Information
5 kW Solar PV — UK Annual Savings
A 5 kW solar PV system in the UK typically produces around:
~4,000–4,500 kWh per year (average ~4,250 kWh)
Estimated Yearly Savings
How much you save depends on how much solar energy you use yourself vs sell back to the grid.
Typical figures in the UK (2026 electricity prices):
| Use Pattern | Self-Use | Export | Estimated Savings |
| Typical home | 40% | 60% | £550 – £800 / year |
| Higher self-use | 50% | 50% | £650 – £850 / year |
| Battery / daytime use | 70% | 30% | £800 – £1,000+ / year |
How It Works
- Self-used solar energy replaces electricity you’d buy — saving ~24.7 p per kWh.
- Exported energy is sold to the grid under the Smart Export Guarantee (SEG) — typically ~5p–15p per kWh depending on tariff.
- The more you use during daylight hours, the more you save.
What This Means
A 5 kW system can save most UK homes £550–£1,000+ per year on energy bills — and more if you use most of your solar electricity as it’s generated.
