Revenue Recognition
The Company recognizes revenue when (i) persuasive evidence of an arrangement exists, (ii) delivery has occurred or services have been rendered, (iii) the sales price is fixed and determinable, and (iv) collection of the related receivable is reasonably assured.
Operating leases and incentives
Operating leases and incentives revenue is primarily comprised of revenue from Customer Agreements, revenue from solar energy system rebate incentives, revenue associated with ITCs assigned to investment funds that are classified as lease pass-through arrangements and revenue from the sales of SRECs generated by the Company’s solar energy systems to third parties.
The Company begins to recognize revenue on Customer Agreements when permission to operate (“PTO”) is given by the local utility company or on the date daily operation commences if utility approval is not required. The Company recognizes revenue on a straight-line basis over the initial term of the Customer Agreements (typically 20 years) that have minimum lease payments, or as earned when the customers are billed based on the actual electricity generated at a specific rate under the terms of the Customer Agreements.
The Company considers upfront rebate incentives received from states and utilities for solar energy systems subject to Customer Agreements to be minimum lease payments. Rebate revenue is recognized on a straight-line basis over the life of the initial contract term of the Customer Agreement beginning when a PTO letter is issued by the local utility company or on the date daily operation commences if utility approval is not required.
The Company monetizes the ITCs associated with the leased systems on its lease pass-through financing obligations by assigning them to the investor together with the future customer lease payments. A portion of the cash consideration received from the investors is allocated to the estimated fair value of the assigned ITCs upon the PTO dates of the leased systems, as discussed below. The estimated fair value of the ITCs is determined by applying the expected internal rate of return to the investor on this structure to the gross amount of the ITCs that may be claimed by the investor.
The ITCs are subject to recapture under the Code if the underlying solar energy system either ceases to be a qualifying property or undergoes a change in ownership within five years of its placed in service date. The recapture amount decreases by 20% on each anniversary of the PTO date. As the Company has an obligation to ensure the solar energy systems is in service and operational for a term of five years to avoid any recapture of the ITCs, the Company recognizes revenue as the recapture provisions lapse assuming the other aforementioned revenue recognition criteria have been met. The portion of monetized ITCs are reclassified to deferred revenue from lease pass-through financing obligation on the consolidated balance sheets when the leased systems are granted PTO. Subsequently, one-fifth of the monetized ITCs are recognized as revenue in the consolidated statements of operations on each anniversary of the solar energy systems’ PTO date over the following five years.
SREC revenue arises from the sale of environmental credits generated by solar energy systems. SREC revenue is recorded in operating leases and incentives revenue. We recognize revenue related to the sale of SRECs to the extent the cumulative value of delivered SRECs per contract exceeds any possible liquidated damages for non-delivery, if any.
The Company has determined that Customer Agreements are operating leases as opposed to capital leases pursuant to ASC 840, Leases. The initial lease term of Customer Agreements is 20 years. Since the estimated economic life of solar energy systems is estimated to be at least 35 years, the lease term is less than 75% of its estimated economic life. Additionally, the Company evaluated the following lease classification criteria: (i) whether there is a transfer of ownership or bargain purchase option at the end of the lease and (ii) whether the present value of minimum lease payments exceeds 90% of the fair value at lease inception and determined that these criteria were not met.
Pursuant to our early adoption of ASC 842, Leases ("ASC 842"), our Customer Agreements will no longer meet the criteria for lease accounting. Instead, we will account for our Customer Agreements pursuant to Topic 606. See discussion under “Recently Issued and Adopted Accounting Standards” below.
Solar energy systems and product sales
For solar energy systems sold to customers, the Company recognizes revenue when the solar energy system passes inspection by the authority having jurisdiction, provided all other revenue recognition criteria have been met. The Company’s installation projects are typically completed in a short period of time.
Product sales consist of solar panels, racking systems, inverters, other solar energy products sold to resellers and customer leads. Product sales revenue is recognized at the time when title is transferred, generally upon shipment. Shipping and handling fees charged to customers are included in net sales. Total shipping and handling fees charged to customers was $3.7 million for the year ended December 31, 2017 and $2.6 million for the years ended December 31, 2016 and 2015. Volume discounts given to customers are recorded as a reduction of revenue, since the Company does not receive goods or services in exchange for the discounts offered. Customer lead revenue, included in product sales, is recognized at the time the lead is delivered.
Taxes assessed by government authorities that are directly imposed on revenue producing transactions are excluded from product revenue.
About Revenue Disclosures
Revenue disclosures under ASC 606 explain how a company identifies performance obligations, allocates transaction prices, and determines when revenue is recognized. This section is essential for understanding whether reported revenue reflects genuine economic activity or aggressive accounting choices. Analysts examine the mix of point-in-time versus over-time recognition, which directly affects revenue timing and comparability.
Key signals: rising contract liabilities (deferred revenue) suggest strong future revenue visibility, while declining contract assets may indicate slowing project milestones. Watch for variable consideration estimates — rebates, returns, and performance bonuses that require management judgment. Significant changes in disaggregated revenue by geography or product line can reveal shifting business mix before it appears in headline numbers. Compare revenue growth against contract liability growth to assess sustainability, and scrutinize any changes in the timing of recognition that coincide with earnings pressure.
