JinkoSolar Slashes Older Capacity in Haining as Insiders File to Sell and the Stock Hits a Fresh Low
Published on 10/01/2026 at 15:11 | Editorial boerse-global.de
JinkoSolar is shrinking its way through the solar industry's brutal downcycle. Rather than chase another round of gigawatt records, the Chinese manufacturer is retiring older production lines at its Haining site and replacing them with smaller, more advanced ones — a striking reversal for a sector that spent years treating volume as the only scoreboard.
According to the Jiaxing environmental authority, a technological conversion project at Haining was slated for approval on September 21. The plan calls for scrapping annual capacity of six gigawatts each for solar cells and modules, and installing just 2.7 gigawatts of cell capacity and four gigawatts of module capacity in their place. The message is hard to miss: efficiency and conversion rates now matter more than raw output.
Field Data Backs the Efficiency Bet
Small technical edges can carry outsized weight in punishing conditions. A field test in Qatar, run from July 7 to August 22, found that the company's own Tiger Neo 3.0 modules delivered a 2.01 percent gain in power generation in high-irradiance areas.
Hardware alone, though, won't secure sales. JinkoSolar is pairing its latest-generation modules with the SunGiga G2 commercial storage system in a package called Sunny 365, aimed squarely at small and midsize manufacturers that want a more dependable energy supply.
The storage push extends beyond product bundling. China's Quality Certification Centre has authorized the company's in-house testing center as a certified laboratory for the energy storage sector, and roughly three weeks earlier the storage unit signed a distribution agreement in the Middle East.
Should investors sell immediately? Or is it worth buying JinkoSolar?
Insider Filings Land on a Nervous Market
Sentiment, however, is being pulled in the opposite direction. Regulatory filings with the U.S. Securities and Exchange Commission have disclosed planned share sales by major holders and board members — the kind of signal traders tend to read as a warning light, especially with the solar industry wrestling with overcapacity and heavy price pressure.
On September 22, major shareholder Zhuoling International Limited flagged its intention to dispose of 700,000 American Depositary Shares, with the document signed by JinkoSolar director Kangping Chen. A day later, fellow director Siew Wing Keong filed a notice to sell 45,000 ADSs.
Weak quarterly results and a trimmed outlook are widely seen as the main driver behind the share price decline, as competition keeps eroding the profitability of module manufacturing.
A 63 Percent Slide and a New 52-Week Low
The accumulation of negatives is written plainly in the chart. The stock has lost 63 percent since the start of the year. On Tuesday it touched a new 52-week low of EUR 8.08 before trading at EUR 8.47 in today's session.
Legal noise has been added to the operational strain. U.S. law firm Pomerantz launched an investigation on Tuesday into potential securities law violations targeting the company and individual executives, triggered by second-quarter 2026 business figures. The probe is explicitly a preliminary inquiry by a law firm, not a judicially established finding of wrongdoing.
Meanwhile, management is preparing an organizational overhaul at the group level. The established ticker symbol JKS will remain unchanged on the trading venues.
In a phase where capacity is being cut back and margins defended from scratch, insider transactions carry double weight with market participants. The shift from mass production toward a highly specialized niche is in full swing — and it is demanding painful discipline from the industry's heavyweights.
