pv magazine Webinar | UVID: Risks, detection, and Impact on solar projects

Ultraviolet induced degradation (UVID) has emerged as a major reliability concern in the latest high efficiency solar cells and modules. Results from the lab and the field show that if not well managed, vulnerability to UVID can lead to substantial performance loss in the field, enough to threaten the profitability of many projects.

Investors, insurers and other stakeholders now expect UVID testing of modules before deployment, along with specific assurances that this mechanism won’t threaten project performance further down the line.

In this pv magazine Webinar, we examine the emergence of UVID as a concern for the PV industry, which cell types, processes and material choices most greatly influence a module’s susceptibility to UVID, and what manufacturers are already doing to bring the issue under control.

We also take a closer look at the accelerated testing designed to reveal UVID vulnerabilities, and how this compares to what happens to modules in the field, particularly when installed in high-UV environments such as desert regions or at high altitudes.

Tristan Erion-Lorico, vice president of sales and marketing at module testing lab Kiwa PVEL, will join to share insights on how UVID can affect module performance and the tests designed to reveal susceptibility.

We’ll hear from Yong Sheng Khoo, chief operating officer at Quantified Energy and Johnson Wong, its chief scientist, about large scale field distributions of UVID impacted modules from aerial drone EL imaging footage. From these images, the module power loss can be estimated, and on this basis, one can identify clusters in the solar farm with significant early degradation.
