📸 SPOTTED FROM THE AIR: What your solar panels are hiding! 🔍🛰️
I recently completed a drone-based thermal imaging inspection on a domestic solar array, and the results perfectly highlight why thermal tech is a game-changer for solar maintenance.
To the naked eye, these panels looked completely normal. But when we view them with an infrared lens, a completely different story is revealed.
Here's what was uncovered on this single job:
1️⃣ A completely bypassed internal circuit: One panel had an entire horizontal section completely overheating (registering a major temperature spike) due to a failed internal component. This single fault instantly knocks out roughly 33% of that panel's power output!
2️⃣ Extreme Hot Spots: On another part of the roof, a localised hot spot soaring to nearly 100°C along a shadow line. At those temperatures, you aren't just losing efficiency - you are risking permanent panel damage and serious electrical hazards.
3️⃣ Heavy Algae & Bird Soiling: The thermal camera also clearly picked up heat blocks caused by built-up green algae and bird drop fouling along the bottom edges, which acts like a blanket and suffocates the cells.
⚠️ The takeaway? If your solar generation has dropped, or if your panels haven't been checked in a few years, visual inspections simply aren't enough. Many of these high-severity electrical faults are invisible until the panel completely fails - or worse.
Regular thermal drone surveys catch these issues early, protecting your investment, keeping your home safe, and ensuring you get every single kilowatt you paid for.
