Solar payback in Ukraine (UA-BEI)
8 kWp rooftop system at € 12,000 (€ 1500/kWp), self-consumption 60%. Latitude 50° gives ~1056 kWh/kWp/yr.
Payback period
38.1 years
Annual savings: € 315 · Production: 8448 kWh/year
25-year ROI: -34% (net € — vs system cost € 12,000) (net € -4125 vs system cost € 12,000)

- 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 UA-BEI. Real retail higher (taxes + grid fees).
- 25 years assumes panels degrade ~0.5%/yr; inverter typically replaced once around year 12.
