Price per kWh explained
Price per kWh is a fair benchmark to assess quotes. Divide the total investment by usable capacity — that way you compare systems on equal footing, regardless of brand or model.
Larger capacity is usually cheaper per kWh: fixed costs (inverter, installation, enclosure) are spread over more kilowatt-hours. That is why 15 kWh typically shows a lower €/kWh than 5 kWh.
Current ranges by capacity (estimate, 2026)
| Capaciteit | €/kWh | Totaal (indicatie) |
|---|---|---|
| 5 kWh | €618 – €814 per kWh | €2,850 – €3,450 |
| 10 kWh | €509 – €608 per kWh | €3,890 – €5,890 |
| 15 kWh | €468 – €533 per kWh | €6,400 – €7,200 |
Price development
In recent years, price per kWh has fallen due to scale and technical improvements (LFP cells, modular systems). The trend is toward lower €/kWh at comparable quality.
Whether waiting still pays off is uncertain: raw materials, installation costs and subsidies can influence the trend. We do not guarantee future price drops — we do provide a current indication.
What to look for besides price
Warranty and charge cycles
Check factory warranty (often 10 years) and guaranteed charge cycles. That determines lifespan alongside €/kWh.
Brand and quality
A lower €/kWh does not automatically mean the best choice. Look at certifications, service network and inverter compatibility.
Installation included?
Quotes vary in what they include: hardware only, or also mounting, cabling and meter cupboard adjustments.

“Finally a clear benchmark. I could compare my quote directly against the €/kWh range and knew what was reasonable.”
“The calculator gave a realistic estimate. The installer came quickly with a concrete tailored proposal.”
“No sales talk, just clear numbers. Exactly what I needed before making a decision.”
Frequently asked questions
- What is a good price per kWh for a home battery?
- In 2026, a fair range for many systems is between €500 and €800 per kWh, depending on capacity and brand. At 10 kWh you often see €550–650 per kWh; at 5 kWh it can be higher. Use our calculator for an estimate based on your desired capacity.
- Why does price per kWh differ by capacity?
- Fixed costs (inverter, installation, enclosure) weigh heavier on smaller systems. A 5 kWh battery has similar mounting to a larger model, but lower capacity — hence a higher €/kWh.
- Will home batteries get cheaper?
- The trend in recent years has been downward per kWh due to scale and technology. Whether that continues is uncertain: raw materials, labour costs and regulation all play a role. We do not predict guaranteed price drops.
- Is the price inclusive of installation?
- Our ranges are estimates for total project costs, including installation by a certified installer. Exact quotes vary by situation — request a no-obligation tailored quote.
