China’s SPIC offering copper-based heterojunction solar modules
The Chinese module maker is preparing to bring to the market 25.97%-efficient heterojunction solar cells based on copper metallization. The new products are based on ultra-narrow 9-micron busbars, vacuum-deposited copper interconnects and proprietary interface engineering.
Airport-based green hydrogen test plant paves way for zero emissions aviation
Aotearoa-based green hydrogen solutions company Fabrum has opened an advanced liquid hydrogen test facility in partnership with Christchurch International Airport, believed to be the first at an airport that can provide hydrogen on demand.
GivEnergy launches Gen 3 hybrid inverters for pairing with stackable storage
The new single phase hybrid range includes 8 kW and 10 kW models.
Midea Hiconics releases 30.6 kWh storage system for residential PV
The all-in-one single-phase system can take up to 3,750 W of PV input. It can be stacked with two to six batteries.
Brazilian plastics manufacturer offers reflective membrane for bifacial PV plants
Azul Pack has developed a new reflective membrane to increase albedo and energy yield in photovoltaic plants with bifacial modules. In a fixed structure plant located in Minas Gerais, the technology reportedly resulted in a 7% increase in energy at the inverter output.
New study shows reducing number of solar modules per string reduces risk of hotspots
Scientists in Indonesia have investigated early operational defects in a 24.9 MW solar PV system in Sumatra and have identified hotspot formation as the dominant defect. They also detected 282 cases of glass cracking, 350 cases of junction box failures and shading effects linked to module defects.
Swiss consortium switches on vertical solar-plus-storage project
The Baumgarten solar project consists of a 366 kW ground-mounted vertical PV array and a 2.5 MW/3 MWh storage facility.
PVT-assisted air-source heat pump based on phase-change tank
Scientists in China have designed a photovoltaic-thermal integrated air-source heat pump hot water system that uses a phase change tank to lower energy consumption and achieve higher power generation performance than conventional heat pumps. The system is designed to use water as a working medium and to provide circulation power for forced circulation.
Water-based recycling of perovskite solar cells
An international team has developed a new technique to recycle perovskite solar cells (PSC) made on glass substrates using a water-based solution. Tests showed that the recycled cells were as efficient and stable as the original devices.
Hybrid solar vanadium battery system withstands Australia’s harsh weather
Energy solutions company Australian Flow Batteries has rolled out its containerised solar vanadium battery system in Western Australia, which can be stowed in less than an hour to protect modules during the region’s annual cyclone season.
