What Affects Solar Panel Cost?
Six factors determine your final installation price
1System Size (Number of Panels)
Larger systems cost more but generate more electricity and deliver better value per kW.
| Panels | Capacity | Price Range | Cost per kW |
|---|---|---|---|
| 6 | 2.8kW | £4,250-£5,000 | £1,518-£1,786 |
| 8 | 3.7kW | £5,200-£6,000 | £1,405-£1,622 |
| 10 | 4.65kW | £6,500-£7,500 | £1,398-£1,613 |
| 12 | 5.6kW | £7,800-£8,800 | £1,393-£1,571 |
| 14 | 6.5kW | £9,000-£10,500 | £1,385-£1,615 |
Cost per kW decreases with larger systems because installation labour is similar regardless of size.
Calculate how many panels you need →2Battery Storage
Adding a battery increases upfront cost but maximises savings by storing solar energy for evening use.
| Battery Size | Additional Cost | Best For |
|---|---|---|
| No battery | £0 | Daytime usage, budget-conscious |
| 3kWh | £2,500-£3,500 | Small households, 1-2 people |
| 5kWh | £3,500-£4,500 | Average households, 2-3 people |
| 9.5kWh | £5,500-£7,000 | Large households, high evening usage |
A 10-panel system with 5kWh battery typically costs £6,500 compared to £5,500 without battery.

Are Solar Panels Worth the Cost?
Solar panels typically pay for themselves within 6-10 years and continue generating free electricity for 25+ years.
| System | Cost | Annual Savings | Payback Period | 25-Year Return |
|---|---|---|---|---|
| 6 panels | £4,250 | £500-£650 | 7-8 years | £8,000-£12,000 |
| 10 panels + battery | £6,500 | £900-£1,200 | 6-7 years | £16,000-£24,000 |
| 14 panels + battery | £9,700 | £1,200-£1,500 | 7-8 years | £20,000-£28,000 |
Returns assume current electricity prices. Rising energy costs accelerate payback.
