19/04/2026
Do you pay PPC electricity bills every month? Let's see what you're actually losing in 20 years — and what you'd gain if you switched.
The real numbers
The average Greek pays €180/month = €2,160/year. In 20 years (with a 3%/year increase): ~€58,000 to PPC. Alternatively, a 5kW system costs €5,500 and pays for itself in 5 years.
20-year comparison
| PPC | Photovoltaics 5kW | |
|---|---|---|
| Initial cost | €0 | €5,500 |
| Cost over 20 years | €58,000 | €8,000 (fixed charges + maintenance) |
| Total cost | €58,000 | €13,500 |
| Gain | — | ~€44,500 |
Real-life example
