Understanding the cost of installing solar panels
Solar Panel Costs
Power up
your home
The average cost of solar panel installation in the UK ranges from £4,000 to £11,000 for a typical residential system. For a standard 3-bedroom home, expect to pay around £5,500 for a 4kW system, while larger properties may require systems costing up to £11,000 or more. Most homeowners see a complete return on investment within 8-12 years, while solar panels continue generating free electricity for 25+ years. Over the system's lifetime, you could save £15,000-£25,000 on energy costs.
It's worth noting that there are some factors that may affect the cost of your solar installation. Such as, your roof type & condition - Slate and tile roofs are straightforward, while flat roofs or those needing repairs may increase costs. Also property access - difficult roof access or multiple stories may require additional safety equipment and labour. All of this is assessed and discussed in our free consultation.
