Given the significant wealth of data available from an energy generation asset today, it’s perhaps easy to overlook the availability and value from around the asset as well. Katie Applebaum, business development manager at Clir Renewables, explains why this ‘data disarray’ is preventing solar assets from reaching their full potential.

As solar continues to proliferate and the very first large-scale arrays exceed 10 years of operational life, the value of operations and maintenance services is forecast to skyrocket. But as Edith Hancock writes, industry pressures such as new technologies and consolidation, are reshaping the industry.

Bifaciality and trackers have become almost synonymous with modern plant design, but modelling gains in a real-world environment is notoriously difficult. Liam Stoker reports from a panel at the Solar Finance & Investment Europe conference which explored how new technologies are driving yield upside.

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 renewed importance on product testing and inspection. Here, Enertis explores the role of electroluminescence inspection throughout the lifespan of a PV project.

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.

Many of the bifacial modules now offered by PV manufacturers employ 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 PID-related losses in bifacial PERC+ modules in the field.

Understanding of LeTID remains incomplete, although its effects on PV power plant performance are recognised as being potentially significant. Tabea Luka, 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 in minimising its impact.

The use of unmanned aerial vehicles in solar operations and maintenance can reduce costs and save hours of painstaking labour, but only if applied correctly. Aline Kirsten Vidal de Oliveira, Mohammadreza Aghaei and Ricardo Rüther explore the optimal use of aerial inspections and emerging methods for analysing the data they gather to identify faults.

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.
