Is Your Roof Suitable for Solar Panels? Here’s What You Need to Know
When it comes to harnessing the power of solar energy, one of the first considerations is whether your roof is suitable for solar panel installation. Here at Nordhaus Group, we’re committed to helping you understand the key factors that determine your roof’s eligibility for a solar photovoltaic (PV) system.
Roof Orientation
A south-facing roof is ideal for generating the maximum amount of electricity, thanks to its prolonged exposure to the sun at its strongest. However, east and west-facing roofs can also yield significant benefits. While a north-facing orientation is less effective, don’t worry if your roof doesn’t perfectly match these ideals; there are still viable options available.
Roof Pitch
Whether you have a sloping or flat roof, solar panels can be installed efficiently. The optimal angle for solar panel installation is between 30-40°, but even if your roof’s pitch falls outside this range, you can still benefit from solar energy. Flat roofs can have panels mounted at an ideal angle using brackets, ensuring maximum energy generation.
Roof Condition
Before installing solar panels, it’s crucial to ensure your roof is in good condition. Any damage or structural weaknesses should be addressed to support the additional weight of the panels. A well-maintained roof not only ensures the longevity of your solar system but also maximises its efficiency.
Roof Shading
Shading can significantly impact the performance of your solar panels. Objects like trees, power lines, and nearby buildings that cast shadows on your roof can reduce the amount of electricity generated. Our certified installers can assess the shading levels on your roof and recommend optimisation solutions to mitigate these effects.
Roof Size
The size of your roof plays a pivotal role in determining how many solar panels can be installed. For a standard 4kW system, you’ll need about 26 square metres of clear roof space. Even with a smaller roof, you can still achieve considerable energy savings by optimising the available space.
Roof Material
Different roofing materials can affect the cost and feasibility of solar panel installation. Most common materials like asphalt and metal are excellent for solar PV systems. However, materials like thatch, asbestos, and glass are unsuitable due to safety and structural concerns. Our experts will guide you through the best options for your specific roof type.
Roof Availability in Conservation Areas
If you live in a listed building or a conservation area, planning permission might be required for solar panel installation. It’s essential to check with your local authority early in the planning process to avoid delays. For most domestic properties, however, solar panels are considered "permitted development" and do not require special permissions.
