The Energy dashboard shows cost of energy from grid and solar energy produced and the balance of the two. However, this is far from the real saving achieved by solar panels, I would really like to also see the cost of the solar energy I have consumed, i.e. the cost of all the energy I consume minus the energy my solar system have produced. All the parameters are already in the Energy dashboard configuration, so i’ts just a matter of addming-subtracting and presenting the data in the dashboard. As I am on spot price tariff it’s not so easy to calculate the total savings manually, but all the basic data is already present in the Energy dashbord.
This looks like a duplicate to Add "Solar Cost Saving" option to native Energy Dashboard
Maybe you should vote there too.
