GENERATION: 10 panels (4kW) = 3,600-4,200 kWh/yr. 14 panels (5.6kW) = 5,040-5,880 kWh/yr. ROOF SPACE: 18-25m². Most 4-bed houses have 30-50m² — ample room. COST: £6,000-£8,500. SAVINGS: £580-£1,000/yr without battery. £850-£1,300/yr with battery. RECOMMENDATION: 12-14 panels (4.8-5.6kW). 4-bed houses have higher consumption and often plan for EV or heat pump — a larger system future-proofs perfectly.
