Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Description of Business	Organization and Description of Business Description of Business Spruce Power Holding Corporation and its subsidiaries (“Spruce Power” or the “Company”) is a leading owner and operator of distributed solar energy assets across the U.S., offering subscription-based services to approximately 83,000 home solar assets and customer contracts, making renewable energy more accessible to everyone. The Company is engaged in the ownership and maintenance of home solar energy systems for homeowners in the U.S. The Company’s primary customers are homeowners and its core solar service offerings to these customers generate revenues primarily through (i) the sale of electricity generated by its home solar energy systems to homeowners pursuant to long-term Customer Agreements as defined below, which require the homeowners to make recurring monthly payments, (ii) third-party contracts to sell solar renewable energy credits (“SRECs”) generated by the Company’s home solar energy systems for contracted prices, and (iii) the servicing of third-party owned solar energy systems through the Company’s Spruce Pro servicing platform, which is contracted to offer portfolio managed services to third-party owners, as well as to the Company’s portfolio of home solar energy systems (the “Portfolio”). These portfolio managed services include (a) billing and collections/asset recovery, (b) account support services, (c) financial asset management, (d) homeowner support and servicing technology, (e) asset operations, and (f) transaction and execution services related to SRECs. In addition to the Company’s core solar service offerings, the Company generates cash flows and earns interest income from customer contracts related to a master lease agreement, which is referred to in these condensed consolidated financial statements as the “SEMTH Master Lease”. The Company holds subsidiary fund companies, defined below as the Funds, that own and operate the Company’s portfolio of home solar energy systems, which are subject to solar lease agreements (“SLAs”) and power purchase agreements (“PPAs”, together with the SLAs, “Customer Agreements”) with residential customers who benefit from the production of electricity generated by the Company’s portfolio of home solar energy systems, which may qualify for subsidies, renewable energy credits and other incentives as provided by the federal government and various states and local agencies. These benefits have generally been retained by the Company's subsidiaries that own the systems, with the exception of the investment tax credit (“ITCs”) under Section 48 of the Internal Revenue Code, as amended (the “IRC”), which were generally passed through to the various financing partners of the solar energy systems. Going Concern These condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) assuming the Company will continue as a going concern. The Company’s debt obligations under the SP1 Facility and SP2 Facility are non-recourse to the Company (see Note 7. Non-Recourse Debt). With regards to the SP1 Facility, on March 27, 2026, the Company entered into the SP1 Facility Amendment, as defined below, to extend the maturity of this facility to October 30, 2026 (the “Amended SP1 Maturity Date”), unless a signed term sheet for a long-term financing is obtained, in which case the extended maturity date will be January 30, 2027. The maturity date of the SP2 Facility is May 14, 2027 (the “SP2 Maturity Date”) and has been classified as current as of June 30, 2026, see Note 7. Because (i) the Amended SP1 Maturity Date and the SP2 Maturity Date are within twelve months from the date the accompanying unaudited condensed consolidated financial statements are issued, (ii) the Company has not yet entered into a commitment to refinance the SP1 or SP2 Facility, (iii) the Company has determined that it is unlikely to have sufficient cash on hand or proceeds from currently available liquidity sources to satisfy the SP1 Facility at the Amended SP1 Maturity Date or the SP2 Facility at the SP2 Maturity Date, (iv) the Company had negative working capital of $175.0 million as of June 30, 2026 due to the current maturity of the SP1 Facility and SP2 Facility, and (v) the Company has experienced negative cash flows from operations for the three months ended June 30, 2026 and 2025, these conditions raise substantial doubt about the Company’s ability to continue as a going concern. Our condensed consolidated financial statements do not include any adjustments that may result from the outcome of this uncertainty. The Company is working towards obtaining a signed term sheet for the SP1 Facility prior to the Amended SP1 Maturity Date, refinancing the SP1 Facility before the extended maturity date of January 30, 2027, and refinancing the SP2 Facility prior to the SP2 Maturity Date consistent with the Company’s historical financing strategy for investing in solar assets on a leveraged basis. The Company has engaged a financial advisor to assist the Company with potential lenders, which are currently being reviewed by management. However, the Company can offer no assurances it will be able to obtain financing at acceptable terms or at all. Therefore, the Company has concluded that there is substantial doubt about its ability to continue as a going concern. Should the Company be unsuccessful in refinancing the SP1 Facility or the SP2 Facility, this could result in a foreclosure of collateral and negatively impact operations. Further, (i) the failure to timely progress and consummate a refinancing of the SP1 Facility, SP2 Facility, and SP3 Facility in accordance with the requirements of the Second KeyBank Credit Agreement would trigger additional collateral (discussed in Note 7. Non-Recourse Debt), and (ii) the occurrence of a continuing event of default on the SP1 Facility, SP2 Facility, or SP3 Facility would result in a cross default on the Second KeyBank Credit Agreement.
