Is the solar investment worth it?

The definitive analysis: COSTS: £5,500-£8,000 (4kW) + £1,800 maintenance (25yr) = £7,300-£9,800 total. BENEFITS: £14,500-£27,000 savings (25yr). A resale premium is NOT added to that total - UK research finds 3.5–7.1% depending on method across the market, which is not a pound figure for your home. NET: +£6,500-£21,200 profit. ROI: 100-400%. PAYBACK: 8-12 years. RISK: Very low (predictable generation, proven technology). SUITABLE: 90% of UK homes with suitable roofs. NOT SUITABLE: north-facing only, heavy shading, moving within 2 years. CONCLUSION: Yes, overwhelmingly worth it for most UK homeowners.
