Roof array on a terraced house
A domestic array on a mid-terrace house, installed from the street with no rear access.
Terraces are the most common domestic solar job and the most constrained. Access is from the front, the scaffold has to go up on a public footpath, and the roof is shared with neighbours on both sides.
None of that makes the job difficult. It just means the planning matters more than the installation.
