The expansion of Trump solar tariffs in 2025 is having a major impact on the U.S. solar industry. New and steep solar panel tariffs on imports from Southeast Asian countries—including Vietnam, Malaysia, Thailand, and Cambodia—have been set as high as 3,500%, targeting companies accused of helping Chinese manufacturers bypass earlier trade duties.
These changes are driving up costs for solar modules and causing delays, especially for contractors already managing tight margins. Despite these challenges, residential solar prices reached a record low of $2.50 per watt in early 2025, according to EnergySage, showing that some price pressure is still being offset by competition and installer efficiency.
In May 2025, the U.S. and China agreed to a temporary 90-day reduction in overall trade tariffs, but this agreement does not include solar products. That means the new U.S. solar panel import tariffs 2025 will continue to affect supply and pricing for installers throughout the year.
Understanding the 2025 Solar Panel Tariffs
Solar companies are once again adapting to a rapidly changing trade environment. In 2025, the U.S. Commerce Department finalized a new round of solar panel tariffs, building on previous trade actions initiated under the Trump administration. These Trump solar tariffs are reshaping how contractors approach pricing, sourcing, and supply chain planning.
The newly announced solar tariffs 2025 are expected to take effect by mid-year, with enforcement beginning approximately 90 days after the final ruling. That gives solar companies a narrow window to adjust their procurement strategies and secure materials before the new costs hit.
A Look at 2025 Trump Solar Tariffs and Their Expansion
In April 2025, the U.S. Commerce Department finalized a sweeping trade decision that’s reshaping the solar industry. The newly expanded Trump solar tariffs now apply to a broader range of imported equipment, including solar panels, inverters, and battery storage systems, driving up costs across the supply chain. These updated solar panel tariffs for 2025 are creating major challenges for contractors, developers, and EPCs already working with tight margins.
To understand the context, it’s important to revisit the two main types of earlier tariffs:
Section 201 Safeguard Tariffs: Introduced in 2018 under the Trump administration, these tariffs targeted imported crystalline silicon PV modules and cells to protect domestic manufacturers.
AD/CVD (Anti-Dumping and Countervailing Duties): These duties, also initiated during Trump's term, were aimed at penalizing solar manufacturers in countries like China for unfair pricing and government subsidies.
The 2025 expansion goes further, adding steep tariffs on additional categories like inverters and batteries—equipment that wasn’t previously subject to such heavy duties. According to reporting from PV Magazine, the newly finalized Trump solar tariffs range from 50% to over 120% for some imported modules, far exceeding the initial forecasts of analysts.
This sharp increase in equipment costs is already affecting project planning, bidding strategies, and installation timelines. From procurement delays to rising quotes for residential and commercial customers, the effects of the solar tariffs 2025 are rippling through the entire market.
Which Products Are Most Affected by Trump Solar Tariffs?
Not every solar product is equally impacted by the new trade measures. The latest solar panel import tariffs primarily target:
Crystalline silicon PV modules and cells from Southeast Asia — especially from Vietnam, Malaysia, and Thailand. These countries have become dominant suppliers for the U.S. solar market in recent years, so the new solar panel tariffs 2025 have a direct impact on module pricing and availability.
Battery storage components have also been pulled into the new tariff structure. This expansion introduces additional complexity for solar + storage projects, increasing costs and contributing to wider solar supply chain uncertainty.
Exemptions From New Solar Tariffs
While the 2025 expansion of Trump solar tariffs has raised costs on many imported components, some products remain exempt. Knowing which equipment is excluded from the new solar panel tariffs 2025 can help contractors plan smarter and reduce procurement risks.
Thin Film Solar Panels
Thin-film solar modules, particularly cadmium telluride (CdTe) products manufactured by U.S.-based companies like First Solar, remain largely exempt from the new tariffs. Because they are made with different materials than crystalline silicon (c-Si), thin-film modules fall outside the scope of Section 201 Safeguard Measures and AD/CVD rulings.
Thin-film technology has traditionally been used in utility-scale solar farms, thanks to its durability in high heat and better performance under diffuse light. But in 2025, it’s also gaining traction in commercial rooftops and larger residential solar systems, where slightly larger arrays can help offset the lower efficiency of these modules.
First Solar is the dominant U.S. manufacturer of thin-film CdTe modules, with large-scale production facilities in Ohio, Alabama, and a recently expanded plant in Louisiana.
U.S.-made Crystalline Silicon Panels
U.S.-manufactured crystalline silicon (c-Si) modules are also generally exempt from the latest U.S. solar panel import tariffs 2025. Installers sourcing from domestic manufacturers can avoid much of the tariff-related price volatility. However, demand for U.S.-made modules has surged, and lead times may be extended through the second half of 2025 as production scales up.
Key players include:
Qcells USA (Hanwha Qcells)
Operates major manufacturing plants in Dalton and Cartersville, Georgia.
Combined, these facilities are expected to produce up to 8.4 GW of solar panels annually by the end of 2025.
Runs a 1.1 GW module production facility in Washington state.
Expanding operations with a new plant in Fort Mill, South Carolina, aiming for 1 GW of solar cell production capacity.
Based in San Antonio, Texas, producing both modules and cells domestically.
Investing $265 million to add 2 GW of solar cell production capacity, with completion expected in early 2026.
Manufactures high-efficiency crystalline silicon modules in Minnesota.
Partnered with Suniva and Corning to produce modules with up to 66% domestically-produced components.
Solar Installer Impact From Trump Solar Tariffs
The expanded Trump solar tariffs in 2025 are already reshaping the solar installation landscape. With steep new duties on imported modules and components, solar contractors are dealing with rising costs, tighter margins, and increased uncertainty in the supply chain. These U.S. solar panel import tariffs 2025 are having direct and immediate effects on project planning, pricing, and overall system affordability.
Rising Module Costs and Project Budget Pressure
One of the most noticeable impacts of the 2025 solar panel tariffs is the sharp increase in module prices, particularly for crystalline silicon PV panels sourced from Southeast Asia. Recent industry reports show that prices for imported modules from Vietnam, Malaysia, and Thailand have jumped by 50% to over 100% in some cases.
For solar installers, this means:
Thinner or disappearing profit margins
Mid-project pricing adjustments that can frustrate customers
Less competitive bids in residential markets
Tighter project viability for larger commercial systems
Installers already operating on slim margins are now forced to build in pricing buffers—or risk losing money on signed contracts.
Procurement Challenges & Supply Chain Disruptions
Beyond price increases, the solar tariffs 2025 have introduced major supply chain disruptions. Sudden changes in tariff enforcement have led to:
Inventory tightening by suppliers, prioritizing high-volume buyers
Revised delivery schedules and delayed shipments
Unpredictable product availability, making it harder to match approved module models to job specs
This uncertainty creates a ripple effect during permitting, engineering, and installation. Contractors must now plan for longer lead times and consider that the modules they specified for a project could become unavailable—or delayed—by the time permits are approved.
Many companies are being forced to order equipment earlier than usual, tying up cash flow and increasing warehousing needs. Others face the risk of scrambling for alternate products late in the process, potentially affecting interconnection approvals and installation schedules.
How Trump Solar Panel Import Tariffs Are Disrupting Project Timelines
The effects of the 2025 solar panel tariffs aren’t limited to costs—they’re hitting project schedules and customer relationships, too. Managing expectations early is now critical for avoiding misunderstandings and project churn.
Solar Project Delays and Scheduling Risks
One of the biggest risks right now is project delays tied to module and battery shortages.
Contractors are reporting longer wait times for securing panels and critical components, even for projects that were previously ready to move forward.
Combined with permitting slowdowns in some jurisdictions, supply chain issues are causing construction timelines to slip, sometimes by weeks or even months.
To minimize the solar installer's impact, companies need to communicate clearly with customers about potential delays and adjust project timelines at the contract stage, not after issues arise. Transparency around procurement realities helps protect customer relationships and maintain trust during a volatile market.
Impact of Solar Tariffs on Energy Storage Projects
The challenge is even greater for installers managing solar + storage projects.
Battery storage components are now covered under the expanded Trump solar tariffs, leading to price hikes and availability constraints across multiple product lines.
Installers must juggle sourcing both panels and batteries under far less predictable conditions.
This dual pressure complicates incentive-driven projects in states like California, New York, and Massachusetts, where solar + storage adoption is supported by financial rebates. Rising costs and extended lead times may affect eligibility windows for these programs, meaning installers must stay ahead of procurement challenges to avoid losing incentive dollars.
Smart Strategies for Navigating the 2025 Solar Tariffs
With the 2025 Trump solar tariffs reshaping the market and fueling solar supply chain uncertainty, companies that stay flexible and plan ahead will be in the strongest position to succeed. Solar industry experts at SEIA recommend taking these proactive steps to manage risks, control solar module costs, and minimize solar installer impact:
1. Diversify Supplier Relationships
One of the most effective ways to manage the fallout from new solar tariffs is to broaden your supply network. Building a more diversified supplier base helps installers protect against sudden pricing spikes, inventory shortages, and project delays.
Avoid relying too heavily on panels or equipment from a single region—especially countries like Vietnam, Malaysia, and Thailand that are heavily targeted by the new tariff measures.
Explore working with U.S. solar panel manufacturers or sourcing tariff-exempt technologies like thin-film solar modules, which remain largely unaffected by the latest trade rulings.
2. Prioritize Early Procurement and Inventory Management
As solar module costs rise under the new tariff regime, locking in key components early is more important than ever. Companies that get ahead of procurement bottlenecks will be better positioned to deliver projects on time and on budget.
Order panels, inverters, and storage equipment earlier in project timelines to secure pricing and avoid last-minute surprises.
Build longer lead times into project schedules and plan for potential delivery delays due to solar supply chain uncertainty.
3. Strengthen Contract Language to Manage Risk
Given the volatile pricing environment, tightening up contract terms is essential. Smart contract language helps reduce financial exposure for both installers and customers when unforeseen changes hit the market.
Use escalation clauses that allow for adjustments in pricing if material costs spike unexpectedly.
Incorporate flexible procurement models that reflect the reality of tariff-driven supply risks.
4. Monitor and Adapt to Storage Tariff Impacts
It’s not just solar modules under pressure—the latest Trump solar tariffs also cover many energy storage components. Solar + storage projects may face new cost structures in 2025, and being nimble on storage procurement will be key to keeping bundled projects competitive.
Keep a close eye on battery storage pricing trends and availability.
Consider expanding partnerships with manufacturers that have U.S.-based production or diversified, tariff-exempt sourcing strategies.
5. Stay Updated on Tariff Changes and Compliance Issues
The tariff environment is still evolving, and staying informed is essential to managing both costs and compliance obligations.
Monitor updates from the Department of Commerce, Customs and Border Protection, and IRS guidance—especially for projects claiming tax credits tied to domestic content or labor standards.
6. Advocate for Smarter Solar Trade Policies
While solar companies can’t control federal policy, staying engaged is critical for protecting the industry's future. Collective industry action can help push for smarter, more predictable solar trade policies that support long-term growth instead of sudden market disruptions.
Contractors, EPCs, and suppliers are encouraged to work with trade organizations, submit comments during public tariff review periods, and advocate for clear, stable, clean energy trade rules.
“Policymakers can’t champion American energy dominance while imposing tariffs that cripple the industries driving it," says Patrick McCabe, co-founder and president of GreenLancer. "The U.S. needs forward-looking trade policies that fuel growth—not reactionary measures that undermine our path to true energy leadership.”
Quick adjustments based on regulatory updates can help protect project eligibility and reduce costly mistakes.
Looking Ahead: Future Policy Risks and Opportunities for Installers
While the 2025 Trump solar tariffs have created immediate challenges, smart solar companies are already thinking about the next waves of policy and market changes. Staying proactive will be critical to minimizing future solar installer impact and navigating ongoing solar supply chain uncertainty.
Potential for New Solar Trade Disputes
Ongoing investigations into anti-circumvention practices could trigger even more trade actions in 2025 and 2026. Political shifts could bring new solar tariffs or adjustments to existing duties, adding fresh complexity to equipment sourcing and project pricing.
Installers can help advocate for a more stable clean energy market by engaging with industry groups, submitting comments during tariff review periods, and staying visible in the conversation around smart solar trade policy.
Long-Term Solar Installer Strategies for Supply Chain Resilience
To prepare for continued uncertainty, solar companies should:
Build strong relationships with multiple distributors and manufacturers, including U.S. solar panel manufacturers, to create more sourcing flexibility.
Prioritize early procurement of modules, inverters, and storage components to secure pricing and minimize delays caused by solar supply chain uncertainty.
Stay connected with advocacy groups like SEIA, which help represent installer interests in policy debates.
By combining flexible procurement with smart advocacy, installers can turn today’s challenges into long-term growth opportunities.
