About this file

Written by GovTribe AI · Mar 13, 2026

This is a bid document and engineering design file for the Michigan Department of Transportation (MDOT) Southfield Bus Terminal Solar installation project, prepared by NOVA Consultants, Inc. The project involves the design and installation of a ground-mounted solar photovoltaic (PV) system with a capacity of 13.1 kilowatts direct current (kW DC) and 11.4 kilowatts alternating current (kW AC) at the MDOT Southfield facility located at 26991 Lahser Road, Southfield, Michigan 48033. The system will consist of 32 Jinko Solar photovoltaic modules rated at 410 watts each, one Fronius Primo 11.4 inverter, and associated electrical equipment including disconnects, grounding systems, and AC/DC connections. The engineering design progressed through multiple phases, with 50% design completion on June 1, 2022, 90% design completion on June 9, 2022, and the final bid documents issued on July 15, 2022. The design follows current Michigan Electrical Code, 2017 National Electrical Code (NEC), and all applicable local codes and standards.

The solar array utilizes a ground-mount configuration with a south-facing orientation (azimuth 180 degrees) and a 25-degree tilt angle, requiring site preparation including removal of specified trees, grass, topsoil, and sprinkler systems within the fenced array area. The system incorporates two parallel DC strings connecting to the single inverter, which includes residual current detection GFCI protection, arc fault protection certified to UL1699B, and anti-islanding protection compliant with UL1741 and IEEE 1547 standards. Electrical interconnection connects to the existing 200-ampere customer panel through a new junction box with a 60-ampere disconnect switch and fuse protection. The project requires installation of a 7-foot-high galvanized chain-link fence around the array area, a 3-gate access point at the northwest corner, grounding systems with multiple ground rods, and underground conduit routing from the array to the electrical room. Project file number is 591/22069.SAA, and project number is 22-03-1113.
