 Exhibit 10.43 

VIVINT SOLAR, INC. 

SUBSCRIPTION AGREEMENT 

September 3, 2014 
 THIS
SUBSCRIPTION AGREEMENT (this “Agreement”) by and among VIVINT SOLAR, INC., a Delaware corporation (“Solar”), and each of the investors who have signed a counterpart signature page to this Agreement (individually a
“Purchaser” and collectively, the “Purchasers”) is made as of the date set forth above. 
 WHEREAS, Solar
desires an infusion of an aggregate of approximately $75 million of additional common equity capital into Solar based on a total pre-money equity valuation of $828.5 million; and 

WHEREAS, Purchasers are willing to invest such amount in Solar common equity capital; and 

WHEREAS, on the terms and subject to the conditions hereof, each of the Purchasers desires to subscribe for and acquire from Solar, and Solar
desires to issue and sell to each of the Purchasers, shares of Solar common stock, par value $0.01 per share of Solar (“Solar Common Stock”) based on such valuation; 

NOW, THEREFORE, in order to implement the foregoing and in consideration of the mutual representations, warranties, covenants and agreements
contained herein, the parties hereto agree as follows: 
 1. Sale and Purchase of Subscription Securities. At the Closing (as defined
below), upon the terms and subject to the conditions of this Agreement, each Purchaser agrees, severally and not jointly, to purchase, and Solar agrees to sell and issue to each Purchaser, the number of shares of Solar Common Stock set forth in the
space designated “Number of Shares” on such Purchaser’s counterpart signature page to this Agreement, at a cash purchase price of $10.666667 per share (the “Subscription Amount”). Solar’s agreement with each
Purchaser is a separate agreement, and the sale and issuance of the Solar Common Stock to each Purchaser is a separate sale and issuance to such Purchaser. The shares of Solar Common Stock purchased by the Purchasers hereunder (including any
additional shares subsequently issued pursuant to the adjustment mechanism described in Section 1(c) below) are referred to as the “Subscription Securities”. 

(b) Subject to the satisfaction (or waiver by the parties entitled to the benefit thereof) of the conditions set forth in
Section 2 of this Agreement, the closing of the transactions contemplated hereby (the “Closing”) will take place at such time, date and location as the parties may mutually agree. At the Closing, Solar will duly record
in its stockholder registry in the name of each of the Purchasers the applicable number of Subscription Securities, against the transfer, contribution and payment to Solar of the aggregate Subscription Amount related thereto, which shall represent
payment in full for the Subscription Securities. 
 (c) From the date hereof until the earlier of (i) the initial public offering of
Solar and (ii) the first anniversary of the Closing Date, in the event that Solar issues or sells any 

  
 1 








 Solar Common Stock or any other securities of Solar or its subsidiaries that would entitle the holder thereof to
acquire at any time Solar Common Stock (“Solar Common Stock Equivalent”) in one or more transactions to an unrelated third party, if such Solar Common Stock or Solar Common Stock Equivalent is sold at or otherwise reflects a Solar
Common Stock valuation per share of less than $10.666667, then, as an adjustment in the purchase price per share for the Subscription Securities purchased by the Purchasers, Solar shall issue to each of the Purchasers or their respective
transferees, as applicable, such number of additional shares of Solar Common Stock as would reflect, as of the Closing Date, the valuation per share of Solar Common Stock implied by such subsequent issuance. Such adjustment and issuance to the
Purchasers of additional shares will occur serially in the event additional such issuances to a third party subsequently occur at an even lower valuation. The parties expect that the negotiations with respect to any such subsequent issuance would
take into account the adjustment mechanism of this Section 1(c). In no event shall any of the Subscription Securities issued pursuant hereto and the related right to receive additional shares of Solar Common Stock as contemplated by this
Section 1(c) be separable. 
 2. Conditions to Sale and Purchase of Subscription Securities. 

(a) Notwithstanding anything in this Agreement to the contrary, none of the Purchasers will be under any obligation to purchase or subscribe
for any Subscription Securities unless (i) the representations and warranties of Solar contained in Section 3 hereof are true and correct in all material respects as of the Closing and (ii) Solar is not in breach of any
agreement, obligation or covenant herein required to be performed or observed by Solar on or prior to the Closing. 
 (b) Notwithstanding
anything in this Agreement to the contrary, Solar shall be under no obligation to issue, sell or grant to any Purchaser any Subscription Securities unless (i) the representations and warranties of such Purchaser contained in
Section 4 hereof are true and correct in all material respects as of the Closing and (ii) such Purchaser is not in breach of any agreement, obligation or covenant herein required to be performed or observed by such Purchaser on or
prior to the Closing. 
 3. Representations and Warranties of Solar. Solar represents and warrants to each of the Purchasers as
follows: 
 (a) Solar is a corporation duly organized, validly existing and in good standing under the laws of the state of Delaware and has
all requisite power and authority to execute and deliver this Agreement and to perform its obligations hereunder; the execution and delivery by Solar of this Agreement, the performance by Solar of its obligations hereunder, and the consummation by
Solar of the transactions contemplated hereby have been duly authorized by all requisite action on the part of Solar; this Agreement has been duly executed and delivered by Solar and, assuming the due authorization, execution and delivery hereof by
the Purchasers, constitutes a legal, valid and binding obligation of Solar, enforceable against Solar in accordance with its terms, except as enforceability may be limited by bankruptcy, insolvency, reorganization, moratorium and other similar laws
relating to or affecting creditors’ rights generally or by general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law); 







 (b) the Subscription Securities, when issued and delivered in accordance with the terms hereof,
will be duly authorized, validly issued, fully paid and nonassessable, and free and clear of any liens or encumbrances of any kind other than under applicable securities laws or as set forth in the by-laws of Solar; 

(c) the execution, delivery and performance by Solar of this Agreement and the consummation by Solar of the transactions contemplated hereby

legal, valid and binding obligation of Solar or (ii) to authorize or permit the consummation by Solar of the issuance of the Subscription Securities; 

(e) As of the date hereof, without taking into effect the issuance of the Subscription Securities, the authorized capital stock of Solar
consists of 100,000,000 shares of Solar Common Stock, of which 77,671,875 shares of Solar Common Stock were issued and outstanding; and 

(f) Solar has not employed any broker or finder in connection with the transactions contemplated by this Agreement to whom any Purchaser might
have any obligation. 
 4. Representations and Warranties of the Purchasers. 

(a) Each Purchaser that is other than a natural person hereby represents and warrants to Solar that: 

(i) Such Purchaser is a corporation, limited liability company, partnership, limited partnership or other entity or trust duly organized and
validly existing and in good standing under the laws of the state of its organization or formation and has all requisite power and authority to execute and deliver this Agreement and to perform its obligations hereunder; and 

(ii) the execution and delivery by such Purchaser of this Agreement, the performance by such Purchaser of its obligations hereunder and the
consummation by such Purchaser of the transactions contemplated hereby (A) have been duly authorized by all requisite action on the part of such Purchaser and (B) do not and will not, with or without the giving of notice or the passage of
time or both, violate the provisions of the articles or certificate of incorporation, by-laws, certificate or articles of formation or organization, operating agreement or limited liability company agreement, partnership agreement or comparable
documents, agreements or instruments of such Purchaser, in each case as amended to date. 







 (b) Each Purchaser hereby, severally as to itself or himself, and not jointly or as to any other
Purchaser, represents and warrants to Solar that: 
 (i) this Agreement has been duly executed and delivered by such Purchaser and, assuming
the due authorization, execution and delivery thereof by Solar, constitutes a legal, valid and binding obligation of such Purchaser, enforceable against such Purchaser in accordance with its terms, except as enforceability may be limited by
bankruptcy, insolvency, reorganization, moratorium and other similar laws relating to or affecting creditors’ rights generally or by general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity
or at law); 
 (ii) the execution, delivery and performance by such Purchaser of this Agreement and the consummation by such Purchaser of
the transactions contemplated hereby do not and will not, with or without the giving of notice or the passage of time or both, (i) violate the provisions of any law, rule or regulation applicable to such Purchaser or its properties or assets;
or (ii) violate any judgment, decree, order or award of any court, governmental or quasi-governmental agency or arbitrator applicable to such Purchaser or its properties or assets; 

(iii) no consent, approval, exemption or authorization is required to be obtained from, no notice is required to be given to, and no filing is
required to be obtained from, any third party (including, without limitation, governmental and quasi-governmental agencies, authorities and instrumentalities of competent jurisdiction) by such Purchaser, in order (i) for this Agreement to
constitute a legal, valid and binding obligation of such Purchaser or (ii) to authorize or permit the consummation by such Purchaser of its purchase of the Subscription Securities; 

(iv) such Purchaser (i) is an “accredited investor” within the definition of Regulation D promulgated under the Securities Act
of 1933, as amended, and the rules and regulations promulgated thereunder (the “Securities Act”), (ii) is experienced in evaluating and investing in private placement transactions of securities of similar companies and
acknowledges that it is able to fend for itself, can bear the economic risk of such Purchaser’s investment in Solar, and has such knowledge and experience in financial and business matters that such Purchaser is capable of evaluating the merits
and risks of the investment in the Subscription Securities and can afford a complete loss of its investment, (iii) has not been organized for the purpose of acquiring the Subscription Securities, (iv) understands that no public market now
exists for the Subscription Securities and that it is likely that no public market will ever exist for the Subscription Securities, (v) understands that the Subscription Securities may not be sold, transferred, or otherwise disposed of without
registration under the Securities Act or an exemption therefrom, and that, in the absence of an effective registration statement covering the Subscription Securities or an available exemption from registration under the Securities Act, the
Subscription Securities must be held indefinitely, (vi) understands that the exemption from registration afforded by Rule 144 (the provisions of which are known to it) promulgated under the Securities Act depends on the satisfaction of various
conditions, and that, if applicable, Rule 144 may afford the basis for sales only in limited amounts; (vii) understands that the Subscription Securities will be subject to the provisions of the by-laws of Solar, which provides for certain
restrictions on the transferability of the Subscription Securities, (viii) understands that a notation may be made in the appropriate records of Solar indicating that the Subscription 







 
Securities are subject to restrictions on transfer and, if Solar should at some time in the future engage the services of a securities transfer agent, appropriate stop-transfer instructions will
be issued to such transfer agent with respect to the Subscription Securities, and (ix) understands that its investment in the Subscription Securities involves a significant degree of risk including a risk of total loss of its investment, and it
is fully aware of and understands all the risk factors related to its purchase of the Subscription Securities; 
 (v) such Purchaser has
been advised by Solar that a restrictive legend in the form set forth below shall be placed on the certificates representing the Solar Common Stock, if any: 

“NO TRANSFER, SALE, ASSIGNMENT, PLEDGE, HYPOTHECATION OR OTHER DISPOSITION OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE MAY BE MADE
EXCEPT (A) PURSUANT TO A REGISTRATION STATEMENT EFFECTIVE UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR (B) PURSUANT TO AN EXEMPTION FROM REGISTRATION THEREUNDER.” 

(vi) such Purchaser is acquiring the Subscription Securities for its own account, solely for the purpose of investment and not with a view to,
or for sale in connection with, any distribution thereof in violation of federal law or any applicable securities law. Such Purchaser understands that the Subscription Securities have not been registered under the Securities Act on the basis that
the sale provided for in this Agreement is exempt from the registration provisions thereof; 
 (vii) to the full satisfaction of such
Purchaser, such Purchaser has been furnished any materials it has requested relating to Solar and the Subscription Securities, and such Purchaser has been afforded the opportunity to ask questions of representatives of Solar concerning Solar and the
Subscription Securities and to obtain any additional information necessary to verify the accuracy of any information provided to it; 

(viii) such Purchaser is not relying upon any information, representation or warranty by Solar or any affiliate or agent of Solar in
determining to invest in Solar, and expressly acknowledges that neither Solar or any affiliate or agent of Solar has made any representations or warranties to it in connection therewith other than the representations and warranties made by Solar in
this Agreement. Such Purchaser has, independently and without reliance upon Solar or any affiliate or agent of Solar, and based on such documents and information as such Purchaser has deemed appropriate, made its own appraisal of and investigation
into the business, operations, property, financial and other condition and creditworthiness of Solar and made its own investment decision with respect to the investment represented by the Subscription Securities. Such Purchaser has consulted to the
extent deemed appropriate by such Purchaser with such Purchaser’s own advisers as to the financial, tax, legal and related matters concerning an investment in the Subscription Securities and on that basis understands the financial, legal, tax
and related consequences of an investment in the Subscription Securities, and believes that an investment in the Subscription Securities is suitable and appropriate for such Purchaser; 







 (ix) such Purchaser has not employed any broker or finder in connection with the transactions
contemplated by this Agreement; and 
 (x) such Purchaser has received a copy of the form of registration rights agreement attached to the
Registration Statement on Form S-1 filed by Solar with the U.S. Securities Exchange Commission on August 26, 2014 as Exhibit 4.2 and agrees to be bound by the terms and provisions thereof, as if the same has been duly executed by the
undersigned, subject to such modifications thereto as may be agreed to by the authorized persons of Solar and Purchasers. 
 5.
Miscellaneous. 
 (a) Termination. This Agreement shall be terminated by mutual written consent of Solar and Purchasers, provided
that this Agreement may be terminated in the case of any Purchaser solely as to such Purchaser and not as to any other Purchaser by a written consent of Solar and such Purchaser, and further provided that any such termination by or affecting any
specific Purchaser shall have no effect on the validity and enforceability of this Agreement as between Solar and any other Purchaser. 

(b) Amendment; Waiver. This Agreement may be amended only by a written instrument signed by the parties hereto against whom such
amendment or waiver is sought to be enforced. No waiver by any party hereto of any of the provisions hereof shall be effective unless set forth in a writing executed by the party so waiving.
