Energielenker releases ‘self-learning’ energy management system
Germany-based Energielenker has developed a “self-learning” energy management system that controls energy flows in buildings with PV systems, using AI algorithms to analyze data from all relevant components.
Organic solar cell gains counterintuitive efficiency boost from entropy
A research team at the University of Kansas have found that organic semiconductors known as non-fullerene acceptors demonstrate a high solar cell efficiency due to a reversed heat flow.
IEA-PVPS identifies 456 patents in PV module recycling
The IEA Photovoltaic Power Systems Programme’s (IEA-PVPS) latest report on solar panel recycling offers a comprehensive review of all existing technologies in this market segment, from pure mechanical recycling to innovative techniques such as as light pulse treatment, water-jet cleaning, pyrolysis, and chemical treatments.
AEG unveils 5 KWh stackable high-voltage battery
Germany’s AEG is selling new stackable, high-voltage batteries with usable capacity of 5 kWh. They come with a 10-year warranty and reportedly have a lifecycle of more than 4,500 cycles.
The Hydrogen Stream: Poland unveils hydrogen strategy
The Polish government has outlined its main objectives for the development of hydrogen, while Tyczka Hydrogen says a damaged compressor from Maximator Hydrogen caused a recent incident at one of its filling stations in Germany.
Energy-storing carbon fibre composites pave the way to weightless batteries
Building on research work at Sweden’s Chalmers University of Technology, Sinonus has developed carbon fiber-based structural batteries that not only store energy but also become an integral part of a product’s structure. Their possible span of energy density is said to be around 25-50% of a conventional lithium-ion battery at current technology level.
Microclimates could bolster case for agrivoltaics
A new paper finds that combining photovoltaics with crop farming can result in revenue gains over the life of a PV system at a diverse range of locations in the United Kingdom. Researcher Aritra Ghosh tells pv magazine that the benefits of agrivoltaics are “multifaceted.”
Solar panel cleaning with electromagnetic waves
Three companies, including US-based startup Sol Clarity, are experimenting with electrodynamic screen systems to clean solar panels using minimal electricity and no water.
Bifacial PV, single-axis tracking produces cheapest electricity, says IEA-PVPS
The IEA Photovoltaic Power Systems Programme’s (IEA-PVPS) latest factsheet covers bifacial PV modules and advanced tracking systems. It says a combination of bifacial modules with single-axis tracking could increase energy output by up to 35%.
Deye releases residential hybrid inverter
Chinese manufacturer Deye says its new three-phase residential hybrid inverter system has a rated output power ranging from 14 kW to 20 kW.
