Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]	NOTE 1 - OVERVIEW The Company Principal Solar, Inc. (“PSI”, the “Company”, “our”, “us”, or “we”) was incorporated on July 8, 2010, under the laws of the State of Texas and became a New York corporation upon consummation of a reverse merger. On March 7, 2011, the Company was acquired by Kupper Parker Communications, Inc. (“KPCG”), then a public shell company, in a reverse merger transaction whereby KPCG merged with and into PSI, with KPCG remaining as the surviving corporation and PSI becoming a wholly owned subsidiary of KPCG. In connection with the merger, the Company changed its corporate name from “Kupper Parker Communications, Inc.” to “Principal Solar, Inc.”. In accordance with the terms of this transaction, the shareholders of PSI exchanged all of their shares of PSI's $.01 par value common stock ("Common Stock") for shares of KPCG common stock that, immediately following the transaction, represented approximately 82 percent of the issued and outstanding Common Stock of the Company. In October 2012, the Company was re-domiciled in Delaware. The Company was authorized to issue 300,000,000 shares of Common Stock with a par value of $.01 per share and 100,000,000 shares of preferred stock with a par value of $0.01 per share ("Preferred Stock"). In April 2016, the Company amended its Certificate of Incorporation reducing authorized shares to 15,000,000 shares of Common Stock and 2,000,000 shares of preferred stock. Par value of $.01 per share remained unchanged. PSI is traded on the OTCPink ® market under the symbol "PSWW". Business Historically, our business plan has been to acquire, build, own, and operate profitable, large-scale solar generation facilities (collectively, "solar development"). The Company has failed to secure sufficient project financing to build large-scale solar generation facilities as planned, and is not considering any new large utility-scale solar projects at this time. Currently, the Company is negotiating to assign its interest in its Sunrise V (IS 42) project in order to create liquidity or otherwise remove obligations of the Company regarding current projects. See "Disposition of Sunrise V". The consummation of any agreement is subject to entering into a separate construction contract, and final closing is subject to the buyer securing financing and other conditions, some of which may be beyond the Company’s control. If all of the conditions are satisfied, the consummation of the assignment is expected to occur in the second quarter of 2016. See discussion below under "Disposition of Principal Sunrise V". The Company is also considering disposition of its remaining development projects acquired in partnership with Arowana International Limited ("Arowana"). See discussion herein under “Additional Projects”. Successful disposition of one or more of the Company's projects is necessary to the Company's ability to meet its obligations coming due during 2016. Failure to complete the dispositions, or complete them on expected terms, could cause the Company to lose its cumulative investment in one or more of the projects and cause it to cease operations. The Company sold its primary operating facility, Powerhouse One, LLC, effective July 1, 2015, from which it had generated approximately 96% of its revenues in 2015 and 2014. The remaining operating facility, SunGen StepGuys, LLC, was written-off in December 2015, as an impaired asset. Basis of Presentation The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the U.S. ("GAAP") and the rules of the Securities and Exchange Commission. In the opinion of management, all adjustments, consisting of normal recurring adjustments, necessary for a fair presentation of the periods presented have been reflected herein. Going Concern The accompanying consolidated financial statements have been prepared assuming the Company will continue as a going concern. As of December 31, 2015, the Company has an accumulated deficit of approximately $11.0 million, and the Company has had negative cash flows from operations since inception. Further, the Company is not considering any new large utility-scale solar projects at this time. Its ability to continue as a going concern is dependent upon the ability of the Company to collect its amounts receivable and dispose of its remaining development assets under development in order to meet its obligations, pay its liabilities arising from normal business operations when they come due, and potentially develop and execute upon a new business strategy. The outcome of these matters cannot be predicted with any certainty at this time and raise substantial doubt that the Company will be able to continue as a going concern. These consolidated financial statements do not include any adjustments to the amounts and classification of assets and liabilities that may be necessary should the Company be unable to continue as a going concern. Concentration Historically, approximately 96% of our consolidated power generation revenue arose from our Powerhouse One solar installation. The Powerhouse One subsidiary was sold in August 2015 (see NOTE 5, "Sale of Powerhouse One"). Reverse Stock Split On May 5, 2015, the Company's Board of Directors and stockholders representing a majority of the shares outstanding on that date voted to effect a 1:4 reverse stock split (the "May 2015 Reverse"). Unless otherwise stated or the context would require otherwise, all share amounts disclosed throughout these financial statements retroactively take into account the May 2015 Reverse, and all resulting fractional share amounts have been rounded to the nearest whole share. On May 6, 2015, the Company amended its Certificate of Incorporation with the State of Delaware reflecting the May 2015 Reverse.
