Canero Office Park is a commercial property in Johannesburg hosting office-based tenants with consistent daytime energy consumption. The building's standard operating hours and reliable electricity demand profile create an excellent match for solar energy generation.
The facility operates on an LV-TOU tariff, with electricity costs peaking during morning and afternoon periods when solar generation is at its highest. This natural alignment between production and consumption ensures that a significant portion of generated energy directly offsets the most expensive grid electricity.
The 124 kWp rooftop installation was carefully designed around the building's structural capacity and available roof space, delivering a clean, integrated solution with minimal visual impact and maximum energy yield.
