Are solar panels good for warehouses?

Warehouses are the BEST commercial solar opportunity in the UK: (1) HUGE FLAT ROOFS — 500-10,000m² of unobstructed space. (2) DAYTIME OPERATIONS — loading, lighting, forklift charging, HVAC all match solar hours. (3) SCALE ECONOMIES — cost per kW drops significantly at 50-500kW. (4) FAST PAYBACK — 4-7 years for large systems. Typical installation: 100-500kW (250-1,200 panels). Cost: £80,000-£350,000 (before tax relief). Annual savings: £15,000-£80,000+. Enhanced Capital Allowance: deduct 100% from taxable profits in year one (25% corporation tax saving = £20,000-£87,500 effective reduction). Business rates: exempt for systems under 50kW; minimal impact above. Roof survey essential: check structural capacity for additional load (12-15 kg/m²).
