For the same one-square-meter area, which receives more solar energy over the course of a year London or Seattle

Archived study

Compares matched-period sunshine-duration normals for London and Seattle and exports the standardized annual totals. The session explains its conversion to a one-square-metre illustrative comparison.

Interpretation and limits

Sunshine duration is a proxy, not measured global horizontal irradiation. The one-sun-equivalent calculation must not be interpreted as actual annual solar energy received by a panel.

Package and provenance

The original .science export and matching poster are preserved byte-for-byte from the upstream case. The package contains the conversation, session metadata, and the resources inventoried in its internal manifest. This introduction summarizes the archived record; the research, external sources, and model evaluations were not rerun for this import.
