Since the Great East Japan Earthquake in 2011, a shift towards renewable energies and power plant projects has been spreading across the country. Although providing a stable energy supply under natural environmental influences can be challenging, ensuring long-term stable operation is key for a sound business.

Third-party certification can considerably increase reliability and keep investment risks low. TÜV Rheinland Japan supports highly responsible power plant management and provides certification for solar power plants worldwide.

More than 30 years of extensive experience in the technical evaluation of photovoltaics made TÜV Rheinland Japan the best choice for Tess Engineering Co., Ltd. In accordance with the International Standard IEC 62446 and local Japanese standards and regulations (JIS and JEMA), TÜV Rheinland Japan carried out an inspection and comprehensive conformity assessment. Neutral, third-party certification validated power plant reliability in quality, performance and safety.

Conducted by qualified Japanese inspectors, the evaluation and inspection of the plant was broken into three stages. Stage one included the planning and installation of the power plant. Processes from installation to operation underwent technical evaluation in stage two and stage three focused on the overall plant operation. Periodic audits are subsequently conducted to check the plant's safety and quality at three-year intervals.

This comprehensive certification process minimizes safety risks for power plant operators as well as improves bankability and increases return in investment (ROI) for investors.

TÜV Rheinland supported Tess Engineering Co., Ltd. by providing:

• Highly qualified and experienced experts to conduct the required photovoltaic services.
• Holistic, independent assessment and certification supporting the plant as a sound financial investment.
• Quality assurance and expertise to secure the investment.
