Polysilicon prices have fallen sharply over recent weeks due to persistent oversupply and weakening demand, briefly dipping to low levels before stabilizing slightly above CNY 50 ($7.31)/kg, though still near historical lows and below production costs. OPIS analyst Summer Zhang tells pv magazine that despite policy signals and potential future regulations, unclear implementation and continued excess capacity mean market conditions remain weak, with further demand declines and possible production cuts or discounted sales expected in the near term.

Battery swapping and fast charging are often positioned as competing solutions. In reality, they are responses to fundamentally different operational needs. 

In an industry where even a small fraction of a percentage impacts efficiency, it is critical to ensure that all cables used in solar energy applications are UV-resistant, halogen-free, and flame-retardant. This creates a strategic opportunity for domestic manufacturers with vertically integrated manufacturing capabilities, sophisticated quality control programs, and a commitment to sustainability.

IT security firm Jakkaru has identified a vulnerability in microinverters from AP Systems that could enable a “kill switch” scenario, potentially shutting down tens of thousands of inverters simultaneously and disrupting grid operations.

Tata Power has announced the enterprise-wide adoption of the Databricks platform to accelerate its data and AI transformation, aiming to improve operational efficiency, decision-making, and digital innovation across all its business clusters.

Premier Energies Ltd has received orders worth INR 2,577 crore in Q4 FY 2026 for the supply of 1.6 GW of solar cells and modules. The orders are scheduled for execution across FY 2027 and FY 2028.

Renalfa Power Clusters plans to combine newly acquired solar and battery assets in Romania into a hybrid project using lithium-ion and sodium-ion storage.

For decades, the “energy trilemma” – balancing energy security, affordability, and environmental sustainability – has shaped how nations think about energy strategy. For much of the Global South, it has served as a practical compass. But today, that compass may no longer be sufficient.

The Dutch research institute has presented what it describes as the world’s first perovskite-based roof tile, achieving up to 13.8% efficiency on standalone modules and 12.4% when installed on a curved surface. The flexible modules were produced using TNO’s experimental roll-to-roll platform,

A new sodium-ion cell for ESS may further improve competitiveness in large-scale systems against the weight of the lithium-ion battery sector.
