Meadowbrook Office Park is a dedicated office property in Johannesburg operating on standard business hours. The predictable weekday electricity demand profile aligns well with solar generation, making the case for solar PV particularly strong.
Operating on a low-voltage time-of-use (LV-TOU) tariff, the property benefits from solar generation displacing costly grid electricity during the morning and afternoon peak periods that coincide with office occupancy hours.
The 50 kWp rooftop system delivers reliable and predictable electricity cost reductions, supporting the property owner's objective of improving operating efficiency and reducing the building's carbon footprint.
