Rooftop Solar Thermal Inspections
Fitted & Forgotten – The Hidden Risk
Decreased Efficiency & ROI
Faulty panels can reduce system output significantly.
Increased Fire Risk
Hotspots and electrical faults may cause overheating.
Insurance Non-Compliance
Lack of inspection can invalidate coverage.
Field-Proven Thermal Data You Can Act On
We utilise industry-leading equipment, such as the DJI Enterprise series, equipped with high-resolution radiometric sensors. This allows us to measure temperatures on the spot and capture precise infrared imagery. We don’t just hand over raw data; we provide expert analysis so your maintenance teams can fix the exact problem in the exact location.
- Professional PDF report with annotated thermal and visual (RGB) images.
- Fault summary with clear severity grading (Critical, Moderate, Minor).
- Actionable maintenance and repair recommendations.
- Optional follow-up scan after remedial work is completed.

Frequently Asked Questions
Yes. For accurate thermal readings on buildings, an adequate temperature difference (Delta T) between the inside and outside is required, often meaning surveys are done early morning or late evening. For solar PV, we need sufficient solar irradiance (clear, sunny conditions) to ensure the panels are under load.
Absolutely. Drones capture the entire roof or solar array from the optimal angle without the operator standing on steep pitches or fragile surfaces. It provides a complete, uninterrupted view that handheld cameras struggle to achieve on large sites.
Costs vary based on the size of the building or solar array and the location. However, drone surveys are almost always significantly cheaper than arranging manual access. Contact us for a free, no-obligation quote tailored to your project.
