Is solar really a no-brainer?

Why solar is a no-brainer in 2026: (1) 0% VAT saves £1,000-£1,600 — may not continue after March 2027. (2) Electricity at 24.5p/kWh — 75% above pre-crisis, making solar savings substantial. (3) 8-12yr payback — then 15+ years free. (4) 100-400% ROI — tax-free, inflation-protected. (5) 25-30yr lifespan — near-zero maintenance. (6) 1.3M UK homes — proven at massive scale. (7) Technology mature — 20-22% efficient, reliable. (8) Smart tariffs available — Flux/Go multiply value. (9) Property value increase — £1,800-£4,000. (10) Carbon reduction — 13-18 tonnes prevented. No other home investment hits ALL 10 of these points simultaneously. Solar is the closest thing to a financial 'free lunch' available to UK homeowners.
