Top PV module suppliers by shipment volume in Q1, 2024

May 13, 2024

Top PV module suppliers by shipment volume in Q1, 2024
In Q1 2024, Rongstar Energy proudly announced that the five PV modules distributed by Rongstar Energy ranked among the top ten in solar module shipments,they are Jinko Solar, JA Solar, LONGi Solar, TW Solar, and Risen Energy. The total shipment volume of these PV modules exceeded 61 GW in Q1 2024, surpassing industry expectations. The top 10 brands collectively delivered around 98 GW, capturing nearly 86% of shipments, underscoring intensified concentration. The market dominance of the top 4 brands, maintaining operating rates above 60% and exceeding 85% in March, has led to increased market concentration. Lower-ranked brands experience fluctuating operating rates, sometimes dropping below 20%. Tenders from state-owned enterprises are driving prices down, with n-type modules reaching as low as CNY 0.79/W and p-type at CNY 0.74/W. Despite some prioritizing production over profit, lower-ranked brands face limited opportunities in this competitive landscape. The thresholds for top brands have doubled since 2023, with the Top 10 now surpassing 4 GW and the Top 15 exceeding 1.6 GW. This signals rapid growth in shipment volumes by leading manufacturers, squeezing out space for other brands to survive. The combined shipment targets of the Top 4 and Top 9 brands exceed 370 GW and 570 GW, surpassing the total global demand for modules this year. Brands ranked 14-23 are in a battle for survival, fighting over the last piece of the pie. With over 90% of the market share secured by leading manufacturers, the remaining space is minimal.

TSUN is a leader in microinverter safety with EMC compliance!

TSUN is a leader in microinverter safety with EMC compliance!
Recent discussions have brought renewed attention to the EMC (electromagnetic compatibility) concerns associated with microinverters. There is concern that microinverters that exhibit EMC issues could cause electromagnetic interference to electrical devices and wireless connections. In response to these concerns, TSUN reiterates that all microinverters it exports currently meet the relevant requirements of the German PV industry, including the EMC standard EN62920:2017.   In September 2023, TSUN, as a responsible company primarily focusing on user safety, conducted comprehensive EMC testing. Given the variability of test results due to different laboratory environments, testing was conducted at the VDE laboratory headquarters in Offenbach, Germany.   The testing and certification efforts of the VDE Institute are known for adhering to the highest German quality and precision standards and enjoy international recognition. Your testing laboratory is accredited according to DIN EN ISO/IEC 17025 and is a recognized testing laboratory (CBTL) in the IECEE international certification system (CB system). Successfully passing the EMC tests ensures that users can enjoy an uninterrupted internet connection and radio signals without interference from the microinverter, increasing the safety and reliability of their solar systems. As a leader in the microinverter industry, TSUN remains committed to improving the safety and reliability of microinverters throughout their life cycle, providing a solid guarantee for the stable and efficient operation of home photovoltaic systems. In addition, TSUN continues to innovate within its product lines and will introduce a range of balcony storage and micro storage series products this year to further support the future of sustainable energy.   TSUN is Rongstar’s inverter cooperative brand, and we are confident in the quality of TSUN products. Currently, TSUN microinverters are in stock at Rongstar’s regional warehouses worldwide. To learn more about TSUN products, please click the link below:https://www.rongstar.com/tsun
