Is FEOC-Compliant Equipment Actually Available in 2026?

The gear is out there. The hard part is documenting it.

Featuring Caleb Quaid, President, Clean Energy Help. Adapted from the SunSmart Engineering × Clean Energy Help × FlaSEIA panel, Commercial Solar in 2026. Watch the clip: "08 - Is FEOC-Compliant Equipment Actually Available.mp4".

When the One Big Beautiful Bill Act (OBBBA) was signed on July 4, 2025, it attached new Foreign Entity of Concern (FEOC) restrictions to the clean energy tax credits. FEOC limits how much of a project's content can come from prohibited foreign entities, which the statute ties to China, Russia, North Korea, and Iran. For solar manufacturing, China is the one that matters. So the worry was obvious. If so much of the supply chain runs through China, will there be compliant equipment to buy in 2026? The panel's answer was more reassuring than most people expected.

Availability is better than you'd think

Caleb Quaid runs Clean Energy Help, which was supporting roughly $750 million in clean energy projects nationwide at the time of the webinar. He has watched this market closely, and he thinks the supply worry is fading.

"It's less and less of a problem now," Caleb said. "It's an evolving landscape, and manufacturers are getting a lot better at identifying and documenting this stuff. I saw another notification today of a supplier that just went through their due process and now feels they can document FEOC compliance. The market's evolving, and I've seen pretty good availability of product that meets FEOC and domestic content requirements, which surprises me, because you'd think there'd be huge demand that would outstrip supply, but I'm not seeing that."

That's worth sitting with. A sudden compliance requirement plus a constrained supply chain should have meant spiking prices and long lead times. It mostly hasn't played out that way. Manufacturers moved fast to qualify product lines, document their sourcing, and certify compliance, and new suppliers keep joining the list. A 2026 solar project has to hit a 40% non-FEOC threshold (storage is higher at 55%), and the equipment to get there is generally on the shelf.

A quick note on terms. FEOC compliance is measured through a Material Assistance Cost Ratio (MACR), and the threshold steps up over time, to roughly 45% for solar starting in 2027. Domestic content is a separate and higher bar, around 50% for projects beginning in 2026, and it carries a +10% bonus on the base credit. Both can be documented against a published IRS safe-harbor table (referenced in the webinar as Notice 2025-08) that assigns cost percentages to system components, so you don't have to trace every screw by hand.

The real work is in the paperwork

If the equipment is available, the risk has to live somewhere else. It lives in the documentation, and that's where Caleb says his team spends its time.

"The key work we're doing is looking at the letters, looking at the model numbers coming in, making sure those are referenced in the letter and the manufacturer is certifying that, and reviewing those," Caleb explained. "There are a few hot topics that need to be looked at in those letters to de-risk the project."

The deliverable that protects your credit isn't the pallet of modules. It's the manufacturer's certification letter that ships with them. And that letter only helps you if the exact model numbers on your order are the ones it names and certifies. A compliance letter that references a different SKU than what shows up on the truck is, for your purposes, close to worthless.

Why the SKU is everything

Here's the trap, and it's an easy one to fall into. From the engineering side, the FEOC-compliant version of a product is often the same part you already know, just a different variant.

Troy Phelan of SunSmart Engineering put it plainly. "The FEOC-compliant version is usually the same exact part number, just with something like a '-US' or some version of that. You really just have to zoom in on that SKU and double, triple check before you complete your order."

That's the catch Dustin Waite flagged on the panel too. The same manufacturer can make a compliant and a non-compliant variant that look nearly identical. Same form factor, same spec sheet, same picture on the line card. What separates the one that keeps your tax credit from the one that quietly kills it might be a small suffix on the model number.

So the engineering barely changes. The design is the design, and the compliant variant usually drops right into the same plan set. What changes is the procurement discipline. Before you place an order, confirm that the exact SKU you're buying is the FEOC-compliant variant, that the same model number is named in the certification letter, and that the manufacturer is actually certifying compliance for that specific part rather than gesturing at it in general.

Miss the suffix and you can order a near-twin of the right product, watch it pass every visual check on site, and only find the problem when you try to substantiate the credit. By then it's expensive to fix.

The bottom line

• The supply fear was overblown. Per Caleb, FEOC- and domestic-content-compliant product has shown "pretty good availability," and demand hasn't outstripped supply the way many predicted.
• Manufacturers are catching up fast. New suppliers keep completing their due diligence and certifying compliance, so the compliant list keeps growing.
• The risk moved from sourcing to documentation. The protective deliverable is the manufacturer's certification letter, not just the hardware.
• The letter has to name your exact model numbers. A certification that references a different SKU doesn't cover your order.
• Watch the suffix. Compliant and non-compliant variants can look almost identical, often separated only by a "-US"-style tag. Double- and triple-check the SKU before you finalize.

How SunSmart Engineering can help

SunSmart Engineering builds the plan sets that carry these compliant variants, and because the compliant SKU usually drops into the same design, we help you confirm the part numbers on your engineering match the part numbers on your order and the ones named in your certification letters. We're a full-service engineering firm for solar and storage, Florida-based and working nationwide, and we're happy to be a second set of eyes before you commit to a purchase.
