• Lightning protection

The active installation and introduction of "new energy" sources such as solar power and wind power are progressing. However, these new energy facilities are exposed to various risks, including troubles caused by lightning strikes. In particular, solar power systems have many cables, wiring points, and control devices that connect solar modules and power systems, all of which are threatened by lightning. At Showden, we can provide appropriate lightning protection measures for solar power systems of all configurations, tailored to various purposes such as mega-solar projects, offices, and factories. [We are currently offering a free collection of lightning protection case studies by power generation system] [For more details, please download the catalog or feel free to contact us]

The lightning protection product for solar power generation, the PV SPD "ADN Series," is designed to protect components such as the PCS (Power Conditioner), solar panels, junction boxes, and collection boxes from induced lightning and direct strikes that invade the DC system of PV systems. According to a survey by NEDO (New Energy and Industrial Technology Development Organization), the number of PV damage incidents due to lightning is on the rise. The latest data from 2008 indicates that approximately 28% of all damages are attributed to lightning, posing risks not only to expensive equipment like PCS but also to power generation interruptions. The PV SPD "ADN Series" features an internal separation mechanism that allows for the safe disconnection of the SPD element from the DC system in the event of degradation or failure due to lightning. It is a high-end model equipped with plug-in capabilities, SPD degradation indicators, and alarm outputs. For more details, please contact us or download the catalog.
