City and County of Denver Photo-voltaic Roof Installation – Denver, Colorado

General Contractor: MW Solar



Completion Date: 2010

Six Facility – 75-100kW (450kW DC) roof PV systems. Each of these facility roofs required different PV mounting solutions from flat ballasted, flat mechanically fastened, and standing seam metal roofs. The age of many of the buildings required special consideration with regard to the facility main electrical equipment. Bus re-certification was required for any service taps performs. A service tap was required when we could not make the necessary modifications to the gear to install breakers or fuses. When breakers were available, new coordination studies were necessary to comply with new NFPA arc-flash requirements. All work was performed during the normal operation of the facilities with no disruption for the occupants during the construction.
