Gordon Road is a well-positioned commercial retail site in Johannesburg with consistent daytime trading activity. The property benefits from strong foot traffic and a reliable electricity demand profile that aligns well with solar generation hours.
As an MV-TOU customer, the site operates on a medium-voltage time-of-use tariff, making peak-hour solar displacement particularly valuable. The 285 kWp system is sized to maximise offset during high-tariff periods, delivering strong financial returns.
The large-format retail site provided an ideal rooftop footprint for the installation, enabling a system that meaningfully reduces electricity costs while supporting the property's sustainability objectives.
