Dovetail Solar and Wind president Alan Frasz stands before one of the 14 large solar trackers the company is building for Case Western Reserve University on the site where Mt. Sinai Hospital once stood. The Sun Farm is part of CWRU's $5 million Solar Durability and Lifetime Extension Center headed by Roger French. The center is investigating how solar panels age. Dovetail in six years has grown from a quarter-million dollars in annual sales to nearly $10 million, and could double that by 2013.
