Every default is overridable per request. The full bibliography — 8 Swiss and 8 international sources — is served at /api/v1/battery/references.

Data Disclaimer

Battery dispatch, ageing and economics are modelled from the PV and load time series supplied in the request, using published Swiss and international reference values. Actual storage performance and returns depend on the specific product, installation, tariff structure and usage pattern, and on future electricity prices. These calculations are for planning purposes only and are not investment advice.
