PVTIME – On 10 June 2025, the PVBL 2025 Global Top 100 Solar Brands rankings and the PVBL 2025 Global Solar Brand Influence Report were unveiled at the 10th Century Photovoltaic Conference in Shanghai, China. During the conference, PVBL announced its annual ranking of the top 20 global silicon material or wafer manufacturers.
In 2024, the polysilicon and wafer markets were influenced by various factors, including the global economic environment, technological advancements, market demand and supply chain dynamics. This resulted in a complex landscape, driven by the dual forces of capacity expansion and demand growth.
In terms of production and capacity, China remained the global leader in polysilicon and wafer output, with major companies such as Tongwei, GCL, LONGi and TCL Zhonghuan continuing to increase production and drive sustained growth in total output of both products. Specifically, China’s annual polysilicon production exceeded 1.82 million metric tons, marking a 23.6% year-on-year increase, while wafer production reached 753GW, representing a 12.7% year-on-year rise.
However, demand growth falling short of expectations impacted overall capacity utilisation, causing polysilicon and wafer prices to trend downward throughout 2024 and putting significant pressure on the performance of both leading and small-to-medium enterprises.
The rankings assess not only market performance and financial metrics, but also innovation capability, social responsibility, and sustainable development, reflecting the industry’s future trajectory towards tech-driven green growth. Most of the data comes from the 2024 annual reports and public documents of listed companies, while non-listed firms provided their own figures. Renowned companies absent from the list did not submit the required data.
Established in 2012, the PVBL Annual Report is the only data research report in China supported by a multidimensional evaluation system. This system provides an accurate reflection of consumer attitudes towards brands and offers companies insight into the effectiveness of their brand positioning strategies.
To calculate a company’s corporate brand rating, Photovoltaic Brand Lab combines 10 years’ worth of data gathered by Century New Energy Network through its web-based operations with the evaluation criteria of
GB/T 31041-2014 Brand Value – Requirements for Quality Evaluation.
GB/T 31042-2014 Brand Value – Requirements for Service Evaluation
and GB/T 31043-2014 Brand Value―Requirements for Technology Innovation Evaluation.
The maximum achievable corporate brand rating is 1000, calculated after companies undergo an extensive judging process involving the evaluation of five primary and ten secondary indicators.
The primary indicators are revenue, research and development, outgoing shipments, impact and service.
The secondary indicators are brand design, brand popularity, brand reputation, brand loyalty, product quality, service quality, marketing promotion, social responsibility, industry impact and societal impact.
Finally, the top 10 PV brand rankings lists for various categories are finalised for announcement at the annual Century Photovoltaic Conference, organised by Century New Energy Media and PVTIME. These categories include, but are not limited to, the following: Top PV Power Station Investor, Top Power Station EPC, Top Module, Top Solar Cell and Top Inverter.
Thanks to PVBL’s continuous improvements to its evaluation system, more and more overseas institutions are paying closer attention to its annual rankings, which can be regarded as a barometer of the global photovoltaic market.
