Scientists from Singapore have designed new floating breakwaters integrating wave energy converters that can be used to reduce the impact of waves on offshore PV systems. Their analysis showed that the wave energy systems can achieve the highest additional power output when the wavelength is shorter.

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.

Conceived by French scientists, the novel system uses ensemble learning and does not require anything more than a commercially available optimizer. Before it makes a decision, the method combines K nearest neighbors, support vector machine, and decision tree learning. Accuracy is reportedly up to 89%.

Researchers have covered part of a rooftop solar plant with a different numbers of shading cloth layers to measure their power, current, and voltage. 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.

Scientists in Mexico have conceived a new solar module cooling tech that can reportedly improve PV power generation by up to 2%. The system uses nanofluids embedded in an aluminum single-channel attached to the back of the panel.

Scientists have tested several machine-learning algorithms to predict the optimal tilt angle (OTA) of solar projects in 37 Indian cities, leading to improvements of up to 90%.

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.

Scientists used a year’s worth of data from East China to analyze what weather conditions affect abnormal, high, and low PV output days. They also constructed a simple extreme output prediction model and examined the atmospheric circulation anomalies corresponding to extreme output events.

An international research team has developed a closed-loop PV cooling system that can reportedly offer 24-hour continuous operation. The system is claimed to be particularly suitable for hot and arid regions and to improve the lifespan of solar panels by up to 8.2%.

Conceived by scientists in Japan, the system consists of a a xenon flash lighting system and a detector capacitor. It can reportedly examine solar modules and find the degraded ones without disconnecting the string’s electrical wiring.
