v.   Revenue recognition:
 
Revenues are recognized in accordance with ASC 606; revenue from contracts with customers is recognized when control of the promised goods or services is transferred to the customers, in an amount that the Company expects in exchange for those goods or services.
 
The Company’s products and services consist mainly of (i) power optimizers, (ii) inverters, (iii) batteries, (iv) a related cloud-based monitoring platform, (v) communication services, and (vi) warranty extension services.
 
The Company recognizes revenue under the core principle that transfer of control to the Company’s customers should be depicted in an amount reflecting the consideration the Company expects to receive in revenue.

 

In order to achieve this core principle, the Company applies the following five-step approach: (1) identify the contract with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract, and (5) recognize revenue when the performance obligation is satisfied.
 
(1)          Identify the contract with a customer
 
A contract is an agreement or purchase order between two or more parties that creates enforceable rights and obligations. In evaluating the contract, the Company analyzes the customer’s intent and ability to pay the amount of promised consideration (credit risk) and considers the probability of collecting substantially all of the consideration.
 
The Company determines whether collectability is reasonably assured on a customer-by-customer basis pursuant to its credit review policy. The Company typically sells to customers with whom it has a long-term business relationship and a history of successful collection. For a new customer, or when an existing customer substantially expands its commitments, the Company evaluates the customer’s financial position, the number of years the customer has been in business, the history of collection with the customer, and the customer’s ability to pay, and typically assigns a credit limit based on that review.
 
(2)          Identify the performance obligations in the contract
 
At a contract’s inception, the Company assesses the goods or services promised in a contract with a customer and identifies the performance obligations. The main performance obligations are the provisions of the following: providing of the Company’s products; cloud based monitoring services; extended warranty services and communication services. Depending on the shipping terms agreed with the customer, the Company may perform shipping and handling activities after the customer obtains control of the goods and revenue is recognized. The Company has elected to account for shipping and handling costs as activities to fulfill the promise to transfer the goods. As a result of this accounting policy election, the Company does not consider shipping and handling activities after the customer obtains control of the goods as promised services to its customers.
 
(3)          Determine the transaction price
 
The transaction price is the amount of consideration to which the Company is entitled in exchange for transferring promised goods or services to a customer, excluding amounts collected on behalf of third parties (e.g., sales tax and other indirect taxes). Generally, the Company does not provide price protection, stock rotation, and/or right of return. The Company determines the transaction price for all satisfied and unsatisfied performance obligations identified in the contract from contract inception to the beginning of the earliest period presented.
 
Rebates or discounts on goods or services are accounted for as variable consideration. Provisions for rebates, sales incentives and discounts to customers are accounted for as reductions in revenue in the same period the related sales are recorded.
 
Accrual for rebates for direct customers is presented net of trade receivables. Accrual for sale incentives related to non-direct customers is presented under accrued expenses and other current liabilities. The Company accrued $83,882 and $53,026 for rebates and sales incentives as of December 31, 2025 and December 31, 2024, respectively.
 
The Company has elected to apply the practical expedient to not evaluate payment terms of one year or less for the existence of a significant financing component.
 
When a contract provides a customer with payment terms of more than a year, the Company considers whether those terms create variability in the transaction price and whether a significant financing component exists.
 
As of December 31, 2025, the Company has not provided payment terms of more than a year.
 
The performance obligations that extend for a period greater than one year are those that include a financial component: (i) warranty extension services, (ii) cloud-based monitoring, and (iii) communication services. The Company recognizes financing component expenses in its consolidated statement of income (loss) in relation to advance payments for performance obligations that extend for a period greater than one year. These financing component expenses are reflected in the Company’s deferred revenues balance.
 
(4)          Allocate the transaction price to the performance obligations in the contract
 
The Company performs an allocation of the transaction price to each separate performance obligation, in proportion to their relative standalone selling prices. When a standalone selling price is not directly observable, the Company estimates it using the expected cost‑plus‑margin approach.
 
(5)          Recognize revenue when a performance obligation is satisfied
 
Revenue is recognized when or as performance obligations are satisfied by transferring control of a promised good or service to a customer. Control either transfers over time or at a point in time, which affects when revenue is recorded.
 
Revenues from sales of products are recognized based on the transfer of control, which includes but is not limited to, the agreed International Commercial terms, or “INCOTERMS”. Revenues related to cloud-based monitoring, extended warranty services, communication services and other services are recognized over time on a straight-line basis since these services have a consistent continuous pattern of transfer to a customer during the contract period.
 
Billed accounts receivable include all outstanding invoices to customers, as well as amounts allowed to be billed according to contractual billing terms with customers.
 
Deferred revenues and advances from customers consist of deferred cloud-based monitoring, extended warranty services, communication services, other services and advance payments received from customers for the Company’s products. Deferred revenues and advances from customers are classified as short-term and long-term deferred revenues and advances from customers based on the period in which revenues are expected to be recognized (see Note 15).

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.
