What does a solar PV system cost?
The installed cost of a PV system will depend upon the roof type, the size of the system, the type of module used and how the system is mounted. We therefore offer a ballpark figure for guidance of between £5,000 – £6,000 per kWp installed. To provide a detailed fixed quote requires a detailed site survey and analysis. A typical family uses 4000kWh per year and this would require a 4kWp system. This would cost approximately £20,000. See domestic estimate calculator.
