How these offers were matched

Exact manufacturer part number, same manufacturer and 440.0W bin, and identical source technical title after removing only terminal package/clearance sale labels. No fuzzy-title merge. Matching known electrical/design specs were checked; source collision flags and conflicting wattages/specs are excluded. Purchase units and minimum orders remain separate on each offer.

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.

How to verify the model and scope

Rated power is a starting point.

Conceptual panel-energy map, not a prediction for this product. A watt rating does not establish daily watt-hours; location, season, shade, orientation, temperature and system losses still matter. Explore seasonal solar assumptions
