[A] Overview & Disclaimers

The One Big Beautiful Bill Act (OBBBA) of 2025 introduced additional complexities to residential solar supply chain & hardware processes. To avoid milestone disruptions, it's incumbent on installers to ensure they have a strong grasp on our AVL and key hardware concepts & requirements.

Key Terms & Concepts to Understand:

AVL

Details: Our Approved Vendor List, providing all available equipment eligible for solar installations.

Goal: Installers are responsible for adhering strictly to our AVL when executing installations.

FEOC

Details: Foreign Entity of Concern (China, Russia, N.Korea, Iran)

Focus: Who owns and controls the companies in a supply chain

Goal: Starting in 2026, certain % of project value cannot be tied to a Foreign Entity of Concern, mainly focused on China.

Domestic Content

Details: An optional program whereby installers can use US-based components to gain additional EPC payment value.

Focus: Where the equipment is manufactured

Goal: Option to gain additional ITC value via USA-based components

Safe Harbor

Details: An equipment procurement process whereby Palmetto secures equipment for our solar partners, in advance, in order to maintain certain regulatory conditions -- including tax credit eligibility (thereby preserving our competitive pricing).
Focus: “Commence construction” via equipment purchase in advance of December 31, 2025 (FEOC Compliance) or July 3, 2026 (Extend ITC)
Goal: To [1] Extend 30% TPO tax credit value into 2030, [2] Ensure FEOC compliance, [3] Maintain Domestic Content thresholds, and/or [4] Mitigate equipment shortages

Each of these items are covered in detail below, simply click the dropdown to view full guides.

General Disclaimers

Click to View

Right to Exclude: LightReach reserves the right to exclude individual products from approved manufacturers based on quality considerations.

Inverter Extended Warranty: Installer must purchase the extended 25 year warranty, if applicable (e.g. SolarEdge). Installers must be a certified/registered with the manufacturer if the warranty requires it to maintain the 25 year warranty

PV Module Warranty: All modules must have a 25 year product & production warranty.

Racking: Systems & attachments must be certified for solar racking installation.

Cellular: Systems should include cellular devices with 5 year data plans. If cellular service is confirmed unavailable, LightReach will review alternative communication methods on a case by case basis.

Consumption: Systems require whole home consumption monitoring.

Revenue Grade Metering: Inverters require revenue grade metering. Additional equipment may be required for production or consumption monitoring and reporting.

Bundled Units: LightReach currently does not approve module level power electronics added to PV modules at the manufacturer facility. (e.g. Optimizers and Microinverters attached to the module directly and shipped as a single unit)

Size/Use: Solar modules should be recommended for residential rooftop or ground mount installations. (Commercial and Industrial sized modules are not generally approved to avoid issues with serviceability in the future)

Manufacturer Specifications: All components used on site must follow manufacturer specifications, including (but not limited to) module compatibility with microinverters/optimizers used, string sizing, overcurrent limits, etc.

Application: Applies to single phase equipment only.

Tesla Guidelines: Powerwall+ and Powerwall 3, and Tesla String Inverters follow strict installation guidelines and milestone submissions. Follow manufacturers installation instructions carefully to avoid rejections and service visits.

[C] Foreign Entities of Concern

Click to View FEOC Details

[Feoc A] Overview

The One Big Beautiful Bill Act (OBBBA) enacted the 2026 Foreign Entity of Concern (FEOC) provision which attempts to reduce reliance on supply chains tied to covered foreign nations (China, Russia, North Korea, Iran). Starting on January 1st, 2026, solar and energy storage projects must meet new sourcing thresholds or lose the ITC value. From January 1st 2026, this means that FEOC-compliant installs are required across all Palmetto installations, and many panel manufacturers owned by or tied to Foreign Entities of Concern will be removed from our AVL.

It's important to understand that FEOC is a distinct concept, but does dot lines to other installation concepts. See below for additional detail.

FEOC Focus

FEOC Compliance focuses on who owns and controls the companies in a supply chain. This is distinct from Domestic Content, which focuses on where equipment is manufactured. While the concepts have some practical overlap, they are distinct.

Put plainly: FEOC provisions aim to move installations away from Chinese-owned or tied equipment manufacturers. Domestic Content compliance does not equal FEOC compliance.

FEOC Goal

Starting in 2026, certain % of project value cannot be tied to Foreign Entity of Concerned (for practical purposes of residential solar equipment, this is focused on China).

This means that all installations must be FEOC compliant starting on January 1, 2026 (defined by “Install Submitted” date). Put plainly: At least 40% for PV and 55% for Battery of installed equipment cannot come from a Foreign Entity of Concern. Palmetto will execute calculations for our partners (in-portal calculator coming soon).

Minimum Thresholds

2026: 40% PV Only | 55% PV + Battery or Battery Only

2027: 45% PV Only | 60% PV + Battery or Battery Only

(Percentages increase by 5% each year thereafter)

PV and Battery FEOC percentages are calculated separately via the Domestic Content table from IRS Notice 2025-08

Put plainly: in 2026, at least 40% for PV and 55% for Battery cannot be tied to a Foreign Entity of Concern."

How FEOC Works

Palmetto works directly with OEMs (manufacturers) and distributors on a robust set of qualifying paperwork and analysis. Each piece of equipment then goes through a deep diligence process with our tax partner, Deloitte. This process is robust and time consuming, requiring patience and diligence by all parties involved.

Based on federal guidelines, each piece of equipment used in solar installations is assigned a unique percentage, based on the entity which owns the manufacturing process.

That total percentage must meet the minimum threshold. Calculations are already curated for our partners. Partners will note that calculations rely on the current Domestic Content tables-- but substitute the who (FEOC) for the where (ITC-DC). Put plainly: there is overlap in the underlying calculations for determining both FEOC and Domestic Content eligibility, but this does not mean that the two are synonymous.

FEOC Example

An installation using an MLPE Inverter (SE, Enphase, QCell).

40% FEOC Compliance can be achieved via:

[Option A]

  • Full FEOC-Compliant Racking (19.6%)

  • FEOC-Compliant Inverter (24.8%)

  • Any AVL-approved panel (in 2026, all AVL panels will be FEOC-compliant).

[Option B]

  • Full FEOC-Compliant Racking (24.5%)

  • FEOC-Compliant Inverter (3.4%)

  • AVL-approved panel with at least 12.1% non-FEOC content (details on specific qualifying panel SKUs to come)"

For practical purposes, Palmetto will not have any non-FEOC-compliant panels on our AVL.

Latest Update to this Article

12/12/25

Next Est. FEOC Update

12/15/25

Partners are advised to begin navigating away from large purchases of Chinese-owned modules such as Trina, Jinko, JA, Longi, and Canadian Solar.

Projects with these 2025 modules must have M1 install packages submitted by 12/31/25 to qualify.

[FEOC B] Key Things to Know

Current Challenges and Uncertainties

  1. Political Shifts: FEOC and Domestic Content policies will likely evolve significantly over the next 6–12 months.

  2. OEM Transparency: Limited information from manufacturers at the moment makes it difficult to verify compliance today. We are working with manufacturers to compile information and certifications.

  3. FEOC Calculations: Determined by PFE (Prohibited Foreign Entity) ownership and supply chain involvement, not just manufacturing location. Importantly, Domestic Content compliance does not guarantee FEOC compliance.

Ongoing Initiatives

  • Portal FEOC Calculator: A new tool is in development to simplify compliance verification.

  • Supply Agreements: We are in the process of securing FEOC-compliant panel supply (including REC, QCells, Silfab, Hyundai, Sirius PV, and others) for all LightReach installs. More to come soon on allocation process of these materials.

  • Safe Harbor: We have already executed a significant safe harbor of materials, and execution of additional safe harbors is in progress to ensure supply security. See section D for more details.

Guidance for Partners

  1. Communication: Keep open communication with Regional Managers, Distributors, and OEMs. Confirm hardware selections with RMs and update forecasts regularly.

  2. Supply Chain Prep: Favor proven, non-FEOC entities (REC, QCells, Silfab, Hyundai, Sirius PV). Avoid major long-term hardware commitments until policy clarity improves.

  3. Monitor Palmetto LightReach: Expect updates (news.golightreach.com and this article) as things evolve. We are securing panel supply for our EPCs in a number of different ways, including via Supply Agreements and Safe Harboring.

[FEOC C] Equipment Details

We recommend the following paths for hardware selection going into 2026. Note that guidance will evolve.

[D] Domestic Content

Click to View Domestic Content Details

[ITC-DC A] Overview

The Inflation Reduction Act of 2022 boosts residential solar projects with an additional ITC value for using U.S.-made materials.

LightReach offers the option to enroll in the Domestic Content (ITC-DC) program, and receive a higher EPC price per watt as a result. This process is optional for qualified installers and requires specific eligibility criteria (details below) to be met. It is important to note that the DC Eligible Equipment is subject to change and requires careful planning + strict adherence.

To be eligible for domestic content pricing, the equipment selected on the install must meet 45% domestic content value.

[ITC-DC B] Installer Enrollment

Who Can Enroll?

All partners are eligible to submit, subject to the below.

What's Required for Enrollment?

1) Example BOM (Bill of Materials) that Installer intends to use

2) Sales Forecast

3) Addendum Signature

Installer Expectations

1) Installer must be in good standing with LightReach, including install approval rates and compliance.

2) LightReach will review requests in the order in which they were received. This process may take a few days. Partners should review status updates on their ticket.

3) Out of fairness to all partners on the platform, LightReach support cannot expedite enrollment requests.

4) Exact ITC-DC pricing values are confidential to installer leadership. PLR will share additional ITC value with installers in the form of a higher EPC payment. Exact values are generally standardized by tier.

How to Enroll

Via Support Center Chat. Click for Visual.

Authorized organization personnel can chat in via support chat, selecting the "Installer: Organization Settings" queue, "G) Domestic Content Settings," & the "Domestic Content: Enrollment" selection when prompted.

[ITC-DC C] Quoting and Pricing

All sales will follow typical M0 Guidelines to receive NTP.

After successfully enrolling, distinct domestic content pricing will appear in the quoting tool when creating a quote. Once the quote has been created for a project, it will resemble the image below in the quoting tab: To verify whether a project qualifies for Domestic Content pricing:

  1. Navigate to the quote section under the account in the LightReach portal (located below the Underwriting/Credit App section).

  2. Check pricing details:

    • If you see a "DC Boost", this indicates domestic content pricing is enabled for that account and project.

    • If there is only one price visible (without the "DC Boost"), this means the project does not qualify for DC-related benefits.

Successfully install with Domestic Content? Installer will receive payment based on the "DC Boost" price.

Install without Domestic Content? Installer will receive payment based on the "Non-DC price", aka standard, default pricing. There is no bespoke 'penalty' for installing non-DC; rather, the installer would simply not receive the higher, boosted amount.

[ITC-DC E] Milestone Submissions

Organization “enrollment” for Domestic Content is for 100% of projects. However, an EPC will confirm at the Install Milestone submission on an individual account level if domestic content was used.

Organizations will complete an Attestation at M1 submission, where the org must indicate whether the installation used Domestic Content or not.

  • Yes, ITC-DC was used = Install will be reviewed for ITC-DC requirements

  • No, ITC-DC was not used = Install will be reviewed as a standard review + pricing will adjust back to standard "Non-DC price" amounts.

How it Works in the Portal: Click to Expand for Visuals

Projects that are eligible for Domestic Content will have a slightly different Install Package Submission flow

  • Partners are required to confirm System Design & Domestic Content Qualification prior to full package submission

  • Partners can "Update Design" from Install Package, requires going back to DC System Design page and re-calculating

Outside of the standard M1 Submission Package Deliverables and Photosets required at the M1 Installation Milestone, organizations will need to provide additional documentation that a submitted install has qualified for Domestic Content pricing and benefits.

[ITC-DC F] FAQ

1

Is Domestic Content Mandatory?

No, the program is optional

2

My Org is enabled with Direct pay, can we participate in Domestic Content?

Yes

3

How do I Enroll?

Please refer to Section B for more information on how to enroll.

4

If I'm enrolled, but my team sells in an external sales portal, how do I view ITC-DC values?

External sales portals, such as Solo, will display the ITC-DC values (higher values).

Both ITC-DC and standard values are visible in the LightReach portal for convenience.

5

How can I calculate whether my project is eligible for Domestic Content?

Use the in-portal calculator to help guide eligible combinations.

The DC calculator is the source of truth for specific SKUs that qualify

6

Will Domestic Content projects receive conditional approvals?

Domestic Content projects will NOT be conditionally approved at install. Partners will need to either provide sufficient proof OR “opt out” of Domestic Content for the project to proceed with the non-DC boost pricing.

7

What % do I need to achieve to have a project qualify for ITC-DC?

As of the latest federal update in June 2025, a 45% domestic content value threshold is required to be met, but installers should bear in mind that this threshold will increase by 5% each year, meaning that on January 1st 2026, the threshold will be 50%.

8

Will Storage selection provide an additional boost on ITC-DC pricing?

PV provides an avenue ITC-DC boost.

PV + Storage provides an avenue to a larger ITC-DC boost.

Storage-Only does not provide an avenue for a boost.

9

Can I use multiple hardware manufacturers/OEMs?

No, mounting hardware with multiple OEMs (Original Equipment Manufacturers) is not permitted.

All racking components used on any given site must be from the same manufacturer.

Case by case flexibility may be provided in the case of Module-Mount MLPE fasteners from other OEMs are necessary. Please contact your relationship manager in advance for potential options.

10

Qualifying for Domestic Content on Mounting Hardware?

To qualify for ITC-DC on mounting hardware, you need:

  • Domestic Rail = Domestic Rail + Domestic Splice

  • Domestic Fasteners = Domestic MLPE Fastener + Domestic Clamps (Mid AND End) + Domestic Splice

[E] Safe Harbor

Click to View Safe Harbor Details

[Safe Harbor A] Overview

Safe Harboring is a process whereby Palmetto purchases large orders of equipment in advance, to be allocated to our EPC partners. This serves to

  • [1] Effectively extend the 30% TPO tax credit value into 2030, allowing us to maintain competitive pricing

  • [2] Ensure FEOC Compliance and

  • [3] Generally mitigate against equipment shortages in the near term.

Palmetto has already executed, and will continue to execute on, our Safe Harbor strategy to support both FEOC compliance and Domestic Content optionality.

Who can Safe Harbor for TPO products?

Palmetto LightReach. Individual installers cannot Safe Harbor directly for LightReach sales, due to fine print complexities. For the avoidance of doubt, there are no workarounds to this.

How does Palmetto Safe Harbor?

We work directly with OEMs (manufacturers) and Distributors, along with our tax partner, Deloitte.

What is Palmetto's strategy geared toward?

We are primarily focused on the front of preserving the ITC value, thereby maintaining our competitive pricing.

Palmetto is planning some smaller, shorter-term Safe Harbor purchases for non-FEOC-compliant equipment; however, quantities and scope will be limited.

For the avoidance of doubt, if you have not already directly worked with Palmetto leadership on a specific shorter term safe harbor, we will not be able to make any other special accommodations.

How will Palmetto's Safe Harbored equipment be allocated?

Formal process to be announced.

Direct Pay will remain optional, and pricing will not be expressly directed by Palmetto (IE partners will have flexibility to use their existing distributor SPAs as desired).

How much equipment will be available?

Via Safe Harbor and Supply Agreements, we will be able to support FEOC compliance for all sales as forecast with you, our partners. This will ensure that all partners have FEOC-compliant equipment in 2026.

However, it should be noted that Domestic Content panels are likely to be in shorter supply, especially in Q1 2026.
