AnswerHow many solar panels for a 4-bedroom house?
A 4-bedroom UK house typically fits 12–14 solar panels (about 4.8 kWp), depending on roof space and electricity use.
Roof area, orientation and your annual kWh matter more than bedroom count. South-facing is ideal; east–west still works well.

| Cost | £7,680–£9,600 |
| Generation | ~4,320 kWh/yr |
