solar permit costs

Home and business owners typically want the benefits of solar power but without the hassle of navigating solar permitting red tape. Therefore, solar energy installers usually handle the solar permitting process on their customer's behalf. Although many Authorities Having Jurisdiction (AHJs) have made considerable progress in simplifying the solar permitting process, it can burden contractors. Therefore, it's critical to reduce solar permit costs and streamline the process to ensure your residential and commercial projects are profitable.


Solar permitting issues can often delay projects, reflecting poorly on solar contractors, even if they aren't at fault. Likewise, they can make it difficult for you to schedule installations and properly manage workflow. Read on to gain valuable insights from our decade of solar permitting experience that can save time and money while providing excellent customer service.


What Is a Solar Permit?

Solar permits are official approvals granted by local AHJs that allow the installation of solar energy systems on residential or commercial properties. These permits typically include building and electrical permits, ensuring the solar installation meets all relevant codes and standards. The process involves submitting detailed plans and specifications of the proposed system for review by local building departments. In some cases, it also includes a zoning and structural review.


Importance of Residential Solar Permits

Solar permits are crucial in maintaining safety, ensuring all installations adhere to local building and electrical codes. By requiring solar panel permits, local authorities can verify that the system is designed and installed correctly, reducing the risk of electrical faults, structural failures, or fire hazards. This compliance helps protect both the property owner and the broader community.


Also, solar permits ensure that installations meet quality standards, which can enhance system performance and lifespan. Adherence to codes and standards ensures safety and boosts the reliability and efficiency of the solar energy system, contributing to the overall effectiveness of renewable energy adoption.


Overview of the Typical Residential Solar Permitting Process

The typical solar photovoltaic (PV) permitting process involves several steps:


1. Pre-Application Research: Homeowners or installers research local permitting requirements, which can vary by jurisdiction. This includes understanding necessary documents, fees, and any specific local codes that must be adhered to.


2. Solar Permit Application Submission: Detailed plans and specifications of the solar PV system are prepared and submitted to the local permitting authority. This usually includes site plans, electrical diagrams, and structural calculations.

3. Solar Plan Review: The submitted documents are reviewed by building and electrical inspectors to ensure compliance with local codes and standards. If any issues are identified, this step may involve revisions and resubmissions.


4. Solar PV Permit Issued: Once the solar plan sets are approved, the PV permits are issued. The installation can then proceed in accordance with the approved plans.


5. Solar System Inspections: During and after installation, inspections are conducted to verify that the work complies with the approved plans and local codes. This may involve multiple inspections, such as a rough inspection before panels are installed and a final inspection once the system is operational. However, some AHJs only require one solar site inspection.


6. Final Solar Permit Approval: After passing inspection, the AHJ grants final approval, and the system can be officially commissioned and connected to the grid.


Factors Impacting Solar Permit Costs

The cost of obtaining permits for solar panel installations can vary widely depending on several key factors:


Solar System Location: Solar permit costs can differ significantly depending on the city, county, or state where the installation is taking place. Local governments set their own fee structures, and some areas may have higher fees due to more complex regulatory requirements or higher administrative costs. For instance, urban areas often have higher permit fees than rural locations.


PV System Size and Type: The size of the solar panel system being installed plays a crucial role in determining solar permit costs. Larger systems typically require more extensive review processes, which can increase the permit fees. Additionally, the type of system (residential vs. commercial) can influence costs, with commercial installations often incurring higher fees due to their complexity and scale.


solar permitting ground mount

Ground Mount vs. Rooftop Solar: Solar permitting costs may be higher for ground-mounted PV systems because some municipalities require a zoning permit for such systems. Also, plan sets for ground-mount systems are more likely to need engineering reviews and stamps. This may also require additional paperwork to provide documentation that the proposed system complies with local zoning regulations and structural requirements.


Local Regulations and Inspection Requirements: Different municipalities have varying regulations and inspection requirements that can affect the cost. Some areas may require multiple inspections throughout the installation process, adding to the total permit cost. Furthermore, stringent local codes or additional requirements for structural engineering reports and electrical assessments can increase expenses.


Solar Permit Application Complexity: The complexity of the PV permit application process itself can influence costs. If the application requires detailed documentation, professional drawings, or specific technical specifications, the cost can be higher due to the need for specialized services to complete the application accurately, such as solar engineering stamps and reviews.


Expedited Solar Permit Processing Fees: Sometimes, you may opt for expedited processing to fast-track the solar permit approval process. This often comes with an additional fee, increasing your total solar permit costs.


Strategies to Reduce Solar Permit Costs

Although solar permitting expenses can increase your soft costs, there are several ways to minimize them while promoting solar permitting success.


Streamline the Solar Permit Application Process

Solar companies should start researching local permit requirements early in the planning stage to streamline the permit application process. Gathering all necessary documentation, such as site plans, system designs, and electrical diagrams, in advance can prevent delays. Also, leveraging online solar permitting systems where available can expedite the process and save time.


Ensure Accurate Documentation & Solar Plan Sets

Thorough planning and accurate documentation are crucial for a smooth permitting process. Ensuring all solar drawings and plan sets meet local building and safety codes can avoid costly revisions and resubmissions. Detailed and precise documentation helps pass solar inspections quickly and efficiently, reducing the likelihood of project delays and additional costs.
