☀️ Renewable Energy Infrastructure

This project consisted of the complete AC and DC electrical infrastructure required to support a commercial rooftop solar installation.

​

AC Infrastructure

Power & Energy Tech Solutions completed a 350-foot underground trench installation to route utility and distribution feeders from the service equipment to the solar interconnection point. Scope included installation of the reinforced concrete equipment foundation, electrical raceways, and support systems required to house and protect the project equipment.

​

The AC side of the installation included:

• Utility disconnect installation

• CT cabinet installation

• Distribution panelboard installation

• Underground conduit systems and feeder infrastructure

• Equipment foundations and structural support systems

• Utility interconnection and coordination

• Final testing, commissioning, and energization

​

​

DC Infrastructure

The DC scope included installation and integration of the solar generation equipment from the rooftop array through the power conversion systems. Power & Energy Tech Solutions installed inverter systems, inverter combiner equipment, and the complete raceway network required to support the DC collection system.

​

The DC side of the installation included:

• Solar inverter installation

• Inverter combiner installation

• DC collection systems

• Cable trough systems

• EMT, PVC, and rooftop conduit infrastructure

• DC wiring and circuit terminations

• Equipment testing and commissioning

​

This project demonstrates our ability to deliver complete renewable energy infrastructure solutions, including civil coordination, underground electrical distribution, utility interconnection, AC/DC power systems, and final commissioning services.

This phase of the project focused on the installation of the complete solar array support system and photovoltaic module infrastructure. Power & Energy Tech Solutions performed the installation of all racking components, roof attachment systems, wire management systems, grounding infrastructure, and module placement required to construct the array in accordance with engineering specifications and manufacturer requirements.

​

The scope included layout verification, attachment point installation, blocking and structural support integration, rail assembly, and final panel placement across the rooftop system. Our team ensured all arrays maintained proper spacing, alignment, drainage clearances, and access pathways while meeting project-specific tilt requirements ranging from 5 to 15 degrees depending on array orientation and engineering design criteria.

​

Scope Included:

• Solar racking system installation

• Mechanical roof attachment installation

• Blocking and structural support integration

• Solar module (panel) installation and panelization

• Optimizer installation and management

• DC wire management systems

• Cable tray and rooftop raceway coordination

• Equipment bonding and grounding systems

• Array layout verification and alignment

• Tilt angle installation ranging from 5°–15°

• Manufacturer compliance verification

• Quality control inspections and commissioning support

Particular attention was given to wire management and grounding practices to ensure long-term reliability, ease of maintenance, and compliance with applicable electrical and utility standards. The completed installation provided a structurally sound, electrically compliant, and visually uniform solar array designed for maximum performance and long-term operational durability.

The Testing & Commissioning phase represents the final quality assurance process prior to system energization and turnover. Power & Energy Tech Solutions performs comprehensive electrical testing, verification, and commissioning procedures to ensure all equipment, conductors, and system components operate safely, reliably, and in accordance with project specifications.

​

Our commissioning process includes detailed inspections, documentation, and performance verification of both AC and DC electrical systems. Utilizing industry-standard testing equipment, our team verifies conductor integrity, insulation resistance, grounding continuity, equipment functionality, and overall system performance before final energization.

​

Testing & Commissioning Scope Included:

• Megger (Insulation Resistance) Testing

• Continuity Testing

• Grounding & Bonding Verification

• DC String Verification

• Open Circuit Voltage (VOC) Reports

• Insulation Resistance Reports

• Polarity Verification

• Conductor Integrity Testing

• Equipment Functional Testing

• Inverter Startup & Configuration

• Utility Interconnection Verification

• System Energization Support

• Final Commissioning Documentation

​

Throughout the commissioning process, detailed reports are generated to document system performance and compliance requirements. These reports provide owners, engineers, utilities, and project stakeholders with confirmation that the installation has been thoroughly tested and meets all applicable operational and safety standards.
