Clear answer
Clear answer, explained.
System size is primarily limited by usable roof space, structural load capacity, utility interconnection limits, and the facility’s daytime energy demand. Many projects fall in the 500 kW to 5 MW range, with some sites supporting even larger capacities.
Key points
What this means in practice.
- Typical range: 500 kW to multi-MW Roof area and structural capacity set the physical limit
- Electrical service size and interconnection rules affect maximum capacity
- Daytime load profile influences optimal system sizing
- Larger systems benefit from lower cost per watt
- Final size is confirmed through engineering and utility studies
When this applies
Best-fit environments.
- Large warehouses, manufacturing plants, and logistics centres
- Facilities with high and consistent daytime electricity use
- Buildings with large, unobstructed roof areas
- Projects evaluating rooftop versus ground-mount or carport options
