Powerchina switches on 100 MW solar tower in South Africa
Powerchina has switched on a 100 MW solar tower in South Africa. The concentrated solar power (CSP) project will supply 480 GWh of clean energy to the country’s power grid each year. The system’s molten salt storage enables 12 hours of full-load operation.
Semi-online tech for short-term solar irradiance forecast in PV plants
Scientists in Spain have created a semi-online technique to predict solar irradiance at different locations inside a photovoltaic plant. The proposed training approach is described as suitable for highly variable time series forecasting.
Trina Solar presents ‘fully recyclable’ 645 W PV module with 20.7% efficiency
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.
Maxeon challenges Nasdaq delisting threat, plans reverse stock split
Maxeon has challenged Nasdaq’s decision to potentially delist it from the Global Select Market and is now implementing a reverse stock split to raise its bid price above the required threshold. A hearing on the matter is pending.
Offgrid hybrid PV-biogas system for residential applications
The system was conceived to respond to Lebanon’s energy crisis and help homeowners become independent from grid electricity. Biogas production is used when PV power generation is insufficient and machine learning techniques help the system predict solar energy production.
Livoltek launches 120 kW EV chargers
China’s Livoltek says it has developed 120 kW electric-vehicle chargers with 140 kW input and a 100 kWh LFP battery, supporting the CHAdeMO, GB/T, CCS1, and CCS2 standards.
Platio debuts new walkable solar panels
The Hungarian company said its new products can handle a load of 300 kg. The modules are available with power outputs of 23.65 W and 59.68 W and can be integrated with wood-plastic composite, wood, stone, or ceramic floorings.
Computer vision for real‑time shadow detection in PV systems
Scientists have developed a novel method that uses live video feed to detect shadows on solar panels. It uses computer vision techniques, such as gamma transform and histogram matching, resulting in performance that is reportedly better than conventional techniques, especially in large arrays.
EU-funded project seeks set up pilot production of large-area perovskite PV modules
The EU-funded Laperitivo project aims for 22% efficiency in 900 cm² opaque perovskite modules and 20% efficiency in semi-transparent ones. The project partners include imec, Fraunhofer ISE, TotalEnergies, and EDF.
Researchers develop lithium-sulfur battery that can be cut, folded
By coating the iron sulfide cathodes in polymers, a research team was able to create transition-metal sulfide-based lithium batteries with stable cycling and high safety. After 300 cycles, a lithium carbide iron disulfide pouch cell retained 72.0% capacity with no capacity degradation after 100 cycles.
