Explanatory Note

This Amendment No. 1 to the Registration Statement on Form S-1 (No. 333-251035) is being filed solely to include Exhibit 5.1, as reflected in the Exhibit Index. No change has been made to the preliminary prospectus constituting Part I of this Registration Statement. Accordingly, Part I has been omitted from this filing.

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

The following table sets forth all expenses to be paid by the registrant, other than estimated underwriting discounts and commissions, in connection with this offering. All expenses will be borne by the registrant. All amounts shown are estimates except for the SEC registration fee, and the FINRA filing fee.

We are incorporated under the laws of the State of Delaware and are subject to the DGCL. Section 145 of the DGCL authorizes a corporation’s Board of Directors to grant, and authorizes a court to award, indemnity to officers, directors and other corporate agents. As permitted by Section 102(b)(7) of the DGCL, the registrant’s certificate of incorporation includes provisions that eliminate the personal liability of its directors and officers for monetary damages for breach of their fiduciary duty as directors and officers, except for liability (i) for any breach of the director’s duty of loyalty to the corporation or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) for unlawful payments of dividends or unlawful stock repurchases, redemptions or other distributions or (iv) for any transaction from which the director derived an improper personal benefit.

In addition, as permitted by Section 145 of the DGCL, the bylaws of the registrant provide that:

II-1

The registrant also maintains directors’ and officers’ insurance to insure such persons against certain liabilities.

We have entered into separate indemnification agreements with our directors and officers. Each indemnification agreement provides, among other things, for indemnification to the fullest extent permitted by law and our Certificate of Incorporation and Bylaws against any and all expenses, judgments, fines, penalties and amounts paid in settlement of any claim. The indemnification agreements provide for the advancement or payment of all expenses to the indemnitee and for reimbursement to us if it is found that such indemnitee is not entitled to such indemnification under applicable law and our Certificate of Incorporation and Bylaws.

These indemnification provisions may be sufficiently broad to permit indemnification of the registrant’s officers and directors for liabilities (including reimbursement of expenses incurred) arising under the Securities Act.

The underwriting agreement filed as Exhibit 1.1 to this registration statement on Form S-1 provides for indemnification by the underwriters of the registrant and its officers and directors for certain liabilities arising under the Securities Act and otherwise.

During the last three years, the registrant has issued securities in the following transactions, each of which was exempt from the registration requirements of the Securities Act. No underwriters were involved in any of the below-referenced sales of securities. The historical share data set forth in this section has not been adjusted to reflect the Stock Split that is expected to be effected prior to the completion of this offering:

See the Exhibit Index immediately following the signature page hereto, which is incorporated by reference as if fully set forth herein.

The undersigned registrant hereby undertakes to provide to the underwriters at the closing specified in the underwriting agreement certificates in such denominations and registered in such names as required by the underwriters to permit prompt delivery to each purchaser.

II-2

Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

The undersigned registrant hereby undertakes that:

Ladies and Gentlemen:

We are acting as special counsel to Array Technologies, Inc. (the “Company”), a Delaware corporation, in connection with the preparation and filing of a Registration Statement on Form S-1, originally filed with the Securities and Exchange Commission (the “Commission”) on November 30, 2020, under the Securities Act of 1933, as amended (the “Act”) (such Registration Statement, as amended or supplemented and including the exhibits thereto, is hereinafter referred to as the “Registration Statement”), relating to the proposed registration by the Company of 25,000,000 shares of common stock, par value $0.001 per share, of the Company (“Common Stock”) to be sold by the selling stockholder identified in the Registration Statement (the “Firm Shares”) and up to 3,750,000 additional shares of Common Stock to be sold by such selling stockholder to cover the underwriters’ option to purchase additional shares, if any (the “Option Shares” and, together with the Firm Shares, the “Shares”). The offering of the Shares is referred to herein as the “Offering.”

In that connection, we have examined originals, or copies certified or otherwise identified to our satisfaction, of such documents, corporate records and other instruments as we have deemed necessary for the purposes of this opinion, including (i) the Amended and Restated Certificate of Incorporation of the Company, dated October 19, 2020 (the “Charter”); (ii) the Amended and Restated Bylaws of the Company, as currently in effect (the “Bylaws”); (iii) the Underwriting Agreement in the form filed as Exhibit 1.1 to the Registration Statement (the “Underwriting Agreement”); (iv) resolutions of the board of directors of the Company; and (v) the Registration Statement.

For purposes of this opinion, we have assumed the authenticity of all documents submitted to us as originals, the conformity to the originals of all documents submitted to us as copies and the authenticity of the originals of all documents submitted to us as copies. We have also assumed the legal capacity of all natural persons, the genuineness of the signatures of persons signing all documents in connection with which this opinion is rendered, the authority of such persons signing on behalf of the parties thereto and the due authorization, execution and delivery of all documents by the parties thereto other than the Company. We have not independently established or verified any facts relevant to the opinion expressed herein, but have relied upon statements and representations of officers and other representatives of the Company and others as to factual matters.

Based upon and subject to the foregoing qualifications, assumptions and limitations and the further limitations set forth below, we are of the opinion that, upon (i) the due execution and delivery of the Underwriting Agreement by the parties thereto and (ii) the effectiveness of the Registration Statement under the Act, the Shares (including any Option Shares) will have been duly authorized and will be validly issued, fully paid and non-assessable.

Our opinions expressed above are subject to the qualifications that we express no opinion as to the applicability of, compliance with, or effect of any laws except the General Corporation Law of the State of Delaware.

We hereby consent to the filing of this opinion with the Commission as Exhibit 5.1 to the Registration Statement. We also consent to the reference to our firm under the heading “Legal Matters” in the Registration Statement. In giving this consent, we do not thereby admit that we are in the category of persons whose consent is required under Section 7 of the Act or the rules and regulations of the Commission.

We do not find it necessary for the purposes of this opinion, and accordingly we do not purport to cover herein, the application of the securities or “Blue Sky” laws of the various states to the Offering.

This opinion is limited to the specific issues addressed herein, and no opinion may be inferred or implied beyond that expressly stated herein. We assume no obligation to revise or supplement this opinion should the General Corporation Law of the State of Delaware be changed by legislative action, judicial decision or otherwise.

This opinion is furnished to you in connection with the filing of the Registration Statement.
