Going solar is one of the best decisions you can make for your home and the environment. However, navigating the complex process of solar permitting, services, and inspections can be overwhelming. Whether you’re a first-time installer or a seasoned DIYer, understanding the steps involved can save you time, money, and frustration.
In this guide, we’ll walk you through everything you need to know about solar permitting, from application forms to final inspections. By the end of this article, you’ll have a clearer idea of what to expect, how to prepare, and how to streamline the process to get your solar system up and running as efficiently as possible.
What Is Solar Permitting?
Before you can install your solar panels, you’ll need to apply for solar permitting. This process ensures your system is safe, compliant with local building codes, and properly integrated with the utility grid. Permitting typically involves two main approvals: one from your local building authority and another from your electric company to allow interconnection with the grid.
The Step-by-Step Process for Solar Permitting
Getting your solar system permitted can feel like navigating a maze, but it doesn’t have to be stressful. Here’s a breakdown of each key step:
Step 1: System Design & Line-Item Quote
The first step in solar permitting begins with designing your system. This is where the planning phase comes into play. You’ll need to partner with a solar design technician who will assess your energy needs, local climate, and specific goals for going solar.
Key components for system design:
- Energy usage: A detailed review of your current energy consumption.
- Roof size & orientation: A solar tech will also evaluate your roof’s suitability for solar panels.
- System size: This is determined based on your energy needs and the amount of sunlight your area receives.
Once the system is designed, the technician will provide a line-item quote that includes all the necessary components for your installation, such as inverters, solar panels, and mounting hardware. This quote is a crucial part of your permit application.
Step 2: Apply for the Interconnection Permit
The next step is to apply for an interconnection agreement with your utility company. This permit authorizes you to connect your solar system to the grid, allowing you to generate and send power back to your local electric grid.
What to include in the interconnection permit application:
- System components: Specifications for your solar panels, inverters, and other hardware.
- Site map: A detailed map of your property showing the location of your solar system and electrical components.
- Wiring diagrams: A schematic that details the wiring configuration of your system.
- Capacity ratings: Information on the power capacity of your solar panels and inverter.
Most utility companies will have an online application form, but if you can’t find one, it’s always a good idea to contact them directly.
Step 3: Submit for a Building Permit
Your solar permitting process will also require you to file for a building permit with your local authority having jurisdiction (AHJ), usually your city or county planning office. This step ensures that your system will be installed according to building codes and local safety standards.
Building permit considerations:
- Roof strength: If you’re installing a roof-mounted system, your AHJ will want to ensure that your roof can support the weight of the solar panels.
- Structural integrity: For ground-mounted systems, the AHJ will verify the foundation and structure are sound.
- Fire safety: The AHJ will assess any fire safety hazards, especially around wiring and panels.
Most modern homes can pass this inspection without issue, but if your home is older or has a roof in poor condition, repairs may be necessary. If you’re unsure, you can schedule a pre-inspection with an engineer to assess the roof’s suitability.
Step 4: Fill Out and Submit All Forms
Once you’ve gathered your design documents, you can start filling out both the interconnection and building permit forms. Make sure you include the following information:
- Product spec sheets for all equipment used.
- Site map or plot plan of your property.
- Solar panel wiring diagrams.
- Engineering certifications for the panels, racking, and mounting hardware.
This process can be time-consuming as applications often exceed 10 pages. If you prefer, third-party solar permit services like Gemini Solar Design or Solar Permit Services can help you prepare and submit the necessary documents for a flat fee. These services are worth considering if you’re feeling overwhelmed.
Step 5: Approval Process
After submitting your application, the local building authority and utility company will review your submission. If they approve your permit, you’ll receive official documentation allowing you to install your solar system. If your application is rejected, they’ll notify you of any issues that need fixing, and you’ll need to revise and resubmit your permit.
Pro tip: Double-check all your paperwork before submission. Small errors can cause significant delays in the approval process.
Step 6: Final Inspection
After your solar system is installed, you’ll need to schedule a final inspection with both the AHJ and utility company. This step is necessary to confirm that your system meets all codes and safety standards.
The inspection typically involves:
- Electrical checks: Ensuring that all wiring and connections are secure and meet code.
- Structural review: Verifying that the mounting system is properly installed.
- Safety standards: Checking that the system includes fire safety placards, appropriate signage, and clear access points.
Once everything passes, you’ll receive approval from the utility company to begin using your solar system. At this point, you can flip the switch and start enjoying the power of solar energy!

FAQs
How long does solar permitting take?
The permitting process can take anywhere from a few days to several weeks, depending on your local jurisdiction’s workload and the complexity of your system. While it’s tempting to rush, taking your time with the paperwork can help avoid delays later on.
How much do solar permits cost?
The cost of solar permitting can vary widely. Typically, permits will cost a few hundred dollars, but this depends on your city or county. Make sure to inquire about fees when you submit your permit applications.
Do I need a permit for off-grid solar?
Yes, even if you’re not connecting to the grid, you will still need a permit. The building permit ensures that your off-grid system is safe, structurally sound, and compliant with local regulations. For off-grid systems, you won’t need an interconnection agreement, but your system will still be subject to inspection.
Can I handle the permitting process myself?
While you can submit your permits, many find it helpful to hire third-party services to handle the paperwork. This can save time and reduce the risk of mistakes, especially for those unfamiliar with the permitting process.
Conclusion
Getting your solar system permitted can be a lengthy process, but it’s a crucial part of ensuring the safety, effectiveness, and compliance of your system. From system design to final inspection, solar permitting is an essential step in making sure your solar installation goes smoothly. Remember, while the paperwork can be overwhelming, it’s well worth the effort to ensure that your system functions properly and adheres to local regulations.
