How long does an agricultural solar project take from assessment to commissioning?

An agricultural project typically takes 4–9 months from initial assessment to commissioning, depending on size, grid interconnection requirements, and grant program timing. Grant program cycles are often the longest variable — project milestones are sequenced around them.

Clear answer, explained.

The sequence: 12-month interval data analysis (1–2 weeks), site and structural assessment (2–4 weeks), grant application preparation and submission (varies by program), Hydro One or LDC interconnection application (4–12 weeks), engineering and procurement (4–8 weeks), installation (1–4 weeks), commissioning and ESA inspection (1–2 weeks). Grant program cycles are often the longest variable — we sequence project milestones around them.


Key points

What this means in practice.

  • Agricultural solar projects typically take 4–9 months from initial assessment to commissioning
  • Timeline varies by system size, grid interconnection requirements, and grant program timing
  • Interval data analysis and structural assessment: 3–6 weeks
  • Hydro One or LDC interconnection application: 4–12 weeks
  • Engineering, procurement, and installation: 5–12 weeks
  • Grant program cycles are often the longest variable — project milestones are sequenced around them

When this applies

Best-fit environments.

  • You are planning an agricultural solar project and need to understand the timeline before committing
  • You have a specific deadline — planting season, harvest, farm transition — and need to plan backwards from it
  • You are applying for REAP grant funding and want to understand how the grant cycle affects the overall project timeline
  • You are managing a farm operation and need to understand when installation will occur relative to operational seasons
