Keep your solar online through curtailment.
Cyprus is curtailing more solar every year. ELPIDA is a smart zero-export and curtailment ride-through device that keeps your PV system producing during curtailment and maximises self-consumption, within the framework of the Electricity Authority of Cyprus.
- Keeps generation online through curtailment events
- Maximises the solar you use on site
- DSO-compliant, with no unauthorised modifications
to the Cyprus authorities
Curtailment switches your solar off.
ELPIDA keeps it working for you.
When the grid tells your system to stop exporting, ELPIDA keeps the inverter running and steers the power into your own loads instead of losing it.
Rides through curtailment
Your PV system keeps producing during curtailment events instead of shutting down.
Maximises self-consumption
Generation that would have been curtailed goes to your own consumption on site.
Within the rules
Built around the DSO’s zero-export guidelines, so you stay compliant without risky, unauthorised changes.
Works with what you have
Quick installation alongside your existing inverter. Tested with Huawei, Fronius, SolarEdge and SolaX.
A fraction of a battery
Recovers value from curtailment for €500 installed, instead of a new inverter and battery.

What is curtailment costing you?
Enter your system size and install year to estimate the value of generation lost to curtailment over the life of your net-metering contract.
Assumptions
Specific yield 1,700 kWh/kWp/yr · Energy value €0.30/kWh · Net-metering term 15 years (residential A1). Your contract ends in 2037. Full annual generation value: €5,100.
This year (2026)
€510
Next year (2027)
€1,020
Total to end of contract
€17,085
Year-by-year value of curtailed generation. Dimmed bars to the left (2024–25) are shown as context; the headline total runs from 2025 to the end of your contract.
Curtailment schedule (Enerthon projection):
2024 → 1% · 2025 → 5% · 2026 → 10% · 2027 → 20% · 2028 and onward → 30%.
2024 (1%) and 2025 (5%) align with the EAC’s reported residential curtailment. 2026 onward is Enerthon’s forward projection, consistent with rapidly rising installs, system-level curtailment already far higher, and net-metering credit expiry. These figures are assumptions, not settled fact.
This is the gross value of curtailed generation. A portion is recoverable through self-consumption when your usage coincides with production, which is exactly what ELPIDA maximises.

| Question | Install ELPIDA | Do nothing | Add extra (illegal) panels | New inverter + battery |
|---|---|---|---|---|
| What happens | Stays online through curtailment and self-consumes more | Lose ~20% of generation next year (~€1,020/yr), and rising | DSO inspects and disconnects illegal systems | Stores midday surplus to use later |
| Compliance | DSO-compliant | Compliant, but surplus credits now expire every 3 years | Certificate voided, investigation costs, referral for fines | May need re-approval |
| Cost | €500 per device, installed | Growing annual losses | High risk | High upfront cost |
| Verdict | The smart fix | Bleeding value | Not a fix | Effective, expensive |

Why ELPIDA exists.
How Cyprus’s solar landscape changed, and how ELPIDA was built in response.
Curtailment begins to bite
Cyprus materially increases PV curtailment as solar capacity grows. Residential curtailment reaches ~1% in 2024 and ~5% in 2025; system-level curtailment runs far higher.
Self-consumer rights strengthened
A law amendment strengthens self-consumers’ rights, consumers protest curtailment losses, and CERA issues a decision on connection terms.
DSO zero-export circular
The DSO publishes zero-export guidelines. Enerthon develops ELPIDA in response and demonstrates a working prototype to the EAC and to the OEB employers’ federation.
Net metering closes, credits reset
“Photovoltaics for All” ends and net metering closes to new applicants. The first surplus-credit reset takes effect, and illegal installs are confirmed for disconnection.
Common questions.
What does ELPIDA cost?
€500 per device, including installation, excluding VAT. Installer partner pricing is available.
Will it work with my inverter?
ELPIDA installs alongside your existing inverter. It has been tested with Huawei, Fronius, SolarEdge and SolaX. Tell us your inverter model and we will confirm.
Is it legal?
Yes. ELPIDA is built around the DSO’s zero-export guidelines. Unlike adding extra panels, it does not put your certificate of suitability at risk.
Do I need approval?
An application to the EAC/DSO is part of the process. Enerthon assists you with the application template.
Is ELPIDA cheaper than a battery?
Yes. A new inverter and battery also works, but it means a high upfront cost and possible re-approval. ELPIDA recovers value from curtailment at a fraction of that cost.
