Recently, companies including Sungrow Power Supply and Kstar New Energy have successively issued price adjustment notices covering products such as solar photovoltaic (PV) inverters, energy storage power conversion systems (PCS), and energy storage systems, with price hikes reaching up to 20%.
On September 11, Sungrow Power Supply issued a "Notice of Product Price Adjustment." The company cited market drivers such as rising upstream raw material prices and escalating supply chain costs. Prices for non-ferrous metals—including copper, aluminum, tin, silver, and gold—have continued to climb, which, coupled with tightening supplies of core components, has pushed overall procurement costs steadily higher. To ensure stable and reliable product quality, keep delivery schedules controllable, and avoid compromising product performance, delivery timelines, or service quality due to cost-cutting, the company decided to make moderate price adjustments across relevant products.
According to the notice, effective September 20, 2026, prices for Sungrow's PV inverters will be increased overall by 5% to 15%; energy storage PCS will rise by 5% to 10%; integrated storage-PCS units will increase by 10% to 15%; and prices for both the PT series (utility-scale energy storage systems) and PS series (commercial and industrial energy storage systems) will be raised by 5% to 10%.
The notice specified that orders with finalized contracts and formal submissions will still be executed under original contracts and quotes. However, new contracts signed and new orders placed on or after September 20 will be subject to the updated pricing.
Earlier on August 20, Kstar New Energy also released a "Notice of Price Adjustment for New Energy Products." The announcement stated that, affected by recent global market conditions, upstream raw material prices have continued to climb, and core material supplies have tightened. Despite ongoing internal cost-reduction efforts, the existing price structure could no longer support normal business operations and stable product delivery. Consequently, the company decided to moderately raise prices for its new energy products effective immediately, with adjustments ranging between 10% and 20% depending on the model. Specific price adjustment details are being communicated and confirmed directly with customers by sales managers.
According to incomplete statistics, since July 2026, at least eight companies—including East Group and EVE Energy—have successively issued price adjustment notices. These adjustments cover sales prices across products such as cathode materials, energy storage battery cells, power conversion systems (PCS), solar-storage-charging equipment, residential energy storage, energy storage microgrids, and EV charging equipment, with price adjustment margins ranging from 2% to 30%.
