- kWp installed: Latitude-based estimate, accurate within ±15% for residential. PVGIS for serious decisions.
- System cost (€): €1500/kWp default (rough EU residential 2026 average, before subsidies).
- Self-consumption %: Without battery 30%; with smart-home 60%; with battery 80%+.
- Bidding zone: 30-day rolling wholesale average for HU. Real retail higher (taxes + grid fees).
- 25 years assumes panels degrade ~0.5%/yr; inverter typically replaced once around year 12.
