Do I Need a Permit for Installing a Tracker Solar Array?

Local Building Codes and Zoning Regulations

The first step in determining if you need a permit is to contact your local building department or permitting office. They will inform you about specific regulations and requirements for your area. For example, in California, the California Building Code (CBC) and the California Electrical Code (CEC) govern solar installations, including trackers. If your project exceeds 10 kW, a permit is likely required. Make sure to also check with your local planning department to ensure compliance with zoning regulations.

System Requirements and Permitting

When submitting a permit application, you’ll need to provide detailed information about your tracker solar array, including its size, type, and location. This may include schematics, electrical diagrams, and structural calculations. Your local permitting office may also require documentation of the tracker’s compliance with local building codes, such as the International Building Code (IBC) and the International Residential Code (IRC). For example, if you’re using a single-axis tracker, you may need to demonstrate that it’s designed to withstand wind loads of at least 120 mph.

Permitting Costs and Processing Times

The cost of a permit can vary widely depending on your location and the complexity of your project. In some areas, the permitting fee may be based on the system’s size, while in others it may be a flat fee. Processing times can also vary, but typically range from a few weeks to several months. To minimize delays, be sure to submit a complete and accurate permit application package, including all required documentation and plans. It’s also a good idea to work with a solar installer who is familiar with local permitting requirements and can help guide you through the process.
