The Module Doctor PVD-10 is a solar panel inspection device that identifies defects in solar cells, such as those used in residential applications. It can locate the defects simply by searching the surface of the module's busbar electrodes with a special sensor. Previously, defective modules in a string had to be removed one by one for inspection, but with the use of the Module Doctor, defective modules can be identified without removal. For more details, please contact us.

The multifunctional PV tester PVCHECK complies with the maintenance inspection guidelines JEM-TR228 and JPEA guidelines in Japan, and is capable of measuring ground resistance (2-pole method), insulation resistance (measured with string short circuit), open circuit voltage, and short circuit current! For the open circuit voltage and short circuit current measurement functions, it displays the results of STC (Standard Test Conditions) calculations based on solar radiation and module temperature, and can determine pass or fail by comparing with a pre-registered module database. Furthermore, it can measure string current and its power as specified by the international standard IEC62446, allowing for easy evaluation of string performance in actual operating conditions on-site.

Solar power generation refers to a method of generating electricity by directly converting solar energy into electrical power using solar cells, and it is a type of renewable energy. Due to its low operational and maintenance costs as a clean energy source, demand is increasing globally. Currently, there are no regulations regarding the maintenance of solar panels, leading to issues such as uncertainty about whether they are generating power as specified. However, as the market is expected to expand in the future, it is anticipated that regulatory measures will also progress, making performance checks for solar power generation increasingly important. At Rex, we have gathered equipment to measure the performance of solar power generation. For more details, please download and view the catalog.

Currently, there is a growing global demand for solar power generation. At present, there are no legal regulations, and there are issues such as not knowing whether the power generation is being carried out correctly according to specifications. However, it is expected that legal regulations will advance with the expansion of the market, making performance checks for solar power generation increasingly important. At Rex, we handle equipment that measures the performance of solar power generation. ↓ For more details, click on "Rex Measurement Equipment Rental - Solar Power Measurement Instruments Homepage"!

Before installing a solar power generation system, it is possible to calculate the monthly and annual sunlight hours with a single shot. By using the built-in fisheye lens to capture the surroundings, the actual position of shadow occurrence can be identified, and the annual sunlight hours can be determined from the annual solar trajectory.

"PVCHECKs" is a measuring instrument that complies with the maintenance inspection guidelines JEM-TR228 and JPEA guidelines in Japan, capable of measuring ground resistance (2-pole method), insulation resistance (measured with string short-circuit), open circuit voltage, and short-circuit current. For the open circuit voltage and short-circuit current measurement functions, it displays the results of STC (Standard Test Conditions) calculations based on solar radiation and module temperature, and it can determine pass or fail by comparing with a pre-registered module database. Additionally, it is capable of measuring string current and power as specified by the international standard IEC62446, allowing for easy evaluation of string performance in actual operating conditions on-site. 【Features】 ■ Capable of insulation resistance, open circuit voltage, and short-circuit current testing ■ Complies with IEC-62446 ■ Can measure string DC power while connected to the PCS ■ Built-in automatic short-circuit function between P-N during insulation resistance testing ■ Enables STC evaluation of PV modules based on solar radiation and temperature measurements *For more details, please feel free to contact us.

The "I-V400w" is an I-V curve tracer that measures the current-voltage output characteristics for evaluating the performance of solar cells. Designed for easy portability at installation sites or factories where solar cells are inspected, it weighs only 1.2 kg and is handheld. The large LCD display, controlled by keys, allows for the selection of measurement menus and displays measurement results, with the ability to store 250 measurement data points in memory. 【Features】 ■ Compact and lightweight design that can be held with one hand ■ High precision measurement (±1%) ■ Ability to register the rated values of solar cells in a database for automatic pass/fail judgment on measurement data ■ I-V curves and various measurement data are clearly displayed on a large LCD ■ Capable of measuring the series resistance RS, which plays an important role in I-V curve measurement *For more details, please feel free to contact us.
