ELPIDA · Curtailment ride-through
Keep your solar online through curtailment.
Cyprus is curtailing more solar every year. ELPIDA is a smart zero-export / curtailment ride-through device that keeps your PV system producing during curtailment and maximises self-consumption, fully compliant with the framework of the Electricity Authority of Cyprus.
Proof of concept demonstrated
DSO-compliant
For installers & PV owners
We're looking for installer partners
ELPIDA's proof of concept is done. Enerthon is now seeking installer partners who want to offer their customers real market value for money, a compliant way to protect a PV investment as curtailment rises.
For PV owners
Stop losing generation to curtailment. Keep your system producing, self-consume more, and stay fully within the rules, without risky unauthorised modifications.

Loss calculator
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.

| Option | What happens | Verdict |
|---|---|---|
| Install ELPIDA | Keeps the system online through curtailment, maximises self-consumption, stays DSO-compliant, at a fraction of a battery's cost. | ✓ The smart fix |
| Do nothing | Lose ~20% of generation next year (~€1,020/yr) and rising; surplus credits now expire every 3 years. | Bleeding value |
| Add extra (illegal) panels | The DSO now inspects and disconnects illegal systems, voids the certificate of suitability, charges investigation costs, and refers cases to the police and CERA for fines. | High risk, not a fix |
| New inverter + battery | Store midday surplus and self-consume later. It works, but it means high upfront cost and possible re-approval. | Effective, expensive |
