Scientists have placed four PV panels in a 21-metre wind tunnel and run different tests regarding tilt angles, mounting height, spacing, and incoming flow direction. They found that when the spacing between panels exceeds twice the panel height, the mutual influence on dust deposition becomes negligible.

Scientists have quantified the impact of wildfires on the availability of direct normal irradiance and global horizontal irradiance at the state, regional, and national levels in the United States. They have found that direct irradiance is more sensitive to smoke than the PV-relevant global horizontal irradiance.

The pacific island nation of Tuvalu is on track to achieving its goal of 100% renewables by 2030, with the recent commissioning of a 500 kW rooftop solar project and 2 MWh battery energy storage system in it’s capital Funafuti.

Enphase Energy has released new software to help homeowners install larger solar and battery systems without major electrical panel upgrades. It uses real-time measurements from current transformers to make immediate decisions.

Scientists in Egypt have created an anti-soiling coating for solar panels by mixing ethanol, deionized water, ammonium hydroxide and tetraethyl orthosilicate. They tested a coated panel outdoors for ten months and found that the panel showed a 64.7% higher current compared to reference modules without coating.

A Chinese-Italian research team has analysed the influence of different tilt angles on the thermal failure of the photovoltaic facades or roofs in fire conditions, finding that when the tilt angle exceeds 30 degrees, the time to failure increased significantly.

Researchers have analysed how wind speed and direction affect the cooling of a rooftop PV plant with 10,806 panels. They said 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%.

United States-based Bluetti has developed a new energy storage system 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 from the University of New South Wales has found a way to passivate them. They used different combinations of 4-chlorobenzylammonium chloride and 4-chlorobenzylammonium bromide on top of the hole transport layer and reached up to 15% improvement in efficiency.
