Researchers have analyzed how wind speed and direction affect the cooling of a rooftop PV plant with 10,806 panels. They say that winds from behind were less effective due to the roof slope and the minimal gap between the panels and the roof, but wind from other directions could contribute to a cooling effect of up to 7 C.

Solinteg has developed the IntegOne HSH, a residential solar storage system that combines a single-phase hybrid inverter with one or two batteries. Up to 10 systems can connect in parallel, offering a maximum efficiency of 97.6%.

Researchers have developed a novel deep-learning method to predict ultra-short-term PV power, using an optimization method that is based on the behavior of dung beetles. The proposed approach reportedly performed better than seven other conventional prediction methods over a 1-year period.

US-based Bluetti has developed a new energy storage system (ESS) that offers up to 154.8 kWh of storage and 60 kW of output by connecting up to three systems in parallel. It includes an inverter and a voltage controller with up to seven batteries.

Although local defects in chloride-iodide-based perovskite are hard to avoid due to ion migration, a group of scientists have now found a way to passivate them. They used different combinations of 4-chlorobenzylammonium chloride and 4-chlorobenzylammonium bromide beneath the hole transport layer and reached up to 15% improvement in efficiency.

The Spanish company said that its new tracker “is designed for maximum adaptability to any terrain.” It works with all PV modules.

Researchers in Canada have created an experimental workbench for aboveground compressed air energy storage. Experimental data calibration reportedly ensured model accuracy with a mean absolute percentage error below 4.0%.

Egyptian researchers have developed a mini refrigerator powered by one to four thermoelectric units at varying voltages. They simulated and tested the system under different conditions, achieving a maximum coefficient of performance (COP) of 77.3%.

Scientists have measured two fixed panels and two single-axis modules for months to determine their site-specific heat dissipation factors. These local results indicate a 3.3% enhancement in energy production compared to the default factors used in PVSyst.

Trina Solar says it has supplied more than 1 GW of Vertex N 720W series panels for the Jinsha River project in China, with installation expected by year-end. The project aims to generate about 5.1 TWh of power per year.
