1.27 MW rooftop solar for a grocery distribution facility in Mississauga, Ontario
Rabba Fine Foods partnered with Green Integrations to install a 1.27 MW rooftop solar system at its grocery distribution facility in Mississauga, Ontario. The system generates approximately 1.41 GWh of solar electricity annually and offsets 67.2% of facility electricity consumption while supporting long-term operational efficiency.
A high daytime load against a roof asset approaching the end of its replacement cycle.
Grocery distribution facilities operate with sustained, high electricity demand driven by refrigeration systems, material handling equipment, and extended operating hours and play a critical role within the broader food and beverage industry. Reliability is critical, as these facilities support time-sensitive retail supply chains where downtime is not an option.
At the Coopers Drive distribution centre, Rabba Fine Foods sought to reduce long-term exposure to grid electricity costs while maintaining uninterrupted warehouse operations. Any solution needed to integrate into an active logistics environment, preserve operational reliability, and deliver measurable outcomes without disrupting daily throughput.
Size to the service. Mount without penetrations.
A large-scale rooftop solar system was engineered to offset a significant portion of the facility’s annual electricity consumption while remaining fully grid-connected. The system was sized to the facility’s annual consumption profile, with electrical integration coordinated around existing infrastructure to ensure consistent performance and long-term reliability.
By generating electricity on-site, the distribution centre reduces dependence on grid-supplied power while maintaining full operational continuity. The project delivers a durable on-site electricity source that supports cost stability and emissions reduction across Rabba Fine Foods’ retail supply chain.
The numbers, then the consequence.
- 011,412,187 kWh of solar electricity generated annually.
- 0267.2% of the facility's annual electricity consumption offset by solar.
- 031.27 MW DC — the largest single rooftop solar installation in the Green Integrations portfolio.
- 04System commissioned August 15, 2025, integrated without disruption to distribution operations.
Equivalent to removing 19 passenger vehicles from Ontario roads annually.
For the facilities and engineering audience.
The system consists of 1,271 kW DC (2,374 × CSI Solar 535W panels) paired with 960 kW AC via 40 × Fronius USA Symo 24kW inverters. TerraGen racking was used throughout. The system was designed for a continuously operating grocery distribution facility serving the food and beverage sector.
Electrical integration and system capacity were coordinated with existing infrastructure to minimise disruption and ensure safe, reliable operation in a high-load warehouse environment.
Facility characteristics that shaped the design.
- Large grocery distribution facility supporting regional retail operations
- Sustained annual electricity demand driven by refrigeration and material handling
- Expansive rooftop area suitable for large-scale solar deployment
- Predictable annual load profile enabling accurate system sizing and performance planning
