Welcome to the latest edition of PV Tech Power. This is a special issue for a number of reasons. The journal has now been running for five years with a growing roster of industry experts sharing in-depth knowhow on everything from contract law to the pitfalls of east-west module layout. It’s also a special issue for us as it is the tightest marriage yet of PV Tech’s decade-plus of solar industry coverage and the expert analysis and reporting of our sister site Energy-Storage.News. Our 19-page special report in this issue explores both the accomplishments of the energy storage sector and the ongoing challenges. Fittingly, Andy Colthorpe, editor of Energy-Storage.News, sets the scene (p.20). Looking ahead we investigate the growing trend for DC-coupled storage systems in the US in particular and at all scales (p.29). VDE’s Jan Geder meanwhile, looks at the very necessary technical work going on to ensure that the energy storage boom is both bankable and insurable (p.40). Recycling is another area where the storage sector has more to do. The consultancy firm Li-Cycle explains why a battery powered future means creating recyclable products now, or risk jeopardising the tech’s positive legacy (p.45). Our regular Storage & Smart Power section also includes a feature from UK editor Liam Stoker taking a deep dive into the role of storage and other technologies limiting the damage done by a major blackout in the UK this summer (p.114). This edition is not universally focussed on storage however. PV Evolution Labs’ Michael Mills-Price and Jenya Meydbray discuss their inverter scorecard report. As the main driver of corrective maintenance they argue the case for comprehensive quality benchmarks in inverters (p.94). José Rojo looks at two of Latin America’s most vibrant markets, Mexico and Brazil. We also have an update on Taiwan’s solar market as the focus shifts from pure manufacturing to deployment as well (p.59), a closer look at the impact of the bifacial trade tariff exemption in the States (p.48) and much more.
