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.
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.
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.
Ideal Heating launches new monobloc propane heat pump for commercial buildings
The UK-based manufacturer has expanded its Ecomod 290HT range with a new 65 kW monobloc air-source heat pump using R290 refrigerant, offering flow temperatures up to 70 C, a COP of 4.6, and cascade capability of up to 7 units.
Australian startup scaling up printed solar technology
Kardinia Energy has secured AUD 2.15 million from the Australian government’s Industry Growth Program to scale up its flexible, low-cost printed solar technology from university proof-of-concept to pilot manufacturing.
The future of solar is unwritten
Whatever decision the U.S. Department of Commerce makes on polysilicon imports, some market segments are in for a bumpy ride in 2026 as the expiration of tax credits and other policy levers change the trading environment faced by residential installers and others. Jesse Pichel and Lev Seleznov of Roth Capital assess what lies ahead for U.S. solar.
