Long-term quality assurance testing at Sharp Corporation on DuPont Photovoltaic Solutions backsheet and metallisation pastes have been concluded with the materials passing stringent tests.
The company said that Sharp’s in-house testing regime went passed current International Electrotechnical Commission (IEC) standards, and required PV module, component and material testing that also included data analysis from a 30-year operation history of a solar module, made with DuPont’s ‘Tedlar’ polyvinyl fluoride backsheet film that was installed at the Tsubosaka Temple in Nara, Japan.
“Sharp has imposed a quality assessment standard that exceeds the current industry standards institutionalised by the IEC,” said Hideki Yoshioka, general manager, quality and environment, solar system group, Sharp. “Sharp’s standard consists of panel-based testing as well as testing of materials and components. Materials are critical in determining how well and how long panels perform, and we are pleased to collaborate with material manufacturers such as DuPont to gain insights on materials and ensure we exceed the expectations of our valued customers.”
Conrad Burke, global marketing director, DuPont Photovoltaic Solutions said: “In an environment where some manufacturers are cutting costs by cutting corners on quality, higher standards are essential to ensure the continued growth and success of solar.”
