5 Star TRF1 Business Park is a commercial business park in Johannesburg accommodating office and light industrial tenants. The property's mixed tenant base generates a consistent electricity demand profile throughout business hours.
Operating on a low-voltage time-of-use (LV-TOU) tariff, the property benefits from solar generation displacing grid electricity during peak tariff periods. The 124 kWp system is well-matched to the park's daytime consumption patterns.
The rooftop installation delivers meaningful savings across the business park while reducing the property's carbon footprint and supporting tenants' sustainability reporting requirements.
