Navigating Domestic Content in a Modular, Mix-and-Match Market

A practical field guide for modeling domestic content earlier, preserving optionality and documenting the supply chain behind the 10% adder

By Kyle Burak, Vice President of Sales and Business Development, Bila Solar

At CLEANPOWER 2026 in Houston earlier this month, I spoke with developers, EPCs, asset owners and clean-energy partners about one of the most important and misunderstood issues shaping solar-project planning today: domestic content.

For a long time, the market treated domestic content as a binary question: Is the module domestic or not? That framing no longer reflects how projects are actually being planned, financed and built.

Today, domestic content is a configurable procurement strategy. Developers, EPCs, distributors, asset owners and financing partners are looking for the right combination of U.S.-made and compliant components that can support project economics without creating unnecessary cost, delay or compliance risk.

That is the idea behind Pick, Place and Perform, the framework I shared at CLEANPOWER. Project teams need to pick the right configuration, place it into the project plan early and perform with documentation that can stand up to diligence.

Domestic content is no longer all domestic or nothing

Slide 2: Domestic content is a configurable procurement strategy

The old question was simple: Are domestic content modules available? That usually led to a single-sourcing mindset. Find one product, check one box and move on.

The new question is more strategic: Which mix of products gets the project to the 10% domestic content adder without adding cost, delay or compliance risk?

That mix may include U.S.-made solar cells, a domestic frame, compliant imported components, domestic balance-of-system elements and the documentation needed to prove provenance across the supply chain.

Domestic content is about how each eligible component contributes to the overall project calculation and how that calculation aligns with the project’s placed-in-service window, procurement schedule and financing assumptions.

For project teams, this means domestic content needs to be modeled before procurement decisions are locked. Waiting until late-stage diligence creates risk. By then, the project may have limited flexibility to change suppliers, adjust component strategy or strengthen documentation.

Policy dates, project dates and financing dates do not move at the same speed

Slide 3: The target keeps moving

One of the biggest challenges in the current market is that the targets keep moving.

Domestic-content-percentage requirements step up over time. FEOC compliance requirements are also becoming a more central part of procurement and financing conversations. At the same time, project development schedules, financing deadlines and supply-chain realities rarely move in a straight line.

That creates a planning challenge. A project that looks straightforward in one quarter may face a different set of requirements by the time it reaches procurement, financing or placed-in-service milestones. Developers are trying to preserve eligibility and economics across a moving timeline.

That is why the strategic move is not to chase one percentage. It is to model the path that fits the project. For some projects, the priority may be maximizing domestic content value. For others, the more immediate issue may be preserving schedule certainty, reducing FEOC exposure or avoiding a supply-chain configuration that creates documentation gaps.

The right strategy depends on when the project will be placed in service, how the tax credit value is being underwritten and what proof will be required by financing partners. Project teams should review the latest IRS and Treasury guidance, including the domestic-content elective safe-harbor tables, and work closely with tax and legal advisors on begin-construction and safe harbor strategies.

Safe harbor note: As of this draft, the begin-construction/safe harbor landscape has recently changed. On June 6, 2026, the U.S. District Court for the District of Columbia vacated IRS Notice 2025-42, which had limited use of the 5% safe harbor for most larger solar projects. Because begin-construction and safe harbor guidelines continue to evolve, project teams should review the latest IRS guidance, monitor current legal developments and consult qualified tax counsel before making procurement or financing decisions.

What can actually build the domestic content stack?

Slide 4: U.S.-made components and assigned value ranges

A practical domestic content strategy starts with understanding what can actually move the calculation.

Not every component contributes the same way. Some pieces of the stack have a much larger impact than others.

Solar cells can represent a significant portion of the domestic content value. Frames can also matter, especially as more U.S.-made frame options become available. Backsheets, junction boxes and other components may contribute smaller percentages, but they can still help close a gap depending on the project configuration.

The key is to understand which components are available, which are constrained and how each one contributes to the project’s domestic-content calculation. This is where early modeling becomes essential.

A project team may not need every component to be domestic to pursue the adder, but it does need to understand which combinations are viable, available and documentable. That is the difference between a procurement strategy and a hope.

Sourcing FEOC-compliant solar panels

Slide 5: FEOC-free sourcing requirements

Domestic content is only one part of the conversation. FEOC compliance is now a potential barrier that has to be addressed early.

The market is paying closer attention to ownership, control, sourcing, documentation and exposure across the supply chain. For developers and financing partners, this is a bankability issue. A project may have an attractive domestic-content strategy on paper, but if the supply chain introduces FEOC risk or lacks clear documentation, that value can become harder to finance.

This is why sourcing decisions need to be evaluated through two lenses at the same time: Can the configuration support the domestic-content strategy, and can the supplier provide the transparency and documentation needed to support diligence? The answer has to be yes to both.

Model the configuration before procurement is locked

Slide 6: Example configurations and FEOC-free thresholds

Once you move from theory to project planning, the question becomes more specific: Which configuration actually works?

There may be multiple paths to a compliant and financeable structure. Some configurations may clear one threshold but not another. Others may provide more cushion for future requirements or financing scrutiny.

That is why project teams should avoid treating domestic content as a last-minute procurement label. The better approach is to run scenarios early. Compare component combinations. Understand the margin between the project’s calculated percentage and the required threshold. Identify which components are essential, which are optional and which introduce unnecessary risk.

A configuration that barely clears a threshold may work in theory, but it may not be the best strategy if the project faces documentation, timing or substitution risk later.

Preserve optionality in a moving market

Slide 7: Preserving optionality across configurations

The value of optionality is easy to underestimate until a project loses it.

Supply availability can change. Guidance can evolve. Financing partners can ask new questions. A supplier that looked acceptable at the beginning of the process may not be the best fit by the time diligence begins.

This is why the strongest domestic-content strategies are built around a set of options.

A modular, mix-and-match approach allows project teams to evaluate different combinations of domestic and compliant components while still protecting schedule and cost discipline.

The goal is to avoid being locked into a single path that cannot adapt when the project’s needs change. That is especially important in today’s market, where domestic manufacturing capacity, FEOC compliance, safe-harbor planning and financing assumptions are all connected.

The profitability playbook

Slide 8: Pick, place and perform

Domestic content is easiest to monetize when it is modeled early and documented continuously.

There are five practical moves project teams should make:

  • Model earlier. Include the domestic-content adder in the initial project pro forma, not as a late-stage upside case.
  • Procure options. Evaluate multiple domestic supply paths early so the project is not dependent on one configuration.
  • Validate components. Confirm domestic content percentages, FEOC compliance and supplier documentation before procurement decisions are final.
  • Align capital. Make sure the financing strategy reflects the documented domestic-content path and the level of diligence required.
  • Preserve optionality. Design the supply chain so the project can adapt if policy, availability or project timing changes.

This is the shift: Domestic content success comes down to three moves.

Pick the right configuration. Place it into the project plan early. Perform with documentation that stands up to diligence.

That is how domestic content becomes a project economics strategy.

Keeping projects moving

Slide 9: Contact

At Bila Solar, we are having these conversations every day with developers, EPCs, distributors and asset owners who are trying to make near-term project decisions in a fast-moving market.

The common thread is clear: The projects best positioned are those that model domestic content early, ask harder supply-chain questions and make documentation part of the procurement process from the start.

Domestic content is no longer all-or-nothing. It is a strategy. And the teams that treat it that way will be in a stronger position to capture value, manage risk and keep projects moving.
