Field notes

PV Atlas describes a satellite-analysis pipeline that combines optical and radar imagery with annual 128-value embeddings for each 10 m pixel. It proposes using known arrays as similarity-search labels, estimating panel fractions below a pixel, and comparing observations from 2017 through 2025 to identify installation years. The homepage frames the result as an open national inventory for grid planning, but its headline metrics, sample map, imagery, and several research artifacts are still marked as placeholders.
