What this assumes
- The split (modules 50%, inverters 12%, structure and civil 25%, EPC services and margin 13%) comes from published 2026 project breakdowns, which agree closely from 1 MW up to 5 MW.
- The four blocks add to 100%, so the margin sits inside the price the client pays rather than on top of it.
- The per-watt range is the published market band for your region and job type. Your own costs will differ.
- This is a planning estimate, not a bid. It carries no land, grid-connection or financing cost.
