User, 17 Oct 2026: "only put solar on the factory, prepare the other
buildings for solar, option a and b should operate on biomass".

- Steam: two 500 kg/h biomass modules (Getabec class, 6M to 10M THB) plus
  a fuel store and handling block (1M to 2M, estimate) in both plans; the
  electric bank becomes the alternative. ~0.67M THB of fuel a year against
  ~4.9M for electric steam; grid demand ~264 kW instead of ~980 kW.
- Solar: ~520 kWp on the factory roof (the biomass-case optimum is ~500 to
  550 kWp, hourly sketch in sustainability.md "PV size with biomass
  steam"); office roof and parking canopies built PV-ready (~120 kWp
  later). ~87 % used on site, ~61 % of the plant's electricity.
- Calculator: biomass default, bFuel row, pvKWp 520, pvSelf 87, iso fills
  the factory roof first and shows the other roofs as PV-ready.
- Numbers: launch plant ~168M / 232M / 296M with contingency; Plan A
  ~182M (~2M above 180M: the Chinese-route lever priced only electric
  boilers; a Chinese biomass quote is the way back), Plan B ~217M (label
  ~215M), ~35M more. Calculator EBITDA A 2.17M, B 2.23M USD.
- CSV, total-investment, revenue-model, sustainability, scale, biomass,
  site-candidates, boi, steam-cooling, construction RFQ (canopies
  PV-ready), README, roadmap; business plan draft 0.3 rebuilt (A and B
  63 pages) with new renders.

The office roof and the parking canopies are built PV-ready. With
biomass the plant's running load falls to ~230 kW, so the best array
is ~500 to 550 kWp ([sustainability](../sustainability.md#pv-size-with-biomass-steam)),
about the ~520 kWp factory roof. Against the earlier electric steam
and ~640 kWp, in Plan B the biomass boilers and fuel store add ~3.8M

~2.8M, so it rises from ~216M to **~217M**; Plan A leases the array and
had the cheaper Chinese electric boilers, so it takes the full ~5.4M,
from ~177M to **~182M**. Biomass saves ~4.2M THB a year of steam energy
