Dominion Virginia Power installed more than 2,000 solar panels on the rooftop of Canon Virginia Inc.'s (CVI) Industrial Resource Technologies (IRT) facility in Gloucester, making it the largest roof solar system in Virginia. When operational, the panels at the Gloucester facility will generate more than 500 kW of electricity and will flow to the electric grid for use by Dominion Virginia Power customers. Construction started in December and the panels are expected to be fully installed and operational in early 2014.
