How these offers were matched
Exact manufacturer part number IPWR-M10-54BX2S-440W matches retailer MPN or explicit manufacturer-style merchant SKU; model, voltage/capacity and configuration agree. Same panel MPN and power/bin; offers retain single-panel, pallet or container quantities and individual purchase conditions. Only compute per-panel or price/W using that exact offer package quantity and price_basis; unpriced quotes stay unpriced.
WHAT WE ACTUALLY OBSERVED
Prices have a history.
Observations keep their original source dates and purchase scopes. Historical lows are separate from current availability. Unpriced and configuration-dependent offers are never treated as exact-price lows.
