Photovoltaic prices per kW in Greece (2026)
Photovoltaic Price per kW in Greece (2026)
Introduction
When looking for photovoltaics, one of the most important questions is: how much does a kW cost? The price per kW is the best way to compare offers and understand if you are paying a fair price.
Average Price per kW in Greece (2026)
| System Type | Price per kW | Note |
|---|---|---|
| On-grid, without battery | €1,200 – €1,800/kW | Most common for residences |
| On-grid with battery (hybrid) | €1,800 – €2,500/kW | Increased autonomy |
| Off-grid | €2,500 – €3,500/kW | Holiday homes / remote areas |
| Commercial (>10kW) | €900 – €1,400/kW | Economies of scale |
Prices include equipment and installation. They may vary depending on the area and equipment.
What Affects the Price per kW?
- System power: Larger systems have a lower price/kW due to economies of scale
- Panel quality: Monocrystalline are more efficient but more expensive
- Inverter type: String, hybrid, or microinverter — different prices
- Battery: Significant impact on total cost
- Installation: Roof type, tilt angle, complexity
- Area: Islands and Southern Greece have higher performance and better ROI
Calculation Examples
| Power | Price/kW | Total Cost |
|---|---|---|
| 3 kW | ~€1,600/kW | ~€4,800 – €5,400 |
| 5 kW | ~€1,500/kW | ~€7,500 – €8,500 |
| 8 kW | ~€1,350/kW | ~€10,800 – €12,000 |
| 10 kW | ~€1,250/kW | ~€12,500 – €14,000 |

How to Compare Offers Correctly?
Don't just look at the total cost. Always compare the price per kW and check what each offer includes:
- ✅ Equipment warranty
- ✅ Installation warranty
- ✅ Quality of panels and inverter
- ✅ Post-installation support
Frequently Asked Questions (FAQ)
How much does a PV kW cost in Greece?
The average price is €1,200–1,800/kW for on-grid systems without a battery. With a battery, it goes up to €1,800–2,500/kW.
Why does the price/kW change with power output?
Larger systems benefit from economies of scale: fixed costs (installation, interconnection) are spread over more kW, reducing the price per kW.
Is the cheapest offer always the best?
Not necessarily. A cheaper price/kW might mean lower quality panels or inverters. Always compare what the offer includes.
Are there subsidies that reduce the price/kW?
Yes! Subsidy programs can reduce the actual cost by up to 40%.
