    Getting your solar permit in California for solar installations can be one of the most difficult and tedious parts of the whole process. That’s why we at Avila Solar have created several different solar permit and design services so you can choose the right option for your project and benefit from our experts’ experience and knowledge. In this article, we’ll lay out the solar permitting process to help you better understand how to obtain a solar permit in California.

    Utility Interconnection Requirements

    If you are installing a grid-tied system, the California utility company that manages your local grid will need to know that you are installing a solar energy system and they will most likely want to inspect it for themselves. They will also certify that the equipment you are using is properly certified so it won’t cause any safety hazards or power draw issues.

    The public utilities will also need to ensure that the power infrastructure can handle the added power that will be generated by your solar energy system since areas can become too saturated if a lot of people install solar energy systems in a small area and the grid isn’t built to handle that much excess energy.

    Applications for utility interconnection can be anywhere from 3-10 pages and will ask for information like the location of your existing utility meter and electrical panel, where you plan to install the solar panel array, how many solar panels and inverters will be in your system, what model of panels and inverters you plan to use, and the capacity rating for everything in your system.

    Local Building Department Requirements

    Additionally, you will need to coordinate with your local Authority Having Jurisdiction (AHJ). Your AHJ might be a City and County Building Department depending on your exact location. These requirements vary, but the most common one is that you may need to have an engineer certify that your roof is suitable for a solar energy system and that it can bear the additional weight of a panel array.

    CA Solar Permit Required Checklist

    In general, your building permit checklist will look something like this:

    • Prepare your building and electrical permit applications.
    • Prepare construction documents that are drawn to scale.
      • These should include a site plan that has the lot and building dimensions, the array-to-total roof ratio, and the location and dimensions of the array and all fire access pathways.
      • Also include all of the manufacturers’ supporting documentation for all the components of your solar energy system.
      • These construction documents also need to demonstrate that the planned rack or mounting system will be able to withstand snow, seismic, and other forces as outlined by the structural building codes for your area.

    California Expedited Solar Permitting

    If your PV installation is small-scale and residential, it is most likely eligible for an expedited permit process. This is designed to simplify the structural and electrical review, which reduces the need for detailed engineering inspections and minimizes delays in the process, since most PV systems less than 15kW are generally quite similar.

    You can expedite your solar permits both on the approving end as well as on your end, with an expedited permit application package from Avila Solar. For an additional fee, we can have your permit application documents ready to go in just two business days.

    To begin, please contact us to see if we are able to work in your jurisdiction. Currently, we are only able to work with online permitting departments and utilities for the time being. 

    Problems With the Existing Process of Solar Permitting

    The main barrier for people considering adding a PV system to their home is the permit process, because the requirements and steps are so different state to state, and even between neighboring cities. The processes are often complex and inconsistent, which can confuse people enough that they scrap the entire idea.

    Your AHJ, the local utility company, and even your homeowners’ association can have different sets of requirements and restrictions that make it nearly impossible to navigate the process. On top of that, there are often unpredictable fees and long wait times for permit approvals.

    Luckily, that’s where we at Avila Solar come in. We will handle your solar permitting process from start to finish and assist you with preparing documents, finding and dealing with your local AHJ, and expediting the process as much as possible. Don’t need a full permitting service? We also offer drafting services for wanting just a solar plan set.

    Starting at $225, our solar plan sets are popular among California solar installers. With a 2-day turnaround and reliable customer service you can count on our drafting specialist to speed up your installing process and reduce your overheard (and a headache!)

    Reduce Your 'Soft Costs'

    Soft costs’ are the process-related costs of a solar energy system installation, whereas ‘hard costs’ are the expenses of the equipment itself, such as purchasing the solar panels and inverters and so forth.

    The soft costs generally include items like permitting and inspection fees, grid interconnection costs, installation expenses, and financing. These types of expenses can add up quickly, especially when you attempt to do everything on your own. By offloading your drafting services to us, we can save you money by keeping your plan set prices fixed and low. 

    Our drafting specialist at Avila Solar know that not every solar project is the same. We work with hundreds of projects each month all across the United States so we understand the importance accuracy in order to stay within your budget.
