How much electricity do I use at night?
The easiest way is via the smart meter: your supplier's app or a P1 meter shows your consumption per hour. Without that data, take two meter readings: in the evening before bed and in the morning when you get up.
Standby consumption is what your house always uses, even when nobody switches anything on: the fridge, the router, appliances on standby. You see it as the lowest consumption in the middle of the night. Over a year it is a sizeable part of the bill.
Smart meter and P1 port
Many suppliers and grid operators show your consumption per hour or per quarter hour in their app or on their website. If you want to see it live, you can use a P1 meter: a small device on the P1 port of the smart meter that sends the consumption to an app.
Why it matters
What you use in the evening and at night is what a home battery can cover with solar power from the day. If that is little, a large battery has little to do. It also matters with a dynamic contract, because the night has a different price than the evening.
Without measurement data
The calculator estimates your hourly consumption from your annual consumption, your habits (such as on how many working days someone is home during the day) and the appliances you enter. You can put that estimate next to your own measurement.
