The proliferation of renewables and other distributed energy resources is pushing existing grid infrastructure to the limit, prompting renewed efforts to modernise. But with new hardware coming at such a high price, it’s imperative these investments get the biggest bang for their buck. Here, the US Interstate Renewable Energy Council establishes its five key principles for grid modernisation.
Energy storage systems were historically used for grid balancing purposes within Europe, limiting their use to such applications or to be considered as “auxiliaries” to renewable generation assets. However, as market prices evolve and new revenue streams emerge, stakeholders must discover the diverse applications that such systems can tap into, writes Naim El Chami
Alongside the recent rapid boom in bifacial solar deployment, extensive work has been underway to fine-tune the yield modelling of bifacial systems. Drawing on case studies from the ATAMOSTEC test site in Chile, researchers involved in the collaborative venture describe how it is helping improve understanding of bifacial yield and the lay the foundations for a set of new rules to inform system design and installation
As larger floating solar projects become a more common sight around the world, bankability is increasingly coming to the fore to satisfy the demands of financiers. Jeremy Ong, Ken Tay and Harald Hammer look at some of the areas where careful due diligence is vital to managing and mitigating technical risks for lenders
Later this year, a new set of industry guidelines will for the first time codify a set of best practices for EPC contractors. Ahead of publication, members of Solar Power Europe’s O&M task force look at some of the critical areas of PV system integration where high-quality EPC work can most effectively influence a project’s lifetime performance
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.
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
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
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
