Infrared (thermal) imaging can reveal hidden problems in a solar array. An infrared camera shows “heat differentials” between cells, which helps detect faults that the eye can’t seeinfraredtraining.com. For example, if one panel is overheating (a “hot spot”), the thermal image shows it as a bright spot. This can mean a failed cell or dirt shadow. Thermography is especially valuable for large systems, but even homeowners can use it occasionally.
- Detecting Faults: A thermal scan can find damaged or dirty cells. Faulty diodes or micro-cracks glow differently on a heatmap. Early detection means you can repair or replace panels before they fail completely.
- Warranty and Insurance: UK inspectors use thermal imaging for pre- or post-warranty checks. A certified thermal inspection before your warranty expires can document any hotspots or faulty cells while repairs are still coveredthermographyservices.co.uk. Similarly, after a storm, it can verify damage for insurance claims.
- When to Get a Scan: For small domestic systems, an annual cleaning usually suffices. But if you notice unusual behavior (like one panel underperforming), a thermal check is wise. Some UK firms even offer drone-assisted thermal surveys to pinpoint problems efficiently.

In summary, while not mandatory for every homeowner, thermal imaging is a powerful diagnostic tool. Thermography experts point out that these inspections are invaluable for spotting issues earlyinfraredtraining.cominfraredtraining.com. To protect your system, consider scheduling a thermal survey if your installer offers it. This adds an extra layer of assurance that your panels are truly in top condition.
Call to Action: Protect your investment with a full inspection. UKSPCA members can often arrange thermal imaging as part of an inspection service. Use Find a Cleaner to locate professionals offering comprehensive panel checks.
