4kW system annual savings breakdown: (1) Bill reduction (self-consumption): 2,000 kWh at 24.5p = £490 (no battery) or 3,200 kWh at 24.5p = £784 (with battery). (2) SEG export income: 2,000 kWh at 4.5p = £90 (no battery) or 800 kWh at 4.5p = £36 (with battery — less surplus to export). (3) Tariff arbitrage (Octopus Flux with battery): buy at 10p, export at 24p = £300/yr. TOTAL: £580 (panels only) to £1,120 (battery + Flux). Each stream is independent — optimise all three for maximum value.
