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.

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.

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 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 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.

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.

Chinese electronics manufacturer Anker has developed a new all-in-one home storage solution with up to 30 kWh of capacity, available in single-phase and three-phase configurations.

GoodWe has developed new double-glass tunnel oxide passivated contact (TOPCon) bifacial solar modules for its Polaris series, available in 530 W and 580 W variants.

Japan’s Leapton Energy has developed a 20.48 kWh residential battery energy storage system featuring storage capacities starting at 5.12 kWh, utilising lithium iron phosphate technology.

The Chinese manufacturer said the new product has an efficiency of up to 19.46% and a temperature coefficient of -0.30% per C. It is available in bright red, light gray, brown, green, blue-green, orange, and ocean blue.
