For installers & EPCs

One field visit. Everything else comes off it.

Surveys, land surveying, inspection, stamped permit packages and shading analysis, delivered to your own client portal. Residential through utility-scale, nationwide, on one capture standard.

One field visit. Everything downstream comes off it.

Every service below starts the same way: a trained technician physically on the site, capturing structure and electrical in a single trip. What changes is the scale of the ground and what gets built from the data.

1

Residential

Rooftop PV at volume. Speed and repeatability decide the margin. Surveys, plan sets and permits, per site.

2

Commercial & Industrial

Big roofs, real structural risk, and coordination across trades. Assessment, engineering and the inspection work that keeps it producing.

3

Utility-Scale

Thousands of acres. You can only manage what you can actually see. LiDAR, monitoring, thermal and electroluminescence.

By service

Most customers use two or three of these together.

Field capture

  • Solar site surveys, roof and electrical in one visit
  • Land surveying, boundary and topographic work for ground-mount and utility-scale sites
  • Inspection, aerial thermal and electroluminescence on operating assets

Engineering and documentation

  • Permit packages, structural and electrical, stamped and sealed by a licensed professional engineer
  • 3D roof models accurate to less than an inch
  • Plan sets, permit-ready six days from the survey

Data and analysis

  • Client portal, every delivered survey with photos sorted, mapped and ready to share
  • Shading analysis, solar access, TOF and TSRF for each roof section
  • 3D roof measurement from the drone capture, every number shown with its tolerance

Coming soon

  • Remote shade reports before anyone drives out
  • Production estimates with P50 / P90 ranges
  • Performance monitoring once the system is energized

Why one vendor for all of it

The handoffs are where projects lose time, and they are the part nobody prices.

1

The survey feeds the plan set

When the same capture spec produces both, there is nothing to chase. That is why permit-ready lands six days from the survey instead of after two revision cycles.

2

One capture standard

Same checklist on a 1,800 square foot roof and a 40-acre field. The failure mode is a missing measurement, not a bad photograph, and a spec removes it.

3

Coverage without hiring

Nationwide, over more than 50,000 surveys and seven years. Your volume can triple in a metro without you adding a truck.

Work out whether it pays for you

We publish the arithmetic rather than asking you to take our word for it. The Field Notes series builds the in-house cost per survey line by line, with editable models, and shows where the crossover against outsourcing actually sits.
