Spain offers excellent solar economics: €4,000–€8,000 for a 4–8 kW residential system, with some of Europe's best sun hours (1,800–2,800 annually). The "sun tax" was abolished in 2018, and current IBI (property tax) reductions of 25–50% for 3–5 years are offered by many municipalities. Self-consumption with surplus compensation (autoconsumo con excedentes) allows selling excess energy back to the grid. On the Mediterranean coast, a 6 kW system can produce 9,000–10,000 kWh/year, covering most household needs. Payback: 5–8 years.
