REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders

Real Goods Solar, Inc.

Louisville, Colorado

We have audited the accompanying balance sheets of Elemental Energy LLC, dba Sunetric as of December 31, 2013 and 2012, and the related statements of operations, changes in members’ (deficit) equity, and cash flows for the years then ended. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Company is not required to have, nor were we engaged to perform an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of Elemental Energy LLC, dba Sunetric as of December 31, 2013 and 2012, and the results of its operations and its cash flows for each of the years in the two periods ended December 31, 2013, in conformity with accounting principles generally accepted in the United States of America.

Notes to Financial Statements

Note 1 - Description of Business and Summary of Significant Accounting Policies

Elemental Energy LLC, dba Sunetric (the “Company”) was incorporated under the laws of the state of Hawaii on January 27, 2004. The Company is a licensed solar power contractor in the state of Hawaii and provides solutions for photovoltaic systems, including design; development; installation; and consultation for financing, monitoring, and maintenance. The Company is a renewable energy solutions provider specializing in photovoltaic or solar electric installations for commercial and residential clients in Hawaii. Consequently, the Company’s ability to collect the amounts due from customers may be affected by economic fluctuations within the state.

Cash and Cash Equivalents

The Company considers all highly liquid instruments purchased with an original maturity of three months or less to be cash equivalents. The Company continually monitors its positions with, and the credit quality of, the financial institutions with which it invests. As of the balance sheet date, and periodically throughout the year, the Company has maintained balances in various operating accounts in excess of federally insured limits.

Accounts Receivable

The Company provides an allowance for doubtful accounts equal to the estimated uncollectible amount. The Company’s estimate is based on historical collection experience and a review of the current status of accounts receivable. It is reasonably possible that the Company’s estimate of the allowance for doubtful accounts will change and that losses ultimately incurred could differ materially from the amounts estimated in determining the allowance. At December 31, 2013 and 2012, the Company had allowances for doubtful accounts of $100,000 for both years.

Inventory

Inventory consists of finished goods and is stated at the lower of cost or market, determined using the first-in, first-out method. A valuation allowance is provided for obsolete and slow moving inventory to write its cost down to net realizable value (market), if necessary. At December 31, 2013 and 2012, the valuation allowance was $135,359 and $24,757, respectively.

Prepaid Expenses and Deposits

Prepaid expenses and deposits consist primarily of insurance, rent, security deposits, and other expenses paid in advance.

Property and Equipment

Property and equipment are stated at cost. Depreciation is provided utilizing the straight-line method over the estimated useful lives for owned assets, ranging from three to five years.

Notes to Financial Statements

Note 1 - Description of Business and Summary of Significant Accounting Policies (continued)

Income Taxes

The Company has elected to be treated as a partnership for income tax purposes. Accordingly, taxable income and losses of the Company are reported on the income tax returns of the Company’s members, and no provision for federal income taxes has been recorded in the accompanying financial statements.

The Company follows the guidance of Accounting Standards Codification (“ASC”) Topic 740, Accounting for Uncertainty in Income Taxes. ASC Topic 740 prescribes a more-likely-than-not measurement methodology to reflect the financial statement impact of uncertain tax positions taken or expected to be taken in a tax return. If taxing authorities were to disallow any tax positions taken by the Company, the additional income taxes, if any, would be imposed on the members rather than the Company.

Interest and penalties associated with tax positions are recorded in the period assessed as general and administrative expenses. However, no interest or penalties have been assessed as of December 31, 2013 and 2012. The Company’s tax returns subject to examination by tax authorities include 2010 through the current period for state and federal tax reporting purposes, respectively.

Revenue Recognition

The Company recognizes revenue from fixed-price and guaranteed maximum-price construction contracts on the percentage-of-completion method, measured by the percentage of costs incurred to date to management’s estimated total contract costs for each contract. This method is used because management considers cost to date to be the best available measure of progress on these contracts. Revenues from cost-plus-fee contracts are recognized on the basis of costs incurred during the period plus the fee earned. Changes in job performance, job conditions, and estimated profitability may result in material revisions to costs and revenues in the next year.

Contract costs include direct contract costs, such as materials, subcontractors, labor, payroll insurance and taxes, other sundry direct costs; and indirect contract costs, such as unallocated labor, travel pay, supplies, tools, rent, repairs, insurance, and depreciation. General and administrative costs are charged to expense as incurred. Contract costs and estimates of costs to complete contracts are reviewed and updated periodically by project managers. Provisions for estimated losses on uncompleted contracts are recorded in the period in which such losses are determined. Changes in job performance, job conditions, and estimated profitability may result in revisions to costs and income and are recognized in the period in which the revisions are determined. Changes in estimated job profitability resulting from job performance, job conditions, and contract penalty provisions, claims, change orders, and final contract settlements are accounted for as changes in estimates in the current period. Profit incentives are included in revenues when earned and their realization is reasonably assured.

The asset account, costs and estimated earnings in excess of billings on uncompleted contracts, represents revenues recognized and earned in excess of amounts billed. The liability account, billings in excess of costs and estimated earnings on uncompleted contracts, represents billings in excess of revenues recognized and earned.

Advertising and Marketing Costs

The Company expenses advertising costs as incurred. Advertising and marketing expenses for the years ended December 31, 2013 and 2012 were $1,267,576 and $677,027, respectively.

Unapproved Change Orders and Claims

Costs related to change orders and claims are recognized when they are incurred. Change orders are included in total estimated contract revenue when it is probable that the change order will result in additional contract value and can be reliably estimated. Estimated contract revenue associated with change orders may include amounts in excess of incurred costs (profit) when appropriate.

Warranty Liability

The Company offers ten-year warranties for installation defects over the course of a warranty, as defined. The Company estimates the warranty liability to be 1% of revenues earned. The Company estimates the current portion of the liability based on average warranty expenses over a rolling 12-month period.

The following table summarizes the activity for the accrual of warranties:

	For the Years Ended December 31,
	2013			2012
Balance at January 1	$	1,537,880		$	250,000
Payments made		(322,009	)		—
Current year accrual		224,169			1,287,880
Balance as of December 31	$	1,440,040		$	1,537,880

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

The financial statements include some amounts that are based on management’s best estimates and judgments. The most significant estimates relate to allowance for uncollectible accounts receivable, warranty reserves, inventory obsolescence, depreciation, employee benefit plans, taxes, contingencies, and costs to complete long-term contracts. These estimates may be adjusted as more current information becomes available, and any adjustment could be significant.

Subsequent Events

The Company has evaluated all subsequent events through the auditors’ report date, which is the date the financial statements were available for issuance. With the exception of those matters discussed in Note 9, there were no material subsequent events that required recognition or additional disclosure in these financial statements.

Note 2 - Related Party Transactions

On June 15, 2012, the Company entered into a $250,000 loan agreement with a member with interest at a rate of 2.07%. The balance as of December 31, 2012 was $252,588. During the year ended December 31, 2013, the Company reclassified the balance due as a distribution to the member.

The Company periodically makes advances to employees of the Company. Due from related party balance as of December 31, 2013 and 2012 was $6,455 and $0, respectively.

During 2012, certain customers elected to enter into purchase power agreements with affiliates of the Company (“PPA Affiliates”) instead of purchasing equipment. The PPA Affiliates used the Company to perform the installations. For the year ended December 31, 2012, total revenues earned from PPA Affiliates were approximately $1,107,000.

Note 3 - Property and Equipment, Net
