Quick Answer
For many homes, Solar panel installation can often be completed within one to two days once everything has been approved and scheduled. However, every property is different, so the timescale can vary depending on your roof, the size of the system and any additional work that may be required.
What Happens Before Installation?
Before any Solar panels are fitted, there are a few important steps.
These may include:
- A Solar survey.
- Checking your roof is suitable.
- Confirming the system design.

Your installer will explain if anything is likely to affect the schedule.
