The U.S. manufacturer said its new heat pump water heater can provide up to 60% more hot water than standard electric water heaters. The system is available in 240 V and 120 V options and with a capacity ranging from 160 L to 190 L.

The researchers said they optimized the low-bandgap inverted perovskite cells through a passivating aluminum oxide (Al2O3) interlayer deposited via atomic layer deposition (ALD), which significantly helped improve device efficiency.

pv magazine is compiling a guide to home solar installations, aimed at those who are interested in installing but are new to the market and want to make an informed decision. We have spoken to associations, installers and industry specialists in major solar markets across the globe to compile best practice guidance and advice that aims to be applicable to home solar installations anywhere in the world. 

Australian battery solutions provider RedEarth Energy Storage has announced an international partnership that will see it jointly develop an integrated hardware and energy management system combining solar, storage, and bidirectional electric vehicle charging capabilities in a single unit.

A digital product passport could support circular practices in the European PV industry by better tracking material composition, recyclability, and supplier information, crucial for material recovery.

The King Abdullah University of Science and Technology and the Fraunhofer Institute for Solar Energy Systems report producing perovskite-silicon tandem solar cells with open-circuit voltages exceeding 1.9 V as the result of a two-step hybrid evaporated/blade-coated process for perovskite films.

Researchers in South Korea have conducted a literature review on recorded cases of floating PV plants placed on mine pit lakes and tailings ponds, both of which are byproducts of the mining industry. Looking at more than dozens of cases, they have concluded that mine pit lakes generally provide more stable environments for deployment.

GCL Optoelectronics has achieved 29.51% efficiency for its perovskite-silicon tandem solar module, with the result certified by China’s National Institute of Metrology.

The European Commission says it will introduce an energy storage package in 2025, as outlined in a new report on progress by member states toward 2030 clean energy targets.

Researchers in China conceived a new PV forecasting approach that integrates causal convolution, recurrent structures, attention mechanisms, and the Kolmogorov–Arnold Network (KAN). Experimental results demonstrate that the proposed model outperforms 10 existing forecasting models.
