China’s solar equipment manufacturers are learning they need to exercise restraint to survive.

More than 30 of the top companies signed up to a programme of self-discipline at the China Photovoltaic Industry Association’s annual meeting last week, in an agreement fashioned after the way the Organisation of Petroleum Exporting Countries manages its oil supply.

The firms will receive quotas for how much they can produce next year, based on their existing market share and capacity as well as expected demand, according to local media.

The CPIA declined to comment on the agreement.

The accord comes as China’s solar industry contends with overcapacity, heightened geopolitical tensions and slowing demand. Companies are focused on riding out the storm in the belief that it could be at least another year or more before profits begin to recover.

The agreement represents a sharp turnaround from years of stiff competition that have brought the industry to its knees, while at the same time slashing prices and raising quality to the point that solar power is the cheapest and fastest growing form of energy.

It’s too early to tell whether quotas can succeed in such a fragmented and competitive industry. But what’s clear from comments made by solar executives at two high-profile events last week — the BloombergNEF Summit in Shanghai and the China Photovoltaic Industry Association’s gathering in Yibin, Sichuan — is the desperation behind the move.

‘Surviving’

“The keyword for next year is surviving,” Xing Guoqiang, chief technology officer at Tongwei, said at the Shanghai event. “2025 will be very important for many companies to survive this cycle.”

The root of the sector’s woes was a factory build-out that started in 2021, which led to massive overcapacity, especially in China, where more than 80% of global manufacturing takes place. There’s currently enough capacity to build more than 1 100GW of panels a year. That’s not only nearly double what the world is expected to have installed in 2024, it’s more than it’s going to need as far out as 2035, according to BloombergNEF forecasts.

Solar isn’t alone when it comes to battling overcapacity in China, where breakneck growth in recent decades led to excessive investment that’s now running ahead of a slowing economy. From copper smelters to steelmakers and oil refiners, industries throughout the country are dealing with the problem of everyone agreeing that plants need to be shut, and no one willing to be the first to take the plunge.

The solar industry’s saving grace was soaring demand for its products, but that’s fading. Global installations surged 76% in 2023 and are expected to increase by another 34% this year, but growth will slow to just 8% in 2025, according to BloombergNEF. Trade tensions are also a factor, pushing Chinese companies to set up plants in countries like the US, India and Indonesia to try and avoid rising tariffs.

Excess capacity has forced companies to slash their prices, in many cases below production costs. Longi Green Energy Technology, until recently the biggest solar manufacturer, is expected to post a net loss of nearly US$1-billion this year, after making a profit of over $1.7-billion in 2023. Most executives said they didn’t expect the situation to improve until the second half of 2025, although some were even more pessimistic.

“Considering the current capacity level, it might take at least three years for the wafer and module sectors to bottom out,” Zhang Longgen, chairman of United Solar Polysilicon, said in Shanghai.

The strains were apparent in Yibin, a city in southwest China known for its spicy cuisine and fiery baijiu liquor. The CPIA hosted a meeting there with Chinese media in which it scolded reporters for focusing on negative news and implored them to help promote the sector.

Solar companies are used to more positive coverage. In addition to producing the clean energy that’s vital to winning the fight against climate change, they’re also known for their technical prowess, which has helped cut costs by more than 90% over the past decade. That’s led to truly remarkable growth. In 2014 there were less than 200GW of solar panels installed in the world. By the end of this year, there’ll be more than 2 200GW, according to BloombergNEF.

Such rapid development has created multibillion-dollar manufacturing giants, but it’s also left a trail of corporate failures in its wake. Suntech Power Holdings and Yingli Green Energy Holding were the world’s biggest panel makers in the early 2010s. Neither has survived.

So, the lesson in Yibin was how to avoid a repeat. Executives spoke about the need to show restraint and avoid vicious competition, citing Opec as a model for managing prices. At the same time, some were ambivalent about whether companies will adhere to the new rules.

Staunch the bleeding

“If you make a promise, how do you actually follow through?” asked Lu Chuan, chairman of Chint New Energy Technology. “How do you reach consensus and take punitive measures in the absence of self-discipline? I think these issues will continue to be discussed in the future.”

Still, the agreement should at the very least help staunch the bleeding in the sector and could help boost prices. Now, it’s just a question of how well the companies carry out the plan. — (c) 2024 Bloomberg LP
