‘Cool roofs’ increase power yield in bifacial rooftop PV systems
A Spanish-Algerian research group has tested how “cool roofs” could help increase power yield in rooftop bifacial PV systems. Cool roofs are based on coating materials with high reflectance properties.
New MPPT approach for multi-string PV systems under partial shading
Egyptian researchers has developed a multi-string PV system with a converter control strategy, achieving 99.81% efficiency with a direct duty cycle for maximum power point tracking (MPPT).
Residential photovoltaic panels with high partial shading tolerance, high voltage
Scientists from South Korea have designed new photovoltaic modules with both rectangular and triangular shapes and solar cells connected in parallel, which they said have higher partial-shading tolerance compared with cells connected in strings. The panels are reportedly less sensitive to partial-shading geometries than shingled modules.
UNSW researchers claim to have developed method for viable, decentralised green ammonia production
Researchers from UNSW say they have found a commercially viable pathway to the decentralised production of green, renewable ammonia. An alternative to the traditional Haber-Bosch method, the researchers used nanosecond pulsed plasma bubbles coupled with electrocatalysis.
Researchers shed light on mysterious, higher energy yields in vertical PV systems
Scientists in the Netherlands have sought to understand the reason for unexpected gains in vertical PV systems and found that these installations have a much higher heat transfer coefficient than their horizontally deployed counterparts.
Green Gravity signs deal to roll out energy storage tech in Romania
Australian energy storage startup Green Gravity will explore opportunities to deploy its gravitational energy storage technology in Europe after inking an agreement with the Romanian state-owned energy company Complexul Energetic Valea Jiului SA.
Solar-plus-storage outperforms diesel in US military survival analysis
The US Department of Energy’s National Renewable Energy Laboratory (NREL) has determined that Antora Energy’s solar-plus-storage system meets the US military’s stringent standards, as it significantly outperforms emergency diesel generators in survivability probabilities.
Queensland commits to critical minerals processing plant
With the clean energy transition driving a global increase in demand for critical minerals, the Queensland government has declared Townsville will be home to Australia’s first state-owned processing facility for critical minerals like vanadium.
New grid-scale battery design stacks up for Altech
Western Australian battery technology company Altech Batteries has updated the design of its 1 MWh sodium chloride battery energy storage system, paving the way for the modular units to be stacked three high, allowing for smaller project footprints that conserves valuable land area.
Novel algorithm estimates global maximum power point in partially shaded PV systems
Developed by scientists in India, the global maximum power point (GMPP) technique is based on the voltage and current of strings in a PV array. The research group tested it in computer simulation, as well as through an experimental setup.
