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.
Optimising bifacial solar panels for floating PV applications in tropical freshwater
New research from India shows how bifacial solar modules should be deployed to achieve strong performance in floating PV projects planned on tropical freshwater. Their experimental setup demonstrated that higher efficiency gains are achievable by gauging panel height, water depth, and tilt angle.
Nanoparticles, phase-change materials in PVT systems
A team of scientists has used paraffin wax integrated with aluminum oxide and zinc oxide to improve the electrical and thermal performance of a photovoltaic-thermal system. They have also developed a prediction model for this specific combination of hybrid nano-phase change materials.
Research sheds new light on shade effects for rooftop PV
Researchers have covered part of a rooftop solar plant with varying numbers of shading cloth layers and continued to measure the power, current, and voltage of the system. They have been able to identify a point after which the value of system current and maximum power is no longer sensitive to shading heaviness.
PV module fault detection tech based on deep learning of electroluminescence
The novel technique is based on the VarifocalNet deep-learning object detection framework, which was reportedly tweaked to achieve quicker and more accurate results. Compared to other such methods, the new approach was found to be the most accurate and third quickest.
Atess releases 100 kW / 150 kW commercial inverters
Atess Power says it has developed 100 kW / 150 kW commercial inverters with two maximum power point trackers, a 600 V to 900 V battery voltage range, and 10 milliseconds on/off grid transfer capability.
Bslbatt launches storage system for C&I applications
Bslbatt says it has developed a new storage system for commercial and industrial applications, offering up to 241 kWh of capacity and supporting 100 kW or 125 kW of solar.
Griffith team reveals new method to calculate levelised cost of hydrogen
A team of researchers based in Queensland has incorporated overload capacity and power-dependent efficiency of the electrolyser in a novel techno-economic model to calculate the levelised cost of hydrogen.
