🏡 Case Study: Slate Roof Solar PV with Solar Thermal Mounts & System Optimisation

Client Brief
The client required a 16-panel solar PV system installed on a newly constructed slate roof, with provisions to add solar thermal collectors later. They wanted a clean, flush finish to preserve the aesthetic of the slate and ensure long-term waterproofing integrity. Additionally, the system needed a service and individual panel-level optimisation.

Challenges

• Delicate slate roofing required non-invasive mounting

• Needed future-proofed structure to support additional thermal collectors

• Risk of water ingress without proper flashing

• Underperformance suspected on one panel requiring diagnostics and optimisation

Solution
We delivered a tailored solar PV installation using:

• Renusol slate hooks for secure, low-profile mounting between slates

• Genius flashing kits to create a watertight seal around all hooks and penetrations

• Flush-fit racking system preserving the slate roof’s visual appeal

• Full system servicing and performance check

• Installation of a panel-level optimiser on one underperforming module to improve generation and reduce shading losses

Results

• Aesthetically pleasing and structurally sound installation

• Water-tight integrity maintained with no disruption to the roof

• Thermal mountings in place and ready for expansion

• Improved system performance and panel diagnostics thanks to optimiser

• Delighted client with long-term energy savings and a scalable renewable setup
