New Southern Energy designed and a built a 507.43 kWp solar system made up of 1318 x 385 Wp Canadian solar panels and 15 x 27.6k Solar Edge String Inverters. The panels are mounted on the roof of the packing warehouse, and the string inverters were installed inside the building within an identified space on site.
The system connects to the low voltage network of the facility. Additionally, it synchronises with the existing diesel generator supplying the packhouse to offset the fuel consumption. The AC generated power from the inverters are combined in a solar DB which connects to the main low voltage distribution board. This solar system is also grid-tied, meaning that it is connected to the national electricity grid.
The system’s performance is monitored and controlled through a master controller, which can also communicate with the inverters. A Solar Edge plant controller enables the PV system to synchronize with the diesel generator, reducing the fuel consumption during load shedding and power outages. The plant controller does not control the generators separately, but rather as one big generator.
All of the data is logged and saved in cloud-based storage. The monitoring and controlling system also includes a weather station which measures the solar radiation and module temperature. Furthermore, the performance can be monitored in real time via a smart phone app.
