Complete Solutions for Solar Energy Asset Management

From Prospecting to Predictive Maintenance: Optimize the complete lifecycle of your solar assets.

Intelligent Management of Photovoltaic Assets

Aerial Inspection and Ground Components

In the current scenario of expansion of the renewable energy matrix, the Operation and Maintenance (O&M) of Photovoltaic Plants (PV Plants) requires a comprehensive approach.

Traditional manual inspection alone has become insufficient. To ensure maximum performance and operational safety, it is imperative to monitor not only the solar panels, but the entire energy conversion and distribution infrastructure.

DRONE & GIS's technological solution is Hybrid Inspection, which integrates the macro and rapid vision of Unmanned Aerial Vehicles (DRONES) with the detailed precision of terrestrial thermography in ground components (BoS – Balance of System), all unified by Artificial Intelligence and GIS.

Methodology: The Hybrid Approach

Our methodology combines two data acquisition approaches to cover 100% of the plant's assets:

Air Inspection
(Scalability and Precision)

Execution of automated flights with hybrid payloads (high-resolution RGB sensors and Radiometric Thermal sensors). This approach ensures massive scanning of the solar field, identifying thermal anomalies with precision at the cell and string level.
Land Inspection (Detail and Depth)

Instrumental inspection performed by certified technicians using highly sensitive handheld thermal imagers. The focus is on the critical analysis of the Balance of System (BoS), diagnosing internal components of inverters, string boxes, and connections hidden from aerial view.

Data Fusion (Digital Ecosystem):

Systemic integration of data layers (aerial and terrestrial) processed by Computer Vision algorithms. The result is the consolidation of all information into a single geospatial platform, generating a navigable and auditable Digital Twin of the power plant.

Engineering Solutions and Asset Performance

At DRONE & GIS, we unify precision engineering and data intelligence to maximize the lifecycle of your energy infrastructure. Our approach integrates drones, geotechnologies, and AI to deliver in-depth diagnostics on solar generation assets. From topographic surveys and engineering project support to predictive inspection focused on O&M, we transform asset management into an exact science, ensuring operational safety, regulatory compliance, and maximum revenue recovery.

Pre-Construction Phase: Advanced Topography and Layout Optimization

Prior to installation, the accuracy of the terrain model is crucial for calculating earthworks (cut and fill) and for analyzing shading.

High-Density Planimetric and Altimetric SurveyWe generate high-density point clouds, enabling the creation of Digital Terrain Models with centimeter-level precision. This is crucial for drainage projects and for ensuring that the terrain slope is compatible with the limits of solar trackers.

Analysis of Obstructions and ShadingUsing the Digital Surface Model, we map not only the ground, but all obstructions above it (trees, power lines, buildings). This data feeds simulation software to design the layout with the lowest possible shading index, maximizing energy yield.

After construction, aerial photogrammetry takes on a new and critical role: it becomes the visual reference layer for thermographic inspection and asset management.

Ultra-Resolution RGB OrthomosaicWe produced a continuous, georeferenced, high-precision visual map of the entire plant. This map allows visualization of physical details such as serial numbers (when visible), fence integrity, soil erosion, and the physical condition of the modules.

Contextualization of Thermographic InspectionThermal imaging shows where there is heat, but not always what the fault is. By overlaying the thermal layer onto the high-precision RGB orthomosaic, our analysts and AI algorithms can distinguish a real hotspot (electrical fault) from a false positive caused by dirt (bird soiling) or vegetation shadows.

Automatically identify and classify critical pathologies:

Hotspots

Detection of severe thermal dissipation caused by microcracks, snail trails, or localized shading, preventing irreversible damage to the backsheet and fire hazards.

Bypass Diodes (Activated/Defective)

Identification of characteristic heating in junction boxes, indicating the inoperability of sub-strings (loss of 1/3 of the module's power).

Disconnected Strings

Precise location of entire inoperative series due to blown fuses, open connectors, or inverter faults, invisible to visual inspection.

Potential Induced Degradation

Recognition of geometric thermal patterns (checkerboard or edge effect) associated with potential-induced degradation, allowing for early corrective actions.

Ground Inspection of Soil Components and BoS (Balance of System)

While aerial inspection focuses on energy capture, ground inspection ensures the
integrity of the conversion and flow of this power. This step is crucial for the
operational safety, focusing on the early detection of thermal anomalies that
