Terraced houses often make excellent canvases for solar panels, yet they are subject to some practical limitations that detached properties may not be. What to know, if you’re thinking about solar for a terrace:
1) Roof space and usable area
The terraced roofs are sometimes small, and for a terrace to be more useful, the distribution of panels might become a little trickier. An installer will design around these issues, but it is useful to know that you may have a limitation on the number of panels you can fit.
2) Roof direction and shading
Roofs facing south are the best, but east-west systems work well too (particularly if your peak power use is in the morning or late afternoon). Additionally, the lack of sun is a bigger problem in terraces due to shade caused by:
Neighbouring rooflines
Chimneys
Tall trees or nearby buildings
Shade can even be an issue for a small percentage of the day, thus make sure that you get your installer to look at it with a proper measurement rather than just guessing.
3) Party walls and access
Terraced homes can be a little more awkward. Installers might require scaffolding that impacts other neighbours, shared alleyways or rear access points. Talking about that upfront so you don’t get surprised on the day of installation.

4) The roof and future repairs
Some roofs are so close to the end of their life that you’ll pay less in total for a new roof than repairing it before installing panels. It will likely cost more in the near future to remove and re-fit panels if you install on an old roof nearing the end.
5) Wiring paths/Installation locations
Your system isn’t just panels. There is an inverter and possibly a battery. Space on a terrace can often be limited, so consider the following when designing:
Loft vs utility room placement
Protecting cables from the roof to the CU
6) Planning permission and restrictions
The vast majority of solar installs are permitted development, but terraced houses in conservation areas and listed buildings could have more regulations. You can double-check by asking your installer what applies locally.
7) How do you use electricity?
Terraced houses can also show specific patterns of use. The payback tends to be quicker for solar if you can use power during the day (washing machine, dishwasher, EV, etc.) If you are only out a normal amount, then time-of-use or battery storage will mean you waste less of that electricity.
