The Challenge
Logistics Solutions operated a 200,000 sq ft distribution center with massive energy consumption from 24/7 operations, refrigerated storage, and automated systems. Rising SCE rates and demand charges were significantly impacting operating margins in a competitive industry.
The Solution
Promise Energy maximized the warehouse's expansive roof space with a 2MW solar installation using high-efficiency bifacial panels. The system was designed to handle the facility's complex load profile including cold storage and material handling equipment.
System Specifications
- 4,500 bifacial solar panels (445W each)
- Advanced string inverter system
- Ballasted racking for membrane roof
- Smart load management integration
- Predictive maintenance monitoring
The Results
Reduced energy costs by 62%
Achieved 20% IRR over system lifetime
Added $2.8M to property value
Zero roof penetrations preserved warranty
Completed with zero operational disruption
