Van’t Hof is a principal at US-based Oakland Capital Solutions, the financing and advisory arm of Oakland Capital Partners, and has been the chair of the SEIA board since January 2011.
“Darren is the right choice to serve as interim CEO because he brings continuity, consistency and a deep understanding of SEIA’s work,” said Elizabeth Reicherts, global head of government affairs for SolarEdge Technologies and the chair of SEIA’s executive search committee.
“Darren is a trusted leader, and we’re confident his steady hand will ensure SEIA continues to deliver strong advocacy and meaningful progress for its members.”
The news follows a number of positive milestones for the US solar sector, which has endured a challenging federal policy environment in 2025. SEIA notes that the US solar and storage industry is now worth US$70 billion, and announced this week that the sector added 11.7GW of new operational solar capacity in the third quarter of this year, the third-most capacity to be added to the US market on record.
