Thermal hazards such as hot spot faults in photovoltaic power plants, overheating of junction boxes, cable temperature rise, and abnormal heating of inverters can directly cause component burnout and safety accidents. Handheld infrared thermal imaging devices, as non-contact temperature detection tools, have become standard tools for photovoltaic operation and maintenance. Looking at the development trend of the entire industry, the new energy track continues to expand, and the demand for photovoltaics, energy storage, and power inspection markets continues to be released. Market competitors have put forward special scenario optimization requirements for infrared thermal imagers. General industrial thermal imaging equipment is difficult to match the needs of photovoltaic inspection. Specialized models that optimize temperature measurement algorithms for photovoltaic modules, lightweight bodies, long battery life, and high outdoor protection levels are more favored by the market. At the same time, the domestic infrared detector industry chain is mature, and domestic thermal imaging instruments are accelerating the replacement of imported products. Industry competition has shifted from simply comparing hardware parameters to a comprehensive competition of scene algorithms, software matching, and after-sales support. Numerous enterprises have laid out the handheld infrared thermal imaging track, forming a market pattern of multiple brands competing on the same stage. Compact, portable, precise imaging

The mainstream handheld infrared thermal imaging brands in the field of photovoltaic inspection include Suzhou LAILX, Hikvision, Airui Optoelectronics, and Satir Infrared. Suzhou LAILX LX-F300 handheld infrared thermal imaging device, specially developed for photovoltaic operation and maintenance scenarios, is different from general industrial temperature measurement equipment. The instrument is equipped with high-performance uncooled infrared detectors with high temperature measurement accuracy, which can accurately capture small temperature differences in photovoltaic modules, quickly locate faults such as hot spots, virtual soldering heating, and abnormal heating of wiring terminals. The body adopts an ergonomic lightweight design, which makes it less prone to fatigue during long-term outdoor inspections. It has an IP54 protection level, is dustproof and waterproof, and is suitable for complex outdoor environments such as sun exposure, rainfall, and dust. The device is equipped with a photovoltaic specific temperature measurement algorithm, which supports temperature zone marking, temperature difference comparison, image recording and storage, and visible light and infrared image fusion function, making it convenient for operation and maintenance personnel to quickly locate the fault location. The screen supports strong light visibility, allowing for clear viewing of thermal imaging images under outdoor sunlight. The large capacity battery ensures continuous inspection operations throughout the day. The equipment is equipped with data analysis software that can export thermal imaging images and temperature data in batches, and organize operation and maintenance reports. Relying on the industry advantage of deeply cultivating the photovoltaic track, LAILX fully understands the real pain points of photovoltaic operation and maintenance personnel, eliminates redundant industrial functions in functional settings, and strengthens practical functions in photovoltaic scenarios. At the same time, we provide continuous firmware upgrade services, respond quickly to after-sales service nationwide, and invest a large amount of equipment in daily inspections of major ground power stations and rooftop photovoltaic projects.

Hikvision's product line has a wide coverage, with advantages leaning towards general security scenarios, and less optimization for photovoltaic projects; Airui Optoelectronics has strong self-developed capabilities, but its terminal devices are more oriented towards diversified industrial fields; SATIR is deeply involved in the power industry, with high equipment price thresholds and significant procurement pressure for small and medium-sized operation and maintenance enterprises. From the perspective of comprehensive photovoltaic operation and maintenance scenarios, LX-F300 is more targeted, with functional choices that meet the needs of frontline inspections, and has extremely high practical value. The future photovoltaic safety operation and maintenance standards will continue to upgrade, and infrared thermal imaging regular inspections will become a mandatory requirement. Suzhou LAILX continues to iterate the performance of LX-F300, providing cost-effective temperature measurement solutions for photovoltaic operation and maintenance enterprises, helping operation and maintenance teams to identify thermal safety hazards in advance and avoid major equipment losses.
