This page provides guidance for American Recovery and Reinvestment Act projects required to follow the Buy American Provision. The Provision requires that a project use U.S.-produced iron, steel, and manufactured goods unless for one of three exceptions applies (non-availability, unreasonable cost, and inconsistent with the public interest).

Project Specific Non-Availability Waivers

Public Interest Waivers

Date Item Description
December 6, 2011
Waiver for Donated items
Donated means manufactured goods provided to the project at zero cost. These goods must not hold a caveat, expectation, or quid-pro-quo of any sort, nor may their donation bind the grant recipient in any way. The recipient, for example, may not agree to pay more for one item, so as to have another item donated, nor may they promise more business in the future in exchange for a donated item. The project officer or the contracting officer will be consulted to determine whether the goods qualify as donated; this will serve to prevent abuse of this waiver. This waiver applies only to the donated manufactured goods themselves. All funds used in the project are still subject to the Buy American requirements and other contract requirements. Use of this Waiver requires approval of project and contracting officers.
Guidance will be released January 2012.

Solar Public Interest Waiver

Public Interest Waiver for Solar Projects


  1. Domestically manufactured modules containing foreign-manufactured cells.
  2. Foreign-manufactured modules, when comprised completely of domestically manufactured cells.
  3. Any ancillary items and equipment (including, but not limited to, charge controllers, combiners and disconnect boxes, breakers and fuses, racks, trackers, lugs, wires, cables and all otherwise incidental equipment with the exception of inverters and batteries) when utilized in a solar installation involving a U.S. manufactured PV module, or a module manufactured abroad but comprised exclusively of domestically-manufactured cells.

The new waiver, issued August 1, 2011 This determination replaces and supersedes the Solar Public Interest Waiver issued August 6, 2010, amended September 30, 2010 and extended February 4, 2011. Although the waiver extension issued February 4, 2011 was slated to be a one-time extension coinciding with the ramp-down of EERE Recovery Act-funded projects, EERE has determined that enough projects remain active to justify a new Public Interest waiver determination. This determination does not have an expiration date, and is valid until such time as the Assistant Secretary chooses to modify or revoke the waiver. The Assistant Secretary reserves the right to revisit and amend this determination based on new information or new developments.
