About this file
This is an As-Built document for a 64.86 kW Grid-Tie Photovoltaic System installed at the Bluffdale City Hall, located at 2222 West 14400 South in Bluffdale, Utah. The project was completed by Gardner Engineering Alternative Energy Services, a NABCEP-certified PV Installation Professional firm. The solar installation consists of 155 REC-345-TP-2S-72 345-watt silver solar modules and 105 IQ6-Plus Enphase 240-watt micro-inverters, strategically arranged across multiple roof sections with detailed electrical routing and junction box configurations. The as-built documentation was finalized on February 1, 2019, and includes comprehensive technical drawings showing site plans, ballast distribution, branch layouts, and electrical roof details.
The system is designed with multiple string configurations, utilizing various micro-inverter arrangements across different roof sections, with a total combined AC inverter output of approximately 120.81 amps. The electrical infrastructure includes existing RMP (Rocky Mountain Power) interconnection, with connections to a main switchboard in electrical room 105 and roof-mounted 125-amp panels. The documentation meticulously details bonding, grounding, wire specifications (including copper wire and THWN ground types), and the precise placement of electrical components. The project demonstrates a comprehensive approach to municipal solar infrastructure, integrating renewable energy technology into the existing city hall facility with detailed professional engineering documentation.
