REC led the US residential solar panel market in the first half of 2025, while Tesla lost share in home batteries and inverters amid supply and policy pressures, according to EnergySage.

Tariffs, foreign content restrictions, and antidumping and countervailing duty investigations have reshaped the landscape for imports of solar components and manufactured products.

With U.S. domestic steel mills booked solid through 2025, a sudden doubling of tariffs on imported steel has created a critical bottleneck for American industries. The move, which hits specialized Indian steel particularly hard, is now delaying projects for builders and renewable energy developers who rely on steady, affordable supply.

Three US manufacturers actively working to commercialize their respective perovskite-silicon tandem technologies make the case for tandem modules. CubicPV, Caelux and Swift Solar argue a commercial future for perovskites is inevitable, and they tell pv magazine the current policy environment could work in the technology’s favor.

The US Federal Highway Administration (FHA) has warned that cellular radios have been found in unspecified foreign-made inverters and batteries used in PV highway infrastructure, according to Reuters. pv magazine speaks with cybersecurity expert Uri Sadot about the risks.

Nextracker has acquired US steel solar frame maker Origami Solar for $53 million, expanding into panel frame production to accelerate installations, support local supply chains and improve system durability.

Solar represented 75% of grid capacity additions in the first half, followed distantly by wind and natural gas, said new data from the Federal Energy Regulatory Commission.

Avaada Electro, the solar PV manufacturing entity of the Avaada Group, will unveil its n-type G12, G12R and M10L TOPCon solar modules at RE+ 2025, to be held in Las Vegas from September 8-11, 2025.

Accurately measuring the performance of perovskite solar cells and modules requires significant modifications to long-established testing standards used in silicon PV. Researchers are settling on methods that rely on up to several minutes of constant light exposure and other time-consuming procedures. These may be fine for the laboratory setting, but those looking to produce this technology at scale need standardized methods that can characterize cells and modules at a much faster rate.

The US Court of International Trade has ruled that the Biden administration’s two-year suspension of solar duty collections was unlawful, clearing the way for retroactive tariffs on billions of dollars of solar gear from Southeast Asia.
