PV feasibility

On-site PV feasibility study

Before sizing a photovoltaic system, one question always comes first: does the site have enough solar potential to make the project worth pursuing?

A PV feasibility study assesses the main technical factors that will influence future production: shading, orientation, tilt, available area and solar potential.

Azimutis helps carry out this preliminary assessment directly on site from a horizon profile survey, with immediate shading analysis, production estimates and PDF report generation.

Why run a PV feasibility study?

A PV feasibility study quickly checks whether a project deserves to move forward into more detailed analysis.

It helps to:

  • identify obstacles that may reduce production
  • measure the real impact of shading
  • estimate the site’s energy potential
  • compare several layout assumptions
  • qualify a project before detailed engineering
  • bring objective technical data into the site visit

The earlier this assessment is performed, the easier it is to avoid unnecessary studies and weak assumptions.

Shading: a decisive feasibility factor

Trees, buildings, terrain or other obstacles can significantly reduce PV production.

Shading analysis is therefore a key step in a PV feasibility study.

Azimutis lets you capture a horizon profile directly in the field to represent the project environment accurately.

The captured data is then used to calculate:

  • shading losses
  • solar access
  • the most affected periods
  • corrected production estimates

This provides a more realistic view of the site’s potential than visual inspection alone.

From site visit to preliminary PV assessment

During a technical site visit, information is often spread across photos, notes, sketches and separate measurements.

Azimutis centralises these inputs in one tool so field data can become a usable preliminary PV assessment.

After the horizon profile survey, the app can help you:

  • view the sun-path diagram
  • analyse shading
  • estimate PV production
  • compare scenarios
  • generate a PDF report
  • export data to specialised software

The goal is to have an initial technical evaluation available immediately.

What are the limits of a PV feasibility study?

A full feasibility study may include many additional checks:

  • roof structure assessment
  • electrical grid connection
  • detailed economic analysis
  • regulatory constraints
  • administrative procedures

Azimutis focuses mainly on the on-site preliminary assessment linked to solar potential and shading.

The app provides technical data that helps assess project relevance before deeper studies begin.

Features used for PV feasibility assessment

To run a technical pre-assessment directly on site, Azimutis includes several tools:

  • horizon profile survey
  • shading analysis
  • solar access
  • PV production estimate
  • obstacle height simulation
  • comparative scenarios
  • roof measurement
  • installable power calculation
  • CSV, TXT and HOR exports
  • PDF report

These features give a fast overall view of a project’s solar potential.

Frequently asked questions

What is a PV feasibility study?

A PV feasibility study analyses the characteristics of a site to assess whether a solar project makes technical sense.

Why analyse shading?

Shading can reduce electricity production and affect the economics of a PV system. Analysing it provides a more realistic estimate of solar potential.

Can a feasibility study be carried out directly on site?

Yes. A preliminary PV assessment can be performed during the technical site visit to obtain an initial project evaluation quickly.

What is the difference between a preliminary assessment and a full study?

A preliminary assessment quickly qualifies a project from site characteristics. A full study usually includes more detailed structural, electrical, regulatory and economic analysis.

Conclusion

A project’s solar potential depends heavily on its real surroundings.

With horizon profile capture, shading analysis and production estimates, Azimutis helps perform a preliminary PV assessment directly on site and quickly gather the information needed to evaluate a project’s technical feasibility.
