Introduction
PV (Photovoltaic) systems are built to operate outdoors. Over time, aging of components can cause problems like loose wiring, cable deterioration, and localized heat accumulation known as "hot spots“. Such conditions reduce energy output, and if unnoticed, may lead to fire hazards.
Generally, periodical inspections are performed, but if a problem occurs between, it can delay discovery of the problem. And, inspections are often done visually or with thermal imaging, which can make it difficult to spot problems at an early stage.
Therefore, to improve safety and system longevity, PV installations of all sizes require a dependable way to detect heat-related issues early.
Solutions and Benefits
Localized temperature changes often occur in abnormal locations on equipment, not just in PV systems. Constant monitoring of these temperature changes will lead to early detection of abnormalities.
DTSX is a distributed temperature sensing system to monitor temperature across long distances at 1-meter intervals with optical fiber cables. It enables early detection of abnormal heating in panels, cables, and junction boxes -common failure points in PV systems.
Furthermore, by accumulating and analyzing the measured temperature data, it can also be used to manage maintenance history and analyze the causes of problems.
