A monthly, postcode-aware release tracking distributed battery adoption, solar attachment and the source vintages behind the market record.
Geography
Postcode to territory
Cadence
Monthly vintage
First source
CER installations
Compare where distributed storage is accumulating, separate installation flow from installed stock, and identify markets where adoption evidence has materially changed.
Official small-scale records are revised and arrive with a lag. Each edition therefore names the source vintage, preserves prior observations and distinguishes installations recorded in the period from cumulative installed stock. A silent overwrite is treated as a data-quality failure.
Edition ledger
Preparing state. The first edition will preserve postcode source vintage and revisions instead of presenting a silently changing snapshot.

Open core
The first national edition remains in preparation until the postcode crosswalk and source-vintage checks pass. The existing SWIS Rooftop Solar Atlas is the public proof of the geographic method.
The scope becomes a named entitlement and versioned release. Public findings stay open, and every figure stays named to its source.
