One of the most important factors in determining whether your roof is suitable for solar panels is its orientation. In the UK, a south-facing roof is ideal, as it receives the most sunlight throughout the day; however, east- and west-facing roofs can also generate substantial energy. If your roof is north-facing, solar panel installation may not be as effective.
Another key consideration is shading. If trees, buildings, or other obstructions cast shadows on your roof for extended periods, the efficiency of your panels will be reduced. In such cases, an optimised system with micro-inverters or power optimisers may help mitigate the impact of shading.
Roof size and available space
The amount of available space on your roof will determine how many panels you can install. A standard 4kW solar PV system requires approximately 26 square metres of roof space. Smaller roofs may still accommodate a solar panel, but the system’s output may be limited. Features such as skylights, chimneys, and vents can also affect panel placement and efficiency.
Roof structure and material
The structural integrity of your roof is crucial when considering solar panel installation. Before proceeding, an assessment should confirm that your roof can support the weight of the panels. Older or damaged roofs may require repairs before installation can take place.
Additionally, the roofing material plays a role in determining the ease of installation. Asphalt shingles, metal, and tiled roofs are well-suited for solar panels, whereas thatched or asbestos-containing roofs are typically unsuitable due to safety concerns. If your roof material presents challenges, an installer will assess alternative mounting solutions .

Considerations for listed buildings and conservation areas
While most UK homes can install solar panels without planning permission, properties in conservation areas or listed buildings may require approval. Checking local regulations before proceeding can help avoid unnecessary delays.
Investing in solar panels can be a great way to reduce energy costs and lower carbon emissions. With careful planning, most homeowners can benefit from renewable energy solutions.
