Solar for Couples UK

What size solar system for a couple?

Solar for couples: the most common UK solar installation scenario. CONSUMPTION: 2,500-3,500 kWh/yr. IDEAL SYSTEM: 3-4kW (8-10 panels). Cost: £5,000-£7,000 at 0% VAT. Generates: 2,700-3,800 kWh/yr — covering 80-110% of annual consumption. SAVINGS: £480-£850/yr without battery. £700-£1,100/yr with battery. Payback: 7-12 years. SELF-CONSUMPTION: If one person works from home: 50-65% (excellent). If both work away: 30-40% (battery recommended). FUTURE-PROOFING: if planning an EV or heat pump, consider installing 5-6kW now (£1,000-£1,500 extra) to avoid the cost of adding panels later.
