Envertech launches microinverters for PV systems with up to 60 modules
Envertech says it has developed microinverters for PV systems supporting up to 60 modules, allowing up to four modules per unit with separate maximum power point tracking.
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.
China connects first large-scale flywheel storage project to grid
The 30 MW plant is the first utility-scale, grid-connected flywheel energy storage project in China and the largest one in the world.
Lightweight ventilated BIPV system for low-load rooftop applications
Scientists in China have designed a ventilated building-integrated photovoltaic system that relies on flexible solar modules with a weight of 6 kg/m2. The system also uses an airflow channel under the PV panels to reduce their operating temperature and increase their power yield.
Envision pushes energy storage density to new highs with 8 MWh, 20-foot container
Chinese multinational Envision Energy has unveiled the world’s most energy dense, grid-scale battery energy storage system packed in a standard 20-foot container.
Singapore progresses its 4 GW clean energy import ambition with new agreements
Singapore has progressed its ambition to import 4 GW of low-carbon electricity by 2035 from neighbouring countries, which includes from Australia’s SunCable project, with the signing of two new agreements.
Aiko promises more energy output in less space with n-type 470 W solar panel
Chinese solar manufacturer Aiko has achieved Clean Energy Council approval for its 470 W Neostar 2P solar panel, which boasts more power output in less space, with an added shade optimisation advantage.
All-perovskite tandem solar cell based on tin-lead perovskite achieves 28.8% efficiency
Conceived by Chinese scientists, the cell was built with new surface reconstruction strategy based on the use of 1,4-butanediamine (BDA) and ethylenediammonium diiodide (EDAI2) as surface modifiers. The device was able to retain 79.7% of its initial efficiency after 550 h.
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.
