Every Utility-Scale offering

Each one has its own page with the full detail.

Plan, build, operate

Keep scrolling. The site moves through its life.

Plan, build and operate against the same spatial record, so the as-built is a byproduct of the work, not a separate project.

01

Plan: LiDAR topography

Terrain capture before earthwork commits you to a number. Grading volumes, drainage paths and racking layout off measured ground.

02

Build: construction monitoring

Repeat flights through the build. Installed rows counted against the plan set, deviations flagged while they are still cheap.

03

Operate: thermal & EL

Full-array thermal and electroluminescence, every string not a sample, with module-level defect location.

You can only manage what you can actually see

At a thousand acres, walking the array is not a plan. A two-person crew with a clipboard covers a fraction of a percent of the modules in a day, and whatever they do not reach is assumed healthy. Most utility-scale underperformance is not a mystery, it is unmeasured.

1

Terrain drives the design

Grading, drainage and slope decide pile depth, tracker row geometry and how much earthwork the project carries. Getting it from imagery is how budgets move after financial close.

2

Defects compound quietly

A string out at 2% loss is invisible in monthly production data and obvious in a thermal orthomosaic. Across a year it is real revenue.

3

Warranty windows close

Module defects are recoverable while the warranty is live and yours forever after. A commissioning baseline is what makes a claim provable.

What we run at scale

Pre-construction

Boundary and topographic survey of the site, with LiDAR-derived terrain where the ground warrants it. Slope, drainage and access captured for the civil design rather than estimated. Detail on the land surveying page.

Construction monitoring

Periodic aerial capture across the build, so progress, pile placement and tracker alignment are measured against the design instead of reported against it.

Commissioning baseline

Full-array aerial thermal and electroluminescence at energisation. Every module inspected, not a sample. This is the document that makes a warranty claim provable, and the point at which defects are still the EPC's to fix.

Operating inspection

Recurring thermal and electroluminescence sweeps with module-level defect classification and location, so O&M gets a work order rather than a heat map. More on inspection.

What comes back

Survey and terrain

  • Boundary and topographic survey
  • LiDAR-derived terrain model where the ground warrants it
  • Slope and drainage analysis
  • Access routes and laydown areas
  • Existing easements and encroachments, located
  • Geolocated orthomosaic of the site

Inspection output

  • Full-array thermal orthomosaic, every module
  • Electroluminescence for cell-level cracking
  • Defect classification by type and severity
  • Module-level location, down to the row and position
  • Tracker and row alignment against design
  • Comparison against the commissioning baseline

One capture standard, every scale

The discipline that makes a 1,800 square foot roof survey repeatable is the same one that makes a 40-acre field repeatable: the capture is a fixed spec, so the failure mode is not a bad image but a missing measurement, and a spec removes it. Nationwide, across more than 50,000 surveys and seven years.
