Zelenskiy said Russian overnight strikes hit energy infrastructure in four Ukrainian regions, cutting power to hundreds of thousands.

China's PV supply chain remains weak-stable as prices hold near cost floors and top‑down pass‑through is sluggish. Upstream polysilicon regions are entering the dry season, raising power costs; combined with earlier production cuts this has tightened supply and provided cost support for wafers. Wafer makers are curbing volumes to defend prices; mainstream N‑type wafer quotes are range‑bound, low‑price parcels are scarce and new export orders are limited. Integrated players are adjusting crystal‑pulling loads to need, inventories are structurally divergent and midstream destocking is slow. Downstream cell and module firms are prioritizing delivery of existing long‑term contracts; domestic installations are tepid and incremental overseas procurement is limited, squeezing mid/lower‑chain margins and weakening willingness to absorb high‑priced inputs. Market takeaway: cost inflation plus price discipline sustain support, but demand offers no clear upside; expect a short‑term stalemate with little material move in mainstream quotes across the chain.
