Overview

We are one of the largest commercial solar engineering, procurement and construction (“EPC”) companies in the country and are expanding across the Northeastern United States. We were a second-generation family business founded under the name Peck Electric Co. in 1972 as a traditional electrical contractor. Our core values were and still are to align people, purpose, and profitability, and since taking leadership in 1994, Jeffrey Peck, our Chief Executive Officer, has applied such core values to expand into the solar industry. Today, we are guided by the mission to facilitate the reduction of carbon emissions through the expansion of clean, renewable energy and we believe that leveraging such core values to deploy resources toward profitable business is the only sustainable strategy to achieve these objectives.

The world recognizes the need to transition to a reliable, renewable energy grid in the next 50 years. Vermont and Hawaii are leading the way in the U.S. with renewable energy goals of 75% by 2032 and 100% by 2045, respectively. California committed to 100% carbon-free energy by 2045. The majority of the other states in the U.S. also have renewable energy goals, regardless of current Federal solar policy. We are a member of Renewable Energy Vermont, an organization that advocates for clean, practical and renewable solar energy. We intend to use near-term incentives to take advantage of long-term, sustainable energy transformation with a commitment to the environment and to our shareholders. Our triple bottom line, which is geared towards people, environment, and profit, has always been our guide since we began installing renewable energy and we intend that it remain our guide over the next 50 years as we construct our energy future.

We primarily provide EPC services to solar energy customers for projects ranging in size from several kilowatts for residential loads to multi-megawatt systems for large commercial and utility projects. To date, we have installed over 400 megawatts of solar systems since inception and are focused on profitable growth opportunities. We believe that we are well-positioned for what we believe to be the coming transformation to an all renewable energy economy. We are expanding across the Northeastern United States to serve the fast-growing demand for clean renewable energy. We are open to partnering with others to accelerate our growth process, and we are expanding our portfolio of company-owned solar arrays to establish recurring revenue streams for many years to come. We have established a leading presence in the market after five decades of successfully serving our customers, and we are now ready for new opportunities and the next five decades of success. As part of our business strategy in 2021 we acquired iSun Energy, LLC, the intellectual property of Oakwood Construction Services, Inc, SolarCommunities, Inc. d/b/a SunCommon and Liberty Electric, Inc in order to provide our full suite of services to the residential, community, commercial, industrial and utility solar markets.

RISK FACTORS

An investment in our Common Stock involves significant risks. You should carefully consider the risk factors contained in any Prospectus Supplement and in our filings with the SEC, including our Annual Report on Form 10-K for the year ended December 31, 2021 filed on April 15, 2022, and Form 10-K/A on May 2, 2022, our Form 10-Q for the quarterly period ended March 31, 2022 filed on May 16, 2021, our Form 10-Q for the quarterly period ended June 30, 2022 filed on August 15, 2022, our form 10-Q for the quarterly period ended September 30, 2022, filed on November 14, 2022, as well as all of the information contained in this Prospectus, any Prospectus Supplement and the documents incorporated by reference herein or therein, before you decide to invest in our Common Stock. Our business, prospects, financial condition and results of operations may be materially and adversely affected as a result of any of such risks. The value of our Common Stock could decline as a result of any of these risks. You could lose all or part of your investment in our Common Stock. Some of our statements in sections entitled “Risk Factors” are forward-looking statements. The risks and uncertainties we have described are not the only ones we face. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also affect our business, prospects, financial condition and results of operations.

A substantial number of shares of our Common Stock may be issued pursuant to the conversion terms of the Convertible Notes, which could cause the price of our Common Stock to decline.

The Convertible Notes are immediately convertible upon issuance into shares of our Common Stock at a conversion price of $2.66 per share, for an aggregate of approximately 4,699,249 shares (based on $12,500,000 in aggregate principal amount outstanding as of such date) without taking into account the accumulation of interest or the limitations on the conversion of the Convertible Notes as described elsewhere in this Prospectus. The issuance of these shares will dilute our other equity holders, which could cause the price of our Common Stock to decline.

Sales of substantial amounts of our Common Stock by the Selling Stockholders, or the perception that these sales could occur, could adversely affect the price of our Common Stock.

The sale by the Selling Stockholders of a significant number of shares of Common Stock could have a material adverse effect on the market price of our Common Stock. In addition, the perception in the public markets that the Selling Stockholders may sell all or a portion of their shares as a result of the registration of such shares for resale pursuant to this Prospectus could also in and of itself have a material adverse effect on the market price of our Common Stock. We cannot predict the effect, if any, that market sales of those shares of Common Stock or the availability of those shares of Common Stock for sale will have on the market price of our Common Stock.

The requirement that we repay the Convertible Notes and interest thereon in cash could adversely affect our business plan, liquidity, financial condition, and results of operations.

If not converted, we are required to repay principal amounts outstanding under the Convertible Notes and interest thereon in cash. These obligations could have important consequences on our business. In particular, they could:

	●	limit our flexibility in planning for, or reacting to, changes in our businesses and the industries in which we operate;
	●	increase our vulnerability to general adverse economic and industry conditions; and
	●	place us at a competitive disadvantage compared to our competitors.

No assurances can be given that we will be successful in making the required payments under the Convertible Notes.

If we are unable to make the required cash payments, there could be a default under the Convertible Notes. In such event, or if a default otherwise occurs under the Convertible Notes, including as a result of our failure to comply with the financial or other covenants contained therein, the holders of the Convertible Notes could cause the Convertible Notes to accrue interest at the rate of 10% per annum. In addition, the holders could exercise their remedies as secured creditors as provide in a Security Agreement dated November 4, 2022.

Restricted covenants under the Convertible Notes could limit our growth and our ability to finance our operations, fund our capital needs, respond to changing conditions and engage in other business activities that maybe in our best interests.

The Convertible Notes contain a number of affirmative and negative covenants regarding the payment of dividends, maintenance of its property, transactions with affiliates, and issue notes and certain securities.

Our ability to comply with these covenants may be adversely affected by events beyond our control, and we cannot assure you that we can maintain compliance with these covenants. The financial covenants could limit our ability to make needed expenditures or otherwise conduct necessary or desirable business activities.

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

PRIVATE PLACEMENT OF THE CONVERTIBLE NOTES

On November 4, 2022, we entered into a Securities Purchase Agreement (the “Purchase Agreement”) with Anson Investments Master Fund LP and Anson East Master Fund LP (the “Investors”) and consummated the sale to the Investors of the Senior Secured Convertible Notes (the “Convertible Notes”) with an aggregate initial principal amount of $12,500,000. The Notes were sold with an original issue discount of $750,000. The Investors paid for the Notes to be issued by delivering $11,750,000 in cash consideration.

Upon (i) the effectiveness of this Registration Statement covering the Registrable Securities, (ii) the Stockholder Approval (as defined in the Purchase Agreement), (iii) the Company’s achievement of certain revenue and EBITDA targets, (iv) the Company having sufficient authorized shares of Common Stock, (v) the Company’s maintenance of certain balance sheet requirements, and (vi) certain other conditions, the Company and the Investors will consummate a second closing in which the Company will issue and sell to each Investor a second Note for an aggregate principal amount of $12,500,000 having identical terms and conditions as the first Note, including a six percent (6%) original issue discount, for an aggregate principal amount of $25,000,000 in Notes that may be issued and sold pursuant to the Purchase Agreement.

Alliance Global Partners / A.G.P. (“AGP”) was engaged as the sole placement agent for the offering of the Convertible Notes. AGP received a placement agent fee of $718,750 at the closing of the Private Placement, representing 6.1% of the gross cash proceeds at the closing. After deducting the placement agent fee, the Company’s estimated expenses associated with the Private Placement and the repayment of certain indebtedness of the Company, the Company’s estimated net cash proceeds at the closing were approximately $632,461.61.

Purchase Agreement

The Purchase Agreement contains certain representations and warranties, covenants and indemnities customary for similar transactions.

Convertible Notes

The Notes were issued to the Investors on November 4, 2022 and mature on May 4, 2025 (the “Maturity Date”). Interest shall accrue under the Notes at the rate of 5% per annum, payable in cash or, at the Company’s option, in duly authorized, validly issued, fully paid and non-assessable shares of the Company’s Common Stock, or a combination thereof. The Notes are convertible into shares of Common Stock at the election of the holder at any time at an initial conversion price of $2.66 (the “Conversion Price”). The Conversion Price is subject to customary adjustments for stock dividends, stock splits, reclassifications and the like, and subject to price-based adjustment in the event of any issuances of Common Stock, or securities convertible, exercisable or exchangeable for, Common Stock at a price below the then-applicable Conversion Price (subject to certain exceptions). Beginning on March 1, 2023 and on the first day of each month thereafter, the Company will be required to redeem 1/26th of the original principal amount of each Note, plus accrued but unpaid interest, until the maturity date of May 4, 2025, on which date all amounts that remain outstanding will be due and payable in full. Subject to certain conditions, including certain equity conditions, the Company may pay the amount due on each monthly redemption date, and the final amount due at maturity, either in cash, shares of Common Stock or a combination thereof. The number of shares used to pay any portion of the Notes in such event would be calculated as 90% of the lowest daily volume weighted average price of the Common Stock during the five (5) trading days immediately prior to the payment date. The Notes may not be prepaid by the Company, other than as specifically permitted by the Notes.

The Notes rank senior to all outstanding and future indebtedness of the Company and its Subsidiaries (as defined in the Purchase Agreement), subject to certain exclusions including (i) existing debt relating to bank loans to the Company’s subsidiary Peck Electric, Co., a Vermont corporation, secured by certain solar arrays, and (ii) existing vehicle and equipment loans to the Company’s subsidiaries, Peck Electric Co., a Vermont corporation and SolarCommunities, Inc., a Vermont benefit corporation, secured by those vehicles and equipment, and is secured by a first priority perfected security interest in all of the existing and future assets of the Company and each Guarantor (as defined in the Security Agreement), as evidenced by (i) a Security Agreement entered into at the Closing (the “Security Agreement”), (ii) a Trademark Security Agreement entered into at the Closing (the “Trademark Security Agreement”), and (iii) a Guaranty executed by all direct and indirect subsidiaries of the Company (the “Guaranty”) pursuant to which each of them has agreed to guaranty the obligations of the Company under the Notes and the other Transaction Documents (as defined in the Purchase Agreement).

Conversion Limitation

The Investors will not have the right to convert any portion of a Convertible Notes, to the extent that, after giving effect to such conversion, the Investor (and other certain related parties) would beneficially own in excess of 4.99% of the shares of Common Stock outstanding immediately after giving effect to such conversion. This limit may, from time to time, be increased, up to 9.99%, or decreased; provided that any such increase will not be effective until the 61st day after delivery of a notice to the Company of such increase.

Events of Default

The Convertible Notes include certain customary and other Events of Default. In connection with an Event of Default, the Investor may require the Company to redeem in cash any or all of the Convertible Notes. The redemption price will be at a premium to the amount due under the Convertible Notes as described therein.

Covenants

The Company will be subject to certain customary affirmative and negative covenants including those regarding the payment of dividends, maintenance of its property, transactions with affiliates, and issue notes and certain securities.

Company Optional Redemption Rights

The Company may redeem the Convertible Notes at the redemption price described in the Convertible Notes.

Registration Rights Agreement

The Company entered into a Registration Rights Agreement (the “Registration Rights Agreement”) with the Investors. Pursuant to the terms of the Registration Rights Agreement, the Company has agreed to prepare and file with the SEC within 20 days following the Closing a Registration Statement covering the resale of the shares of Common Stock issuable upon conversion of the Notes (the “Registrable Securities”), and to use its best efforts to cause such Registration Statement to be declared effective under the Securities Act of 1933, as amended (the “Securities Act”), as promptly as possible, but in any event no later than 60 days following the Closing. If the Registration Statement is not filed within 20 days after the Closing (extended by the Company and the Investors to December 5, 2022) or is not declared effective by the applicable deadline set forth in the Registration Rights Agreement, or under certain other circumstances described in the Registration Rights Agreement, then the Company shall be obligated to pay, as partial liquidated damages, to each Investor an amount in cash equal to 2% of the original principal amount of the Notes each month until the applicable event giving rise to such payments is cured. If the Company fails to pay any partial liquidated damages in full within seven days after the date payable, the Company will pay interest thereon at a rate of 10% per annum.

Additional Information

The foregoing is only a summary of the material terms of the Purchase Agreement, the Convertible Notes, the Registration Rights Agreement and the other ancillary transaction documents (collectively, the “Transaction Documents”), and does not purport to be a complete description of the rights and obligations of the parties thereunder.

The summary of the Transaction Documents is qualified in its entirety by reference to the forms of such agreements, which are filed as exhibits to the Company’s Current Report on Form 8-K, filed November 8, 2022, and incorporated herein by reference.

The foregoing summary and the exhibits hereto also are not intended to modify or supplement any disclosures about the Company in the Company’s reports filed with the SEC. In particular, the agreements and the related summary are not intended to be, and should not be relied upon, as disclosures regarding any facts and circumstances relating to the Company or any of its subsidiaries or affiliates. The agreements contain representations and warranties by the Company, which were made only for purposes of that agreements and as of specified dates. The representations, warranties and covenants in the agreements were made solely for the benefit of the parties to the agreements; may be subject to limitations agreed upon by the contracting parties, including being subject to confidential disclosures that may modify, qualify or create exceptions to such representations and warranties; may be made for the purposes of allocating contractual risk between the parties to the agreements instead of establishing these matters as facts; and may be subject to standards of materiality applicable to the contracting parties that differ from those applicable to the Investors. In addition, information concerning the subject matter of the representations, warranties and covenants may change after the date of the agreements, which subsequent information may or may not be fully reflected in the Company’s public disclosures.

As of the date of this Prospectus, we believe that we will have the financial ability to make the majority of payments on the Convertible Notes in cash when due. Accordingly, we do intend, as of the date of this Prospectus, to make such payments in shares of our Common Stock when operating cash flow is not available to satisfy the amortization of the Convertible Note.

We have not had any material relationships or arrangements with the Selling Stockholders, their affiliates, or any person with whom the Selling Stockholders have a contractual relationship regarding this private placement (or any predecessors of those persons).

No assurances can be given that we will be successful in satisfying the conditions, complying with certain of the terms and conditions in the issuance of the convertible notes or in arranging further funding, if needed, or if successful to continue the execution of our business plan including the development and commercialization of new products. Failure to obtain such funding will require management to substantially curtail, if not cease operations, which will result in a material adverse effect on the financial position and our results of operations.

USE OF PROCEEDS

The Selling Stockholders will receive all of the proceeds from the sale of shares of Common Stock under this Prospectus. We will not receive any proceeds from these sales. The Selling Stockholders will pay any agent’s commissions and expenses they incur for brokerage, accounting, tax or legal services or any other expenses that they incur in disposing of the shares of Common Stock. We will bear all other costs, fees and expenses incurred in effecting the registration of the shares of Common Stock covered by this Prospectus and any Prospectus Supplement. These may include, without limitation, all registration and filing fees, SEC filing fees and expenses of compliance with state securities or “blue sky” laws.

SELLING STOCKHOLDERS

The shares of Common Stock being offered by the Selling Stockholders are those issuable to the Selling Stockholders upon conversion of the Convertible Notes. For additional information regarding the issuance of the Convertible Notes, see “Private Placement of the Convertible Notes” above. We are registering the shares of Common Stock in order to permit the Selling Stockholders to offer the shares for resale from time to time. Except for the ownership of the Convertible Notes issued pursuant to the Securities Purchase Agreement, the Selling Stockholders have not had any material relationship with us within the past three years.

The table below lists the selling stockholders and other information regarding the beneficial ownership (as determined under Section 13(d) of the Securities Exchange Act of 1934, as amended, and the rules and regulations thereunder) of the shares of Common Stock held by the Selling Stockholders. The second column lists the number of shares of Common Stock beneficially owned by the Selling Stockholders, as of November 4, 2022, assuming conversion of the Convertible Notes held by the Selling Stockholders on that date but taking account of any limitations on conversion set forth therein. The third column lists the shares of Common Stock being offered by this prospectus by the Selling Stockholders and does not take in account any limitations on conversion of the notes set forth therein.

Under the terms of the Convertible Notes, a selling stockholder may not convert the notes to the extent (but only to the extent) such selling stockholder or any of its affiliates would beneficially own a number of shares of our Common Stock which would exceed 4.99% of the outstanding shares of the Company. The number of shares in the second column reflects these limitations. The Selling Stockholders may sell all, some or none of their shares in this offering. See “Plan of Distribution.”

PLAN OF DISTRIBUTION

The Selling Stockholders and any of their respective pledgees, assignees and successors-in-interest may, from time to time, sell any or all of their securities covered hereby on any trading market, stock exchange or other trading facility on which the securities are traded or in private transactions. These sales may be at fixed or negotiated prices. The Selling Stockholders may use any one or more of the following methods when selling securities:

	●	ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;

	●	block trades in which the broker-dealer will attempt to sell the securities as agent but may position and resell a portion of the block as principal to facilitate the transaction;

	●	purchases by a broker-dealer as principal and resale by the broker-dealer for its account;

	●	an exchange distribution in accordance with the rules of the applicable exchange;

	●	privately negotiated transactions;

	●	settlement of short sales;

	●	in transactions through broker-dealers that agree with the Selling Stockholders to sell a specified number of such securities at a stipulated price per security;

	●	through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise;

	●	a combination of any such methods of sale; or

	●	any other method permitted pursuant to applicable law.

The Selling Stockholders may also sell securities under Rule 144 under the Securities Act, if available, rather than under this Prospectus.

Broker-dealers engaged by the Selling Stockholders may arrange for other brokers-dealers to participate in sales. Broker-dealers may receive commissions or discounts from the Selling Stockholders (or, if any broker-dealer acts as agent for the purchaser of securities, from the purchaser) in amounts to be negotiated, but, except as set forth in a supplement to this prospectus, in the case of an agency transaction not in excess of a customary brokerage commission in compliance with FINRA Rule 2440; and in the case of a principal transaction a markup or markdown in compliance with FINRA IM-2440.

In connection with the sale of the securities covered hereby, the Selling Stockholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the securities in the course of hedging the positions they assume. The Selling Stockholders may also sell securities short and deliver these securities to close out their short positions, or loan or pledge the securities to broker-dealers that in turn may sell these securities. The Selling Stockholders may also enter into option or other transactions with broker-dealers or other financial institutions or create one or more derivative securities which require the delivery to such broker-dealer or other financial institution of securities offered by this prospectus, which securities such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).

The Selling Stockholders and any broker-dealers or agents that are involved in selling the securities may be deemed to be “underwriters” within the meaning of the Securities Act in connection with such sales. In such event, any commissions received by such broker-dealers or agents and any profit on the resale of the securities purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act. Each Selling Stockholder has informed us that it does not have any written or oral agreement or understanding, directly or indirectly, with any person to distribute the securities.

We are required to pay certain fees and expenses incurred by us incident to the registration of the securities. We have agreed to indemnify the Selling Stockholders against certain losses, claims, damages and liabilities, including liabilities under the Securities Act.

Because the Selling Stockholders may be deemed to be an “underwriter” within the meaning of the Securities Act, they will be subject to the prospectus delivery requirements of the Securities Act, including Rule 172 thereunder. In addition, any securities covered by this Prospectus which qualify for sale pursuant to Rule 144 under the Securities Act may be sold under Rule 144 rather than under this Prospectus. Each Selling Stockholder has advised us that there is no underwriter or coordinating broker acting in connection with the proposed sale of the resale securities by the Selling Stockholder.

We agreed to keep this Prospectus effective until the earlier of (i) the date on which the securities may be resold by the Selling Stockholders without registration and without regard to any volume or manner-of-sale limitations by reason of Rule 144, without the requirement for us to be in compliance with the current public information requirement under Rule 144 under the Securities Act or any other rule of similar effect or (ii) all of the securities have been sold pursuant to this prospectus or Rule 144 under the Securities Act or any other rule of similar effect. The resale securities will be sold only through registered or licensed brokers or dealers if required under applicable state securities laws. In addition, in certain states, the resale securities covered hereby may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from the registration or qualification requirement is available and is complied with.

Under applicable rules and regulations under the Exchange Act, any person engaged in the distribution of the resale securities may not simultaneously engage in market making activities with respect to the Common Stock for the applicable restricted period, as defined in Regulation M, prior to the commencement of the distribution. In addition, the Selling Stockholders will be subject to applicable provisions of the Exchange Act and the rules and regulations thereunder, including Regulation M, which may limit the timing of purchases and sales of the Common Stock by the Selling Stockholders or any other person. We will make copies of this Prospectus available to the Selling Stockholders and have informed the Selling Stockholders of the need to deliver a copy of this prospectus to each purchaser at or prior to the time of the sale (including by compliance with Rule 172 under the Securities Act).
