Solar System Design & Engineering

Design is where a solar project is won or lost. Undersized conductors, an overloaded panel or a permit package that keeps getting rejected all cost time and money long before anyone climbs a roof. Our background is electrical engineering, and it shows in the drawings.

We produce complete electrical design packages: array layout and string sizing, inverter and conductor selection, overcurrent protection, panel schedules, single line diagrams and labeling. We then carry that package through the permit process with your jurisdiction and through interconnection with your utility.

What’s included

  • Complete electrical design and single line diagrams
  • Array layout, string sizing and inverter selection
  • Structural and load calculations for the mounting
  • Permit packages prepared for your jurisdiction
  • Utility interconnection applications and follow up
  • Design only engagements available

This work also stands on its own. If you already have equipment or another contractor in place, we can provide the design and permitting package alone.
