Solar (user, 17 Oct 2026: "use as much roof space as possible") - PV on every roof and canopy: ~640 kWp on the Payap scenario plot (factory roof ~523, canopies ~54, flat office roof ~65 kWp around the AC units); ~300 kWp on the Mueang Chi hall. Calculator: pvKWp 640, new pvSelf 85 % (zero export, hourly sketch), PV cost per kWp times the array, office-roof PV in the iso view, roofs drawn full. - 12.8M to 16.6M THB at 20 to 26 THB/W; CSV baseline 34.37M to 56.34M; launch plant ~168M / 231M / 294M THB with contingency; Plan B ~216M (label ~215M), ~39M above Plan A; Plan A unchanged (it leases the array), its solar lever ~17.5M. PV payback ~4.2 to 5.9 years. - Permits (rooftop solar no factory licence since 28 Dec 2024, ERC exemption under 1,000 kVA, PEA zero export) and PPA discounts sourced in sustainability.md. BOI correction - Announcement 3/2568 (in force 1 July 2025) ended BOI promotion for solar installations; only the battery may qualify (12M THB per MW cap). Removed the "BOI solar measure" from boi.md, total-investment, revenue-model, sustainability, site-candidates and both plan versions; Plan B's case for owning the array is the PPA bill it avoids (~0.07M USD a year). Open source (user, 17 Oct 2026) - digital-factory.md "Open source throughout, and working with other plants": everything we run and build is open source on NixOS, our code published (licence to decide), vendor firmware the stated exception; later the stack and factory-automation services for other pressing plants, not in the revenue. - Business plan section 5.6 plus an executive-summary bullet, reading guide and not-modelled mentions; draft 0.3 rebuilt (A 60, B 61 pages), renders re-made with the roofs full.
