S4 In-Roof Solar Mounting System
Premium British-Made Solar Mounting for Every Roof
The S4 In-Roof Mounting System is an innovative, UK-manufactured solar mounting solution designed to provide a fast, secure and aesthetically pleasing installation for residential and commercial solar PV systems.
Built around S4's patented universal mounting technology, the system is engineered to simplify installation while delivering exceptional strength, reliability and long-term performance. Compatible with virtually all modern solar panels, the S4 mounting system offers installers a single, flexible solution for projects of every size.
Whether you're installing on pitched roofs, slate, plain tile, concrete tile, or other common UK roof coverings, S4 provides a professional in-roof finish that integrates seamlessly with the roofline.

The same mounting platform supports:
All standard solar panel dimensions
Landscape and portrait installations
Residential and commercial systems

Future panel upgrades without changing the mounting platform
This dramatically reduces complexity for installers while providing maximum flexibility for every project.
