Technology and R&D

Spanish building integrated PV manufacturer Onyx Solar is delivering a custom building integrated PV system featuring almost 1,800 solar glass ‘louvres’ designed to help power Australian tech giant Atlassian’s new 39-storey headquarters in downtown Sydney with 100% renewable energy.

Cubenergy has launched FlexCombo 2.0, a scalable battery energy storage system for utility, commercial, and industrial applications, offering up to 16 MWh capacity with LFP batteries. Its modular design, advanced BMS, and cloud-based operations enable easy installation, seamless expansion, and efficient grid integration, according to the manufacturer.

The new Tesla Solar Panel and mounting system pairs with the company’s inverter, Powerwall battery, EV charging and vehicles, creating an all-Tesla residential solar offering for the first time.

Conceived for stationary energy storage, the proposed sodium-ion battery configuration relies on an P2-type cathode material and an hard carbon anode material that reportedly ensure full-cell performance. Electrochemical testing revealed initial capacities of 200 mAh/g for the cathode and 360 mAh/g for the anode with capacity retentions of 42% and 67.4% after 100 cycles.

The Ariya demonstration vehicle features 3.8 m² of Lightyear’s custom solar panels integrated across the hood, roof, and tailgate. Testing showed that the car could generate 0.5 kWh of solar energy during a 2‑hour, 80 kilometer trip, delivering up to 3 kilometres of range at no extra cost or charging time.

South Korean researchers from Chungnam National University have developed a one-step, photoresist-free graphene patterning technique that results in very low electrical resistance and avoids damage, showing scalability in the fabrication of transparent, flexible electronics like solar cells.

Engineers at the University of New South Wales have developed a real-time monitoring technique that reveals how silicon solar cells can self-repair following ultraviolet-induced damage, offering new insights into solar panel degradation and lifetime performance.

Australian manufacturer Siltrax will push forward with the commercialisation of its silicon-based hydrogen fuel cell technology after securing the tick of approval from international testing, inspection, and certification body TÜV Rheinland.

With silver prices rising, more large solar manufacturers are expected to switch to copper for cell metallization. Radovan Kopecek of ISC Konstanz tells pv magazine that he expects the entire industry to follow. Ning Song of the University of New South Wales says a small efficiency tradeoff may be acceptable if the cost savings are significant and do not introduce new reliability risks.

Chinese manufacturer Sungrow has introduced a new utility string inverter, a three-phase hybrid inverter for commercial and industrial applications, and a liquid-cooled energy storage system.
