US scientists have utilized a nanochannels device to cool down the operating temperature of a commercial PV module and have found that the proposed technique is able to improve power yield by up to 32.8%. Spray droplets are dispersed over the nanochannels device in order to eliminate the need for a continuous supply of a coolant.

Developed by Canadian start-up Salient Energy, the zinc-ion battery has a rated capacity of 60 Ah, a nominal voltage of 1.3 V, and a volumetric energy density of 100 Wh/L. The device measures 26cmx24cmx1.2cm and weighs in at 1.3 kg

or some developers of ground-mounted PV, bifacial modules are already the default technology. The slight cost increase is often outweighed by an increase in energy yield. And yet “agreeing” on the right energy yield of a PV plant has always been the most heated debate between developers, investors, lenders, and technical advisers. Everoze partner Christophe Campistron looks at both sides.

Natural hydrogen is piquing interest. Sometimes referred to as “gold” or “white” hydrogen, natural hydrogen plants offer smaller carbon footprints than sprawling green hydrogen projects, with faster development times, according to Avon McIntyre, executive director of HyTerra.

The clean power numbers published annually by the International Renewable Energy Agency provide a snapshot of the global solar market and, this year, a lot of figures were unchanged from the previous dataset, especially in the off-grid segment.

Japan’s Panasonic claims its new pilot solar-plus-hydrogen facility marks the first attempt to create a factory powered by 100% renewables, via the full-scale use of hydrogen.

Developed by an MIT spin-off, the device is based on a standard, two-electrode electrochemical cell containing conductive polymers, a carbon-graphene hybrid, and a non-flammable liquid electrolyte. The battery cells were tested to perform for 12,000 cycles at 100% depth of discharge.

The new product relies on 23.4%-efficient solar cells and features a short-circuit current of 10.8 A. It can be folded into a briefcase and is claimed to be an ideal solution for camping and outdoor activities.

The solar park will sell power to the Bangladesh Power Development Board at a price of $0.1195/kWh under a 20-year power purchase agreement.

New research has categorized all existing fault detection and localization strategies for grid-connected PV inverters. The overview also provides a classification of various component failure modes and their potential causes in a tabular form.
