DuPont and Fraunhofer ISE will work together to validate a new set of accelerated testing methods for solar module degradation.
Fraunhofer ISE will run the rule over DuPont Photovoltaic Solutions’ in-house testing practices and then look to refine them. The target is to develop a set of simpler tests to replicate the field degradation of a solar panel, which the pair describe in a statement as “one of the biggest challenges of the PV industry”.
“The aim of this work is to determine whether the proposed accelerated testing protocols can accurately predict service lifetime of solar panels made with different types of materials,” said Dr. Karl-Anders Weiss, project manager, Fraunhofer ISE. “Our intent is to move from the current IEC standards which are limited to predicting early stage failure mechanisms, to a longer-term view of panel ageing in the field.”
The starting point for the new procedures is DuPont’s Module Accelerated Sequential Testing protocol. It subjects modules to repeated phases of damp heat, UV and thermal cycling to replicate the rigours of field operations.
Dr. Kaushik Roy Choudhury, Global Reliability Manager, DuPont Photovoltaic Solutions said: “We are pleased to be working alongside the scientists at Fraunhofer ISE, to help validate our set of accelerated tests. Studying how panels age in the field under multiple environmental stresses is critical for customers and future development of materials.”
Last year DuPont and Envision began a partnership using the latter’s IoT platform to monitor module performance and degradation patterns.

Penang, Malaysia (also available virtually)
Understand fully the technical and logistical supply chains that determine the production and performance of solar modules, including all related factors impacting quality, reliability & bankability. This event will be run as a live event in Penang for delegates able to attend and will also welcome virtual delegates via streamed content and online networking.
Oct 27 - Oct 29, 2020
Going into its fifth year over 200 delegates from 150 companies and 20 countries representing the PV supply chain will gather (virtually, due to COVID-19) for 3 days to discuss the technology roadmaps for PV cell advancement in GW markets. The scope of the event has been expanded this year, to cover developments in wafer supply and thin-film investments and technologies alongside all the regular benefits to all stakeholders tracking PV technology and investment trends for the next 5 years.
