Exhibit 10.10

INVESTMENT AGREEMENT

THIS INVESTMENT AGREEMENT (this “Agreement”), dated [●], 2021, is by and among (i) SDCL EDGE Acquisition Corporation, a Cayman Islands exempted company (the “SPAC”), (ii) SDCL EDGE Sponsor LLC, a Cayman Islands limited liability company (the “Sponsor”), and (iii) [●] (the “Investor”).

WHEREAS, in connection with the initial public offering (the “IPO”) of units (the “Public Units”) of the SPAC, the Investor has expressed an interest in acquiring up to 2,000,000 Public Units in the IPO, each comprising one share of the Issuer’s Class A ordinary shares, par value $0.0001 per share (the “Class A Ordinary Shares”), and one-half of a redeemable warrant (each, a “Warrant”), where each whole Warrant is initially exercisable for one Class A Ordinary Share at an exercise price of $11.50 per Class A Ordinary Share, at a price of $10.00 per unit (altogether, the “IPO Indication”).

WHEREAS, the parties wish to enter into this Agreement pursuant to which the Investor will purchase from the Sponsor Class B ordinary shares, par value $0.0001 per share, of the SPAC (the “Founder Shares”) for the same value paid by the Sponsor, or approximately $0.005 per share.

NOW THEREFORE, the parties hereto hereby agree as follows:

Section 1. Sale and Purchase

(a) In connection with the IPO Indication the Sponsor hereby agrees to sell to the Investor 503,125 Founder Shares (such shares, the “Transferred Shares”) for an aggregate purchase price of $2,500.00 (the “Transfer Price”) on the date hereof, and the Investor hereby agrees to purchase the Transferred Shares (the “Transfer”). Concurrently with the Transfer, in consideration for the transfer of the Transferred Shares, the Investor shall pay $2,500.00 to the Sponsor in immediately available funds.

(b) Subject to the Investor’s payment of the Transfer Price as contemplated by Section 1(a) of this Agreement, the Transfer shall occur and be effective as of the date hereof, automatically and without any action of any other party hereto.

(c) In the event that the Investor fails to fulfil the IPO Indication (which shall include the acquisition of 100% of the units of the SPAC allocated to the Investor by the underwriters in the IPO) the Transferred Shares shall be transferred at the Transferred Price to the Sponsor.

Section 2. Forfeiture of Founder Shares and Redemption Rights

(a) The Investor hereby irrevocably and unconditionally agrees to the Company satisfying any forfeiture requirement of Founder Shares in any circumstances, including, but not limited to, an over-allotment exercise or a change in investment by the Sponsor’s officers or managing entity to facilitate an initial Business Combination, resulting in the forfeiture, repurchase or surrender of Founder Shares.

(b) In the event that the Investor sells any Public Units or underlying Class A Ordinary Shares (including Class A Ordinary Shares exercised pursuant to a Warrant) prior to the closing of the initial business combination, the Investor hereby irrevocably and unconditionally agrees to transfer the Transferred Shares to the Sponsor at the Transferred Price, in an amount equal to the ratio of number of Public Units purchased by the Investor in the IPO minus the number of Public Units or Class A Ordinary Shares held by the Investor immediately prior to the closing of the initial Business Combination and the number of Public Units purchased by the Investor in the IPO.
