Adam Farrell founded Silicon Solar when he was 15. It had a single product, a raw solar cell for use in educational kits, and was based in his bedroom. Today there are about 260 products, a busy Web site, sales are growing at about 10 percent annually, and the company is putting a large addition on a building it moved into last year.
Farrell owns 60 percent of the corporation. His older brother, Matt Farrell, a 24-year-old Cornell graduate, serves as vice president and owns the rest.
Adam Farrell expects to graduate in December 2006 with a degree in Applied Economics and Management from Cornell University.
