Quercus Trust’s David Gelbaum Takes Over as CEO of Solar Portfolio Company

David Gelbaum, has taken over as chief executive officer of Entech Solar, a Fort Worth, Texas-based developer of concentrating solar modules. Gelbaum knows the company well for being one of its major investor via his cleantech-focused venture capital fund Quercus Trust.

Gelbaum takes over for Frank Smith, who became Entech’s CEO in March 2008, reports Earth2Tech.

A year ago Quercus was the third-most active venture fund investing in cleantech. Earth2Tech reports that Quercus is invested in at least 48 renewable energy and cleantech companies.

Gelbaum and his Quercus fund are notoriously discreet and publicity -shy. Given that one can wonder if Gelbaum will be willing to take a more active roll commercializing Entech’s silicon photovoltaic cells.
