More About Solar Panel Mounting Systems

Choosing the correct solar panel mounting system is essential for a safe, compliant and long-lasting solar PV installation. The mounting structure must suit the roof type, fixing method, module layout, approved clamping zones, structural loading, wind exposure and site conditions.

For UK solar PV projects, installers should also consider MCS guidance, product certification, wind uplift, fire performance, weathertightness and manufacturer installation instructions, particularly where the mounting system connects to the roof structure or forms part of the building fabric.

UK Solar Mounting Compliance and PV System Selection

MCS 012 is a key UK standard for solar mounting products used in above-roof and roof-integrated PV installations, covering areas including structural stability, wind uplift resistance, fire performance and weathertightness.

Mounting system design should also consider roof loading, wind exposure and mechanical installation guidance, including relevant references such as BRE Digest 489, BRE Digest 495 and BS EN 1991-1-4.

For pitched roof solar mounting, the system must suit the roof covering, fixing points and supporting structure. Flat roof mounting systems require consideration of ballast or attachment method, membrane protection, row spacing and system orientation. For in-roof solar mounting, roof integration, weatherproofing and fire performance are particularly important.
