- Toolbox for beginners,
- Toolbox for farmers (new SPIS Web based App – to calculate design of the pumps),
- the Toolbox for experts - the updated version - Version 6
and additional resources (Publication about SPIS).
The Toolbox on Solar Powered Irrigation Systems (SPIS) is designed to enable advisors, service providers and practitioners in the field of solar irrigation to provide broad hands-on guidance to end-users, policy-makers and financiers. Risks related to system efficiency, financial viability and the unsustainable use of water resources can thus be minimized. The Toolbox comprises informative modules supplemented with user-friendly software tools (calculations sheets, checklists, guidelines). read more
