Press Release

As Perlight Solar’s official representative, we are excited to showcase our innovative Sandtoft In-Roof Solar (IRS) panel, developed in collaboration with Wienerberger.

This partnership has combined Perlight’s cutting-edge solar technology with Wienerberger’s expertise in roof tiles, resulting in a highly efficient and aesthetically pleasing solar solution that has gained significant traction among UK housebuilders.

Pioneering Sustainable Home Energy

The IRS panel highlights our strong dedication to developing innovative, sustainable solutions for modern homes. Its interlocking design allows for the installation or removal of each panel in under a minute, making the process quick and efficient for installers.

These high-performing solar tiles are directly mounted onto the roof, seamlessly integrating with various architectural styles to create a unique, sleek, and modern appearance. Westech’s intuitive, free web design software, Westech-AI, empowers you to design your roof and calculate everything you need for your in-roof solar kit.

Why Are Housebuilders Across the UK Choosing IRS Tiles?

Housebuilders across the UK are choosing IRS tiles, not only because they are developed in partnership with the trusted roof expert Wienerberger, but for their seamless integration, easy installation, and superior durability. Each lightweight panel, designed to connect in under a minute, mounts directly on battens without the need for trays, creating a tiled effect and preserving the traditional roof aesthetic while providing modern solar energy.

The IRS system independently tested for wind resistance, weatherproofing, and fire safety, is MCS certified for roof pitches as low as 15 degrees. Additionally, the IRS holds an Environmental Product Declaration (EPD) certificate, ensuring transparency in environmental impact and helping housebuilders meet sustainability standards.

With a minimal number of parts, no plastic components, and a robust interlocking design, IRS tiles provide an ideal solution for sustainable and resilient roofing.
