I have been operating my photovoltaic system for a few days now, which has the pleasant side effect that I am recording my household electricity consumption.
The big surprise, (which I had internally expected anyway), is already the baseline load. Even when no one is at home, I basically have a constant draw of 250-300W, which amounts to 6-7 kWh in 24 hours alone. Over a year, that is 2,500 kWh, without cooking, hair dryer, oven, heating, hot water, etc...
Basically, it's "only": refrigerator, devices on standby, router, NAS, inverter, heating control, multiswitch, cable amplifier, modem and things like that...
I was quite surprised by that. The consciously used electricity like lighting, washing machine, dryer, dishwasher, oven, hob, toaster, hair dryer, Thermomix etc... adds up to roughly another 5 kWh spread over the day (although we have almost all highly efficient devices).
In addition, hot water amounts to pretty much exactly 3 kWh per day, and depending on the outside temperature, of course, the heating as well. So far, that fluctuates between 0 and 8 kWh per day. These values come from the time before the photovoltaic system.
