Engineering on the building as measured.

Array layout, structural and electrical engineering off what was verified on site, not a set drawn in 1997. Stamped by a licensed professional engineer, permit-ready six days from the survey.

The drawings you inherit are rarely the building

Renovations, re-roofs and tenant changes pile up. Designing off old drawings is how an attachment lands on a joist that is not there.

1

Old drawings

As-built sets drift from the real building over decades. The survey is the correction.

2

Load margins

Commercial roofs often carry little spare capacity. Real joist depth and deck gauge decide what the roof can take.

3

Interconnection

Bus capacity and the interconnection path decide the system size as much as the roof does.

What comes back

A design and a stamped set built on one measured record.

Design

  • Array layout on the measured roof
  • Setbacks, fire pathways and roof access applied
  • Penetrations, curbs and drainage respected
  • Layout against the membrane and warranty constraints

Engineering

  • Structural analysis on real joist depth, spacing and span
  • Attachment design landed on the framing
  • Electrical engineering to the verified switchgear
  • Permit set sealed by a licensed professional engineer

How it works
