FLAT GLASS (06865) saw its stock price plummet by 5.19% during Friday's trading session, reflecting a broader downturn in the solar energy sector. The sharp decline comes as the industry grapples with false rumors, declining installation rates, and uncertainties about future profitability.

The solar industry has been under pressure, with several key players experiencing significant drops. FUYAO GLASS (03606) fell 4.89%, XINTE ENERGY (01799) declined 4.64%, and XINYI SOLAR (00968) dropped 3.8%. These movements indicate a sector-wide challenge rather than company-specific issues for FLAT GLASS.

Industry concerns have been fueled by false rumors about a polysilicon storage platform, which were later debunked by insiders. Additionally, the solar association clarified that a rumored "three-day meeting" was actually just a regular monthly gathering. More substantially, the sector is facing headwinds from declining installation rates, with August's newly installed photovoltaic capacity in China dropping by 55.29% year-on-year and 33.33% month-on-month to 7.36GW. Guosen Securities suggests that future profitability for solar companies will largely depend on capacity clearance rates and market-driven pricing for solar electricity installations, adding another layer of uncertainty to the industry outlook.
