EWZ-Solar
Worum geht es?
Das Elektrizitätswerk der Stadt Zürich bietet Solarstrom zum Kaufen an. Für CHF 250.- pro Quadratmeter Solarpanel erhält man pro Jahr 80kWh Strom gutgeschrieben. Ich möchte dies in Home Assistant nachbilden.Berechnungen
- 80 kWh entsprechen 80'000 Wh pro Jahr, das entspricht 219.18 Wh pro Tag, d.h 9.13Wh pro Stunde, entspricht also einer Leistung von 9.13W.
Konfiguration
- I installed PowerCalc which allows to install virtual power sensors in HA.
- I added a PowerCalc-Integration of type “daily fixed” called EWZsolar. I set the unit to “W” and entered 45.7 as value (as we bought 5m^2 solar cells) and I calculated the Power of 9.13W/m^2 linearly out of the 80kWh/year/m^2.
- In the configuration of the energy dashboard I added “EWZsolar energy” to “Back to the grid” (“Zurück zum Netz”).
