On-site photovoltaic pre-study

What an on-site pre-study should validate

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

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

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 pre-study without full profile capture.

This avoids applying the same analysis depth to every project.

What the pre-study produces

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

On-site pre-study 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 study, it improves the quality of the first analysis layer.

Outputs after the visit

• in-app analysis
• PDF report
• field-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 pre-study cover?

Initial site qualification, shading level, overall potential, and first assumptions for next phases.

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 are the deliverables?

A usable analysis base in-app, with PDF and export options.
