Hongyuan rolls out 40 µm ‘engineering-ready’ ultra-thin silicon wafers
Hongyuan Green Energy says it has produced a first batch of 40 µm monocrystalline silicon wafers that support full-size and half-cut formats, with slicing completed using the company’s in-house wafering equipment.
RheEnergise commissions first ‘high density hydro’ long-duration storage in UK
Pilot long-duration energy storage (LDES) project uses low viscosity, denser-than-water fluid. RheEnergise is panning for future projects in 10 MW to 100 MW range, with six to 20 hours of storage capacity.
Scientists unveil hybrid-energy heat pump combining absorption and compression cycles
Researchers in Hong Kong have developed a hybrid-energy heat pump that seamlessly combines absorption and compression cycles using crystallization-free ionic liquids, improving efficiency and reliability across varying solar conditions. Simulations in multiple Chinese cities show the system can significantly cut electricity use and cooling costs, making it promising for sustainable building cooling and future commercial scaling.
Sigenergy secures top position for multiple storage markets as installer adoption accelerates
SunWiz market data ranks the manufacturer as the top energy storage supplier in Australia, Ireland, and South Africa.
How to combine C&I solar with compressed air energy storage
Researchers have studied the potential of combining photovoltaic systems with compressed air energy storage (CAES) to power a commercial building in South Africa. They found that a co-optimized system could lower total capital costs by 15–20% compared to traditional sequential sizing approaches.
Serbia installs 134.3 MW of solar in 2025
Serbia had a record year for solar additions in 2025, led by deployment of large-scale plants. The country has a gigawatt-size project pipeline, although most remain in the earlier stages of development and are not expected to come online this year.
Fraunhofer ISE developing world’s first medium-voltage solar plants
Germany’s Fraunhofer Institute for Solar Energy Systems (Fraunhofer ISE) is developing the world’s first medium-voltage PV plants in Germany to cut material use, reduce costs, and simplify grid integration. They will test 1,500 V and 3 kV string configurations to create cost-effective, voltage-resistant components for large-scale solar.
Analysts warn of possible, sudden silver price fall
pv magazine has spoken with silver analysts from Bloomberg and StoneX about the vertiginous growth of silver prices in recent weeks. They both agree that when prices rise too fast, investors’ behavior may change quickly. Meanwhile, the price of the precious metal has reached another all-time high today at $110 per ounce.
France installs 5.9 GW of PV in 2025
The country’s cumulative installed PV capacity reached 31.1 GW at the end of December.
