Towards a test standard of light and elevated temperature-induced degradation

Understanding of LeTID remains incomplete, although its effects on PV power plant performance are recognised as being potentially significant. Friederike Kersten, Matthias Pander, Max Koentopp, Marko Turek, Werner Bergholz and Thomas Pernau of the LeTID Norm consortium outline progress towards developing a standardised test for the defect, a key step inw minimising its impact

Getting the most from bifacial

With the number of bifacial solar projects now rapidly growing, more is being understood about how to design and build systems that play to the technology’s main strengths. Drawing on recent experiences in the field, Beth Copanas and James Willett from RES outline some of the technical lessons learned on realising bifacial’s full potential.

Increase of PID susceptibility of PV modules under enhanced environmental stress

Potential-induced degradation (PID) is still one of the main reasons for unpredictable power losses in PV power plants. Volker Naumann, Otwin Breitenstein, Klemens Ilse, Matthias Pander, Kai Sporleder and Christian Hagendorf of Fraunhofer CSP examine how the PID susceptibility of PV modules is influenced by environmental stress. It is found that PID may develop in originally PID-resistant modules after a period of one to three years of unsuspicious operation, depending on climatic conditions

Kipp & Zonen sold to the Hach Company
