Photovoltaics with a battery are the most modern solution for those who want true energy independence. Unlike traditional photovoltaics, they store the energy produced during the day and use it at night or during periods of increased demand.
This means you are not entirely dependent on the grid and can drastically reduce electricity costs.
Advantages of photovoltaics with a battery
Cost of Photovoltaics with Battery 2026
The cost depends on the power and storage capacity of the battery. Indicatively:
- 5kW with battery: €8,000 – €12,000
- 10kW with battery: €13,000 – €18,000
Although the initial cost is higher, the savings are significantly greater in the long run. Subsidy up to 40% through "Exoikonomo – Autonomo" (Save – Become Autonomous).
Payback & Performance
Photovoltaics with a battery have a payback period of 5 to 7 years, depending on usage and electricity price.
With a lifespan of over 20–25 years, they are one of the most efficient energy investments.
