01 / POSITIONING

More than imagery.
Usable technical evidence.

We support owners, installers, EPCs and O&M teams with asset documentation. Before mobilisation, we define objectives, area, access and expected data; during capture, we check coverage and quality; in delivery, we make findings clear and traceable. The drone is a tool: results depend on the agreed scope and site conditions.

02 / PHOTOVOLTAIC

GREEN ENERGY INSPECTIONS

A clear reading
of your plant.

UAS-assisted RGB and thermographic acquisition to locate indicators for verification and organise targeted follow-up. Activities are planned for the site, environmental conditions, access and criteria agreed with the client.

Discuss your plant
01

RGB and thermal acquisition

Aerial survey planned for coverage, resolution, irradiance and environmental conditions. Thermal images are interpreted as indicators for verification, not as an electrical diagnosis.

02

Located findings

Images linked to position references and a map of points for follow-up checks. Where available, plant layouts and string identifiers help improve location detail.

03

Documented report

Summary of findings, selected images and follow-up references. Format, detail level and map references are agreed before the assignment.

TECHNICAL SCOPE

The survey documents observable visual and thermal indicators and can support the technical team in planning further checks. It does not replace electrical diagnosis, field testing or assessment by qualified personnel, and does not independently certify plant performance. Reference to IEC TS 62446-3 is assessed against the purpose and conditions of the assignment; it does not imply service accreditation or certification.

03 / SURVEY EXAMPLES

Real imagery
from field work.

A selection of field captures and outputs: RGB images, thermograms, a 3D model and an orthomosaic. Coverage, accuracy and format are defined for each project based on its objective, site and operating conditions.

04 / SERVICE AREAS

Services defined
for the asset objective.

01 PV

Photovoltaic inspection

RGB and thermal capture, selection and location of findings. Documentation for monitoring, maintenance and re-inspection within an agreed scope.

02 ROOF

Visual roof inspection

Aerial documentation of roofs and visible components: coverings, protrusions, eaves and areas of interest. Orthophoto or 3D model when requested and suitable.

03 BUILD

Progress and as-built

Repeatable captures to document work progress, installation and site changes; time comparisons subject to available data.

04 WIND

Energy assets and infrastructure

Aerial visual surveys of selected components and energy infrastructure to record observable conditions and identify areas for further assessment.

ORTHOMOSAIC · SURVEY EXAMPLE
FOCUS / ROOFS

A clear visual record
with located detail.

UAS capture can document roof areas that are difficult to view from the ground and organise images by area or feature. Depending on size, access, lighting and flight conditions, delivery may include selected photographs, an orthomosaic and, if included in scope, a 3D model.

  • Residential, industrial and ancillary roofs accessible to survey
  • Visual documentation of surfaces, discontinuities and visible components
  • Visual references for site visits, maintenance and comparison over time

Survey limit: this is an aerial visual inspection. It does not certify water-tightness, waterproofing or structural safety and does not replace a close technical inspection.

05 / METHOD

From brief to report.
Clear at every stage.

01

Define

Objective, access, area, conditions and deliverable criteria.

02

Plan

UAS profile, image plan and resolution matched to the site and objective.

03

Survey and review

Capture, coverage review and checks for sharpness, completeness and data consistency.

04

Deliver

Selected images, location references and a report in the format defined at briefing.

06 / DELIVERABLES

Data prepared
for the next task.

Delivery is not a fixed package: it is sized to the issue, the site and the systems already used by the client.

IMAGESSelected RGB and thermal images, organised by area, date or feature.
LOCATIONReferences and a findings map, subject to available base data.
DERIVED OUTPUTSOrthomosaic or 3D model when requested and technically suitable.
REPORTDescriptive summary, referenced images and agreed observations.
07 / UAS QUALIFICATIONS

UAS competence.
Credentials stated precisely.

Giovanni Lucenti · remote pilot and UAS operator registered with D-Flight.

A1/A3 AND A2

Competency certificates for Open category A1/A3 and A2.

STS-01 · PRACTICAL PART

Practical part completed. Theoretical exam pending; the full STS-01 qualification has not yet been obtained.

CRM AND AERONAUTICAL COMMUNICATIONS

Crew Resource Management and aeronautical communications training completed.

The operating category, UAS and required authorisations are checked for each assignment.

08 / CONTACT

Let’s define your
next survey.

To prepare a proposal, tell us the location, asset type, area or capacity, objective, access and timing. For PV, include a layout, site plan and operating status if available; for a roof, tell us the covering type and areas to document.
