Growatt debuts high-voltage battery for residential, small C&I solar
The APX HV Battery 2.0 supports 5–30 kWh capacities and up to 15 kW of output. The IP66-rated system features a stacked, cable-free design.
Scientists build near-white HJT solar cell for BIPV applications
The lab-scale, near-white heterojunction solar cell uses nanoclay-based scattering layers combined with dielectric multilayer films to preserve power conversion efficiency while enhancing visual appeal. The researchers report optical losses of less than 1% at a 50% clay volume fraction, which are significantly lower than those observed with textured glass.
Printed solar manufacturer lands $2.15 million grant
Kardinia Energy has received a federal grant worth $2.15 million to help scale production of its Newcastle-based printed solar technology.
Fox ESS releases hybrid inverters for commercial PV
The inverters offer up to 99.2% efficiency, 200% PV oversizing, dual battery inputs, IP65 protection, and support for installations up to 144 kWh of storage capacity.
New single-diode model tackles recombination losses in solar cells
UNSW researchers have developed an intrinsic-adjusted single-diode model that explicitly accounts for radiative and Auger recombination, improving I–V curve accuracy and reducing root mean square error by up to a factor of three. The model is claimed to better predict performance near open-circuit voltage and maximum power point.
New method offers low-cost solution for improving PV system performance
An Australian research team has developed a five-step, rule-based method that detects and classifies underperformance in PV systems using only AC-side inverter data. Validated across more than 1,000 systems, the approach offers a low-cost, low-intervention solution for improving reliability, fault response, and PV system performance.
The effects of solar module elevation on ground-mounted solar
Scientists in Hungary found that ground-mounted solar modules at an intermediate elevation of 1.1 metres achieve the highest efficiency and power output due to improved airflow and reduced cell temperature.
Australian battery manufacturer lands funds for expansion plans
Perth-headquartered energy storage and battery-based power systems specialist Magellan Power has teamed with specialist investment manager Viburnum Funds to boost its manufacturing capabilities and fund expansion in Australia and internationally.
Enphase releases new control software for its IQ8, IQ9 microinverters
The United States company said its Power Control software is designed to help installers reduce costs and streamline interconnection. Among its features is the ability to control aggregate system exports through software-based limits.
Hinen launches 15 kW three-phase hybrid inverter
The Chinese manufacturer said its 15 kW three-phase low-voltage hybrid inverter is paired with the stackable BP5000 5 kWh battery supporting up to 120 kWh. It features three MPPTs, 150% oversized PV input, and smart load management for optimised self-consumption.
