End of Project:
Irrigation systems are the largest single energy consumers on commercial farms in Africa. Photovoltaic know-how in Africa has thus far been limited, mainly to smaller off-grid systems, or several MW large grid-connected PV systems that feed all the generated electricity into the grid. With the help of ewz’s know-how, Mount Sunzu Switzerland Ltd. aims to supply most of the electricity for the new irrigation system it is building on its own coffee farm by using PV power. Since this means that the energy supply is subject to much greater fluctuations, the irrigation system itself also needs some optimisation in order to be able to irrigate sufficiently at all times. In addition to the actual PV system, an intelligent control system is also required.
It is planned to operate the Mount Sunzu Farm’s new irrigation system for its coffee fields with PV electricity for the most part within this project’s framework. So far, mainly diesel generators have been used in northern Zambia, due to the unreliable electricity grid. The project team is trying to replace these completely. A 90 kW PV system is to be built for this purpose which will be connected to the power grid and together with it, provides the necessary drive energy for the entire irrigation system.
