Is solar worth it in Scotland?

Yes — payback is longer (11-14 years) but panels last 25-30 years. That's 11-19 years of pure profit. Plus Scotland has higher electricity prices in some areas, improving the economics.

Do north-facing regions get worse payback?

Region (north vs south) affects total sunlight hours. Roof direction (south vs east/west) affects how much you capture. A south-facing roof in Scotland beats an east-facing roof in London.

Does weather really vary that much across the UK?

Annual solar irradiation: London 1,050 kWh/m²/yr vs Edinburgh 900 kWh/m²/yr — a 15% difference. Significant but not dramatic. Cloud cover matters more than latitude in the UK.

What factors matter more than region?

Self-consumption rate is more important than region. A Scottish home using 70% of solar directly (someone home all day) saves more per kWh than a London home exporting 70% at low SEG rates.

Solar payback by region — Payback: 8-10yr in the south, 11-14yr in Scotland. But it's worth it everywhere.

How long do solar panels take to pay back in my region?

Solar panel payback period varies by UK region due to sunlight hours: SOUTH ENGLAND (London, Brighton, Southampton): 8-10 years. Annual yield: 950-1,050 kWh/kWp. SOUTH WEST (Bristol, Exeter, Plymouth): 8-10 years. Annual yield: 950-1,050 kWh/kWp. MIDLANDS (Birmingham, Nottingham, Leicester): 9-11 years. Annual yield: 850-950 kWh/kWp. NORTH ENGLAND (Manchester, Leeds, Newcastle): 10-12 years. Annual yield: 800-900 kWh/kWp. WALES (Cardiff, Swansea): 9-11 years. Annual yield: 850-950 kWh/kWp. SCOTLAND (Edinburgh, Glasgow): 11-14 years. Annual yield: 750-850 kWh/kWp. NORTHERN IRELAND (Belfast): 10-13 years. Annual yield: 800-900 kWh/kWp. KEY: Even in Scotland, solar pays back in under 14 years with 11-19 years of profit remaining.
