<P STYLE="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in">Arista Power, Inc.
(the &ldquo;Company&rdquo;) was advised by its independent registered accounting firm, EFP Rotenberg, LLP (&ldquo;EFPR&rdquo;),
of its intention to cease serving as the Company&rsquo;s independent registered public accounting firm upon the Company identifying
a successor firm. The Company understands that the basis for EFPR&rsquo;s decision is that EFPR has made a strategic decision to
serve public companies in roles other than as the independent auditor. On December 23, 2014, the Company engaged <FONT STYLE="background-color: white">Zwick
&amp; Banyai PLLC </FONT>(&ldquo;<FONT STYLE="background-color: white">Zwick &amp; Banyai</FONT>&rdquo;) as the Company&rsquo;s
independent registered public accounting firm, and EFPR resigned as the Company&rsquo;s independent registered public accounting
firm. The decision to engage <FONT STYLE="background-color: white">Zwick &amp; Banyai </FONT>was approved by the audit committee
of the Company&rsquo;s board of directors. EFPR has informed the Company that it will cooperate and assist with an orderly transition
of audit firms and the Company has authorized EFPR to respond fully to any inquiries of the successor auditor.</P>

<P STYLE="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in">EFPR&rsquo;s reports
on the financial statements of the Company for each of the past two fiscal years have neither contained an adverse opinion or a
disclaimer of opinion, nor been qualified or modified as to uncertainty, audit scope or accounting principles, except that, the
reports included an explanatory paragraph with respect to the uncertainty as to the Company&rsquo;s ability to continue as a going
concern. During the past two fiscal years and in the subsequent interim period through December 23, 2014, there were (i) no disagreements
with EFPR on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure, which
disagreements, if not resolved to the satisfaction of EFPR, would have caused it to make reference to the subject matter of the
disagreements in connection with its reports, and (ii) there were no reportable events (as that term is defined in Item 304(a)(1)(v)
of Regulation S-K).</P>

with a copy of the disclosures made in this Current Report on Form 8-K and requested that EFPR furnish a letter addressed to the
Securities and Exchange Commission stating whether or not it agrees with the disclosures. A copy of such letter, dated December
29, 2014, is filed as Exhibit 16.1 to this report.</P>
