / products
- Data requirements;
- People and stakeholders involved;
- Important issues to be considered.
At the end of each module links for further readings and multimedia files are provided. This last page is also used to describe what tools supplement to the module. The tools are available online and users can adapt them to their specific needs.

The Toolbox for SPIS Advisors is made possible through the global initiative Powering Agriculture: An Energy Grand Challenge for Development (PAEGC). In 2012, the United States Agency for International Development (USAID), the Swedish International Development Cooperation Agency (Sida), the German Federal Ministry for Economic Cooperation and Development (BMZ), Duke Energy, and the Overseas Private Investment Cooperation (OPIC) combined resources to create the PAEGC initiative. The objective of PAEGC is to support new and sustainable approaches to accelerate the development and deployment of clean energy solutions for increasing agriculture productivity and/or value for farmers and agribusinesses in developing countries and emerging regions that lack access to reliable, affordable clean energy.
