Clear answer
Clear answer, explained.
Large systems often require detailed grid impact and protection studies, which can extend approval timelines. Onsite installation usually takes several weeks to a few months, while the full process from design to commissioning commonly spans half a year or more.
Key points
What this means in practice.
- Typical total timeline: 6–12 months
- Engineering and permitting: several weeks to months
- Utility interconnection and grid studies: major schedule driver
- Equipment procurement can affect lead times
- Onsite installation: weeks to a few months
- Final commissioning follows inspections and utility approval
When this applies
Best-fit environments.
- Industrial rooftop systems in the 1
- MW to multi-MW range
- Warehouses, factories, and large logistics facilities
- Projects requiring detailed structural and grid studies
