Power Purchase Agreement Options:
Third-party ownership structures enable industrial facilities to adopt solar without capital expenditure through long-term power purchase agreements. These arrangements transfer installation costs and performance risks to specialized solar developers.
Technical Implementation Requirements:
Successful industrial solar deployment demands rigorous attention to engineering and integration considerations.
Structural Capacity Verification:
Industrial roofs must support distributed loads from solar arrays plus wind loading. Professional structural analysis confirms adequacy and identifies necessary reinforcement.
Electrical System Integration:
Large-scale installations require careful electrical design addressing:
- Medium voltage interconnection in many cases
- Transformer capacity and specifications
- Switchgear and protection coordination
- Power quality considerations
- Utility interconnection technical requirements
