China Tightens Rules to End the Solar Panel Price War

The photovoltaic industry is undergoing a major shake-up driven by decisive state intervention. The energy market had been grappling with severe operational distortions and financially unsustainable margins. To curb the price war, the Chinese government has introduced new guidelines for the sector.

Why did China decide to intervene in the solar panel market?

For years, unchecked growth in module manufacturing created a serious excess of production capacity. Domestic companies increasingly sold equipment for less than its true manufacturing cost, seriously undermining the financial balance of the solar ecosystem.

This predatory practice of loss-making sales-known locally as neijuan-eroded operating margins. Faced with an increasingly alarming picture, the government in Beijing called business leaders in and demanded immediate compliance with regulatory requirements.

How does the new unified cost accounting standard work?

To prevent arbitrary manipulation of financial statements, state authorities have rolled out a strict financial accounting standard. Under this approach, all industries must record the real costs of inputs, energy and skilled technical labour involved in production.

With fully harmonised metrics, it becomes strictly forbidden to sell panels at prices below the true cost of production. Enforcement will rely on audited statements to spot irregularities and stop unfair competition across the country’s industrial ecosystem.

Below is a video from the Center for Strategic & International Studies (YouTube) channel on YouTube that explores the points raised in this topic in more depth:

Which government bodies are leading this strict enforcement?

The rules are being implemented with direct involvement from central economic and industrial regulators. The Ministry of Industry and Information Technology works alongside the market regulator to supervise pricing and ensure corporate transparency.

This joint effort includes government bodies such as the MIIT and the SAMR, both focused on stamping out tariff and pricing abuses. Regular meetings with business leaders reinforce the use of administrative sanctions for anyone who breaches the government’s pricing rules.

Pillars of Government Control

Fiscal actions - key guidelines adopted by Chinese regulatory authorities:

1. Mandatory unification of industrial cost accounting criteria;
2. Regularly summoning manufacturers to align on and comply with the rules;
3. Strict inspections coordinated by the MIIT and the SAMR to prevent sales below cost.

What are the main consequences for companies in the sector?

Less efficient firms-or those carrying heavy debt-will come under intense pressure to restructure day-to-day operations. Ending negative-margin sales will drive faster consolidation, pushing out competitors that relied on subsidies or other unsustainable practices in the market.

At the same time, large manufacturers with strong financial capacity are likely to reinforce their competitive position. Price standardisation restores room to invest in technological innovation and in the development of high-efficiency photovoltaic modules with greater durability.

This production reorganisation brings immediate changes to the routine of Chinese factories:

• Immediate adjustment to export pricing strategies;
• A reduction in excess volumes held in solar module stock;
• Renewed focus on profitability and operational sustainability.

What impact is expected on the global photovoltaic energy market?

Price stabilisation in China will feed directly into international pricing for solar equipment. With below-cost pass-throughs halted, global buyers should see a gradual normalisation in the values of panels, delivering greater predictability.

This shift aims to rebalance global supply and support sustainable growth of the clean-energy mix. Beijing’s move signals that the future of the energy transition depends on manufacturers’ financial health and on technological quality.
