After a year and a half of unprecedented low prices, the global solar and energy storage equipment market is approaching a major turning point. According to a new report from Wood Mackenzie, procurement costs for solar and energy storage equipment will increase by approximately 9% starting in the fourth quarter of 2025, marking the end of the bargain pricing period that developers have enjoyed since early 2024.
The driving force behind this dramatic shift? China is changing the rules.
Three Converging Forces Drive Price Increases
Wood Mackenzie’s analysis identifies three critical factors converging to push equipment costs higher, all stemming from significant adjustments in China’s solar industrial chain.
The first major driver is consolidation in the polysilicon sector. Chinese polysilicon capacity expanded fourfold between 2022 and 2024, creating massive oversupply and driving prices down to unsustainable levels. To stabilize the market, new government guidelines have restricted expansion and mandated utilization cuts, reducing production rates to 55-70% among leading producers. This intervention has already triggered a dramatic 48% increase in polysilicon prices in September 2025 alone.
The second factor involves production cuts cascading throughout the solar value chain. Module operating rates among leading manufacturers dropped to 55-60% by mid-2025, while obsolete passive emitter and rear cell (PERC) production lines were phased out, further reducing available capacity. Major Chinese solar manufacturers are systematically retiring outdated PERC technology in favor of more advanced solutions like TOPCon, resulting in a deliberate contraction of manufacturing capacity.
The third and perhaps most impactful factor comes from fiscal policy changes. From Q4 2025, China will cancel the 13% VAT rebate previously applied to exports of solar modules and storage systems. This policy shift carries enormous weight given that China supplies over 80% of global solar modules and 90% of lithium iron phosphate battery packs used in energy storage. The cancellation will directly impact global benchmark pricing, with analysts expecting similar treatment for inverters in the near future.
Global Developers Face Cost Pressures
For solar and storage project developers worldwide, these changes translate into immediate budgetary challenges. In the US market, storage projects sourcing equipment from China will face cost increases, and analysts expect that when the VAT rebate is cancelled for inverters, solar projects in the US will also see higher costs.
“Module manufacturers have already warned international customers to expect approximately 9% price increases in Q4 as a result of the VAT rebate cancellation,” noted Yana Hryshko, senior research analyst and head of Global Solar Supply Chain at Wood Mackenzie. “With no possibility of alternative supply in the short term, developers will have little choice but to absorb these higher costs.”
The implications extend beyond immediate project costs. The research suggests that even developers who secured supply agreements earlier in 2025 will face renegotiation for production scheduled after November 2025, as the new pricing environment takes hold.
From Price War to Market Correction
The past 18 months have been characterized by what industry observers describe as a destructive price war. Solar module prices fell to historic lows of US$0.07-0.09 per watt during 2024 and early 2025, as Chinese manufacturers engaged in price competition despite posting heavy losses. Manufacturers sold solar modules and energy storage systems at rock-bottom prices in desperate attempts to clear excess inventory, even while operating at significant financial losses.
“For the last eighteen months, developers have benefited from solar modules and energy storage systems being sold at rock bottom prices by Chinese manufacturers attempting to shift excess supply,” said Hryshko. “However, this is about to change. The Chinese government has intervened to stabilize the market, and developers globally will have to adjust their procurement expectations accordingly.”
A Structural Shift Toward Sustainability
Wood Mackenzie emphasizes that this pricing adjustment represents more than a temporary market fluctuation. The analysis indicates this represents a structural correction away from destructive price wars toward sustainable margins, rather than a temporary market adjustment.
“This shift will ultimately benefit the industry’s long-term health,” Hryshko explained. “For manufacturers, it represents a welcome opportunity to reinvest and innovate. For developers globally, it means adjusting procurement expectations. And for policymakers, it’s a timely reminder of the risks inherent in concentrated supply chains.”
Industry analysts argue that while manufacturers have suffered through an extended period of unsustainable pricing, the market correction will enable them to return to profitability. This financial breathing room should facilitate renewed investment in research and development, driving technological innovation and product improvements rather than a singular focus on cost-cutting and volume production.
Industry Enters New Phase
The price adjustment signals the global solar industry’s entry into a new development phase. After experiencing the chaos of overcapacity-driven price warfare, the sector is returning to rationality. Manufacturers will have greater capacity for technological innovation and product upgrades instead of competing solely on price.
For project developers, while rising costs create certain pressures, a more stable and healthy supply chain environment, along with more predictable pricing systems, will benefit the industry’s sustainable development in the long run. The extreme volatility of the past 18 months, while advantageous for procurement budgets, created planning uncertainties and supply chain risks that proved problematic for long-term project development.
Despite equipment price increases, global demand for clean energy remains robust. Government carbon neutrality commitments and energy transition policies worldwide continue providing a solid foundation for solar and energy storage industry growth. Analysts predict that after a period of short-term adjustment, the market will find equilibrium at new price levels and maintain growth momentum.
Supply Chain Concentration Risks Highlighted
This price adjustment also underscores the risks of highly concentrated global solar supply chains. As Chinese policies adjust, the global market immediately experiences significant impacts, prompting countries to reconsider energy supply chain diversification and localization. Some nations and regions are increasing investments in domestic solar manufacturing capabilities to reduce dependence on single supply sources.
The United States, European Union, and other markets have already initiated efforts to build domestic solar manufacturing capacity, partly driven by energy security concerns and partly motivated by industrial policy objectives. The Inflation Reduction Act in the United States, for example, includes substantial incentives for domestic solar manufacturing, though the recent passage of the One Big Beautiful Bill Act has introduced new uncertainties regarding long-term support.
Looking Ahead
As the industry adapts to this new pricing environment, several key questions remain. How quickly will alternative supply chains develop outside of China? Will the price stabilization encourage new market entrants? And how will project economics adjust to the higher equipment costs?
What seems certain is that the era of extraordinarily cheap solar and storage equipment has concluded. The industry now faces a period of recalibration, with developers, manufacturers, and policymakers all adjusting to a market structure that prioritizes sustainability over volume.
For the renewable energy transition, this may ultimately prove beneficial. While higher upfront costs present challenges, a healthier manufacturing sector with sustainable margins can support the long-term innovation and capacity expansion necessary to meet global decarbonization goals. The key will be ensuring that rising equipment costs don’t significantly slow deployment rates at a critical moment in the energy transition.
In conclusion, while solar and storage equipment price increases will create short-term cost pressures, they contribute to establishing a healthier, more sustainable industrial ecosystem over the long term. This market adjustment triggered by Chinese policy is reshaping the global solar industry landscape, driving the sector’s transition from quantity-focused growth to quality-oriented improvement.
