Beijing’s New Solar Power Rules to Spark ‘Major Reshuffle’

China's solar industry is undergoing significant changes due to new regulatory measures designed to curb rapid manufacturing capacity expansion while enhancing product quality. Key changes include mandates for reduced debt in new projects and higher product quality standards. This regulatory shift is anticipated to trigger market consolidation, pushing out less efficient firms and favoring top manufacturers, with the process continuing until mid-2025 [para. 1][para. 2][para. 3].

The excessive manufacturing capacity has intensified a price war, compelling many companies to sell products at a loss. The new rules, updated by China’s Ministry of Industry and Information Technology on November 20, aim to stabilize the overheated industry by addressing these imbalances [para. 3][para. 4][para. 5]. During a June conference in Shanghai, solar industry executives shared concerns over chaotic expansion and financial challenges, which were reiterated in a recent Chengdu conference [para. 6][para. 7].

Financial difficulties are evident, as 39 out of 121 listed Chinese solar firms reported losses in the first three quarters of the year. In the face of a drastic 60-80% price drop since the market highs in 2023, these financial strains are reportedly worse than in previous downturns [para. 9][para. 10][para. 11].

A dominant factor driving overcapacity is smaller companies with "super-low prices," forcing other players into similar pricing strategies. Despite being categorized as small, many have sizable production capabilities, like those with 30 GW of capacity compared to top-tier manufacturers with around 100 GW [para. 12][para. 13][para. 14].

An important rule change involves increasing the minimum capital ratio for solar manufacturing projects from 20% to 30%, applicable across all production types. This increase, which previously applied only to polysilicon production, will particularly impact smaller manufacturers with limited resources [para. 15][para. 16][para. 17]. This adjustment reflects the government’s acknowledgment of the overcapacity issue throughout the industry [para. 18].

The imposition of a minimum efficiency standard for manufacturing projects seeking capacity expansion is also crucial. The new rules specify that N-type cells must reach at least a 26% average conversion efficiency, up from 23% in 2021. This requirement aims to phase out low-quality, inefficient manufacturers [para. 19][para. 20][para. 22]. The average solar cell efficiency increases by approximately 0.1% each quarter, but reaching the 26% target will require notable performance improvements from many manufacturers [para. 22].

The Ministry has committed to collaborating with research bodies and trade institutions to enforce the new regulations and will regularly publish lists of compliant companies. If enforced rigorously, these measures could significantly reshape the industry by eliminating smaller, underperforming firms and leaving only top-tier companies [para. 24][para. 27].
