Top PV module suppliers by shipment in H1 2024

July 29, 2024

Top PV module suppliers by shipment in H1 2024
JinkoSolar, Trina Solar, JA Solar and Longi Solar, have achieved a total shipment of over 140GW in the first half of 2024, 52% of the market share, while the total volume for top 10 is above 225GW, taking 82% of the market, which is lower than that of the first quarter, according to the latest data provided by Solarbe. Meanwhile, the annual shipment target of Top 10 manufacturers has exceeded the total market demand, leaving less space for later companies, reflecting in their less shipment in the second quarter. JinkoSolar once again secured the ‘top seller’ title by virtue of its strong brand advantage, with 44-46GW of modules shipped in H1. Meanwhile, the competition is getting more fierce between JA Solar and Trina Solar with evenly matched shipment during the period, whilst JA Solar is more favored for prices and Trina Solar takes more initiative relying on their own channels, said some distributors. Tongwei Solar and Astronergy recently participated in the bidding with higher enthusiasm. Both companies have proposed a full-year shipment target of more than 50GW, a significant increase from 2023, and overseas markets should be included if they aim to achieve the targets. Canadian Solar and GCL System Integration are among the few module companies that still achieve profit in H1 due to their outstanding capabilities in selecting orders and cost control. DAS Solar revealed a stronger spirit and positive attitude in bidding, further enhanced their links with central and state-owned enterprises. Risen Energy, one of the few manufacturers in the market that can supply both TOPCon and heterojunction modules in bulk at the same time, also set a firm foothold among the top 10 suppliers. Behind the ranking The share of rectangular cell modules has increased, with 2382*1134mm becoming the recognized standard size. In terms of parameters, many bidding companies increase the power requirements to 600W+, and do not limit the module length and cell size, making the 182*182mm square cell and 2278*1134mm module outdated, and 2382*1134mm will prevail on more power stations. Overseas markets have become the biggest share of profits, and companies have strong demand for going abroad. In this survey, at least 10 companies have reached or exceeded 50% of their overseas market sales (in terms of shipments), of which six are in the top 10 list. The annual DC side installed capacity is expected to be 450GW-510GW, an increase of about 15% over 2023, reaching a new high. The increase is more prominent in overseas markets.
