On-site assessment

On-site PV assessment with horizon profile survey

On-site PV assessments help teams qualify project feasibility, solar exposure, shading constraints and first PV sizing assumptions before detailed engineering. When shading matters, the horizon profile survey captures the field data needed to turn visible obstacles into a usable shading profile.

What an on-site PV assessment should validate

  • site shading level
  • overall solar exposure
  • solar irradiance potential
  • orientation
  • tilt
  • nearby obstacles
  • consistency of first technical assumptions

The objective is to build a usable first reading of the site before deeper analysis.

Solar irradiance analysis and PV potential

An on-site PV assessment is not only a theoretical production estimate. It connects site observations with orientation, tilt, shading constraints, solar access and visible field conditions.

Azimutis can be used as a field solar assessment tool to prepare a first reading of PV potential:

  • solar exposure qualification
  • shading analysis
  • clear-site or shaded-site workflow
  • initial production estimate
  • working base before detailed PV design

Preliminary solar design and PV system sizing

Azimutis supports the preliminary design stage by checking whether first project assumptions are consistent with the real site.

On site, the app helps structure useful inputs before detailed engineering:

  • usable area or roof zone
  • orientation and tilt
  • presence or absence of shading
  • initial solar potential
  • first technical and economic assumptions
  • PDF report or exports for downstream PV planning tools

The goal is not to replace detailed PV design software, but to improve the first analysis layer and reduce rework after the site survey.

With shading or no shading

Two operating modes can be used depending on site conditions.

With shading or shading uncertainty: use a horizon profile survey to better qualify obstacle impact.

Clear site: if no significant obstacle affects solar access, run the assessment without full profile capture.

This avoids applying the same analysis depth to every project.

What the assessment produces

  • first site qualification
  • concrete potential reading
  • initial shading impact estimate
  • base for further PV planning
  • decision support before detailed design
  • material for report and exports

On-site assessment vs office-only rework

  • document the site immediately
  • reduce post-visit omissions
  • limit re-entry
  • validate assumptions earlier
  • prepare the next engineering step better

This does not replace detailed planning, it improves the quality of the first analysis layer.

Outputs after the visit

  • in-app analysis
  • PDF report
  • site-data exports
  • working material for next study steps
  • internal or client discussion support

Business use cases

Useful for fast qualification before investing more engineering time, for both installers and engineering teams.

FAQ

What does an on-site PV assessment cover?

It covers first site qualification, shading level, solar potential, production estimate and assumptions useful before detailed PV design.

Can Azimutis be used for solar irradiance analysis?

Yes. Azimutis helps qualify solar exposure, shading constraints and site potential to prepare a first solar irradiance and PV production assessment.

Is Azimutis solar design software?

Azimutis supports preliminary PV design from the field, with site assessment, shading analysis, production estimates, PDF reports and exports for downstream planning tools.

Can Azimutis help with PV system sizing?

Azimutis helps with first PV system sizing assumptions by qualifying the site, usable area, orientation, tilt, shading and solar potential before detailed engineering.

Is it suitable for short visits?

Yes, if used for initial qualification and not full detailed design.

Is horizon profile capture always required?

No. Clear sites can start without full profile measurement.

What does the assessment actually produce?

It produces a first site qualification, a concrete reading of solar potential, initial shading impact estimates and material for reports or exports.
