Solar Structural Letters

Nearly every solar installation needs a licensed engineer to certify that the structure can carry the array. It is repeatable, well-defined work, and the thing installers most need is a fast, reliable turnaround that does not hold up the job.

Scope

• Rooftop structural capacity analysis
• Sealed structural letters for permit submission
• Dead load, wind uplift and snow load evaluation
• Rafter, truss and connection assessment
• Ground-mount foundation design
• Reinforcement design where capacity is short
• Battery and equipment mounting certification
