About two years ago, the V&A Waterfront commissioned 4,207 solar panels (7,000m²) installed on the roofs of the main Waterfront buildings, with a total electrical output of 1,093.8 kWp at a cost of R20 million. It conserves about 1,721,956 kWh annually, significantly reducing the Waterfront’s environmental footprint. At the same time, Boschendal commissioned its first, small rooftop solar installation at the Rachelsfontein complex.
Then in October 2017, Robben Island launched its R25 million, 666kWp solar farm supported by 828 kWh battery storage, to reduce reliance of diesel which was shipped in for the island’s generators. Just based on the cost of fuel savings, the Robben Island installation will pay for itself within five years. The micro-grid on Robben Island is the largest combined solar and lithium-ion storage micro-grid system in South Africa.
