Solar PV Interconnection Single Line Diagram Examples

From a 10 kW rooftop array to a 1 MW utility-scale plant, these solar PV interconnection single line diagrams show the AC and DC paths, protection, and metering needed to connect photovoltaic systems safely to the grid. The gallery covers load-side and supply-side interconnections, as well as PV-plus-storage designs for critical facilities.

How to

How to use a single‑line diagram template.

  1. 01Open the solar PV interconnection template

    Start from a pre-built SLD scene with a PV array, inverter, AC disconnect, and point of interconnection.

  2. 02Set the system configuration

    Choose load-side or supply-side interconnection and add components such as battery storage, transformers, or generation meters.

  3. 03Adjust ratings and labels

    Enter conductor sizes, breaker ratings, and equipment names so the diagram reflects your specific installation.

  4. 04Review the one-line path

    Check the flow from PV modules through inverter to the service connection and confirm all required disconnects are present.

  5. 05Export for your application

    Download the diagram as PDF or PNG for permits, interconnection requests, or as-built documentation.

FAQ

Questions about single‑line diagram templates

What is a solar PV interconnection single line diagram?

It is a simplified electrical drawing that shows the main power components, connections, and protection devices from the solar PV system to the utility point of interconnection on a single line.

What is the difference between load-side and supply-side interconnection?

Load-side interconnection connects the PV system through a breaker on the existing service panel, while supply-side interconnection taps ahead of the main service disconnect, often requiring a dedicated service entrance section.

Do I need a single line diagram to apply for solar interconnection?

Most utilities and many local permitting authorities require an SLD as part of the interconnection application or permit package to verify that the design meets electrical and safety standards.

Can I include battery storage in the same single line diagram?

Yes, battery storage can be shown on the same SLD by adding the battery inverter, DC or AC coupling, and associated disconnects and metering relative to the point of interconnection.

What size solar systems can these diagrams cover?

The examples span from small residential systems around 10 kW up to utility-scale projects of 1 MW and larger, so you can adapt the symbols and layout to different voltage levels and interconnection types.
