Comprehensive certification of photovoltaic plants is already widespread in Europe, and this type of inspection by a third-party agency is expected to grow in number and enhance the credibility of solar plants in Japan in the coming years. Ichigo ECO’s Kiryu plant is the second in Japan to have obtained a comprehensive certification.
In the evaluation of
power plants, TÜV Rheinland has many years of experience dealing with international solar plant systems standards IEC 62446 as well as domestic JIS and JEMA standards. By allowing inspections on-site and from the stage of plant construction until the pre-operational period by a neutral third-party inspection agency, Ichigo ECO can increase the reliability, performance quality, and safety of its solar plants. Japanese inspectors with experience in solar power run the inspections and evaluations to quickly respond to domestic certification services.
1. Technical evaluation from a neutral and independent position is performed at every stage:
2. A highly accurate energy yield prediction is conducted, including an on-site shadowing analysis*. Further the project specification is investigated towards completeness and correctness.
3. Before the
photovoltaic modules - PV
are installed on-site, output measurement is performed at TÜV Rheinland Japan's photovoltaic laboratory to ensure the performance.
4. After mechanical completion, a comprehensive on-site inspection with full testing ensures the quality and safety of the plant construction.
TÜV Rheinland’s comprehensive certification for photovoltaic power plants offers the following benefits to plant operators, financial institutions, insurance companies, and investors:
