Commercial Solar Permit Design
Commercial PV projects require coordinated drawings that reflect the electrical service, utility interconnection, equipment, array construction, feeder routing, and jurisdictional requirements. Gemini Solar Design develops commercial solar permit packages for installers, electrical contractors, developers, and project partners across the United States.
Projects can range from multifamily and institutional rooftops to ground mounts, parking structures, and large commercial carports. You communicate directly with the designer performing the work.
Commercial project experience
- 120/208Y and 480V three-phase systems
- Commercial rooftops, ground mounts, parking garages, and carports
- String-inverter and commercial microinverter systems
- Multiple arrays, buildings, inverters, or combiner panels
- Long conductor and feeder runs
- Line-side and load-side interconnections
- Conductor schedules and voltage-drop documentation
- Service, switchgear, transformer, and distribution coordination
A coordinated permit package
Depending on scope, a commercial plan set may include cover information, site and array plans, equipment layouts, electrical single-line or three-line diagrams, stringing, conductor and conduit schedules, overcurrent protection, disconnecting means, voltage-drop information, grounding, required labels, construction details, specification sheets, and project-specific notes.
Commercial work often involves information from several parties. Gemini coordinates the drawings around the supplied architectural, civil, structural, electrical, equipment, and utility information, while identifying missing or conflicting inputs before they create avoidable redesign.
Representative complete projects
943 kW commercial solar carport
The public 24-page sample shows a large 480V carport project with Solectria string inverters, combiners, long feeder runs, conductor schedules, and utility interconnection details.
208Y Enphase apartment complex
The public 32-page sample covers a five-building rooftop design using Enphase IQ8H-3P microinverters and 120/208Y three-phase electrical service.
These examples demonstrate drawing depth and equipment coordination; they are not promises that every project has the same scope or page count.
Information to provide
Send the site address, utility, AHJ, proposed system size, service voltage and available electrical information, equipment list, array layout or usable-area information, one-line or existing facility drawings, structural or civil documents if available, feeder-routing assumptions, and any utility or jurisdiction comments already received.
Gemini reviews the material, identifies missing inputs, and confirms the design scope and pricing before work begins. If the project is still preliminary, describe the design goal and available documents so the next required information can be established.
Engineering and interconnection coordination
Commercial projects commonly require electrical or structural engineering review, calculations, or stamps. Gemini can secure and coordinate those services through appropriately registered professional engineers. Utility interconnection documentation, AHJ corrections, equipment revisions, and related electrical-design support can also be included when defined in the project scope.
Ongoing contractor support
Installers and electrical contractors can use Gemini for trial projects, ongoing production, overflow work, complicated PV/ESS systems, and correction support without adding another full-time designer.
