Showden Co., Ltd. (4-3-8 Taihei, Sumida-ku, Tokyo, President and CEO Mitsuaki Ota) will launch the lightning protection product for photovoltaic (PV) systems, the PV SPD "ADN Series," starting in April 2013. The ADN Series is an SPD that protects the power conditioning system (PCS), solar panels, junction boxes, and collection boxes from induced lightning and direct strikes that enter the DC system of PV systems. The PV market has rapidly expanded since the introduction of the "Feed-in Tariff System for Solar Power Generation" in July 2012. Additionally, a survey by NEDO (New Energy and Industrial Technology Development Organization) indicates an increasing trend in the number of PV damage incidents caused by lightning. According to the latest data (2008), approximately 28% of all damages are attributed to lightning, which poses risks not only to expensive equipment like PCS but also to power generation interruptions. Showden has developed lightning protection products to safeguard PV systems from lightning damage and enable safer system operation. The PV SPD "ADN Series" features an internal separation mechanism that safely disconnects the SPD elements from the DC system in the event of degradation or failure due to lightning. It is a high-end model equipped with plug-in capability, SPD degradation indicators, and alarm outputs.
