SERIS provides thermographic analysis for photovoltaic (PV) systems at both the system and component levels, allowing early detection of thermal stresses that may indicate underlying issues. Thermal anomalies can compromise system performance or present safety risks, making regular thermographic assessments an essential part of PV system quality assurance.
Our analysis typically focuses on the following areas:
• PV string and module temperature measurements: By monitoring temperature across PV strings and individual modules, we can identify damaged modules, faulty solar cells, or overheating junction boxes, which may reduce energy yield or signal developing failures.
• Component temperature measurements: Elevated temperatures in components can lead to system downtime and pose fire hazards. Thermographic analysis evaluates the operating temperatures of key components, from DC field junction boxes to AC distribution boards, ensuring proper fuse ratings, component selection, and thermal management.
• DC and AC cable temperature monitoring: Hot spots can occur in exposed system elements as well as wiring. Causes include loose connectors, undersized cables, overloaded trays, improper cable routing, or AC cables entering switchgear incorrectly. Detecting these hotspots helps prevent performance losses and mitigate fire risks before they escalate.
Through comprehensive thermographic assessment, SERIS helps PV system owners and operators identify hidden faults, optimise performance, and enhance safety, ensuring reliable and long-term operation of solar assets.
