The SPIS Web-App

This SPIS Web-App allows for the calculation of pumping head, the pump size in kW and the required solar PV module surface, depending on location, climate, water availability, irrigation layout and water requirements of planned crops and livestock.

The calculations offered here are based on simplified assumptions – the SPIS web app is therefore quick and easy to use. The aim is rather to provide an overview of whether irrigation with the aid of the sun is worthwhile and what the components – the PV-panels and the solar pump – must achieve.

For a detailed calculation, the expert version of the SPIS toolbox can be used, which consists of individual EXCEL files and takes into account considerably more configuration options. However, we expressly point out that the operation of the EXCEL tools requires a certain amount of expertise and is not necessarily suitable for non – experts.

The SPIS Web-App does not indicate prices for pumps or panels nor any brand names, as these vary greatly from country to country – please contact a suitable local supplier or an institution to discuss the conditions of an installation based on the results of the SPIS Web-App.
