What does home battery installation cost in 2026?

A complete installation costs on average € 3,500 to € 8,000, including mounting and connection to a dedicated circuit. The storage capacity (kWh) and the brand mainly determine where you land in that band. Coupling a battery to existing solar panels costs € 350-900; if the fuse box needs preparing first, allow € 350-950 extra.

No, deliberately not. We are not a shop: we match your request with up to 3 vetted installers from your region. The installer supplies and installs the battery; you compare the quotes and choose brand, capacity and price yourself — or choose no one, that's fine too.

No, a battery also works without panels: with a dynamic energy contract it can charge during cheap hours and discharge during expensive ones. Still, combining it with your own solar power is the most common reason for a battery: you use more of your own generation yourself. What it delivers in your situation differs per household — have it calculated.

The net-metering scheme for solar power fed back to the grid is being phased out. Feeding back gradually becomes less attractive and storing your own power relatively more interesting. How much that matters for you depends on your contract and consumption — we deliberately mention no years or amounts here; check the current status with the national government and have your situation calculated.

There is no universal answer: the payback time depends on your consumption, your contract (fixed or dynamic), your solar panels and the purchase price. Be wary of anyone promising a fixed payback time without knowing your consumption. A consultation with payback calculation (€ 95-250, often offset against the job) gives you the answer for your situation.

Common spots are a garage, indoor storage room or utility room: dry, ventilated and preferably close to the fuse box. Outdoors is also possible, on the facade or in a weatherproof outdoor cabinet. Not every spot is suitable — a battery is heavy and needs space around it; the installer assesses the spot during the survey.

Not necessarily: there are home batteries for single-phase and for three-phase connections. The connection does determine how much power the battery can charge and discharge at once. The installer sees at a glance in your fuse box what you have; if fuse-box work is needed, it costs € 350-950 as part of the installation.

Yes. Submitting a request costs nothing and commits you to nothing. You receive up to 3 quotes and choose yourself — or no one, that's fine too. Prices and payment are arranged directly with the installer.

Installers in your region respond as soon as possible with a price indication or quote. A home battery is a planned job: from request to installation, allow a few weeks depending on demand and battery delivery time.

Yes. We verify Chamber of Commerce registration at onboarding and ask for proof of business liability insurance. Connecting a home battery is electrical work: the affiliated companies are certified electricians or installation firms.

Your details are shared only with the (up to 3) installers matched to your request. We never resell your data and automatically delete requests after the legal retention period. See our privacy policy.

Yes. For commercial buildings, affiliated companies design tailored battery storage: shaving peaks, making better use of own solar power or backup power. Commercial storage is per project and quote-based — choose 'Commercial battery storage' in the request and include your consumption situation.
