Solar panels are built to last, but that doesn’t mean they keep performing at their best. Especially older installations (10+ years) are more likely to suffer from hidden defects, reduced output, or even safety issues. A thermal drone inspection offers a fast and safe way to detect these problems.
Older panels: weak or missing bypass diodes
Modern solar panels come with bypass diodes that help redirect current around faulty cells or zones. But older panels — often pre-2010 — don’t always have them, or they no longer function properly.
-
Some panels have no bypass diodes at all.
-
Others have cheap or damaged diodes after years of use.
-
Some were poorly designed, so the diode doesn’t activate as it should.
Preparation: clarity from the start
FPV stands for First Person View and means that, as a drone pilot, you receive live images directly from the drone’s camera. In the early days, this usually happened via an analog video link, with a small transmitter on the drone and a receiver built into the goggles or monitor. This way, you experience the flight as if you are inside the drone – something drone enthusiasts describe as a unique, almost bird-like sensation. Although technology has advanced enormously since then, the core feeling remains the same: flying in real time through the eyes of your aircraft.
