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
The European Union has pinned its hopes for an economic recovery in the wake of the COVID-19 pandemic on green and digital technologies. Molly Lempriere looks at the part solar could play as details are fleshed out
The rapid evolution of photovoltaic technology has continued, as modules with peak power outputs in excess of 550W are emerging fast. Driven by a thirst for more power and increasingly larger cells, developers and EPC now face tougher procurement decisions than ever before. But is the industry ready for such a jump? Liam Stoker investigates
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
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
