On-site assessment

From shading survey to a complete PV assessment

Survey shading and assess the PV project during the site visit: shading losses, production, module layout, self-consumption and financial returns with or without battery storage. Work on the same study in the mobile app and web portal, with synchronised project data.

1. Record the project conditions

Set the location, orientation and tilt, then define the usable surface and its obstacles. Where shading matters, capture a horizon profile and review PV shading analysis and loss estimates. Height simulation also lets you assess shading at roof height from a ground-level survey, without climbing onto the roof.

2. Compare module layouts and installable capacity

Place modules within the usable surface, allowing for obstacles and margins. Compare portrait and landscape layouts and review the resulting installable PV capacity. Record the module and capacity assumptions used for the study.

3. Review hourly PV production

Estimate PV production using the project parameters and shading profile. Inspect the production results and shading losses before using them in the consumption and economic analysis.

Duplicate the project to compare configurations while keeping the assumptions for each variant explicit.

Hourly results and their assumptions can also support the technical review of a PV financing application.

4. Analyse self-consumption and battery storage

Use a consumption profile to estimate how much PV energy is consumed on site and how much is exported. Review the estimated savings using the chosen energy prices.

Compare PV alone with PV and battery storage. Battery parameters include minimum state of charge, charge and discharge losses, cost and replacement assumptions. Review the impact on self-consumption and economic indicators.

Use the results to discuss project choices

Explain the estimated production, shading impact and self-consumption to the customer. Compare the consequences of a different layout or battery configuration using the same baseline assumptions.

For the wider checks needed before proceeding, see the PV feasibility assessment.

Frequently asked questions

What does an on-site PV assessment cover?

Azimutis combines field measurements, shading analysis, hourly production estimates, module layout, installable capacity, self-consumption, battery analysis and economic indicators in a PV study.

Can I compare different configurations?

Yes. Duplicate a project to compare alternative layouts, orientations, capacities or battery assumptions. Review each variant with its own inputs and results.

Can I prepare the study before the visit?

Yes. Create and prepare the project in the web portal, synchronise it with the mobile app and add the field measurements during the visit.

What still needs separate verification?

Structural suitability, electrical design, grid connection and regulatory requirements need their own checks. Production and economic results remain estimates based on the selected inputs.
