Scientists build 42.01%-efficient indoor PV cell for self-powered devices
International researchers have included an interlocked self-assembled monolayer in perovskite indoor PV to enhance its stability and durability, testing the novel structure through fabricating cells, mini modules, and a prototype device of an electronic price tag, and which was found to exhibit a lifetime approaching 6,000 hours.
Solar module fault diagnosis uses convolutional neural network
Researchers in China have created a dataset of various PV faults and normalised it to accommodate different array sizes and typologies. After testing the new approach in combination with the 1D-CNN machine learning technique under different conditions, they found an accuracy of more than 99%.
Electric vehicle fleet delivery routes optimised to find local surplus solar
Scientists in Japan have developed a model that predicts surplus solar generation and creates a route for optimised charging of electric delivery vehicles, defining their work as a practical blueprint for logistics operators.
DMEGC releases new series of residential all-in-one storage systems
The Chinese company stated that its new H02 product line is available in either single-phase or three-phase configurations. It comes with a different number of 5.12 kWh batteries.
Wireless electric vehicle charging tests improve efficiency by 88%
Scientists in India have simulated and tested a prototype wireless charging system for electric vehicles, with a three-port DC–DC converter at its core and have found it achieved an improved efficiency of 88%.
K2 Systems unveils new pitched roof mounting solutions
K2 Systems has introduced two new pitched roof mounting components for residential solar: the SingleHook 3S Light, made of aluminum and stainless steel; and the InsertionRail 2.0, an aluminum mounting rail.
Deye launches C&I power conversion system with battery storage
Deye has developed a new power conversion system optimised for solar integration, with modules ranging from 100 kW to 125 kW. The Chinese manufacturer says the PCS supports flexible system design and targets commercial and industrial applications.
How albedo interacts with rooftop PV system patterns
Researchers have simulated 160 cases of PV rooftop installation in southern and northern Italy. Among changing parameters were size and type of the panels, as well as their roof cover rate. The considered albedos were 20%, 40%, 60%, and 80%, representing different types of roof materials.
The best tilt angle to improve PV system performance on low-income housing
Researchers have demonstrated that the theoretical optimal tilt for rooftop solar energy production in low-cost buildings in Nigeria is approximately 5.67°. Their modeling suggests to adopt south-facing roofs for PV generation in the southern hemisphere.
GoodWe releases 112 kWh storage system for C&I solar
GoodWe has launched a 112 kWh battery energy storage system for commercial and industrial solar projects, featuring 96% round-trip efficiency and a 6,000-cycle lifespan. The system allows parallel connection for up to 450 kWh of total capacity.
