Researchers analyze wind cooling effect for 5.9 MW rooftop PV array
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.
2D modeling to deploy bifacial PV plants with single-axis trackers on sloping terrain
Developed by Spanish scientists, the proposed model is intended to reduce yield losses caused by the fact that north-south aligned single-axis trackers are often deployed on uneven east-west slopes.
Mitigation strategies against islanding in grid-connected PV systems
Researchers in India have proposed a new set of techniques to mitigate total harmonic distortions during islanding events, which occur in distributed generation systems when there are disruptions in the power grid. Compared to conventional approaches, it reportedly achieves faster detection times by leveraging real-time data analytics and dynamically adjusting to changing grid conditions.
European team targets 20%-efficient perovskite modules using industrial processes
The LUMINOSITY project consortium aims to develop 20%-efficient metal halide perovskite prototype modules measuring over 900 cm², designed for a 20-year lifespan and compatibility with roll-to-roll (R2R) processing.
Solinteg launches new residential solar storage systems
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%.
Flexible printed solar film research tacks closer to commercial viability
Australia’s scientific research agency CSIRO has taken its pilot-scale production of flexible printed solar film to a new level following the official launch of the new Printed Photovoltaic Facility in southwest Melbourne, Victoria.
Perovskite solar cell built with slot die coating achieves 19.17% efficiency
A team from Jeonbuk National University in South Korea used slot die coating (SDC) to produce uniform high-quality perovskite films, which they used in a perovskite solar cell that achieved 19.17% efficiency and lab cell-sized modules that achieved 17.42% efficiency.
Ultra-short-term PV power forecast based on dung beetle algorithm
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.
Bluetti launches new ESS with up to 154.8kWh of storage
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.
New sun simulator, light-soaking tools for perovskite solar cells, modules
MBJ Solutions, a German testing equipment specialist, recently launched two new products for developers of perovskite and perovskite silicon tandem devices. The MBJ Steady State Sun Simulator is designed for cells and small perovskite module research, and the MBJ Light Soaking Unit is for aging tests and preconditioning.
