Solar PV Electrical Engineering Services

Solar photovoltaic (PV) systems rely on more than just panels — they need well-designed electrical infrastructure that meets utility, code, and performance requirements.

At RJS Engineering, we provide electrical engineering design and consulting for commercial, industrial, and utility-scale solar PV projects. From rooftop arrays to solar farms, our team delivers safe, compliant, and constructible electrical designs that power solar success.

We’re based in Colorado and licensed in all 50 U.S. states.

Electrical Design for Grid-Tied Solar Systems

We support solar developers, EPC contractors (Engineering, Procurement, and Construction), and commercial property owners with the electrical engineering required for successful PV installations.

  • AC and DC electrical system design

  • Inverter selection and coordination

  • Load calculations and utility interconnection

  • Grounding, bonding, and arc flash protection

  • Panel schedules, conduit routing, and wire sizing

  • Switchgear, combiner box, and disconnect layouts

  • SCADA integration and real-time monitoring design

Commercial, Industrial & Utility-Scale Support

RJS Engineering designs electrical systems for a wide range of solar PV project types:

  • Commercial rooftop solar — office buildings, warehouses, retail centers

  • Carport and parking structure solar — with lighting and charging integration

  • Ground-mount and tracking systems — for agricultural and campus sites

  • Utility-scale solar farms — with medium-voltage connections and grid integration

  • Battery storage integration — DC-coupled or AC-coupled systems

Whether it’s a 250 kW system or a multi-MW deployment, we help solar developers build with confidence.

Utility Interconnection & Code Compliance

Solar systems must meet utility interconnection requirements and national electrical standards. We support these technical needs with:

  • Utility coordination and submission packages

  • NEC compliance (Article 690, 705, 710)

  • Voltage drop and fault current calculations

  • PV Rapid Shutdown (NEC 690.12) system design

  • Arc fault and ground fault protection engineering

SCADA Integration & Remote Monitoring

Our team integrates Supervisory Control and Data Acquisition (SCADA) into solar PV electrical systems — enabling monitoring of generation, inverter performance, breaker status, and alarms across multi-site portfolios.
