German International School Cape Town 100% Running on solar energy 2016-11-18

The German International School Cape Town (DSK) in Tamboerskloof has fully embraced a green future by installing a 150kWp solar electricity system, which is designed for embedded generation that will maximise self-consumption and feed excess power back into Cape Town’s electricity grid. This is made possible by making use of the small-scale embedded generation (SSEG) tariff the City of Cape Town offers for solar systems.

Schools are an excellent business case for embedded generation solar systems: During school times most power consumed comes from the solar system (maximised self-consumption) and on weekends and during school holidays the power is sold to the grid.


Over its lifespan of at least 25 years, the solar system will save the school an enormous amount of electricity cost and will set a shining example of the quality and long-lasting performance security of German solar technology. Additionally the photovoltaic system will serve as an early introduction to the opportunities of solar photovoltaic use to the students.” The solar system runs on 442 pieces of SW 340 XL Mono solar panels and could achieve an output of up to 150kWp at any given time of full sun exposure.


Together with the initial off-grid photovoltaic system the school has been using since 2010, this full scale on-grid system that is inaugurated today will enable the learners to have access to this renewable energy technology and compare functionality and production data of both. They will also gather information of financial savings of such an investment into a renewable energy system. This will create awareness and understanding for the vast opportunities for renewable energy in South Africa and Africa.
