Welspun New Energy signs 200 MW solar-plus-storage PPA with SECI
Welspun New Energy has signed a power purchase agreement (PPA) with Solar Energy Corp. of India (SECI) for a 200 MW solar project paired with a 400 MWh battery energy storage system (BESS).
New metric shows renewables are 53% cheaper than nuclear power
A new metric for assessing total system costs puts a least-cost mix of offshore wind and solar at about €46 ($54.20)/MWh in a future climate-neutral energy system for Denmark. Researchers tell pv magazine that figure is less than half the equivalent cost of nuclear under the same conditions.
Perovskite–silicon tandem solar cells using zinc-doped tin oxide achieve comparable performance to indium tin oxide counterparts
Fraunhofer ISE-led researchers demonstrated zinc-doped tin oxide (ZTO) as an indium-free alternative to indium tin oxide (ITO) for recombination layers in fully textured perovskite–silicon tandem solar cells. ZTO delivers comparable device efficiencies of 27–28% under current-matching conditions, offering a scalable, indium-free pathway for high-performance tandem photovoltaics without efficiency loss.
Vertical bifacial PV outperforms tilted PV systems in the UK
A year-long study in the UK finds vertical bifacial PV systems achieve an up to 26.91% higher output during morning hours compared to traditional tilted PV systems. The vertical bifacial system bettered the tilted system across all four seasons, with average power gains as high as 24.52% during winter.
Vietnam’s solar capacity surpasses 19 GW
Figures from the International Renewable Energy Agency state that Vietnam’s cumulative solar capacity reached 19,252 MW by the end of last year, indicating a 586 MW increase in 2025.
PV module prices continue to rise unabated
Photovoltaic module prices have risen for the fourth consecutive month, driven by strong demand for energy independence despite falling upstream costs such as polysilicon. At the same time, production cuts in China and tighter supply conditions are limiting availability, reinforcing price increases across all technologies.
How to generate hydrogen at home with recycled solar panels
Scientists in Chile have developed a low-cost, easy-to-deploy hydrogen system powered by end-of-life solar panels. The residential solution reportedly achieves a levelized cost of hydrogen of approximately $5.8/kg.
Silver demand from PV industry expected to drop 19% this year
A new report from Metal Focus reveals that global silver market remains structurally tight, with elevated prices, a fifth consecutive annual supply deficit in 2025, and ongoing mine and recycling constraints despite modest production growth. At the same time, PV-driven silver demand is falling sharply due to cost pressure and thrifting.
Solarport launches modular PV carport series
Solarport has launched the modular PowerPark PRO PV carport series, designed to meet UK/EU parking standards and adapt to various site layouts with multiple configurations and orientations.
Cyber threats for PV: What are ransomware attacks and how do they work
Ransomware attacks encrypt or lock critical PV system data and control platforms, preventing operators from accessing or managing their assets until a ransom is paid. These attacks can disrupt operations, reduce energy production, and create safety risks, making robust backups, segmentation, and incident response essential for resilience.
