Can you install solar panels on a slate roof?

For UK residential and businesses with slate roofs, concerns about whether solar panels can be installed without causing damage are common. Slate roofs are valued for their classic aesthetic and durability, yet their delicate nature presents unique challenges for solar panel installation. This guide will explain how solar panels can be effectively installed on slate roofs while ensuring functionality, safety, and preservation of the roof’s integrity.

Why is Installing Solar Panels on Slate Roofs Challenging?

Slate roofing, while durable, is brittle and prone to cracking under pressure or improper handling. This makes traditional solar panel installation methods unsuitable, as drilling into the slate can lead to irreparable damage. Additionally, the uneven surface of slate tiles adds complexity to securing mounting brackets.

However, advancements in solar technology and specialised installation techniques have made it possible to safely install solar panels on slate roofs without compromising their structure or aesthetics.

How Are Solar Panels Installed on Slate Roofs?

The installation of solar panels on slate roofs requires a meticulous and specialised approach to ensure the integrity of the roof is preserved. Below is Kembla’s preferred and best practice method of installation:

Careful Removal of Slate Tiles

• Instead of drilling directly into the tiles, specific slate pieces are carefully removed to allow for mount installation.
• This process requires the use of specialised tools, such as slate rippers, to avoid cracking or damaging of tiles.

Installation of Flashing Kits and Roofhooks

• Flashing kits are installed to create a watertight seal around the mounting points.
• Roofhooks are securely fixed to the rafters beneath the slate tiles, providing a robust base for the mounting brackets.

Specialised Mounting Systems

• Non-invasive mounting systems or hooks are used to attach the solar panels. These systems are specifically designed for slate roofs to distribute weight evenly and prevent damage to the delicate tiles.

Reinstallation of Slate Tiles

• Once the mounting is in place, the removed slates are trimmed and carefully reinstalled around the flashing kits/ roofhooks, preserving the roof’s aesthetic and structural integrity.

Mounting the Solar Panels

• Once the slates are re-installed and waterproofing completed, mounting rail will be installed to the roof hooks.
• The solar panels are then installed onto the rail and clamped into position, ensuring that the load is evenly distributed across the roof structure.
• Installers ensure proper alignment for optimal energy efficiency.

Final Weatherproofing

• High-quality sealants and additional flashing are applied around the mounting points to protect the roof from water ingress and environmental elements.

Cable entry

• DC cables will be entered through a separate flashing kit to ensure waterproofing and compliant installation.
