☀️ Peak sun hours in Greece
Greece is one of Europe's sunniest countries — roughly 4.5 to 5.5 peak sun hours — highest in Crete and the southern islands, a little lower in the north.
| Region | Approx. peak sun hours (annual avg) |
|---|---|
| Crete & southern islands | ~5.1 – 5.5 |
| Cyclades & Aegean | ~5.0 – 5.4 |
| Athens & central Greece | ~4.7 – 5.1 |
| Northern Greece (Thessaloniki) | ~4.3 – 4.8 |

⚡ Electricity prices in Greece
As an EU country, Greece has relatively high electricity prices — commonly around €0.15–€0.25+ per kWh for households depending on tariff and period. Those high rates, combined with excellent sun, make self-generated solar energy very valuable.
💸 Incentives & net metering
Greece operates a net-metering (and net-billing/self-consumption) framework that credits solar generation against consumption, and has run subsidy schemes for rooftop PV and home batteries at various times. Terms are set by regulation and the utility (DEDDIE/HEDNO), so confirm the current net-metering and any grant details before sizing.
💰 System cost & payback in Greece
Grid-tied rough guide (EU pricing):
| System size | Approx. cost | Suits |
|---|---|---|
| 3 kW | ~€3,500 – 5,500 | Small home |
| 5 kW | ~€5,000 – 8,000 | Typical family home |
| 10 kW | ~€9,000 – 14,000 | Large home / small business |

💡 Local insight: Greece
Greece combines two things that make solar pay: some of the best sun in Europe and typical EU electricity prices. A rooftop system in Crete or the southern islands generates markedly more than the European average, and with net metering to bank summer surplus against winter use, payback is attractive — often in the region of 5–8 years. The north is cloudier and cooler, so production and payback are a little more modest there.

❓ Frequently asked questions
How many peak sun hours does Greece get?
About 4.5 to 5.5 — among the best in Europe. Crete and the southern islands are highest; northern Greece a little lower.
Is solar worth it in Greece?
Yes — excellent sun plus high EU electricity prices and net metering give a typical payback of roughly 5–8 years, faster in the sunny south.
Does Greece have net metering?
Yes, Greece operates a net-metering / self-consumption framework via HEDNO/DEDDIE, and has offered rooftop and battery subsidies at times. Confirm current terms before installing.
How much does solar cost in Greece?
Roughly €5,000–€8,000 for a typical 5 kW home system before any subsidy. Get local quotes.
Note: Greek electricity tariffs, net-metering rules, subsidies and prices change over time. These figures are approximate, for planning only — verify with HEDNO/your supplier and a local installer.
