A scientist in Turkey has simulated eight PV-supported hybrid atmospheric water harvesting systems and compared their performances. They were all considered to operate with R1233zd(E), R1234yf, and R600a, as well as R32 refrigerants. The required PV system size was as low as 20 m2.

Researchers in India say that photovoltaic-thermal (PVT) systems offer greater performance stability than conventional PV systems in hot climates. Using irradiance and temperature data, the team applied a Random Forest model that predicted efficiency classes with 97% accuracy.

Scientists in Germany have collected dust from Qatar, Morocco and Thailand to analyze the impact on the performance of uncoated solar glass and uncoated PV mini-modules. Their analysis has shown that dust coverage could range from 4% to 60%.

Researchers in the Netherlands have identified all major solar power plants in the Dutch Province of Gelderland and have analyzed all of their spatial measures in an effort to assess their impact on landscape. They have specifically focused on land use competition, biodiversity, and landscape experience.

Researchers in Saudi Arabia have developed a hydrogel composite that absorbs moisture in solar modules overnight and facilitates evaporative cooling throughout daylight hours. The system has undergone lab tests and outdoor experiments on two continents.

Researchers in Spain have developed a new method to estimated potential-induced degradation (PID) in solar modules used in PV-driven water pumping systems. The proposed approach can detect PID from the open-circuit voltage measurement of the system’s PV module strings.

Scientists have placed mist nozzles inside a bifacial PV module and measured it under an extremely hot climate. The module was found to generate up to 37% more electricity on sunny days and up to 46% more on cloudy days compared to standard monofacial panels.

Scientists in Qatar have outlined a new approach to optimize residential bifacial PV systems by combining south-facing and vertically mounted east-facing configurations. The novel methodology reportedly results in a 21.6% increase in a system’s net present value.

Scientists have developed a system that harvests rainwater running off PV panels for household use or hydrogen production. Their analysis showed that, in the southern Sahel, the system can meet both the energy and water requirements for electrolysis, with surplus rainwater covering up to 50% of a household’s daily water demand.

The Portuguese company said its new anti-soiling solution lasts for at least a year. It can be applied during routine cleaning operations by mixing it directly in the cleaning water.
