Summary · why it matters
On September 11, Sungrow, a global leader in solar and energy storage, sent a product price adjustment notice to downstream customers, announcing that starting September 20 it will raise prices for photovoltaic inverters, energy storage converters, and energy storage systems by 5% to 15%. A reporter from The Paper confirmed with a relevant person in charge of Sungrow's power energy storage product line that the main reason for the price increase is the rise in bulk material prices such as copper and aluminum, and secondarily to curb vicious low-price competition. Sungrow stated that the magnitude of upstream material price increases in this round has continued to exceed expectations, and existing product pricing can no longer cover the comprehensive investment in raw materials, manufacturing, technology iteration and upgrades, as well as after-sales operation and maintenance. This is not Sungrow's first price increase this year. In the first quarter, it and other inverter leaders such as Ginlong Technologies took the lead in raising prices for energy-storage-specific models by 6% to 10%. Since July, more than ten companies along the industry chain, including EVE Energy, Sinexcel, and Inovance Technology, have intensively issued price adjustment notices covering battery cells, converters, and solar-storage-charging equipment, with increases ranging from 5% to 30%. Cost pressure comes from multiple sources: lithium carbonate prices rebounded from a low point of less than 60,000 yuan per ton in mid-2025, and once exceeded 210,000 yuan per ton in June 2026, a cumulative increase of more than 200%. The surge in AI computing power has squeezed wafer production capacity, and prices of key components such as memory chips and IGBTs have generally risen by between 50% and 800%. Tian Qingjun, senior vice president of Envision, expressed opposition to vicious price competition and pointed out that planned capacity expansion for energy storage cells in the industry this year has already exceeded 800 gigawatt-hours, with completed capacity by the end of the year expected to be about 1.2 to 1.5 terawatt-hours, and total planned capacity approaching 2 terawatt-hours, far exceeding real global market demand. At present, price increases along the industry chain are mainly driven by rising costs, and whether the price increases can be accepted by downstream project owners still needs to be observed by the market.
