Why self-consumption matters so much
Every additional percentage point of self-consumption improves the economics of the system.
Self-consumption without storage
25 to 35%
Self-consumption with storage
60 to 80%
Strategy 1: Shift programmable appliances
Dishwasher, washing machine and tumble dryer use a lot of electricity – and can easily be programmed to run during peak solar hours (11am–3pm). Modern appliances with timers or smart home controls make this simple.
- Washing machine: set to 12pm–2pm
- Dishwasher: after lunch
- Tumble dryer: right after the washing machine
- Hot water: boost during solar hours
Strategy 2: Integrate heat pump and EV
A heat pump and an electric vehicle can move self-consumption without storage into the typical 25 to 35% range when operated during solar production.
Smart chargers (e.g. myEnergi zappi) only charge when sufficient solar electricity is available.
- EV charged on solar: savings compared with grid electricity
- Heat pump at maximum during day: use more of the solar production
- Smart charger: charges when solar production is available
- Air-source heat pump compatible with all solar systems
Strategy 3: Local Energy Community (LEC)
From 2026, you can sell your surplus electricity directly to neighbours in the same area. In an LEC, you receive more than the feed-in tariff and your neighbours pay less than the grid price – a win-win.
- Setup through the local grid operator
- Especially attractive in apartment buildings and housing estates
Frequently Asked Questions
What is a realistic self-consumption rate without a battery?+
Typically 25 to 35% for a normal household.
Is a home battery worth it purely for self-consumption?+
In most cases yes, if you have high evening and night consumption. If you have an EV or heat pump, self-consumption can already be very high without a battery.
How does a Local Energy Community (LEC) work?+
Neighbours group together and share solar electricity between them. Setup is handled through the local grid operator.
Can smart home systems automatically optimise self-consumption?+
Yes. Systems like Fronius Solar.web, SMA Sunny Home Manager or Loxone can automatically control appliances and maximise self-consumption without manual effort.
