Sources & methodology
Savings calculation methodology
Annual generation modelled from PVGIS regional irradiance for an 800W system, 30° tilt, south-facing, with a 0.85 system loss factor (cabling, microinverter efficiency, soiling). We assume 50% self-consumption (the rest exported uncompensated unless on an export tariff) and the Ofgem Q2 2026 electricity price cap of 24.5p/kWh. Saving = generation × self-consumption × price.
All sources
- Ofgem — Q2 2026 default tariff cap
- PVGIS — European Commission solar radiation data
- Bundesnetzagentur — German plug-in solar (Steckersolar) registry
- BSI — British Standards Institution
- BS 7671 Amendment 4 — IET Wiring Regulations
- ONS — UK households and population statistics
- English Housing Survey 2024
- National Grid ESO — carbon intensity
- DESNZ — Energy Trends 2025
- HMRC — 0% VAT on energy-saving materials (until March 2027)
