This industrial property in Cape Town operates during standard business hours with a consistent energy demand profile. Cape Town's excellent solar resource and the property's favourable roof orientation deliver strong generation performance relative to system size.
Operating on an LV-TOU tariff, the facility benefits from offsetting consumption during peak and standard tariff periods. Despite its smaller scale, the 40 kWp system delivers meaningful cost reductions and a clear return on investment over the project lifetime.
The compact installation was engineered to fit within available roof space while maximising production yield, demonstrating that even modest-sized solar systems deliver compelling economics for South African commercial and industrial properties.
