A comprehensive understanding of the performance gain offered by a bifacial module remains an elusive goal for PV owners and EPCs due to variations arising from different design, manufacturing and testing methods. Vicente Parra, Ruperto J. Gómez, José C. Vázquez and Francisco Álvarez of Enertis review the main sources of variability and outstanding uncertainties that must be addressed as the industry seeks to define standard rules for reliably selecting, purchasing and deploying bifacial PV modules

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

Many of the bifacial modules now offered by PV manufacturers employing bifacial passivated emitter and rear cell (PERC+) technology, making them vulnerable to rear-side potential-induced degradation, in addition to the conventional front-side shunting type (PID-s). Kai Sporleder, Volker Naumann, Stephan Großer, Marko Turek and Christian Hagendorf of the Fraunhofer Centre for Silicon Photovoltaics report on new testing methods designed to quantify the expected power losses of bifacial PERC+ modules in the field
Commissioning should be as integral to the installation of a PV plant as a pre-flight checklist is to an aeroplane journey. Sara Verbruggen reports on the latest tools and technologies being deployed to ensure a smooth commissioning process and a project that operates safely and optimally
By ahul Kar, general manager and VP for New Energy, AutoGrid Systems
The optimal integration of distributed energy resources such as solar, battery storage and smart thermostats becomes an ever-more complex and pressing question. Rahul Kar, general manager and VP for New Energy at AutoGrid Systems looks at the role artificial intelligence can play in smarter energy networks
An increasing number of banks are turning away from fossil fuels and towards renewable energy financing. As Catherine Early reports, despite the chilling effect of the coronavirus pandemic on the industry, hopes are high that a tipping point is nearing.
