Why Solar Panel Prices Are Likely to Rise: 3 Forces Reshaping the PV Supply Chain

For more than two years, the global solar industry has benefited from aggressive competition, oversupply and historically low pricing across polysilicon, wafers, cells and modules.

But the market is beginning to change.

At PV.market, we believe buyers, EPCs, distributors and project developers should pay close attention to what is happening upstream because several major cost and policy drivers are now moving in the same direction.

The important question may no longer be: “How much lower can solar module prices go?”

It may increasingly become: “How long will today’s module prices remain available?”

Three developments are particularly important.

1. China is drawing a line under below-cost competition

China is drawing a line under below-cost competition

On August 6, eight of China’s largest polysilicon producers — including Tongwei, GCL Technology, Daqo New Energy, Xinte Energy, Asia Silicon, East Hope, Qinghai Lihao and Xinjiang Goens Energy Technology — signed an industry initiative committing not to sell products below their calculated full cost.

Together, these manufacturers represent more than 90% of China’s effective polysilicon capacity.

This followed regulatory action in China aimed at reducing destructive “involution-style” price competition and encouraging manufacturers to move away from aggressive below-cost selling.

The market reaction was immediate.

The most-traded polysilicon futures contract rose from approximately CNY 32,560/ton before the July 31 regulatory meeting to CNY 37,040/ton on August 7 — an increase of roughly 13.8%.

This matters because polysilicon sits at the beginning of the crystalline-silicon PV value chain:

Polysilicon → Wafer → Cell → Module

If manufacturers successfully establish a stronger cost floor upstream, some of that pressure will ultimately move downstream.

China still has significant polysilicon inventory and oversupply, so this does not mean prices must rise continuously. But the era in which manufacturers repeatedly sold below sustainable production cost may be becoming harder to maintain.

2. U.S. Section 232 is creating a powerful solar-cell demand window

U.S. Section 232 is creating a powerful solar-cell demand window

The second major factor is coming from the United States.

On August 6, 2026, the U.S. government announced new Section 232 measures covering polysilicon and downstream solar products.

From December 4, 2026, the framework introduces minimum import prices of:

• Polysilicon: $21/kg
• Ingots & wafers: $100/kg
• Solar cells: $0.22/W
• Solar modules: $0.38/W

The measures also include an additional 15% ad valorem tariff on covered downstream polysilicon derivatives, subject to the provisions of the proclamation.

This is particularly significant for the solar-cell market.

The United States has built substantial module-assembly capacity, but domestic cell manufacturing remains far smaller. Recent analysis cited U.S. operating cell capacity at only around 3.2 GW, with more than 90% of cells used by domestic module manufacturing still coming from imports.

That creates strong incentives for supply-chain participants to secure cells ahead of the December implementation date.

And we are already seeing the impact.

According to Shanghai Metals Market analysis, mainstream Chinese TOPCon solar-cell prices had increased by more than 20% from late-July/early-August lows by August 18, with some specifications approaching a 30% rebound.

SMM specifically identified expectations of front-loaded U.S.-related procurement following Section 232 as an important factor accelerating the rally.

This creates a global consequence.

If U.S.-oriented buyers are willing to pay stronger prices for cells, cell manufacturers and traders naturally have less incentive to release the same production at significantly lower prices to ordinary module manufacturers.

That creates competition for available cell supply — and increases the production cost of the module.

3. Silver is becoming a major production-cost problem

Silver is becoming a major production-cost problem

One of the most overlooked components of a solar cell is silver.

Silver paste is used for electrical contacts in crystalline-silicon solar cells, particularly in high-efficiency technologies such as TOPCon.

And silver is no longer a minor cost item.

Heraeus Precious Metals estimated earlier this year that, during periods of extreme silver pricing, silver paste could represent as much as 30% of total solar-cell manufacturing cost.

IRENA also noted that rising silver prices contributed to the increase in average solar-cell prices during Q1 2026.

The pressure has not disappeared.

COMEX silver settled at approximately $68.03/oz on August 20, following a 6.39% increase over just two trading days.

So while the percentage movement depends on the timeframe selected, the broader conclusion is clear:

Silver remains structurally expensive relative to historical PV manufacturing economics.

For cell manufacturers already operating on extremely thin margins, higher silver-paste costs cannot indefinitely be absorbed internally.

Eventually, that cost must either be reduced through technological changes and silver-thrifting — or transferred downstream.

The important signal: cell costs are moving before module prices

This is where buyers should pay particular attention.

As of August 19, SMM was still assessing FOB China mainstream TOPCon module pricing around $0.105–$0.107/W, depending on format.

In other words: The full increase in upstream cell and material costs has not yet been completely transmitted into module selling prices.

That creates a potential timing gap.

What could happen next?

If the following continue simultaneously:

1. Polysilicon manufacturers maintain cost-based pricing discipline

2. Wafer and cell prices continue recovering

3. U.S.-related cell procurement remains strong before December

4. Silver and silver-paste costs remain elevated

5. Module manufacturers refuse to continue absorbing higher production costs

then upward pressure on global module quotations becomes increasingly difficult to avoid.

This does not mean every module price in every market will rise immediately.

Inventory, destination, technology, manufacturer strategy, shipping position and local demand will continue to create price differences.

But the risk/reward calculation for waiting indefinitely for lower prices has changed.

What PV buyers should consider

What PV buyers should consider

For EPCs, distributors and project developers with confirmed Q4 2026 or early-2027 requirements, this may be the right time to:

• Request updated quotations rather than relying on prices received several weeks ago.
• Compare ready-stock opportunities with future-production offers.
• Confirm quotation validity periods.
• Evaluate whether part of the required volume should be secured earlier.
• Monitor cell and polysilicon pricing — not only finished-module quotations.

At PV.market, we continue to monitor global solar supply, ready stock, manufacturer offers and RFQs https://pv.market/request-for-quote to help buyers and sellers respond to changing market conditions.

The next phase of the solar market may not be defined by another race toward the lowest possible module price.

It may instead be defined by cost recovery, disciplined manufacturing and competition for strategic supply.

And that could make today's available solar-module prices more valuable than many buyers currently realize.
