Due to variations in permitting requirements, we recommend you contact your local building authority to confirm permitting and installation requirements prior to ordering any equipment.

For critical installation details, please reference all installation manuals and local codes.

What are Electrical Wiring Diagrams?

Unbound Solar’s electrical wiring diagrams are CAD (computer-aided design) drawings which show the electrical sequence of all equipment in a system. An electrical diagram is an invaluable resource during the permitting process and system installation. An electrical diagram will be required when applying for your permit and for final inspection.


What Do Electrical Wiring Diagrams Cost?

In most cases, the cost of a standard electrical diagram is included in the price of our packaged systems. Our technical support department can customize these drawings for a small fee. Contact your sales technician for details and custom diagram pricing.

Ordering Standalone Diagrams

If you need to provide a wiring diagram to obtain a permit before purchasing your system, we can sell you the wiring diagram for a small fee. This fee is non-refundable, but it is credited toward your purchase should you choose to buy your system from us.

Why Do I Need An Electrical Wiring Diagram?

Quicker Permitting Process

Submit your permits earlier by having a diagram ready. Permitting can be the most time-consuming part of your project, so it helps to get started early.


Unbound Solar has extensive experience designing systems. The electrical wiring diagrams for our complete systems have been refined and perfected after working with thousands of homeowners and installers across the US and around the world. An accurate electrical diagram reduces the chance of re-submissions.

Our technical support department is factory-trained and experienced with all of the equipment we carry.

Fast Turnaround

Revisions and custom drawings are typically completed in a few business days. Some building departments may require a revision or two before approving your permit. We also offer revision support.

Fewer Errors During Installation

Wiring equipment incorrectly can be dangerous, costly and can void manufacturer warranties. An accurate wiring diagram leads to less downtime, fewer errors and an overall smoother installation process. You can rest easy knowing your system is wired safely and correctly.
