Case Study: "Outdoor Exposure Measurement System with Remote Monitoring Function for Solar Cells" PDF

In a self-consumption solar power generation system with multiple strings, during the day, one I-V curve tracer will switch between the target modules to measure the I-V curve, and at night, one PV remote monitoring device will evaluate the bypass diode, blocking diode, and insulation resistance.

Automatically detects the occurrence of "solar cell malfunctions" and "DC ground fault incidents" that lead to fire accidents in solar power generation systems, serving as a safety net!

In solar power generation systems, there is a risk of fire accidents caused by factors such as leakage current and failures of bypass diodes in solar cells. To detect these issues, manual inspection work using devices like megohmmeters and bypass diode testing equipment is necessary. However, this device automatically performs these inspection tasks. It captures changes in conditions that are difficult to detect through monitoring measurement values via power conditioners, significantly contributing to the safe operation of solar power generation systems and the maintenance of power generation capacity. Furthermore, it is an unprecedented remote monitoring device capable of detecting cable theft (disconnection) on the DC side. ◆ Measurement of insulation resistance of solar cell strings (DC ground fault detection and ground fault location identification) ◆ Measurement of bypass routes ◆ Measurement of blocking diodes (reverse current prevention diodes) ◆ Measurement of operating voltage of solar cell strings

I-V curve tracer that measures the generation quadrant and reverse voltage quadrant with electronic load function and reverse voltage application function [Demo unit available for loan◎].

In addition to measuring the power generation quadrant characteristics of solar cells, measuring the reverse voltage quadrant characteristics allows for accurate short-circuit current (Isc) measurements and also enables the measurement of bypass diode characteristics within the solar cells. We will configure a solar cell evaluation system centered around this device to meet customer requirements. We can also propose systems such as measurement systems in an open state and grid-connected measurement systems using power conditioners. ◆ The electronic load and reverse voltage application function allow for I-V curve checks in both the power generation quadrant and the reverse voltage quadrant. ◆ The sweep direction is variable: short-circuit to open-circuit, open-circuit to short-circuit, etc. ◆ The sweep time is variable: 150 [ms] to 1000 [ms]. ◆ I-V curves can be checked on-site using a high-resolution color monitor. ◆ Measurements can be taken from a single special solar cell (CPV). ◆ Clear graph displays are achieved through 1024-point measurements. * For more details, please download the PDF or feel free to contact us. * Demo units are also available for loan, so please get in touch.

The "Mechanical Stitch Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact to the base material. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.
