The 25-year illustration is nominal and undiscounted. It assumes 2.5% annual electricity/export price inflation, 0.4% annual module degradation, annual O&M equal to 1% of initial capex and a 10% inverter allowance in year 12. Generation, self-consumption, export, pricing, roof suitability, DNO requirements and final installed cost must be validated before investment. No finance, tax relief or VAT benefit is included.
