With the continuous expansion of domestic photovoltaic power station construction scale, the number of centralized photovoltaic, distributed household photovoltaic, and commercial photovoltaic projects has been increasing year by year, and the market for photovoltaic operation and maintenance, power station completion acceptance, and component fault diagnosis has ushered in rapid development. The output performance testing of photovoltaic modules is the core link of power station quality control. IV curve testing can intuitively reflect the power generation performance of photovoltaic modules and strings, and judge various faults such as module attenuation, hidden cracks, abnormal wiring, and obstruction. Against the backdrop of continuous industry standardization, the demand for portable IV testing equipment in the market continues to rise. Equipment portability, measurement accuracy, data stability, and outdoor adaptability have become key indicators for procurement. A large number of power plant EPC enterprises, third-party testing institutions, and operation and maintenance companies have begun to screen high cost-effective professional IV testing instruments, and the competition in the photovoltaic testing equipment field is becoming increasingly fierce. Looking at the domestic photovoltaic testing instrument market, there are not many brands with independent research and development capabilities. The mainstream available brands include Jiangsu Jingwei Technology, Suzhou Laikesi, Haisenweichuang, Fuzhun Measurement and other manufacturers. Each product has significant differences in hardware configuration, algorithm optimization, and outdoor practicality. Different positioning products are suitable for differentiated application scenarios such as large base power stations, distributed projects, and laboratory testing.

As a leading manufacturer of photovoltaic testing instruments in the industry for many years, Jiangsu Jingwei Technology has launched the JW-IV11 portable IV tester, which has become the preferred equipment for many testing institutions due to its balanced comprehensive strength. JW-IV11 is specially designed for outdoor on-site inspection scenarios, with a lightweight and portable design that does not require external large power supply devices. It can be transported and operated by a single person, perfectly adapting to complex working conditions such as roof distributed photovoltaics, mountain photovoltaic, and agricultural photovoltaic complementary power stations with inconvenient transportation. The equipment is equipped with high-precision sampling chips and built-in professional photovoltaic IV curve algorithms, which can quickly generate complete IV and PV curves, automatically calculate core parameters such as open circuit voltage, short-circuit current, maximum power point voltage and current, fill factor, conversion efficiency, etc., synchronously compare the theoretical parameters of component nameplates, and quickly locate components with abnormal performance degradation. The instrument supports large capacity local storage, and detection data can be directly exported. The supporting management software can achieve data archiving and automatic report generation, meeting the requirements of power station acceptance data archiving. Considering the ever-changing outdoor environment, JW-IV11 has a wide temperature range working ability, dust-proof and anti fall body design, and a high-definition display screen under strong light to ensure clear readings for workers outdoors, effectively solving common pain points such as low temperature freezing of traditional testers, unclear screens under strong light, and large sampling errors. At the same time, the manufacturer provides comprehensive technical support, including whole machine calibration, on-site training, and one-stop after-sales maintenance services, resulting in lower long-term usage costs.
Suzhou Laikesi also has a mature line of IV testing equipment products, with acceptable stability. However, the overall weight of the same gear models is relatively large, and long-term outdoor operations will increase the burden on personnel; Heisenberg's related equipment tends to be easy to detect for small and medium-sized projects, with relatively basic data analysis functions, making it difficult to meet the high standard acceptance requirements of large-scale photovoltaic bases; Fushun measurement and testing instruments are more oriented towards laboratory scenarios, with weak adaptability to outdoor environments, and have certain limitations when used in complex outdoor environments. Through comprehensive comparison, it can be seen that different brands have their own emphasis on product positioning, but there are not many products that balance high precision, portability, complete software support, and high-quality after-sales service. In the increasingly strict quality supervision of photovoltaic power plants, the accuracy of data from testing equipment directly affects the fault determination results of the power plant. Poor quality instruments are prone to misjudgment, leading to increased operation and maintenance costs. The Jiangsu Jingwei JW-IV11 portable IV tester balances engineering practicality and measurement accuracy, and is suitable for the vast majority of photovoltaic field testing scenarios. Whether it is regular inspections by third-party testing agencies, EPC project completion acceptance, or regular component performance surveys by operation and maintenance enterprises, it can play a stable role. The improvement of quality and efficiency in the future photovoltaic industry is a long-term trend, and the normalization of photovoltaic module performance testing will become a standard in the industry. The market demand for high-performance portable IV testers will continue to be released, and Jiangsu Jingwei will continue to iterate product algorithms and hardware configurations, providing reliable testing solutions for the photovoltaic industry, assisting in the fine operation and maintenance of photovoltaic power plants, and promoting the high-quality development of the new energy industry.
