Researchers in California have created a new diagnostic metric that can reportedly predict if a battery can successfully power a specific task. The proposed model could be used in electric vehicles, unmanned aerial systems, and grid storage applications.

Researchers in China have built an off-grid rapid-cycling sorption-based atmospheric water harvesting system. Powered by three PV modules, the system was tested with four condensation methods indoor and outdoor.

Researchers have developed a stagnant water layer cooling concept and tested it using seawater, tap water, and desalinated water. The panel temperature decreased by up to 8.2 °C, while power output increased by approximately 28%.

Researchers have tested a 9 x 11 floating box array for offshore photovoltaics in a large wave flume, under regular and irregular wave sequences. They have placed wireless gyroscopes on three of the boxes, representing the front, middle, and rear positions.

The Chinese storage system manufacturer said its 12.8 V product is designed for RV travelers, off-grid homeowners and marine users. It reportedly provides over 6,000 cycles at 90% depth-of-discharge.

Using Lyon as a case study, an international research team has simulated the effects of rooftop photovoltaic (PV) coverage in an urban area at three levels: 25%, 60%, and 100%. The results have shown that solar panels can raise daytime temperatures by up to 0.72 °C, while cooling nighttime temperatures by up to 0.42 °C. In addition, daytime air conditioning demand has decreased by about 5%.

An Indian-British research team has developed a building-integrated linear concentrating PV facade by sandwiching an asymmetric compound parabolic concentrator, PERC cells, and encapsulation layers between two sheets of glass. The system was tested under both indoor and outdoor conditions and its payback period was found to be of up to 11 years.

Chinese manufacturer Sunwoda Energy introduced a modular all-in-one energy storage system with up to 40 kWh capacity and 30 kW output for residential and small commercial use.

Scientists in Finland have created a special platform to assess the performance of PV modules operating under Arctic conditions. Specifically, it provides data for efficient system design and performance modelling validation, with azimuth and tilt angle being key parameters.

Researchers in Qatar have used an algorithm relying on a variant of the popular logic-based puzzle to determine the optimal way to eliminate cluster shading. They have tested the new approach under fixed and moving shadows.
