I have seen these signs starting to appear on buildings and switchroom doors here in Switzerland. Are they just a local thing or do other countries use similar warnings?

Yes, the image in the OP is the latest in the CENELEC Harmonized wiring code, but the latest IEC symbol, which we ought to be using really, is IEC 60417 no. 6400
Some countries, however, have government guidance which requires another approach.
In the UK, we have just introduced, in PAS 63100 and also reflected in Fig 57.2 of the latest Draft for Public Comment of BS 7671 (our national wiring code) a further composite symbol that shows the solar PV has a storage battery associated with it. This could be depicted on a yellow background. (Below from Figure 4 of PAS 63100)
Some UK industry guidance (e.g. IET Code of Practice for Electrical Energy Storage Systems, 3rd Edition 2024) recommends the notice at the origin of the installation (where UK emergency responders would typically remove the supplier's service cutout) also indicates the location of the storage battery in the premises.
