Panels, batteries and what you'll export.
£7,000 – £12,600
A typical 4kW system starts around £7,000. Larger 6kW systems run about £9,100, and 8kW+ around £12,600 — batteries are extra.

|---|---|---|
| 4kW system | Typical 3-bed roof, ~10 panels | £7,000 |
| 6kW system | Larger roofs, higher usage | £9,100 |
| 8kW+ system | Big roofs or high demand | £12,600+ |
What actually happens
- Roof survey — orientation, shading and structure checked
- Scaffolding up; mounting rails fixed to rafters
- Panels lifted, fixed and wired in strings
- Inverter installed (garage or loft, usually)
- Connected to the consumer unit; generation meter fitted
- DNO notified, system commissioned and certified

Regulations to know
- Usually permitted development, but flats, listed buildings and conservation areas have limits
- Your installer must notify the District Network Operator (G98/G99)
- MCS certification is needed to get paid for exported power
Tips from the trade
- South-facing is best but east–west pairs work well for all-day generation
- Get the battery decision right at install time — retrofitting costs more
