Receivables [Abstract]
Loans, Notes, Trade and Other Receivables Disclosure [Text Block]	8. Accounts and Notes Receivable During 2013, the Company recognized $13.9 million revenue under the completed-contract method and recorded a receivable of $8.8 million (originally denominated in euro’s) related to the sale of its Greece projects. Due to the delay in the customer receiving term financing from CDB, the receivable is currently being collected over a six year agreed upon payment schedule, plus variable interest. The difference of $5.1 million between revenue recognized and account receivable balance relates to prior payments received from the customer which had been recorded as a customer deposit within accrued liabilities. As of December 31, 2013, due to the extended collection period, $2.2 million of the accounts receivable is recorded as current and $6.6 million is recorded in accounts receivable, noncurrent. During the second quarter of 2013, the Company reclassified $5.9 million of existing accounts receivables from a second unrelated customer to noncurrent based on the expected collection period which is anticipated to exceed one year. As of December 31, 2013, the Company has $2.0 million recorded in accounts receivable, current and $5.8 million recorded in accounts receivable, noncurrent from this second customer. The Company agreed to advance to customer KDC predevelopment and site acquisition costs related to the Imclone EPC agreement between KDC and the Company and recorded the amount as notes receivable. The terms of the EPC agreement require repayment of the advance upon final completion of the SEF, which was expected to occur in the first half of 2013 but is now expected to occur in the first half of 2014 as the project did not break ground until the second quarter of 2013. The advance bears interest at the rate of 5% per year that is payable at the time the principal is repaid. The advance and related interest was collected in full in December 2013 as KDC obtained term debt financing for the project in December 2013. As of December 31, 2013and 2012, the balance of the note receivable from this project was none and $7.0 million, respectively. These amounts are recorded in the current notes receivable. During 2013 the Company issued a note receivable to KDC for one completed contract with 15 year payment terms which began on the commercial operations date which was April 2013. The note bears interest of LIBOR plus 460bps. If the customer obtains term debt financing for their project, the collection of the note receivable may be accelerated. During 2013 the Company issued another note receivable to KDC for the Mountain Creek project that has not been completed. In December 2013, the Company entered into an exchange and release agreement with KDC and agreed to exchange this note receivable due in exchange for a 64.50% limited ownership interest in KDC Solar Mountain Creek Parent LLC (see Note 10). As of December 31, 2013 and 2012, the balance recorded in noncurrent notes receivable related to this customer was $13.6 million and none, respectively. On April 27, 2012, the Company made a secured loan of $1.0 million to Solar Hub Utilities, LLC (“Solar Hub”), to be used for pre-development costs, and recorded the amount in the account notes receivable. On June 8, 2012, the Company agreed to advance Solar Hub up to $9.0 million under a new $9.0 million secured promissory note, which refinanced the original $1.0 million advance and bears a 6% annual interest rate. In March 2013, the interest was changed to a 10% annual interest rate in accordance with the Amended and Restated Secured Promissory Note. This note receivable is secured by the project assets. Repayment in full of all borrowed amounts was due on December 31, 2012 but, in March 2013, was extended to a new maturity date of July 1, 2014 in accordance with the Amended and Restated Secured Promissory Note.
