Key Terms

6 terms
safe harbor regulatory
"today announced a new safe harbor agreement with a U.S. solar"
Safe harbor is a rule that protects companies or individuals from legal trouble if they follow certain guidelines or procedures. It’s like having a safety net that allows them to act without fear of punishment, as long as they stick to the rules. This helps encourage honest behavior and clear standards in financial and legal activities.
third-party ownership (tpo) financial
"company that offers third-party ownership (TPO) agreements to homeowners"
Third-party ownership is an arrangement where an outside entity—not the company or the original owner—holds legal rights to an asset, contract, or revenue stream tied to the company. For investors, it matters because that outside ownership can change who collects income, who bears losses, and how transparent and controllable the asset is; think of it like a car you use every day that someone else legally owns, which limits what you can do with it and who benefits from it.
power purchase agreements (ppas) financial
"including leases and power purchase agreements (PPAs)."
Power purchase agreements (PPAs) are long-term contracts in which a buyer agrees to purchase electricity directly from a specific generator at agreed prices and terms. Like a multi-year subscription for power, PPAs give the seller predictable revenue and the buyer price certainty, which makes energy projects easier to finance and reduces revenue volatility — key factors investors use to assess risk and value.
investment tax credit (itc) regulatory
"preserve eligibility for the base investment tax credit (ITC) and"
An investment tax credit (ITC) is a government incentive that reduces a company’s tax bill by a set percentage of money spent on qualifying capital projects, like equipment or clean energy installations. Think of it as a coupon that cuts taxes dollar-for-dollar for certain investments; it matters to investors because it improves a project’s cash flow and return on investment, can change project economics and valuation, and may influence capital allocation decisions.
domestic content bonus credit regulatory
"the base investment tax credit (ITC) and the domestic content bonus credit."
A domestic content bonus credit is a government financial incentive that rewards companies for using locally sourced materials, parts, or labor in a project by reducing their taxes or offering a cash-like credit. Think of it as a store coupon a business earns for buying locally: it lowers the project’s net cost and can improve profit margins, make bids more competitive, and change the economics or timeline of investments—factors investors use to value a company.
physical work test (pwt) regulatory
"Enphase’s total physical work test (PWT) order backlog with TPO providers"
A physical work test (PWT) is an assessment that measures a person's ability to perform manual or physically demanding job tasks, such as lifting, carrying, standing, or climbing. For investors, PWTs matter because their results influence workforce availability, insurance and disability costs, and legal or regulatory liabilities—similar to a fitness-for-duty check that can affect a company’s labor expenses, productivity, and potential compensation claims.

FREMONT, Calif., May 07, 2026 (GLOBE NEWSWIRE) --  Enphase Energy, Inc. (NASDAQ: ENPH), a global energy technology company, today announced a new safe harbor agreement with a U.S. solar and battery financing company that offers third-party ownership (TPO) agreements to homeowners and businesses, including leases and power purchase agreements (PPAs).

The new agreement was signed on April 28, 2026, and is expected to generate approximately $52 million in revenue. It covers Enphase® IQ9™ Microinverters for both residential and commercial solar projects, with products supplied from manufacturing facilities in the United States.

With this agreement, Enphase’s total physical work test (PWT) order backlog with TPO providers is now approximately $873.7 million. This total includes approximately $67.7 million signed in the fourth quarter of 2025, approximately $754 million signed earlier in 2026, and the approximately $52 million signed on April 28, 2026. Enphase expects revenue associated with this PWT backlog to be recognized between 2027 to 2030, subject to customer project timing, demand, and other factors.

This PWT backlog covers IQ9 Microinverters only. Cables, accessories, and IQ® Batteries represent additional revenue opportunities that may be attached to these microinverter systems over the same 2027 to 2030 period.

Safe harboring can help future projects preserve eligibility for the base investment tax credit (ITC) and the domestic content bonus credit. By safe harboring equipment now, solar companies can help reduce uncertainty around future project economics and support long-term deployment planning.

“This additional safe harbor agreement reflects the continued momentum we are seeing with TPO providers as they plan for future residential and commercial solar projects,” said Ken Fong, senior vice president of sales at Enphase Energy. “Our IQ9 Microinverters, supplied from U.S. manufacturing facilities, give our partners a high-quality solution as they prepare for deployments under evolving tax credit rules.”

Project developers should consult their own legal and tax advisors to confirm eligibility for available tax credits. To learn more about Enphase products and services, please visit the website.
