How We Calculated These Figures
Our estimates are based on 1199 annual sun hours for the North West region, a standard 4kW system with south-facing orientation, and 50% self-consumption ratio. Electricity savings use the current average tariff of 23.8p/kWh, and export income uses the Smart Export Guarantee average of 12p/kWh. Panel degradation of 0.5% per year is factored into 25-year projections.
Actual savings will vary based on your roof orientation, shading, energy usage patterns, chosen system size, and installer pricing. We recommend getting at least 3 quotes from MCS-certified installers for accurate pricing.
