What Changed on October 1, 2025? {#what-changed}
The Cyprus Ministry of Energy, Commerce and Industry officially ended the net metering scheme for all new photovoltaic installations on October 1, 2025. This policy shift, announced earlier in 2025, aligns Cyprus with European Union renewable energy directives and addresses critical grid stability issues that have plagued the island.
The Timeline
- Before October 1, 2025: Net metering applications accepted with 1:1 credit system
- October 1, 2025: Net billing becomes mandatory for all new installations
- Current Status: Existing net metering contracts remain valid until expiration
- Future Outlook: All systems will eventually transition to net billing or hybrid models
According to Cyprus Mail’s energy sector analysis, the government allocated an additional €8 million to support vulnerable consumers through this transition, bringing the total solar support budget to €20 million for 2024-2025.
Why the Change?
Cyprus experienced unprecedented renewable energy curtailment in 2024-2025:

- 29% of renewable energy curtailed in 2024 (source: pv magazine)
- 58% curtailment rate in early 2025 – the highest in EU history
- 145 GWh of solar power wasted – enough to power 28,000 households annually
- Grid instability due to Cyprus’s isolated electricity network with no continental interconnection
The net billing system incentivizes energy storage and self-consumption rather than grid export, addressing these critical infrastructure challenges while maintaining economic viability for solar investments.
Net Metering vs Net Billing: Key Differences {#key-differences}
Understanding the fundamental differences between these two systems is essential for making informed decisions about your solar investment.
Net Metering (Before October 1, 2025)
Net metering operated on a simple 1:1 credit system:
| Feature | How It Worked |
|---|---|
| Export Rate | 1:1 credit – every kWh exported = 1 kWh credit |
| Billing Period | Quarterly rolling credits |
| Credit Expiry | Credits carried forward indefinitely |
| Grid Dependency | High – system designed for maximum export |
| Storage Incentive | None – no advantage to storing energy |
| Financial Model | Predictable, straightforward ROI |
Example: If your 8kW system produced 1,000 kWh but you only consumed 400 kWh, you received full retail credit for the 600 kWh exported. These credits offset future consumption at the same retail rate you pay EAC (Electricity Authority of Cyprus).
Net Billing (After October 1, 2025).
Net billing introduces a market-based compensation structure:
| Feature | How It Works |
|---|---|
| Export Rate | Wholesale rate (approximately 40-60% of retail) |
| Billing Period | Monthly settlement |
| Credit System | Monetary credit at wholesale rate vs retail consumption charges |
| Grid Dependency | Lower – incentivizes self-consumption |
| Storage Incentive | High – battery storage significantly improves economics |
| Financial Model | Variable, dependent on consumption patterns |
Example: Same 8kW system producing 1,000 kWh with 400 kWh consumption. You pay retail rate (€0.30/kWh) for energy drawn from grid, but receive wholesale rate (€0.12-0.18/kWh) for 600 kWh exported. The economic gap makes self-consumption and storage much more attractive.
Visual Comparison: Monthly Bill Calculation
Net Metering Scenario:
- System Production: 1,200 kWh
- Home Consumption: 900 kWh
- Grid Import (night): 300 kWh
- Excess Export: 600 kWh
- Net Bill: (300 kWh import – 600 kWh export credit) × €0.30 = €0 (with 300 kWh credit carried forward)
Net Billing Scenario:
- System Production: 1,200 kWh
- Home Consumption: 900 kWh
- Grid Import (night): 300 kWh
- Excess Export: 600 kWh
- Net Bill: (300 kWh × €0.30) – (600 kWh × €0.15) = €90 – €90 = €0 (break-even at best)
The difference becomes dramatic without optimizing for self-consumption.
Who Is Affected and How? {#who-is-affected}
Existing Net Metering Customers (52,125 systems)
Good News: Your existing net metering contract remains valid. The EAC cannot force you to switch to net billing until your contract expires.
Important Considerations:

Frequently Asked Questions {#faq}
General Questions
Q: Can I still benefit from solar under net billing?
A: Absolutely. While net billing reduces export compensation, properly designed systems with 70%+ self-consumption achieve similar payback periods (4-6 years) to net metering systems. Battery storage closes the gap further.
Q: What happens to my existing net metering contract?
A: Existing contracts remain valid until expiration. The EAC cannot force mid-contract transitions. Monitor your expiration date and plan accordingly.
Q: Is battery storage mandatory under net billing?
A: No, but highly recommended. Systems without storage rely entirely on daytime self-consumption, limiting financial performance. Storage adds €4,000-6,000 but improves ROI significantly.
Q: How much can I save with solar under net billing?
A: Typical 6kW system saves €2,000-2,500 annually with 70-80% self-consumption. With battery storage, savings increase to €2,400-2,800 annually while providing energy independence.
Technical Questions
Q: What size battery do I need?
A: Calculate evening consumption (6 PM – 7 AM). Most households need 7-10 kWh capacity. Oversizing provides backup power but increases costs. Our solar calculator provides personalized recommendations.
Q: Can I add battery storage to my existing system?
A: Yes, both net metering and net billing systems can add storage. Lighthief specializes in retrofit installations, ensuring compatibility with existing inverters or recommending hybrid inverter upgrades.
Q: Will my panels work during blackouts with net billing?
A: Only if you have battery storage with backup capability. Grid-tied systems without storage shut down during outages for safety, regardless of net metering or net billing status.
Q: How does virtual net billing work?
A: Virtual net billing allows system installation at a different location than consumption (e.g., agricultural land). Production credits apply to your residence electricity bill at the same net billing rates.
Financial Questions
Q: Are green loans still available?
A: Yes. Hellenic Bank and Bank of Cyprus offer green energy loans with competitive rates (2.5-4.0% APR). These enable €0 upfront installations with monthly payments often lower than electricity bill savings. See our detailed green loan analysis.
Q: Can I claim VAT back on commercial systems?
A: Yes, VAT-registered businesses can reclaim 19% VAT on both PV and battery systems. This significantly improves commercial project economics.
Q: What grants are still available?
A: Battery storage grants (up to €3,000) remain active. PV system installation grants ended September 30, 2025. Check Ministry of Energy portal for current programs.
Q: How do I calculate my break-even point?
A: Formula: (Total System Cost – Grants) / Annual Savings = Payback Years. Our fotovoltaiko installation guide includes detailed ROI calculators.
Future Outlook
Q: Will net billing rates change?
A: Likely yes. Wholesale rates fluctuate with EAC’s avoided cost calculations. The Ministry reviews compensation rates annually. Storage protects against unfavorable rate changes.
Q: Is Cyprus planning time-of-use tariffs?
A: Not officially announced, but likely within 3-5 years as smart meter deployment completes. This would further advantage storage-equipped systems.
Q: What about the EuroAsia Interconnector project?
A: The subsea cable to Greece (scheduled for 2029-2030) will reduce curtailment and stabilize wholesale rates. However, it won’t fundamentally change net billing economics for residential consumers.
