How Much Energy Can a SOLROOF Roof Generate?
Actual production depends on roof orientation, pitch, location and shading. Under UK conditions, a photovoltaic system typically generates approximately 850–1,000 kWh per installed kWp annually.
SOLROOF Project Examples
Roof Area | Installed Capacity | Estimated Annual Production | Estimated Annual Savings* |
79 m² | 2.97 kWp | 2,525–2,970 kWh | £659–£775 |
103 m² | 6.44 kWp | 5,474–6,440 kWh | £1,429–£1,681 |
150 m² | 10.65 kWp | 9,053–10,650 kWh | £2,363–£2,780 |
260 m² | 16.10 kWp | 13,685–16,100 kWh | £3,572–£4,202 |
305 m² | 15.05 kWp | 12,793–15,050 kWh | £3,339–£3,928 |
391 m² | 19.98 kWp | 16,983–19,980 kWh | £4,432–£5,214 |
* Estimated using a residential electricity price of £0.2611/kWh (26.11 p/kWh), corresponding to the UK Ofgem price cap for July–September 2026.
