Researchers analyse wind cooling effect for 5.9 MW rooftop PV array
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 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%.
Bluetti launches new ESS with up to 154.8kWh of storage
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.
New passivation strategy increases efficiency of chloride-iodide-based perovskite solar cells by 15%
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.
PV Hardware unveils solar tracker
The Spanish company said that its new tracker “is designed for maximum adaptability to any terrain” and is compatible with all PV modules.
Solis introduces low-voltage hybrid inverters
The Chinese manufacturer said that its new series includes inverters with up to 15 kW of AC output. It supports a maximum input current of 20A.
SolarEdge unveils inverters for smaller solar projects
SolarEdge has unveiled its new TerraMax Inverter, which boasts 99% efficiency and enables 200% DC oversizing. It features an integrated night-time PID rectifier and is paired with the company’s H1300 Power Optimisers.
Building-integrated PV system integrates PCM on sides
Scientists have designed a new building-integrated PV system that uses 30 mm of phase change material on each side of the wall. The array reportedly achieved superior thermoelectric coupling performance compared to reference BIPV systems without PCM.
Trina Solar presents ‘fully recyclable’ 645 W PV module
Trina Solar claims it has developed the world’s first “fully recyclable” 645 W PV module with 20.7% efficiency. It made the panel with interlayer separation reagents, chemical etching technology, and wet chemical silver extraction tech.
New deep learning tech uses electroluminescence images to identify defective PV cells
The novel method uses the YOLOv8 framework, integrating an attention mechanism and a transformer model. It was tested on a dataset of 4,500 electroluminescence images against several other models and its results were up to 17.2% more accurate.
