What Happened on February 28, 2026
The global solar supply chain changed in a single day. On February 28, 2026, the United States and Israel launched coordinated military strikes against Iran — Operation Epic Fury — targeting nuclear facilities, military infrastructure, and senior leadership. Iranian Supreme Leader Ali Khamenei was killed in the opening strikes. Iran retaliated immediately with waves of ballistic missiles and drones against Israel and US military bases across the Gulf region.
Iran’s response included a step that sent immediate shockwaves through global trade: it effectively closed the Strait of Hormuz. The IRGC officially confirmed the closure on March 2, 2026, and threatened to strike any vessel attempting transit. Major container shipping carriers — Maersk, Hapag-Lloyd, MSC, and CMA CGM — suspended all Strait of Hormuz transits within days.
Why the Strait of Hormuz Matters to Solar Importers
The Strait of Hormuz connects the Persian Gulf to the Gulf of Oman and the world’s open shipping lanes beyond. According to Kpler’s 2025 data, approximately 13 million barrels of crude oil per day — roughly 31% of all seaborne crude flows — normally transit the Strait. The US Energy Information Administration (EIA) estimates that when refined petroleum products are included, the Strait carries volumes equivalent to approximately 20% of total global petroleum liquids consumption annually. It is also a critical gateway for a major transshipment hub at Jebel Ali in the UAE, which handles a significant share of Asia-to-Europe and Asia-to-Middle East container trade.
For solar importers sourcing from China’s Zhejiang, Jiangsu, or Guangdong manufacturing hubs, the direct transit route does not pass through Hormuz. But the closure affects you in three ways: it drives up bunker fuel prices globally, removes vessel capacity from the wider market as ships reroute, and forces cascading surcharges across all major trade lanes — including the transpacific.
Key Events: February 28 – March 8, 2026
Feb 28
US-Israel strikes begin. Coordinated airstrikes on Iranian military, nuclear, and government targets. Supreme Leader Khamenei killed. Iran launches retaliatory missile and drone strikes on Israel and Gulf states hosting US forces.
Feb 28 – Mar 1
Hormuz traffic collapses. Outbound traffic initially heavy, then drops to near zero. Maersk, Hapag-Lloyd, MSC, CMA CGM all issue suspension notices. At least three tankers struck near the Strait.
Mar 2
IRGC officially declares the Strait closed. Protection and indemnity insurance suspended for Gulf transits. Chinese methanol futures hit the daily trading limit. Xeneta records 147 container ships sheltering in the Persian Gulf.
Mar 5
First full freight rate data. Xeneta records spot rate increases of 5–13% across major Asia-origin trade lanes in a single week. Vespucci Maritime CEO estimates ~2 million TEU of containerised cargo disrupted. Iran has fired over 500 ballistic missiles and ~2,000 drones since February 28.
Mar 8
Conflict continues. No ceasefire. Diplomatic channels remain open but no resolution in sight. Insurance premiums for Gulf transits elevated. Alternative port congestion intensifying. April 1 VAT deadline approaching.
The Shipping Crisis: What the Strait of Hormuz Closure Costs You
Freight data makes the impact concrete. Xeneta — the industry’s leading EU BMR-compliant ocean freight benchmarking platform — recorded these spot rate changes in the single week ending March 5, 2026:
| Route (Far East Origin) | Feb 26, 2026 | Mar 5, 2026 | 1-Week Change |
|---|---|---|---|
| → US West Coast | $1,883 / FEU | $2,123 / FEU | +13% |
| → US East Coast | $2,659 / FEU | $2,870 / FEU | +8% |
| → Mediterranean | $3,335 / FEU | $3,570 / FEU | +7% |
| → North Europe | $2,224 / FEU | $2,338 / FEU | +5% |
Source: Xeneta spot rate data, week of March 5, 2026. FEU = Forty-foot Equivalent Unit (standard 40-foot container).
These are first-week figures. To understand what they could become, consider the scale of the Red Sea crisis of 2023–24 — a comparable but ultimately less severe disruption. That crisis drove Far East freight rates up 100–400% from their pre-crisis baseline at the peak, before rates gradually normalised back toward pre-crisis levels by early 2026. On the transpacific, Xeneta recorded spot rates climbing from approximately $1,643/FEU in December 2023 to $8,023/FEU at the July 2024 peak — an increase of nearly 400%. Asia–Europe routes roughly tripled during the same period. If the Hormuz closure persists into Q2, sustained rate increases of comparable magnitude are a realistic scenario — though the timeline and ceiling remain uncertain at this stage.
What Rerouting Actually Costs
With the Strait closed and the Red Sea also disrupted (Houthi forces resumed attacks on commercial shipping on February 28), vessels have one main alternative: the Cape of Good Hope route around southern Africa. This adds:
- 10–14 extra transit days on Asia-to-Europe routes, and additional days on Asia-to-East Coast US routes that normally transit Suez
- Significantly higher bunker fuel costs — every additional sea day burns more fuel at current elevated oil prices
- Higher war-risk insurance premiums, which had already risen from 0.125% to 0.2–0.4% of vessel value per transit before the strikes began
- Port congestion at alternative hubs — Xeneta’s Peter Sand has noted that ports along alternate routes were not designed to absorb sudden volume surges
There is also a compounding problem that does not show up in rate tables: cascade delays. Vessels trapped in the Gulf cannot continue service rotations. A ship immobilised in the Persian Gulf creates a gap across four or five subsequent port calls. According to Vespucci Maritime CEO Lars Jensen, approximately 2 million TEU of containerised cargo was caught up in the Hormuz crisis by March 5 — a figure that measures not just what is trapped but the full downstream disruption across global shipping loops.
Three Cost Forces Converging at Once
Freight is visible and immediate. But it arrived on top of two other pressures that were already in motion. Understanding all three — and how they interact — is essential for procurement planning right now.
Force 1: The Middle East Conflict and Freight Shock
Covered in detail above. The key point for procurement teams is that this is not a contained local event. The Hormuz closure disrupts global energy markets, elevates bunker costs fleet-wide, and removes effective container capacity from all major trade lanes — not just routes that directly transit the Strait.
Brent crude oil has surged following the strikes. European gas reference prices jumped sharply in the days after February 28. Both feed directly into vessel operating costs, and carriers pass those costs to shippers through bunker adjustment factors and general rate increases.
Force 2: China’s VAT Export Rebate Elimination (April 1, 2026)
This one was announced on January 9, 2026, in a joint notice from China’s Ministry of Finance and the State Taxation Administration. It is confirmed government policy. It is not subject to reversal. From April 1, 2026, China will completely eliminate the VAT export rebate for solar PV products.
The rebate history matters for context: China originally offered a 13% VAT rebate on PV exports as part of its industrial policy. That was reduced to 9% in late 2024. On April 1, 2026, it goes to zero. What this means in practice is that manufacturers who previously recovered a portion of their domestic VAT through export rebates now bear that cost in full — and most will pass it to international buyers.
The direct cost impact is approximately 9%, according to ARC Advisory Group and OPIS analyst assessments. When combined with the raw material pressures described below, total module price increases of 10–15% from pre-April levels are the realistic range that industry analysts project.
Force 3: Raw Material Costs at Multi-Year Highs
Both silver and methanol — critical inputs to solar manufacturing — are under pressure from separate but compounding factors. Full details are in Section 6 below. The short version: silver reached a record high of $83.62 per ounce on December 28, 2025, and remains historically elevated in the $82–$95/oz range as of publication — with conflict-driven safe-haven demand now adding a new floor; and Iran’s conflict-driven supply disruptions are putting upward pressure on China’s methanol imports, which feed into PV glass production.
What You’re Paying Now: Verified Price Data
Module prices have been rising since early 2025, driven first by silver costs and the VAT announcement, then accelerated by the conflict. The following data is drawn from InfoLink, OPIS, and PV Tech’s PV Price Watch series — the most authoritative publicly available sources for Chinese FOB module pricing.
Dec 2024 (Baseline)
$0.086–0.092
per watt, FOB China
January 2026
$0.096–0.10
+10–15% vs baseline
February 2026
$0.11–0.125
+27–36% vs baseline
March 2026
$0.12–0.125
~+30–40% vs baseline
April 2026 (Projected)

+41–55% vs baseline
Source: InfoLink Consulting, OPIS FOB China pricing service, PV Tech PV Price Watch. FOB China prices only — does not include freight, insurance, duties, or brokerage. N-type TOPCon modules.
In Chinese domestic market terms, N-type TOPCon modules were trading at RMB 0.70–0.75 per watt in early 2026, equating to roughly $0.097–0.104 per watt at prevailing exchange rates. Premium back-contact (BC) modules commanded slightly higher quotes. These domestic prices feed directly into export pricing as the rebate structure changes.
“OPIS FOB China TOPCon spot module prices have risen more than 30% since the start of the year, and the forward curve shows modules offered for delivery later in 2026 are priced higher than prompt levels.”— Isabella Tang, OPIS FOB China Analyst
The forward curve signal is important. When manufacturers price future delivery higher than current spot, they are already building in the April 1 VAT change. They are not expecting prices to come down after the deadline. They are pricing the floor higher — for the rest of the year.
Container-Level Impact: What One Shipment Costs Now
Let us translate this into procurement reality. A standard 40-foot container of mid-tier TOPCon panels holds approximately 0.5 MW (500 kW).
| Period | Module Cost (0.5 MW) | Freight (Far East → US West) | Combined Estimate | vs Dec 2024 |
|---|---|---|---|---|
| December 2024 | ~$43,000–46,000 | $1,883 | ~$45,000 | Baseline |
| March 2026 (current) | ~$60,000–62,500 | $2,123 | ~$62,500–64,600 | +39–44% |
| April 2026 (projected) | ~$65,000–67,500 | $2,400–2,700* | ~$67,500–70,200 | +50–56% |
*Freight projection based on sustained conflict scenario. Source: module pricing from InfoLink/OPIS; freight from Xeneta. Indicative only — actual costs vary by product spec, supplier, and market conditions. Does not include duties, insurance, brokerage, or port fees.
At current rates, one container per month costs roughly $17,500–$19,600 more than it did in late 2024. Over twelve months, that is over $210,000 in additional costs — before the April 1 increase and before any further freight escalation. For operations importing five to ten containers monthly, the annual exposure runs to seven figures.
The April 1 Deadline That Cannot Be Ignored
The Middle East conflict is unpredictable. It may escalate; it may de-escalate. What is not unpredictable is April 1, 2026. That date is fixed, confirmed, and will not move.
What the Policy Actually Does
For over a decade, China’s VAT export rebate system effectively reduced the tax burden for solar exporters. When a Chinese manufacturer sold panels internationally, the government refunded a portion of the domestic value-added tax they had already paid. Originally 13%, the rebate was cut to 9% in December 2024. On April 1, 2026, it becomes zero.
This is not an anti-dumping measure imposed from outside. It is China’s own industrial policy deliberately unwinding a subsidy mechanism that the China Photovoltaic Industry Association itself publicly supported the removal of — arguing it had fuelled unsustainable price competition and created trade friction risks with European and American partners.
What Manufacturers Are Doing Right Now
Since January 2026, leading manufacturers including Trina Solar, LONGi, and JA Solar have announced price increases — some twice within a single month — as they pre-position for the rebate removal. According to ARC Advisory, Trina raised mid-size module prices by approximately $0.03/W from its previous range. This is not panic; it is an orderly, industry-wide repricing of the cost floor.
Manufacturers have also been front-loading Q1 2026 shipments. Every container that leaves Chinese ports before April 1 still carries the 9% rebate benefit. After April 1, the economics change permanently. Chinese domestic industry analysts at Shanghai Metals Market project post-April demand could fall 5–10% before stabilising at a new, higher price level.
The Pre-Deadline Rush: Risk and Opportunity
The rush to ship before April 1 has created a brief window where motivated suppliers may be willing to negotiate competitively to move volume. But it also creates real supply-chain risks:
- Manufacturing lead times are compressed. Everyone is trying to produce and ship at once.
- Port congestion at Chinese export hubs (Ningbo, Shanghai, Shenzhen) is elevated as Q1 volumes surge.
- Freight space for March departures is tightening — book now or pay spot premiums.
- Quality inspection timelines may be shortened under production pressure. Build inspection into your contracts explicitly.
Critical timing note: The applicable VAT rebate rate is determined by the export date on the customs declaration — not the date of manufacture, not the date of booking, not the date of arrival. A panel manufactured in March but declared for export on April 2 gets zero rebate. If you are negotiating Q1 contracts, ensure your supplier specifies customs export dates explicitly, and build in buffer for documentation delays.
The Raw Material Squeeze Behind the Scenes
Freight and VAT policy are the headline pressures. Below those are structural raw material shifts that will outlast any single geopolitical event.
Silver: A Historic Cost Inflection in Solar Cell Manufacturing
Silver is the critical conductive material in solar cell metallisation — the process of forming ultra-fine grid lines on wafers to collect electricity. It is screen-printed as a paste, fired at high temperature, and consumes roughly 86 milligrams per TOPCon cell (as of 2025 CPIA data).
Silver hit a record price of $83.62 per ounce on December 28, 2025. According to OPIS analyst Hanwei Wu, silver rose approximately 180% from trough to peak across 2025 — one of the fastest sustained moves in industrial precious metals history. Silver prices have been highly volatile in early 2026: after trading around $75/oz in early January, the metal surged past $100/oz before a sharp mid-February correction. As of publication, silver is trading in the $82–$95/oz range — still historically elevated and significantly above its multi-year average, with the added disruption of conflict-driven safe-haven demand now reinforcing the floor.
The consequences for cell manufacturers are severe. OPIS reports that silver paste now accounts for up to 30% of total cell production costs — a share so large that, for certain high-efficiency cell architectures, silver paste has become one of the single largest individual input costs in the entire manufacturing process. This cost pressure has proven extremely difficult to pass downstream: OPIS data shows FOB China TOPCon module prices rose only about 15% from trough to peak in 2025, far below silver’s move of ~180%.
The industry response is real but slow. HJT cells are shifting toward silver-coated copper paste at scale. TOPCon manufacturers are reducing silver loading — down to 86 mg/cell from over 100 mg two years ago. But silver exposure will remain a structural cost challenge for the next two to three years at minimum.
Methanol, PV Glass, and the Iran Supply Disruption
Iran is one of the world’s largest methanol producers, with annual capacity of approximately 17 million tonnes according to Blooming Global — and China has been its primary buyer. Methanol is a critical feedstock for producing the low-iron glass used in bifacial solar panels. China’s methanol imports from Iran had already been declining — falling from 1.47 million tonnes in 2024 to approximately 815,000 tonnes in 2025, partly due to sanctions-related sourcing shifts.
The February 28 strikes and the Hormuz closure have now compounded this disruption sharply. China’s methanol futures hit the daily trading limit on March 2, according to Mysteel. Port inventories that had built up through late 2025 are now being drawn down faster than they can be replenished through alternative supply routes. The duration and scale of the price impact on PV glass production costs will depend entirely on how long the conflict continues — but supply-side tightness is confirmed and ongoing.
Polysilicon: Oversupplied but Recovering
Polysilicon tells a more nuanced story. Severe oversupply has pressured prices downward through most of 2025, with global spot prices sitting around $6–7/kg in early 2026 — substantially below the peaks of 2022–23 but recovering from 2024 lows. Several smaller Chinese producers have already exited the market or curtailed output. A supply-side correction that tightens polysilicon availability remains a real medium-term risk, particularly if the conflict disrupts China’s energy-intensive production infrastructure.
Project Cost Modelling: Real-World Financial Impact
Theory matters less than money. Here is a simplified but realistic model of how these pressures affect a 5 MW ground-mount solar farm — a common commercial or community-scale project size. All figures are illustrative; actual costs vary significantly by geography, specification, and supplier terms.
| Cost Category | December 2024 | March 2026 (Current) | Post-April 2026 (Projected) |
|---|---|---|---|
| Modules (5,000 kW) | $450,000 at $0.09/W | $600,000 at $0.12/W | $675,000 at $0.135/W |
| Freight (10 containers) | $18,830 | $21,230 | $24,000–27,000 |
| Module + Freight Subtotal | $468,830 | $621,230 | $699,000–702,000 |
| Balance of System, Labour, Permits | ~$1,200,000 | ~$1,250,000 | ~$1,250,000 |
| Total Project Cost | ~$1,669,000 | ~$1,871,000 | ~$1,949,000–1,952,000 |
| Cost per Watt | $0.33/W | $0.37/W | $0.39/W |
| vs December 2024 | — | +$202,000 (+12.1%) | +$280,000–283,000 (+16.8%) |

What a 12–17% Total Cost Increase Means for Project Viability
For a project with a strong return profile, a 12–17% increase in total cost is painful but manageable. For a project already at the margin — or for a developer locked into a fixed-price offtake agreement priced on 2024 assumptions — it can eliminate the return entirely.
The most exposed developers are those who:
- Have signed EPC contracts at fixed prices without commodity adjustment clauses
- Are competing in regulated tariff markets where PPA prices are set by authority
- Are sourcing primarily or exclusively from Chinese suppliers with no alternative supply agreements in place
- Have project finance arrangements that assumed a specific module cost-per-watt
If any of these describe your current projects, a contract review — specifically of force majeure clauses, commodity pass-through provisions, and change-in-law language — should happen this week, not next month.
Seven Actions Solar Importers Should Take Right Now
The situation is volatile but it is not unmanageable. Here is a structured, priority-ordered action plan for procurement teams.
- Lock in pre-April contracts — with written customs export date commitments. The VAT rebate rate applies based on the export date on the customs declaration. Oral commitments are worthless. Get signed contracts that specify the module export date and make the pre-April pricing conditional on that date being met. Build in a price adjustment clause if the export date slips past April 1.
- Calculate your full landed cost, not your FOB price. The module price is the starting point. Add: freight at current elevated rates, marine war-risk insurance (now substantially higher for routes near the Middle East), import duties, customs brokerage fees, and inland delivery. Your actual procurement cost per watt is significantly higher than the headline FOB number — and that is what your project budget must reflect.
- Review force majeure and change-in-law provisions in all active contracts. Carriers are testing force majeure clauses in response to the Hormuz closure. Suppliers may invoke change-in-law relief for the April 1 VAT change. Understand exactly what protections you have — and where your exposure sits — before a counterparty raises it first.
- Add 3–4 weeks of buffer to all project timelines with Q2 deliveries. Vessels rerouting around the Cape of Good Hope add 10–14 days on Asia-Europe routes. Port congestion at alternate hubs adds further delay. If you have a hard installation deadline in Q2 2026, you need buffer built in now. Delays that seemed unlikely two weeks ago are now near-certainties on certain routes.
- Seriously review your cargo insurance coverage. War-risk insurance premiums for Gulf transits had already risen sharply before the strikes. Policies written before February 28 may have coverage gaps for the current conflict scenario. Review your marine policy this week — specifically the war exclusions, the geographic scope, and whether your insured value reflects current replacement costs.
- Diversify your supplier base, even partially. China controls over 80% of global module manufacturing. That is not changing in the short term. But having even one alternative qualified supplier — whether in Southeast Asia (Vietnam, Thailand), India, or elsewhere — gives you negotiating leverage and risk mitigation that a single-source strategy cannot provide. Even 15–20% of your volume from an alternative source changes your risk profile meaningfully.
- Monitor three specific signals daily. First: Strait of Hormuz status — any confirmed reopening will ease freight pressure immediately. Second: any Chinese government announcement modifying or delaying the April 1 VAT timeline (currently considered unlikely, but watch official MoF channels). Third: Brent crude price — sustained above $90/barrel is a reliable proxy for carrier rate pressure across all trade lanes.
The Long Game: Why Solar Fundamentals Remain Strong
It would be easy to read this article and conclude that solar imports from China have become prohibitively expensive or unreliable. That conclusion would be wrong — and the market data confirms it.
According to the China Photovoltaic Industry Association, China is expected to add 180–240 GW of domestic solar capacity in 2026 alone. Global solar capacity additions — while projected to record a modest year-on-year decline for the first time in approximately two decades — are forecast at approximately 649 GW globally in 2026, according to BloombergNEF’s December 2025 estimates. That marginal decrease from 655 GW in 2025 represents the first projected annual decline in nearly twenty years. It is still an enormous market. Supply chains at that scale do not collapse because of a single conflict, even a severe one.
There is also a more fundamental point. Every major energy crisis in history has ultimately accelerated the transition away from fossil fuels. The 1973 oil shock drove the first wave of energy diversification. The 2021 gas price crisis accelerated European solar policy. This conflict — with oil prices surging and European gas prices spiking — is already generating exactly the same political and economic dynamic.
- Middle Eastern countries are revising solar installation targets upward for 2026–2027, driven by energy security imperatives rather than cost alone
- European governments are explicitly linking renewable buildout to reduced dependence on Middle Eastern oil and gas — creating new policy-driven demand for solar
- Energy storage demand is surging across regions experiencing power disruptions, creating integration opportunities alongside panel sales
- Chinese manufacturers are accelerating overseas production expansion — including in Egypt’s Suez Canal Economic Zone — to shorten supply chains and reduce export-side policy risk
- The VAT rebate removal will accelerate industry consolidation around well-capitalised manufacturers with genuine technology differentiation — which is ultimately good for buyers who prioritise quality over the lowest possible spot price
If your business model was viable in late 2024, it is almost certainly still viable now. The parameters have changed. Margins are tighter. Lead times require more buffer. Budgeting requires more precision. Contracts need more careful drafting. But the market opportunity — driven by energy security demand that this very conflict is intensifying — is, if anything, larger than it was a year ago.
Build your supply chain for resilience, not just cost minimisation. The businesses that navigate this period well will be those that locked in supply early, diversified their risk intelligently, and maintained strong supplier relationships through the disruption. Those are the businesses positioned to capture the growth wave that follows.
◆ ◆ ◆
Summary: The Three Things to Act On
First: Costs are up 30–40% from December 2024 and are heading higher. This is not temporary volatility. It reflects structural changes — in policy, raw materials, and geopolitics — that will persist through 2026 at minimum. Build your procurement budgets accordingly.
Second: April 1 is a hard, confirmed deadline. The VAT rebate elimination will add approximately 9% directly to export costs. Combined with silver and methanol pressures, total module prices are expected to rise 10–15% from current levels post-April. Every week of delay on locking in pre-April supply has a quantifiable cost.
Third: Solar energy is becoming more strategically important, not less. The energy security argument for solar has never been stronger than it is today. Short-term supply chain stress is real. The long-term trajectory is unambiguous. Stay the course — but manage the near-term carefully.
