Sunday read: A PV band-aid DuPont has developed a repair kit for PV modules with backsheet failures. Cracked and chalking backsheets can cause problems for solar project owners, but this could easily be addressed in the field without swapping out the PV modules. Stéphan Padlewski, regional marketing leader EMEA at DuPont Photovoltaic Solutions, spoke to pv magazine about how the solution works.

From toothbrushes to saving the planet: How ultrasonic delamination could hold the key to battery recycling The use of ultrasonic sound waves has been applied to battery recovery. Researchers from the ReLiB project at the U.K.’s Faraday Institution say the process has already proven to be 100 times faster than conventional approaches. It is also much more sustainable and less energy intensive.

Saturday read: the more you know Module-level power electronics, most often in the form of power optimisers and microinverters, offer a range of value propositions, including advanced monitoring capabilities. But how much can the little box behind the module really see, and how much do operators actually need to know to keep a power plant running optimally?

Battery costs have fallen 97% since 1991, claim MIT researchers Academics reviewed the historic price development of lithium-ion batteries and found the accepted model does not accurately reflect the full cost decline and technological improvement which has taken place. With more data points to compare, the team found batteries had improved even more than previously assumed.

Location-dependent performance model for bifacial installations Bifacial PV modules and single-axis trackers go well together, but a global research team has now noted that a comprehensive location-dependent performance analysis still has yet to be done. Their findings could help to determine the right plant setups in different locations throughout the world.
