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.
Spain’s self-consumption solar boom leaves trail of technical faults in C&I installations
A survey of more than 800 Spanish C&I PV installations following the 2019–2022 self-consumption boom found significant administrative, technical and monitoring deficiencies in all audited systems, with 13.2% of businesses reporting savings far below expectations.
UK solar hits 21.8 GW
State support for solar should result in a record year for PV deployment in the United Kingdom, with strong provisional January data putting market on a good footing. Pipeline of CfD plants due in 2026 plus ramping up of support for rooftop set the stage for accelerated capacity additions.
Chinese PV Industry Brief: Polysilicon prices slide amid low operating rates
The China Nonferrous Metals Industry Association (CNMIA) says polysilicon production has fallen to 32% of capacity, sustaining oversupply, while wafer prices weaken as post–Chinese New Year demand fails to recover.
UK grid software cuts MV solar connection quotes to 15 minutes
A new automated platform allows commercial and industrial rooftop solar developers to receive medium-voltage connection assessments from network operators in 15 minutes.
Malaysia’s TTVision enters India’s solar manufacturing market
TTVision Holdings Berhad plans to commission a joint venture manufacturing facility in India in the second half of 2026 to supply inspection and automation systems for solar production lines.
Vanadium flow and lithium-ion combine in world’s largest grid-forming hybrid storage plant in China
China brings online 300 MW/1,200 MWh grid-forming energy storage facility in Inner Mongolia, integrating lithium-ion and vanadium flow battery technologies.
Chinese Academy of Sciences achieves world record efficiency of 15.45% for kesterite solar cell
The cell was fabricated using a new interfacial phase equilibrium strategy that suppressed uncontrollable metal ion migration. The device achieved an exceptionally high open-circuit voltage of over 600 mV at a bandgap of 1.10 eV.
Batteries replace diesel backup at wastewater plant in New York
Viridi batteries have been deployed in New York to replace diesel generators, accelerating a trend where batteries replace and complement generators of all sizes.
Chinese scientists build ‘ultra-stable’ polymer solar cell with 19.1% efficiency
The polymer solar cell is able to retain 97% of its performance after 2,000 hours in air. By blending small-molecule acceptors into polymeric matrices, the research team improved molecular packing, enhancing both stability and charge transport for “ultra-stable” flexible devices.
