N-type silicon sees first price drop of the year

March 27, 2024

N-type silicon sees first price drop of the year
The transaction price of n-type granular silicon has dropped for the first time since the start of this year, revealing changing supply and demand dynamics in the upper stream of the solar sector. This week saw a general decline in polysilicon prices compared to March 13th, as per the data released by China’s Silicon Branch. Notably, n-type granular polysilicon witnessed its first drop of the year, falling by 1.94%. While p-type polysilicon prices remained steady, there was a slight shift in transaction focus towards lower prices. Polysilicon Type Price Range (CNY/kg) Average Price (CNY/kg) Average Price (USD/kg) Weekly Change (%) N-Type Granular Silicon 60-63 60.8 8.44 -1.94% Mono Recharge 55-64 62.8 8.71 0% Mono Dense 53-62 60 8.31 0% Mono Popcorn 50-59 55.9 7.74 0% Insights from Solarbe suggest that the polysilicon market this week was relatively quiet, with some orders still pending. The recent price inversion between n-type and p-type wafers has led to increased demand for high-quality p-type polysilicon. However, polysilicon manufacturers have yet to adjust prices, resulting in limited transactions and a gradual buildup of inventory. Expectations for future price reductions are high. Wafer Prices Drop This week, wafer prices experienced an overall decline. Faced with significant inventory and cost pressures, some wafer manufacturers have started adjusting their production schedules. Feedback from industry players indicates that accumulated wafer inventory has reached 4 billion pieces. Despite a gradual recovery in demand, there is a noticeable downward trend in wafer transaction prices. Cell, Module Prices Steady Prices for cells and modules remained stable this week. In recent tender projects, some module manufacturers have tried to increase prices. However, overall, sustaining continuous price hikes for modules is proving challenging. As we move into the second quarter and temperatures rise, the gradual roll-out of large-scale ground-mounted projects in China is expected to significantly boost market demand, positively impacting prices across the entire industry chain. If you are looking for photovoltaic modules with high cost-effectiveness, please feel free to consult Rongstar Energy.

TOPCon cells pare loss while wafer prices drop on inventory pile-up

March 18, 2024

TOPCon cells pare loss while wafer prices drop on inventory pile-up
Polysilicon With manufacturers still delivering previous orders, polysilicon prices were flat in mid-March, mostly sitting at RMB 64-69/kg. Buyers need to use polysilicon of varying purity. Still, there were some order inquiries, but negotiations were in standstill as both buyers and sellers remained cautious towards prices. Given the rising wafer inventory level, future adjustments of ingot manufacturers’ utilization rates, and price-talk deadlock, whether trading prices have declined will not be determinable until late March. Polysilicon inventory experienced a month-on-month increase. A more pronounced inventory problem will gradually emerge in the second quarter.  Wafer Wafer inventory kept increasing to 3.3-3.5 billion pieces this week, with n-type 182mm wafers accounting for the majority. Sales pressure amounts due to the persistently high production plans and continuous inventory accumulation, resulting in rapid wafer price drops. While some manufacturers were still delivering previous orders, average prices had declined and may continue falling next week. Trading prices dropped this week to RMB 2/piece, RMB 2.68-2.7/piece for p-type M10, G12 wafers, and RMB 1.85-1.9/piece, RMB 3/piece for n-type M10, G12 ones, respectively. Each saw a 2-5% decline. The wafer sector now sees a gloomy outlook as polysilicon prices held steady temporarily, staying high for n-type-ingot-use materials due to order delivery problems. On the other hand, prices slumped as wafer inventory continued rising, eroding earnings. Against these backdrops, manufacturers planned production cuts, of which the effect will not be noticeable until the first half of April.  Cell For p-type cells, trading prices remained at RMB 0.38-0.40/W for M10 and RMB 0.37-0.39/W for G12 cells this week. Prices for n-type M10 cells were relatively stable, averaging RMB 0.46-0.47/W and reaching RMB 0.48/W for ultra-high-efficiency ones. The price gap between TOPCon and PERC cells stabilized at RMB 0.08-0.09/W. G12 HJT high-efficiency cells saw prices coming in at RMB 0.6-0.7/W. With wafer prices plummeting, increases in cell prices will lose momentum despite manufacturers’ recent attempts to offer higher price quotes. Still, the profitability of n-type TOPCon cells recovered. Future price trend of cells will largely depend on whether module prices increase or not.  Module Trading prices for modules stayed still this week at RMB 0.85-0.9/W, RMB 0.88-0.96/W, and RMB 1.04-1.25/W for PERC (glass-glass), TOPCon, and HJT modules, respectively. Module manufacturers kept attempting to offer higher price quotes, which seems unlikely as some still deliver previous low-price orders below RMB 0.85/W, indicating inconsistency among their strategies. Hence, module prices will hold steady in March, with the low-price range slightly picking up. Recently, leading manufacturers have cut shipments for orders below RMB 0.88/W, potentially facilitating future price hikes.   For more solar news and solar products needs, please click www.rongstar.com

N-type modules secure 70% in Jan-Feb tenders, prices down 51%

N-type modules secure 70% in Jan-Feb tenders, prices down 51%
N-type solar modules have emerged as the dominant choice in tenders during January and February in China, comprising over 70% of the market share. This shift has been accompanied by a substantial 51% drop in module prices over the past year. The industry landscape has witnessed noteworthy signals as we step into 2024. Factors such as a slight uptick in polysilicon costs and lower production rates during China’s New Year holiday have prompted solar module manufacturers to hint at potential price rises. This trend was validated in recent bids where n-type module prices have increased by CNY 0.03-0.04/W compared to pre-holiday rates. However, with production resuming in March, the industry foresees a minor downward trend in supply chain prices. Examining the tender data in January and February, p-type module prices fluctuated between CNY 0.85-0.92/W. Meanwhile, n-type bids displayed a broader range, varying from CNY 0.89-0.98 CNY/W, down about 50% year-on-year. N-type dominance and shifting demand In the first two months of 2024, over 67 GW of tenders have revealed results. About 8 GW was allocated to individual projects and the remaining 60 GW for framework procurement. Key players like China Petroleum and China Resources exclusively chose n-type mono-bifacial modules in their tenders during this period. Other tenders include PowerChina with over 70% of n-type tenders, China Southern Power Grid with about 60%, and China National Nuclear Corporation (CNNC) with about 25%, highlighting the increasing popularity of n-type products. As for p-type modules, the market is experiencing a shift in demand towards higher-power modules, specifically those exceeding 570W/580W. GCL SI, TW Solar stand out GCL System Integration (GCL SI) led the market with 2 GW secured bids in the first two months of 2024. GCL SI told Solarbe that the company has shipped over 4 GW of modules in the fourth quarter of 2023, making it one of the world’s top 10 module suppliers by shipment volume in the past year. TW Solar closely followed with 1.36 GW of secured tenders, including 1.17 GW from China Resources. Solarbe’s data shows that the company has shipped a total of 32 GW in 2023. JA Solar claimed the third spot with about 970 MW. Other companies that secured bids include EGing PV, DAS Solar, Trina Solar, Canadian Solar, Jinergy, JinkoSolar, Huansheng Solar, etc. N-type prices down by 51% Regarding bidding results for individual projects, the solar module prices have notably declined from Q1 2023 to the first two months of 2024. Specifically: Single-sided 540W+ modules saw the average bid price drop from CNY 1.761/W to CNY 0.96/W, marking a substantial 45% reduction. Bifacial 540W+ modules witnessed a drop from CNY 1.749/W to CNY 0.89/W during the same period, representing a 49% decrease. N-type module prices decreased from CNY 1.849/W to CNY 0.903/W, down by 51%. According to Solarbe, some leading and emerging brands have explicitly shifted away from competing in the p-type market, focusing their efforts on the n-type market. This strategic move has led to intensified competition and substantial price reductions in n-type modules.   For more solar news and solar products needs, please click www.rongstar.com
