Utility Scale Solar Design & Engineering

Utility Scale Solar

SepiSolar designs and engineers utility scale solar PV and energy storage projects for developers, EPCs, utilities, independent power producers (IPPs), co-operative (co-op), and municipal utilities.

Utility developers, asset owners, and EPCs trust SepiSolar to design front-of-the-meter systems that maximize energy production and reduce PV system inefficiencies, labor, and equipment, and BOS costs.

SepiSolar’s utility independent engineering services and project reviews reduce the risk of project delays and financial losses due to technical, permitting, and interconnection errors.

SepiSolar’s utility scale solar design and engineering services include:

  • Preliminary designs and feasibility studies
  • Fixed tilt ground-mounted designs
  • Single-axis and dual-axis tracker designs
  • Utility solar designs using bifacial modules
  • Medium voltage utility system design
  • High voltage utility system design
  • Arc flash studies
  • Designs for central and string inverters
  • SCADA engineering
  • Technical due diligence for maximizing performance for utility power purchase agreements (PPAs)
  • Floatovoltaic (floating photovoltaic) systems
  • Interconnection design and feasibility studies
  • Energy storage modeling for utility applications, such as frequency regulation, voltage or reactive power support, system peak shaving, etc.
  • Interconnection application processing & troubleshooting
  • Utility infrastructure upgrade design & mitigation strategies
  • Real-time requirements database
  • Response letters/meetings
  • Preliminary single line diagrams with electrical engineering stamps


We submitted our RFP proposal to the utility today, and I wanted to thank SepiSolar for the excellent service you provided. Your ability to provide a detailed engineering design on a tight turnaround time was impressive. Your input helped us secure an updated utility scale solar design that met all of the RFP’s requirements. We look forward to working with SepiSolar again on future projects.”
