Top 5 inverter companies dominate 85% of Q1 2024 bids
China's solar industry is booming in early 2024, with new installations soaring to 36.72 GW in just January and February, marking an 80% increase from the previous year. State-owned enterprises are actively pursuing solar equipment tenders to capitalize on this growth. In the first quarter of 2024, over 62.44 GW of solar inverter procurement bids were announced, up by 32% compared to the same period in 2023. String inverters dominated the market, accounting for 80% of total bids, with large-capacity inverters with over 300kW making up 84% of this category. The top five companies securing bids—Sungrow, Huawei, Sineng Electric, Zhuzhou Converter, and TBEA—accounted for nearly 85% of the total procurement volume, maintaining their dominance in the market. The top performer in the industry, Sungrow successfully secured bids for 5 GW of inverters. Rongstar can confidently state that choosing Sungrow as our solar inverters supplier would be an excellent decision.  More inverters information at:https://www.rongstar.com/soar-inverters-ess

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

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
