What does a home battery cost?

You want to know what a home battery costs before you look any further, and that makes sense. The home battery price simply cannot be captured in a single figure, because every home and every consumption pattern is different. What you ultimately pay depends on the capacity you need, the power of the system and the installation situation at your home.

On this page we explain which factors determine the price and why we only give a concrete amount after a site visit. That way you know what to look out for when comparing quotes, without us tying you down to figures that do not apply to your situation.

The biggest factor is capacity, expressed in kWh. A 5 kWh battery stores less energy than a 10 kWh model, and that difference is reflected in the price. Power also plays a role: how many kilowatts the battery can supply or absorb at once determines whether it can help cover heavy consumers such as a heat pump or charging point.

Placement also counts. The distance to your meter cupboard, the cabling, whether a separate inverter is needed and whether we install the battery indoors or in a technical room all influence the installation cost. A home where the electrical installation is already prepared for expansion requires less work than a situation where we first have to make adjustments.

Many people specifically search for a home battery 10 kWh price or a 5 kWh price, because those are common sizes. Yet capacity is not a goal in itself. A larger model costs more, but only delivers extra if your consumption and generation actually make use of that storage. A battery that you rarely fully charge or discharge is more expensive than necessary.

That is why we first look at your annual consumption, your consumption pattern and your generation before we propose a capacity. If you want to go into this in more depth, you can read more at which capacity suits your situation.

A figure without a site visit is a guess, and a guess does not help you with an investment like this. We want to see what your meter cupboard looks like, what you generate with any solar panels, how you consume and which inverter you have. Only then can we propose a system that fits and put a fair price on it.

What a home battery yields also depends on your home, your consumption, your installation and energy prices. Subsidies and any benefits differ by situation and by moment. We work that out together with you based on your real data, not on an average that happens to be circulating somewhere.
