The cost of insuring operational solar farms has skyrocketed over the course of the year, triggered by carriers rethinking their approaches to natural catastrophes and other extreme weather events. This has placed additional importance on mitigation strategies. Kevin Christy, COO for North America at Lightsource bp, details how the solar developer has adapted its strategy in the field.

Utility-scale solar is evolving beyond traditional measurements, and performance ratio are one such metric that is likely to become obsolete, replaced by more modern criteria such as availability metrics. Carsten Steenberg, VP of product management and business development at Rainwise, explores the new metrics coming to the fore and discusses the importance of weather monitoring.

The advancement of solar cell and module technology has meant ever larger, higher power modules are being manufactured, shipped and installed at increasing speeds, placing new importance on product testing and inspection. Here, Enertis explores the role of electroluminescence inspection throughout the supply phase.

Despite the importance of reliability to the cost competitiveness of PV, large data sets enabling high-level investigation of the technology’s performance in the field are relatively scarce. Dirk C. Jordan, Chris Deline, Bill Marion and Teresa Barnes of the National Renewable Energy Laboratory, and Mark Bolinger of the Lawrence Berkeley National Laboratory study a unique data set of 100,000 PV systems in the US, drawing out tips for better reliability that have relevance to other parts of the world.

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

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.

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
