Intelligent Aerial Thermography that Improves Operational Workflow, Safety and Profitability
RDT provides an end-to-end service from flight operations to artificial intelligence (AI) geo-referenced analytics and reports, utilising the latest developments in drone hardware and software. All our operations meet industry-standard safety and quality requirements.
Increase ROI by identifying anomalies that impact your PV system's performance. Whether you wish to identify module tilt tracking errors or conduct full-scale analysis in accordance with IEC TS 62446-3 technical specifications, we provide aerial solutions from preconstruction to commissioning and system maintenance.
Absolute temperature deltas combined with 1 cm/px resolution make it easier than ever to identify cell-level anomalies. Increase production and reduce operational costs using a platform that combines aerial inspection imagery into detailed analytics on asset condition and easy-to-use reports for asset management and work orders.
IEC TS 62446-3 — Photovoltaic Systems: Requirements for testing, documentation and maintenance. Outdoor infrared thermography: identification of defects with Class of Abnormality (CoA) 2 and 3.
AI software platform identifies and classifies anomalies at cell level — the highest resolution inspection available.
Machine learning accurately identifies PV system anomalies and prioritises them based on energy production loss and estimated financial impact.
Each PV system converted into a digital model incorporating critical structure and electrical data, geo-referenced to encode each module for easy ground-team location of anomalies.
Downloads available in PDF, CAD, CSV and printable composite site images. Reports designed for ground-team use and asset management workflows.
All pilots hold a Remote Pilot's Licence (RPL) and operate aircraft registered with SACAA, trained specifically in advanced solar aerial data collection.
From project development timelines and earthwork volumes to commissioning inspections and ongoing maintenance analysis — full lifecycle coverage.
Perimeter patrol and intrusion detection across array fields, with night thermal surveillance for panel theft and vandalism.
Pre- and post-cleaning validation using reflectance analysis, with soiling rate mapping to optimise contractor cleaning routes.
Project developments evaluated with visual timeline from multiple surveys, topographic orthomosaics and advanced analytics: earthwork volumes, beam sets, module counts, fencing and shadowing.
Guarantee the PV system is fully operational by identifying anomalies before demobilisation of engineering teams, ensuring they are rectified timeously.
Regular aerial inspections identify degradation, soiling and emerging faults before they cause significant production losses.
