Recently sold high-efficiency solar cells PVA14300R, PVA18340, PVA11270, and PVA14301 can be measured using I-V measurements.
In recent years, there have been reports of cases where I-V curves cannot be measured for high-efficiency solar cells (such as N-type and half-cut cells) using products from other companies or the old model Epsilon 1000 (PVA14300) PV analyzer. However, it is possible to measure them using the current Epsilon 1000 (PVA14300R), Epsilon 1500 (PVA18340), Gamma series (PVA11270, PVA14301), and Delta (PVA11272) PV analyzers, which will be explained in this document.

Company information
Since the time of the Sunshine Project at the current Ministry of Economy, Trade and Industry, we have developed simulated power sources, measuring instruments, power conditioners, and more, in response to requests from organizations such as the National Institute of Advanced Industrial Science and Technology, the Central Research Institute of Electric Power Industry, and Tokyo University of Agriculture and Technology. Based on these achievements, we have commercialized our products and expanded sales to various research institutes and manufacturers, proudly positioning ourselves as a niche leader in this field. We specialize in the development of products and systems that combine hardware and software, including simulated power sources such as solar cells and storage batteries, load devices necessary for grid connection testing, and testing systems that operate these components collectively. We also have extensive experience in solar cell measurement, and our I-V curve tracer is widely used not only for the maintenance of solar power plants but also for research and development purposes at manufacturers, research institutions, and universities. We have numerous delivery records of automated measurement systems that incorporate measuring instruments and load devices. Development of power electronics equipment that combines analog and digital technologies, development of control software using DSP, and construction of PV measurement systems are among the services we offer, tailored to meet our customers' needs.
