Why Thermal Inspections Matter
Early fault detection saves costs Thermal inspections detect issues like hotspots, cell degradation, and electrical faults before they escalate into expensive problems. When anomalies such as PID or microcracks are missed, they can grow over time, le
Understanding Delta T in Drone Thermography
Definition and Context Delta T (ΔT) is the temperature difference between an anomalous component and its surrounding nominal components. In solar thermography, this metric is critical for identifying irregularities in photovoltaic modules. Common ano
Drone Thermography vs. Traditional Testing — What Delivers Better Accuracy?
Electroluminescence (EL) testing and I-V curve tracing offer high accuracy but require module disconnection, high labour costs and system downtime. Drone thermography provides a rapid, non-invasive alternative capable of screening 100% of modules at
Detecting Microcracks, Hotspots and Junction Box Failures — Thermal Patterns Explained
Thermal anomalies appear in diverse patterns: single-cell hotspots, multi-cell degradation, diode failures, cracked modules and overheating junction boxes. We break down each pattern and show how high-resolution thermal imagery allows early fault cla
Using Drone Thermography To Identify PID
To grasp the value of using drone thermography for detecting PID, it’s crucial to contrast it with traditional methods, starting with the least effective: relying on production monitoring figures to detect PID’s effects.Generally speaking, PID manife
What Causes PID on PV Modules?
PID does not have a single root cause and can affect any crystalline-silicon or thin-film module, regardless of age, manufacture, operating conditions, or installation. However, factors known to increase the likelihood of PID include hot and humid op
