Welcome to volume 23 of PV Tech Power. The continuing COVID-19 pandemic has, in just a few short months, changed global economies beyond recognition and as countless analyses have stressed of late, the energy sector is no different.

Pages 12 through 21 document not just the pandemic’s impact, but how the industry has reacted. You won’t be surprised to read just how quickly the sector has responded to the crisis. Furthermore, we take a glance forward at what the emergent global economy will look like once the crisis subsides and, crucially, the role solar may play.

PVTP Paper
PV Tech Power Papers, Storage & Smart Power
Our ability to generate renewable energy is scaling up fast, and solutions to integrate that energy will rely on technologies like blockchain to help keep new solutions on track. Power Ledger’s executive chairman and co-founder, Dr Jemma Green, looks at the role blockchain plays within her company’s platform to integrate and automate solar energy trading and balancing.

PV Tech Power Papers, Storage & Smart Power
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.

PV Tech Power Papers, Storage & Smart Power
Battery system integrators must navigate a broad array of technologies and varying market drivers when putting systems together. Andy Colthorpe speaks to Powin Energy and Sungrow about the engineering challenges involved in building lithium-ion battery storage systems at scale.
PVTP Paper
PV Tech Power Papers, Storage & Smart Power
In the second of a two-part series for this journal, Jens Noack, Nataliya Roznyatovskaya, Chris Menictas and Maria Skyllas-Kazacos from CENELEST, a joint research venture between the Fraunhofer Institute for Chemical Technology and the University of New South Wales, examine the potential of vanadium redox flow batteries in the future energy system.
PVTP Paper
Financial, Legal, Professional, PV Tech Power Papers
José Rojo speaks to Roger Font of Banco Sabadell for his take on the financing landscape for unsubsidised PV projects following the COVID-19 outbreak.
PVTP Paper
Financial, Legal, Professional, PV Tech Power Papers
The growing volumes of variable solar and wind generation on the grid raise the risk of depressed wholesale prices, particularly at times of high generation and low demand. James Brabben of Cornwall Insight explores the phenomenon of so-called price cannibalisation and how its most serious potential impacts on the renewables industry can be avoided.
PVTP Paper
Design & Build, PV Tech Power Papers
The era of subsidy-free solar is well underway in a growing number of markets, with Europe leading the way. As  Solarcentury’s Peer Piske explains, the greater sensitivities around modelling zero-subsidy projects mean new approaches to design and planning are required by developers.
PVTP Paper
Plant Performance, PV Tech Power Papers
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.
PVTP Paper
Plant Performance, PV Tech Power Papers
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.
PVTP Paper
Plant Performance, PV Tech Power Papers
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.
PVTP Paper
Project Briefing, PV Tech Power Papers, System Integration
On 10 April 2020, South Africa’s biggest solar PV complex to date sprang into operation as the final phase was completed. The timing was extremely fortunate, just a day ahead of the country’s government announcing a nationwide lockdown as the COVID-19 pandemic continued to spread worldwide.
PVTP Paper
PV Tech Power Papers, System Integration
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.
PVTP Paper
Market Watch, PV Tech Power Papers
Recently name checked as among the cheapest places in the world to develop solar, Chile has emerged as a particularly popular destination for solar finance. But as the country proceeds towards a 100% renewables target, political instability and legacy network issues stand in its way. Molly Lempriere explores how Chile can leap those hurdles on its way to a green grid.
