Good morning everyone,
I wanted to ask what your house’s electricity consumption is at night when everything is quiet and sleeping, so what is running continuously?
We have a newly built house, moved in summer 2019. Our building services include underfloor heating (air-to-water heat pump), controlled mechanical ventilation (runs at full power 3 times a day for 2 hours each, then reduced), a photovoltaic system, and otherwise the usual nighttime appliances (phone charger plugged into USB outlet, e-bikes charging occasionally, 2 TVs on standby, Alexas on standby, etc.).
At night, we have a continuous consumption of about 232W (with ventilation running at reduced power and when the heat pump is not producing). I can see this in the app for the photovoltaic system. From 0:00 to 6:30 a.m. we consume about 2.8 kWh.
How about you?
Best regards

Best regards We have installed an 8.05 kWp system on our hipped roof (30°, 6 panels facing south and 18 facing west).

Current yield 2020 (to date): 8443.38 kWh with 7.2 kWp That’s a great yield! East-west or south-facing?
