On May 23, the winning bidder candidates for the inverter replacement project of Fengshou PV Power Station (Phase I) were announced. Sungrow Power Supply Co., Ltd. ranked first among the winning bidder candidates, with a bid price of RMB 15.2797 million yuan. Fengshou PV Power Station was invested and constructed by Guangxi Xiangzhou Hanggui Energy Co., Ltd., and is located at Fengshou Reservoir between Shilong Town and Maping Town in Xiangzhou County, Laibin City, Guangxi. The PV ground power generation project with an installed capacity of 60MWp for Fengshou PV Power Station (Phase I) was connected to the grid in June 2017. The system of Fengshou PV Power Station (Phase I) mainly consists of key equipment such as PV modules, string inverters, AC cabinet step-up transformers, and AC/DC cables. The string inverters used are equipment produced by Sungrow Power Supply Co., Ltd., with the specification and model SG50KTL and a quantity of 1,165 units. The maximum DC voltage of the SG50KTL string inverter is 1,100V, with a rated output voltage of 540V, a rated output power of 48kW, and air cooling. Among them, 384 SG50KTL string inverters use RS485 for communication, while 781 SG50KTL string inverters use PLC (Power Line Communication) for communication.

[SMM Silicon-Based PV Morning Meeting Summary: Wafer Prices Drop Back Slightly, Overall Solar Cell Prices Continue to Decline] The market price of N-type 18X wafers is 0.93-0.95 yuan/piece, and the price of N-type 210RN wafers is 1.05-1.1 yuan/piece. The price of high-efficiency PERC182 solar cells (with an efficiency of 23.2% and above) is 0.275-0.295 yuan/W, and the mainstream quotation for Topcon183 solar cells (with an efficiency of 25% and above) is around 0.255-0.26 yuan/W. The mainstream transaction price for Topcon210RN is 0.265 yuan/W, with a quotation range of 0.26-0.27 yuan/W. The price of Topcon210 solar cells is around 0.275-0.28 yuan/W.

[SMM Analysis: Aluminum Prices Fluctuate at Highs with Weakening Demand Rigidity, and PV Frame Operating Rates Continue to Decline] This week, the operating rates of sampled PV frame enterprises continued to diverge. The operating rates of some leading enterprises in east China dropped to 70%. According to the SMM survey, some small and medium-sized enterprises in Anhui reported that their PV frame orders were mainly from existing long-established customers, and they had suspended taking orders from new customers. Meanwhile, the operating rates of small and outsourced enterprises in east China and Henan remained at a low level of 40%.

[SMM Weekly Review: Polysilicon Prices Weakened as Month-End Transactions Unfolded, with 210RN Cell Prices Testing Increases] This week, the price index for N-type polysilicon was 35.4 yuan/kg, with N-type recharging polysilicon priced at 35-38 yuan/kg and N-type mixed polysilicon at 31-36 yuan/kg, indicating a decline in polysilicon prices. Market transactions gradually picked up this week, with polysilicon prices ultimately falling in this round of order signing, and the price drop for mixed polysilicon was more pronounced. The average price of some orders containing broken materials fell below 30 yuan/kg. High-quality dense recharging polysilicon remained relatively resilient, with some orders holding firm at 35 yuan/kg after negotiation. There may still be orders signed subsequently. Currently, there are signs of stabilization in the wafer and cell sectors, which may provide some support for polysilicon prices (especially high-quality materials). However, some manufacturers' mixed polysilicon containing broccoli and coral materials may still have some room for downward adjustment.
