Why it matters

Faults you can't see
are costing you money.

Hot-cells, bypass diode failures and PID degradation are invisible to the naked eye, but thermal imaging reveals every one of them.

30%
of solar systems have at least one underperforming panel
UK energy research shows nearly a third of residential PV systems have a detectable thermal anomaly within 4 years of installation.
£300+
lost per year from a single faulty string
A confirmed hot-cell fault on one string can cost £280–£460 in lost yield annually, invisible to your inverter dashboard.
0
seconds of panel downtime during our inspection
The entire inspection is conducted from the ground using a DJI Matrice 4T. No roof access, no scaffolding, no disruption whatsoever.
What's in the report

Six sections.
Every angle covered.

Structured so your installer, insurer or energy assessor can act on it immediately, with no translation needed.

FAQ

Common questions

No. The entire inspection is conducted from the ground using thermal and RGB cameras on the DJI Matrice 4T. Your panels remain live throughout and the inspection typically takes under an hour from arrival to pack-down.
Thermal imaging reliably detects hot-cell faults, bypass diode failures, Potential Induced Degradation (PID), micro-cracks, shading anomalies and surface contamination hotspots, all invisible to standard inverter monitoring and visual inspection alone.
Your PDF inspection report is delivered within 24 hours of the inspection. It's structured to the standard expected by solar installers, energy assessors and insurers, so you can share it directly without any additional interpretation.
Thermal inspections require a minimum solar irradiance of around 600 W/m² to produce reliable data. We monitor conditions in advance and will rebook if the forecast is unsuitable. Our Weather Refund Guarantee means you're never out of pocket.
Yes. The report is specifically designed for this. It includes radiometric image data, severity-rated fault findings, yield impact calculations and prioritised recommendations in a format your installer or insurer can act on immediately.
