EKO I-V tracers (MP-160 / MP-11 / MP-180) can be used in three different Power ranges. The research type MP-160 is an all round instrument to be used with single cells and modules or multiple unitswhen connected to the multi channels selectors. The portable MP-11 with remote sensor unit can be used on site to accurately check the performance of Modules and Strings. The high end MP-180 is capable to make high precision I-V measurements of small and large size solar cells and is most suitable for Research and Development applications or production inspection purposes indoors.
EKO has more than 15 years experience with respect to PV cell, module and array evaluation. Based on this considerable experience, EKO successfully completed a range of turn key I-V Curve Tracers, which can measure all types of PV cell and module technologies. Besides we continuously extend the capabilities of our product range by expanding functionality and new product development.
To measure I-V characteristics of solar Cells, Modules or Strings (Modules in series) it is important to match the measurable output power, respectively output Voltage and Current with the measurement device. The Product Power range diagram indicates the specific power range of the three EKO Instruments I-V curve tracers and helps to define the most suitable product for the application.

During the last decade Silicon PV cells (solar cells, the synonym for the PV cell) have been put to large scale production. Cell performance and module efficiency improved rapidly, larger sized cells have been adopted and the overall production costs dropped significantly. Still extensive research effort leads to new innovations like Compound Semiconductor and Dye-sensitized Solar Cells - which may very well become the next generation PV cell technology.
When did our PV activities start? In 1987, in conjunction with the Electro Technical Laboratory, now called National Institute of Advanced Industrial Science and Technology, we developed the first in EKO called "Condenser Load Method I-V Curve Tracer" which was used for measuring I-V characteristics of large outdoor solar power systems. Since then, we have been delivering our measurement instruments world wide to many customers working in national research institutes, PV technology development industry and in a later stage to module manufacturers, installers, service and maintenance engineers.
As a consequence of the since 1994 active Japanese directive to monitor or check the efficiency of PV power systems, the number of new residential PV power systems rapidly increased. For this purpose EKO developed a compact and light weight "I-V Checker" for installation checks and periodical maintenance. After the introduction in 1998 the product is still used by many of our customers in PV power systems industry.
In 2000, EKO took part in the called "Field Test Project" of the New Energy and Industrial Technology Development Organization (NEDO) and developed a PV Measurement/data logging System "PV Scanner" which was capable to measure and store valuable PV power system performance data. Nowadays EKO still supports the activity by collecting valuable test data, such as the PV system energy yield all over Japan.
In 2001, by combining proven technologies, EKO developed the next generation "Electric Load Method I-V Curve Tracer" called MP-160, which not only works with silicon type cells, but also compounds type cells and dye-sensitized cells.
For the first time in Japan, with the 2006 introduction of the MP-170 I-V checker, EKO enabled users to perform I-V measurement at 1000V and combining advanced measurement functions with the integrated sensor unit for hands on outdoor practice.
With EKO's current level of know-how and latest technologies used in Photovoltaic measuring equipment and Solar Radiation Sensors we aim to extend your measurement capabilities in function, accuracy and quality by offering innovative products and turn key systems such as I-V tracers, for Indoors cells valuation, Quantum yield measurement and outdoors evaluation of single modules and PV Power systems.
