How we calculate this: we assume 1,600 kWh/kWp annual yield, a 0.32 €/kWh retail import price, a 0.10 €/kWh export credit, 40% self-consumption, 0.5%/yr panel degradation and a 25-year lifespan. Savings grow with your chosen price inflation. These figures are indicative estimates for guidance only, not a financial guarantee — get real quotes for binding numbers.
