      "reason_material": "Uniform cheap-roof pricing is not a national supply curve; the illustrative 120–140 GWp exceeds the approximately 110 GWp implied by one mixed-source potential diagnostic."

      "reason_material": "Seasonal energy balance cannot choose dependable MW/MWh, and choosing storage size before dispatch biases the cost result."

      "reason_material": "The published CHF 45–75 billion distribution totals and CHF 5.5 billion transmission plan are not a solar-only surcharge, and their scenario capacities are much smaller."

      "reason_material": "The plant comparison begins at commissioning; its construction carry does not include national bridge supply. The 25-year PV sensitivity has zero terminal salvage and is therefore separate from the 30-year base."

      "reason_material": "These change yield and cost comparisons; none justifies discarding the whole source or claiming false precision."
