About this file
This bid document pertains to a solar photovoltaic (PV) system installation project for the Michigan Department of Transportation (MDOT) at the Benton Harbor Bus Terminal facility in Benton Harbor, Michigan. The project involves the design and installation of a 20.5 kilowatt direct current (kW DC) / 20.0 kW alternating current (AC) rooftop solar array system with associated electrical infrastructure. The system includes 50 Jinko Solar photovoltaic modules (model JKM 410M-72HL-V) rated at 410 watts each, two Fronius Primo 10.0-1/240 inverters, four electrical strings, optimizers, racking systems, and all necessary electrical connections and safety equipment. The project is designated as MDOT Project Number 22-03-1113 and File Number 591/22069.SAA, with design work progressing through 50 percent engineering (June 21, 2022), 90 percent engineering (July 6, 2022), and culminating in the bid phase (July 15, 2022). The scope of work includes removal of existing atrium structures, roof preparation and decking replacement, installation of PV modules on both flat and standing seam roof sections using specified racking systems, and installation of electrical equipment located beneath roof overhangs and on the southeast wall.
The electrical system is designed in accordance with the Michigan 2015 Building Code, Michigan Electrical Code, and the 2017 National Electrical Code (NEC). The system features two separate 10 kW inverters with a total nameplate capacity of 26.6 kW DC and 20.0 kW AC, achieving a DC-to-AC ratio of 1.13. Electrical components include a 240-volt/200-ampere panelboard (PB-A), disconnect switches, 125-ampere fuses, and junction boxes configured to connect to the existing DTE utility meter and customer panel. The design incorporates residual current detection GFCI protection, arc fault protection compliant with UL1699B standards, and anti-islanding protection meeting UL1741 and IEEE 1547 requirements. The system is engineered for a maximum DC voltage of 1000 volts and includes comprehensive grounding and bonding provisions per NEC Article 250. Engineering documents produced by NOVA Consultants, Inc. include site plans, electrical site layouts, one-line diagrams, PV module attachment details, and equipment elevation specifications to guide construction and installation of the complete solar system.
