Plug in solar rules in Switzerland

Checked on 7 November 2026 · Confidence: high

Inverter limit	600 W AC per metered circuit
Panels	Not capped by ESTI
Registration	Written notice to the grid operator before operation
Batteries	Not covered by current rules; a new Swiss guideline is being drafted
Tenants and owners	Not verified yet

ESTI Bulletin 7/2014 still applies: at most 600 W AC per metered circuit, fault current monitoring in the inverter and a written notice to the grid operator.

A federal research report (28 February 2026) found no known damage or injuries from plug in solar and proposes new categories up to 800 W AC (single phase) and 2,400 W AC (three phase), including small batteries. Until a new guideline is published, nothing changes.

PVGIS 5.3 data, European Commission Joint Research Centre, calculated on 8 November 2026 with the same model as our calculator. No shade, inverter limit applied. Own use for a household of 2500 kWh a year with nobody home during the day, savings at a typical local electricity price. The Commission is not responsible for our use of the data.
