[Taiwanese Research Institute Visits Japan] EneTech and J-PITA Hold Practical Training and Information Exchange on Latest Solar O&M Technology and Theft Prevention

EneTech Inc.'s Matsuo lectures on trends in Japan's solar power generation systems and the latest O&M challenges.

EneTech Inc. (Headquarters: Aichi Prefecture, President and CEO: Yusuke Yoshida, hereinafter referred to as EneTech), which operates an O&M business for renewable energy facilities, hosted a delegation from a Taiwanese research institute in Kyoto from June 1 to 4, 2026, with the cooperation of the Japan Photovoltaic Inspection Technology Association (J-PITA). The event included practical training and an information exchange session on the latest solar power maintenance technologies and security measures.

On the day, Matsuo, Group Director, CTO, and Standing Director of J-PITA, served as the instructor. He shared Japan's know-how for long-term stable operation with the Taiwanese research institute delegation, for whom stable energy supply and decarbonization are important issues. This included demonstrations of defect detection using actual equipment and countermeasures against cable theft, which has become a social problem in Japan. This exchange aims to share Japanese technology and knowledge, deepen international cooperation, and contribute to energy stabilization and the realization of a global decarbonized society.

Background and Objectives of the Information Exchange with the Taiwanese Research Institute

While Taiwan is accelerating the introduction of renewable energy, the importance of O&M (Operation & Maintenance) for the long-term stable operation of facilities is increasing. In this training session, Matsuo introduced trends in Japan's solar power generation systems, which are transitioning from the FIT system to a self-consumption model utilizing PPA, as well as real-world challenges and solutions, such as the increasing failure rate of PCS (Power Conditioners) after more than 10 years of operation.

Details of the Training Session and Site Visit on the Day

On the day, in addition to sharing the latest trends through lectures, explanations were provided with practical examples of O&M practices adapted to Japan's natural environment and social conditions.

Practical training using the latest measurement equipment (Location in Kyoto)

At a solar power plant in Kyoto, practical maintenance training was conducted using specialized equipment such as thermal cameras, drones, and Solarmente Z. Practical know-how for early detection of defects that are difficult to identify visually was provided, including explanations of cluster disconnection in half-cut modules and EL testers for visualizing PID and microcracks.

Physical and psychological measures against increasingly severe theft damage (Introduction of latest cases)

Based on the reality of copper cable theft damage at solar power plants, which has been rapidly increasing in Japan, Matsuo lectured on the latest security measures. To address issues such as theft from handholes and measures for buried piping, a multi-faceted security approach was explained, including the installation of security steel plates, root binding (mortar hardening) of collection boxes, switching to aluminum cables with low resale value, and psychological deterrence through warning signs.

Diversification of energy utilization (Site visits to residential equipment and solar sharing facilities)

In addition to case studies of battery introduction as BCP measures, site visits were conducted to residential solar power facilities and solar sharing facilities in Kyoto, allowing participants to observe diverse models of renewable energy utilization in Japan.

[Comments from the Taiwanese Research Institute]

We sincerely thank J-PITA for meticulously planning and executing this training. The training covered a wide range of topics, including explanations of power sales systems, policies, and current situations, as well as power plant operation management, operation and maintenance of solar power generation systems, and the use of inspection equipment. The content was highly comprehensive and extremely beneficial for practical work.

Furthermore, this provided our participants with an opportunity to gain valuable experience and insights in areas related to policy promotion, inspection-related work for solar power generation, and the promotion of solar power generation and storage systems. This has deepened our understanding of related systems, technological development trends, and practical operations in Japan.

Moreover, through exchanges with companies and site visits, we were able to deepen our knowledge of case studies involving various products and technologies, as well as interactions with local businesses, making it a very fruitful training. We hope to have more opportunities to participate in such exchange activities in the future to continuously enhance our expertise and practical skills in the renewable energy field.
