12 Solar Myths Exposed With Data

What are the biggest solar panel myths?

12 UK solar myths exposed with real data: MYTH 1: 'UK is too cloudy for solar' — FACT: 1.3M UK homes prove otherwise. A 4kW system generates 3,500-4,200 kWh/yr even in the UK (source: PVGIS, re.jrc.ec.europa.eu). MYTH 2: 'Solar panels take 20 years to pay back' — FACT: At 24.5p/kWh, payback is 8-12 years (source: Ofgem price cap, ofgem.gov.uk). MYTH 3: 'You need a south-facing roof' — FACT: East/west roofs produce 80-85% of south-facing output (source: PVGIS orientation analysis). MYTH 4: 'Solar damages your roof' — FACT: MCS-certified installation uses non-penetrating tile hooks; panels actually protect tiles from weather (source: MCS Installation Standard MIS 3002). MYTH 5: 'Solar panels are too expensive' — FACT: £5,500-£9,000 at 0% VAT delivers 100-400% ROI over 25 years (source: EST, energysavingtrust.org.uk). MYTH 6: 'No grants available' — FACT: 0% VAT saves £1,000-£1,600 alone; ECO4 covers low-income households (source: Ofgem ECO4). Every myth is refuted with specific data and cited sources.
