Segment Reporting [Abstract]

Segment information

18. Segment information

We currently operate in one business segment, the manufacturing and servicing of solar tracker systems. We consider our segment results to be the same as our consolidated results and our segment accounting policies to be the same as those described in Note 2, "Summary of significant accounting policies" above.

We report our revenue based on the products and services we provide. Product revenue is derived from the sale of solar tracker systems and customized components for those systems, individual part sales for certain specific transactions and the sale of term-based software licenses. Service revenue includes revenue from shipping and handling services, engineering consulting and pile testing services, our subscription-based enterprise licensing model and maintenance and support services in connection with the term-based software licenses.

Based on certain significant period cost information regularly provided to our Chief Operating Decision Maker, following is a reconciliation of such costs to our consolidated net loss for the three and six months ended June 30, 2025 and 2024:
