Solar Panel Mounting Systems

Not when installed correctly by a trusted MCS-certified professional like Naked Solar. For standard pitched slate or tile roofs, we use specialised stainless-steel roof hooks that are securely bolted directly into the structural wooden rafters of your roof—never just screwed into the tiles. These hooks sit flat without putting pressure on the tiles themselves and are finished with heavy-duty weatherproof flashings. The result is a rock-solid, fully waterproofed framework that protects your roof’s integrity rather than compromising it. Our in-house Installation team all graduate through our Planet Maintenance academy, ensuring the highest standards our met no matter your roof type.

The main difference between these two solar mounting styles is aesthetics and how they sit on the property. On-roof systems mount a rail on top of your existing tiles using specialised roof hooks. In-roof (integrated) systems replace a section of your actual roof tiles entirely, sitting flush with the rest of your roofline like a skylight (this is ideal for new builds and re-roofs). While in-roof mounting offers a sleeker, low-profile look, in-roof systems are typically 2–5% less efficient due to reduced airflow and ventilation. In contrast, on-roof systems are easier to ventilate, generally cheaper, and compatible with almost any existing roof type.

Whilst it’s true South Facing roofs are primed for maximum generation,Naked Solar have installed many non-south facing installs which have delivered for our customers energy needs. In some cases maximum generation may not be right for your needs. As most arrays generate more energy in the summer than your property can use and don’t generate enough in the winter, having an array with a steeper pitch than normal, e.g. 60°, would increase your winter generation and reduce your summer generation. Check out our environmental factors page for more information.

Quality mounting gear is engineered from marine-grade aluminum and stainless steel designed to withstand extreme wind loading and coastal weather. Because the panels are clamped tightly into a continuous, interlocking matrix close to the roof surface, wind passes smoothly over them rather than catching underneath. Expert Solar Installers like Naked Solar take care to ensure your Solar system is safe, reliable and durable for many years to come.

For the vast majority of UK homes, absolutely. Standard on-roof solar PV systems and their aluminum-and-steel mounting hardware add an extra load of roughly 10 to 12 kg per square meter to your roof. To put that into perspective, that is often significantly less than the weight of a heavy layer of snow or standard concrete roof tiles. Before every installation, our team conducts a structural assessment to ensure your rafters are fully up to the task.
