Is 2026 the best year for solar?

Why 2026 is the best year ever for UK solar: (1) COST: panels are 90% cheaper than 2010 and prices have stabilised. (2) VAT: 0% — saves £1,000-£1,600 (may end March 2027). (3) ELECTRICITY: 24.5p/kWh — 36% higher than 2021. Every kWh saved is worth more. (4) TECHNOLOGY: 400-430W panels, 10kWh batteries, smart tariffs — all mature and proven. (5) PAYBACK: 8-12 years — the shortest ever. (6) ROI: 100-400% — the highest ever. (7) TRACK RECORD: 1.3 million UK homes prove it works. (8) SMART TARIFFS: Octopus Flux/Go/Agile maximise returns. (9) HEAT PUMP SYNERGY: BUS grant makes the complete package affordable. (10) CLIMATE: every kWh from solar replaces fossil fuel. There has never been a stronger financial, technological, or environmental case for solar in the UK. The only question is: are you going to act?
