Solar module pricing tracker Q2 2026: where solar panel costs are going

In 50 words: Tier 1 TOPCon bifacial modules now price at $0.094/W for India delivery, down 7% quarter-on-quarter. The supply chain has stabilised — polysilicon at $5.80/kg, cells at $0.029/W. Developers locking Q4 2026 commissioning contracts should target $0.090/W or below for serious bid competitiveness.

1. The headline number and why it matters

In May 2026, Tier 1 TOPCon bifacial solar modules price at $0.094/W FOB China for India delivery — down 7% quarter-on-quarter. For a 100 MW utility-scale project, the difference between $0.094/W and $0.090/W is $400,000 — meaningful margin in competitive tender bidding.

Module pricing is the single largest cost component of a solar project (35-45% of utility-scale capex, 40-50% of residential). Tracking it precisely is essential for procurement timing, bid competitiveness, and project economics.

2. The full price stack — polysilicon to module

The solar module supply chain has four sequential stages, each adding cost:

| Component | Price (May 2026) | Note | |---|---|---| | Polysilicon | $5.80/kg | Stable in narrow $5.50–6.10 range for 3 months | | Wafer (M10/G12) | $0.034/W | Slight compression on wafer thinning | | Cell (TOPCon) | $0.029/W | New cell capacity coming online | | Module (bifacial TOPCon) | $0.094/W | 7% drop QoQ |

Understanding the breakdown matters because price movements at different stages signal different things. Polysilicon moves on supply discipline + raw material costs; wafer on thinning technology; cell on capacity overhang; module on demand + competition.

A useful rule: module price is roughly 3.2x the cell price. When cells are $0.029/W, modules around $0.092-0.094/W is the expected range. Significant deviations indicate either premium products (higher) or distressed inventory clearance (lower).

3. What drives module pricing (the four levers)

Lever 1: Cell capacity overhang

New TOPCon cell lines commissioned in late 2025 reached full ramp by Q2 2026, putting downward pressure on cell pricing. Global cell manufacturing capacity now exceeds demand by roughly 40-50% — a structural oversupply that keeps prices compressed. This oversupply is the dominant downward force on module prices in 2026.

Lever 2: Wafer thinning

Standard M10 wafer thickness has dropped to 130μm at Tier 1 producers (from 150μm in 2023), saving roughly $0.002/W in silicon cost. Each thinning step reduces polysilicon consumption per watt — a continuous incremental cost reduction.

Lever 3: Polysilicon discipline

Chinese polysilicon producers held production cuts through Q1 2026, keeping polysilicon in a tight $5.50-6.10/kg range and preventing the deeper price collapse some analysts forecast. Polysilicon producers learned from the 2023-2024 price crash (which destroyed margins) and now coordinate production to stabilise pricing.

Lever 4: Demand cyclicality

Module demand peaks around major installation seasons and conference cycles (SNEC in June drives Q2-Q3 contracting). Prices often firm slightly during peak demand, soften during off-season.

4. Regional price variations — China, India, US, EU

The same Tier 1 module commands very different prices depending on destination:

| Market | Tier 1 TOPCon bifacial price | Premium vs China FOB | Why | |---|---|---|---| | China domestic | $0.085/W | baseline | No freight, no duty | | India (delivered) | $0.094/W | +11% | Freight + duty + ALMM dynamics | | MENA (delivered) | $0.090/W | +6% | Freight, lower duty | | EU (delivered) | $0.110/W | +29% | CBAM, freight, anti-dumping considerations | | US (delivered) | $0.280/W+ | +230% | Tariffs, AD/CVD, domestic content premium |

The US price stands out — tariffs and trade measures roughly triple the effective module cost. This is why US utility-scale solar economics differ so dramatically from the rest of the world, and why IRA domestic content incentives are structured the way they are.

5. TOPCon vs HJT vs PERC pricing by technology

Within the module market, technology choice affects price:

| Technology | Price (India delivery) | Premium vs TOPCon | Efficiency | |---|---|---|---| | PERC (legacy) | $0.082/W | -13% | 21-22% module | | TOPCon bifacial | $0.094/W | baseline | 22-23% module | | HJT | $0.108/W | +15% | 23-24% module | | Back-contact (IBC/ABC) | $0.135/W | +44% | 23-24%+ module |

TOPCon is the value-optimal choice for most 2026 projects — best balance of efficiency and price. PERC is cheaper but sunsetting (avoid for new 25-year projects). HJT commands a premium justified only where its efficiency edge and lower degradation pay back. Back-contact is premium-niche.

6. The 2022-2026 price decline in context

Solar module prices have fallen dramatically:

• 2022: $0.26/W (post-COVID supply crunch + polysilicon spike)
• 2023: $0.18/W
• 2024: $0.12/W
• 2025: $0.10/W
• Q2 2026: $0.094/W

That's a 64% decline in four years. The decline reflects: polysilicon capacity normalising after the 2022 shortage, cell + module manufacturing massively over-built (creating oversupply), and continuous technology cost reduction (wafer thinning, efficiency gains).

The pace of decline is now slowing. The dramatic drops are largely behind us. Expect $0.085-0.095/W to be the rough floor through 2027 absent major demand shifts — module manufacturers are operating near or below cash cost and cannot sustain much further decline.

7. Where prices go through 2027

Realistic forecast:

• Q3 2026: $0.090-0.094/W (firming slightly with SNEC-cycle demand)
• Q4 2026: $0.088-0.092/W
• 2027: $0.085-0.095/W range, relatively flat

Two factors could push prices DOWN further: continued cell oversupply, weaker-than-expected demand. Two factors could push UP: polysilicon supply discipline tightening, demand surge from grid + data center electrification.

Net: don't expect another dramatic decline. The "wait for cheaper modules" strategy that worked 2022-2024 no longer applies. Module prices are near structural floor.

8. Procurement playbook for developers

For developers timing module procurement:

Indian utility-scale (Q4 2026 commissioning, Q3 delivery)

• Target price: $0.090-0.093/W for Tier 1 ALMM-eligible bifacial TOPCon
• Walk-away premium: anything above $0.098/W deserves scrutiny — better deals are available
• Domestic content premium: budget ₹0.30-0.50/W (≈$0.004-0.006/W) extra for ALMM-only supply depending on cell sourcing

Timing strategy

• Module prices are near floor — don't speculate on further declines
• Lock pricing 2-3 quarters before commissioning to avoid supply crunches
• For 2027 commissioning, contract in H2 2026
• Build inflation/escalation clauses for delivery beyond 6 months

Supplier diversification

• Don't single-source — split across 2-3 Tier 1 suppliers
• Verify ALMM listing status at contracting (lists update)
• Verify Tier 1 bankability (warranties only matter if manufacturer survives 25 years)

Quality vs price

• The $0.082/W PERC vs $0.094/W TOPCon gap is real, but TOPCon's lower degradation (0.42%/year vs 0.48%) and higher efficiency justify the premium over a 25-year project
• Don't chase the cheapest module — chase lowest levelized cost of energy

9. ALMM and domestic content premium in India

For Indian government-supported projects (SECI, state tenders), modules must be ALMM-listed. This creates a domestic content premium:

• Imported Chinese modules: $0.094/W (but not ALMM-eligible for government tenders)
• Indian Tier 1 ALMM modules: $0.098-0.104/W (ALMM-eligible)
• Premium for ALMM eligibility: roughly $0.004-0.010/W

The premium reflects India's still-developing cell manufacturing (most Indian modules use imported cells, adding cost). As India's domestic cell capacity scales (ALMM cell list expected Q3 2026), this premium should compress toward $0.002-0.004/W by 2027-2028.

For non-government Indian projects (open access, C&I, merchant), imported modules can be used, accessing the lower $0.094/W pricing.

10. What to watch next

Two factors could move module pricing meaningfully through Q3-Q4 2026:

1. EU CBAM polysilicon scope expansion. With CBAM extending to polysilicon and wafers (2026 amendments), lower-emission Chinese polysilicon may get redirected to EU buyers willing to pay the CBAM-compliant premium — potentially raising the polysilicon available for India-delivery modules and nudging Indian module prices marginally higher.

2. ALMM List expansion (mid-2026). Adding 15+ new module producers to the ALMM list increases domestic competition, which should pull the Indian domestic content premium lower — good news for Indian developers.

For the most current pricing, track InfoLink and BNEF weekly module price indices. We update this tracker quarterly. The bottom line for 2026: module prices are near structural floor, the era of dramatic declines is over, and procurement strategy should focus on timing certainty and supplier quality rather than waiting for further price drops.
