Installed photovoltaic capacity in watts per resident: every PV plant in the federal electricity-production register (BFE/Pronovo, updated daily) located to its commune, cumulative up to the retrieval date, divided by the STATPOP population. Higher means more solar per person. Caveat: new plants are registered with a lag, so the last 12–18 months are under-counted. (Source: BFE Pronovo register)
