Consumption-based sizing
We analyse 12 months of your EAC bills and model your evening usage, so the battery is sized to your life, not a one-size box.
Solar battery storage
Stop selling cheap and buying back dear
Under Net Billing, exported solar earns wholesale rates while evening imports cost full retail. A correctly sized battery captures that gap, storing your surplus at midday and spending it after dark.

The Net Billing business case
Why batteries became the default in 2026
Since January 2026, every new PV system in Cyprus connects under Net Billing: surplus you export is credited at roughly €0.08–0.11 per kWh, while the power you import in the evening costs around €0.25. That spread is where a battery earns its keep. Every kilowatt-hour you store at midday and use after dark is worth the full retail rate you avoid paying EAC, not the wholesale rate you'd have earned exporting it.
The effect on a real bill is substantial. A 5kW array generates 25–30 kWh on a sunny Cyprus day while the house behind it consumes 15–20 kWh in total, much of it after sunset. Without storage, the surplus is sold to the grid for cents and bought back at premium evening rates. Pair the same panels with a correctly sized battery and the combination typically covers 85–95% of a household's annual electricity needs.
Battery pricing in Cyprus currently runs €800–1,000 per kWh of storage installed. A typical 10kWh home system totals €8,000–10,000, a compact 5kWh setup proportionally less, and in most homes self-consumption savings return the investment in 6–8 years before any subsidy is counted. The table below shows what that looks like across common household sizes.
State support is moving the same way, just slower than the headlines suggest. The €1,500 residential PV grant closed at the end of 2025, and a dedicated home-battery subsidy has been announced, though as of mid-2026 applications haven't opened. Meanwhile the Save and Upgrade Homes 2026 grant, expected to open in September, lists battery storage among its eligible measures for older homes doing a wider energy upgrade. We track both and prepare your paperwork the moment a window opens.
On the hardware side, we install lithium systems, mostly LFP, rated for 6,000+ charge cycles: 15–20 years of daily use in practice. Modern units weigh 100–125kg, mount cleanly on a wall, and run silently, so a garage or shaded utility room is all the space they need. Cyprus's mild climate helps here, since the cells perform best between 15 and 35°C, which a shaded indoor spot provides most of the year.
You don't need a brand-new solar system to add storage, either. Hybrid-inverter systems accept a battery directly, while older string inverters take an AC-coupled retrofit battery or an inverter upgrade. We assess which route makes financial sense for your setup, and if the honest answer is 'not yet', that's what we'll tell you.
Prices & sizing
What a solar battery costs in Cyprus
Installed prices from our current projects, at €800–1,000 per kWh of storage depending on brand and configuration. Every figure is confirmed with a free sizing assessment of your actual EAC bills.
| Battery size | Typical home | Installed price | What it covers |
|---|---|---|---|
| 5 kWh | Apartment or small home with low evening use | €4,000–5,000 | Lighting, fridge, TV and devices through the evening |
| 10 kWh | 3-bedroom home without a pool | €8,000–10,000 | Full evening and overnight use; saves around €1,800 a year |
| 14–20 kWh | Larger home with a pool or several ACs | €11,200–20,000 | Pool pump, air conditioning and overnight autonomy; €3,000–4,000 a year |
| 30 kWh+ | Commercial premises | Custom quote | Modular banks sized to your operating hours, expandable as you grow |
Sizing follows your evening consumption, not your total daily usage. We model both from 12 months of EAC bills before quoting, so you're not paying for capacity you won't use.
What you get
What's included in every battery installation
Quality lithium systems
LFP and lithium-ion systems rated for 6,000+ cycles, from manufacturers with authorised support in Cyprus. We handle servicing and warranty claims ourselves.
Hybrid inverter integration
New installs get a hybrid inverter from day one; existing systems are assessed honestly for an AC-coupled retrofit or an inverter upgrade.
Backup power option
Keep essential circuits (fridge, lights, internet) running through power cuts with automatic switchover. Grid-tied panels alone can't do this.
All paperwork handled
CERA-certified installation with EAC applications, technical drawings, EN 62619 compliance, anti-islanding protection, and any storage subsidy you qualify for, prepared and filed by us.
Smart self-consumption
Smart controllers prioritise solar, then battery, then grid, automatically maximising the value of every kWh you generate.
How it works
From assessment to stored sunshine
Free assessment
We review your bills and usage patterns to size the battery precisely: no oversizing, no undersizing.
Clear proposal
An itemised quote with expected self-consumption gains and honest payback maths under the current Net Billing rules.
One-day installation
Mounting in the morning, inverter and panel integration in the afternoon, commissioning before we leave. Coastal homes within 500m of the sea get marine-grade enclosures at no extra charge.
Commissioning & monitoring
We configure charge priorities, test backup switchover, and set up your monitoring app so you can watch the battery work from your phone.
FAQ
Frequently asked questions
More questions? Our team is reachable on WhatsApp, by phone, or through our contact form.
How much does a solar battery cost in Cyprus?
Around €800–1,000 per kWh installed. A typical 10kWh home system totals €8,000–10,000, a compact 5kWh setup proportionally less. Where you land in that range depends on the brand, the capacity, and whether your inverter needs upgrading. We quote precisely after a free sizing assessment based on your actual EAC bills.
What size battery does my home need?
Most Cyprus homes need 10–14 kWh to cover the evening and night. A 3-bedroom home without a pool typically suits 10kWh; larger properties with pools and multiple ACs need 14–20 kWh. Sizing is driven by your evening consumption, not your total daily usage, which is why we model it from your bills rather than guessing from house size.
Is there a government subsidy for batteries in 2026?
Not a standalone one yet, but it's coming. A home-battery subsidy was announced in late 2025 and the ministry has signalled a 2026 launch; as of mid-2026, applications haven't opened and no amounts are published. Separately, the Save and Upgrade Homes 2026 grant (expected from September) can fund a battery within a whole-home energy upgrade of a pre-2008 house. We track both and prepare your application the day a window opens; the payback maths above works even without a grant.
How much will a battery actually save me?
Under Net Billing, a kilowatt-hour you'd otherwise export for around €0.08–0.11 is worth about €0.25 when you use it yourself in the evening, so each shifted kWh keeps roughly €0.14–0.17 in your pocket. A household shifting 4,000 kWh a year banks around €600–700 from that spread alone; a typical 3-bedroom home with panels plus a 10kWh battery usually cuts around €1,800 a year in total. We model your exact figure before you commit.
What's the payback period on a battery?
In most homes, 6–8 years at current prices and tariffs, before any subsidy is counted. The batteries themselves are rated for 6,000+ cycles and carry warranties of 10 years or more, so the system keeps saving for years after it has paid for itself. An open storage grant shortens the payback further if you qualify.
Can I add a battery to my existing solar system?
Usually yes. If you have a hybrid inverter, it's a straightforward addition. On older string inverters we assess whether an AC-coupled retrofit battery or a hybrid inverter upgrade makes more sense, and tell you honestly. If you're on the old Net Metering scheme, we check your connection terms as part of the same assessment.
Will my battery keep the power on during a blackout?
With backup capability configured, yes. Essential circuits you choose (fridge, lights, internet, a few sockets) switch over automatically when the grid drops. Worth knowing: a grid-tied PV system without a battery shuts down during outages for safety reasons, so backup is a battery feature, not a panel feature.
How long do solar batteries last?
Quality lithium batteries are rated for 6,000+ cycles, well over ten years of daily use, and typically retain around 80% capacity after a decade; warranties guarantee at least 70%. Cyprus's stable climate helps, and an annual inspection (connections, firmware, ventilation filters) keeps things at their best.
Where is the battery installed, and how much space does it need?
Wall-mounted in a garage, storeroom, or shaded utility area. Modern units weigh 100–125kg, run silently, and look closer to a boiler than to industrial equipment. They perform best between 15 and 35°C, so we avoid direct sun and pick a spot with some ventilation.
