Solar Structural Survey

If the installation is on an existing building then it must be strong enough to support the solar panels and mounting frame.  The roofing material must be safe to work upon and strong enough to secure the mounting frame.  This requires a full structural survey.

Most modern steel framed commercial structures are well within the limits to support a solar array so this should be a formality.

A typical solar array on a mounting frame will weigh around 13Kg/m2. This is well within most tolerance limits.
