New process to recycle silicon, silver and glass from end-of-life PV panels
A €4.8 million EU-funded research project is aiming to develop a process that allows recovering all components of a photovoltaic module.
Building renovations crucial for heat pump deployment
Building renovations may result in up to 51% space heating demand savings, according to recent research from Germany. Its authors claim that, if buildings are retrofitted and thermal energy storage and individual hybrid heat pumps with back-up gas boilers are applied on a large scale, significant heat cost reduction may be achieved across the whole of Europe.
Green Cell unveils off-grid inverters for small residential buildings
Poland-based Green Cell is offering two versions of its new inverter, with power outputs of 1 kW and 3 kW. The inverters feature an efficiency of 90% and are recommended for small buildings such as cottages or year-round homes.
Cathode discovery ‘opens up new pathways’ for calcium-ion storage
Scientists in South Korea tested a new cathode material as part of a calcium-ion battery (CIB), achieving some impressive results. The material retained more than 90% of it initial capacity after 500 cycles, alongside some of the best performance results seen so far for this technology. The scientists say that this discovery opens up “an unexplored pathway toward the realization of stable and high-power cathodes in CIBs.”
Perovskite solar panel with 16.1% efficiency via ambient air blade-coating
The panel, fabricated by scientists in Italy, is composed of five series-connected cells, each with an area of 2.01 cm² and has an aperture area of 11 cm². It showed a power conversion efficiency of 16.1%, an open-circuit voltage of 5.59 V, a short-circuit current of 37 mA, and a fill factor of 72.5%.
Solarwatt, BMW launch new storage system for residential PV
The smallest of the storage units has a capacity of 4.8 kWh and an output of 1.5 kW. It can be expanded to eight battery modules in steps of 2.4 kWh and has a maximum of 57.6 kWh, and 6 kW, of power.
New walkways for the installation of rooftop PV systems
Spanish mounting system provider Alusín Solar has developed a solution to enable the transit of installers on roofs. It has recently commissioned a production line for this product, which it dubbed Carex.
Solar module cooling technique based on multiple phase-change materials
Academics have utilized three PCMs, known as RT26, RT35, and RT42, and decided to pack them ascendingly depending on their melting points and heat-flow direction. The system is claimed to allow lower melting rates and longer thermal management of the modules.
Northvolt gets cash boost to expand capacity of Swedish gigafactory to 60 GWh
The battery manufacturer is planning to raise $2.75 billion through a private placement and to use the funds to expand the capacity of its lithium-ion battery manufacturing site which is currently under construction in Sweden, from 40 GWh to 60 GWh.
Solar microgrid to offer protection from fire threats
Remote grids provide enhanced reliability, lower risk profiles, and lower total costs than existing distribution lines.
