SolarApp+ for Residential Solar Installers
Before applying for an automated solar plan review and solar permit, projects must follow certain requirements. At this time, SolarAPP+ is designed to provide a code-compliance check for the majority of residential, roof-mounted, retrofit photovoltaic systems. To see which systems are eligible, please refer to the Eligibility Checklist. Only projects that conform to this list are eligible to use the automated SolarAPP+ portal for instant permitting.
A City of Gilroy Building Permit is required to install a rooftop solar PV system with a maximum power output of 10 kW or less. These permits do not require a separate planning or fire services review and approval. All roof-mounted solar installations must meet California State Fire Marshall requirements; this information is verified through building plan checks and building inspections.
- Manufacturer label and listing specifications should be provided for all array components (e.g. PV Panel Module, Inverter, Rack, Mounting, Power Optimizer, Rapid Shutdown, Battery, etc.).
- Demonstrate compliance with the Eligibility Checklist for Expedited Solar Photovoltaic Permitting (PDF: 140 kb)
- A completed electrical plan and single line electrical diagram must be provided. Standard Electrical Plan templates (see PV Toolkit Document #3 Central Inverter, page 26 or PV Toolkit Document #4 for Microinverter, page 38 as applicable) may be used for proposed solar installations 10 kW in size or smaller.
- If standard electrical plans are not provided for use, an electrical plan must be submitted that includes the following.
- Locations of main service or utility disconnect.
- Total number of modules, number of modules per string, and the total number of strings.
- Make and model of the inverter(s) and/or combiner box if used.
- One‐line diagram of the system.
- Specify grounding/bonding, conductor type and size, conduit type and size, and the number of conductors in each section of conduit.
- If batteries are to be installed, include them in the diagram and show their locations and venting.
- Location and wording for permanent labeling of equipment as required by CA Electrical Code, Sections 690 and 705.
- Site diagram showing the arrangement of panels on the roof or ground, north arrow, lot dimensions, and the distance from property lines to adjacent buildings/structures (existing and proposed).
- A roof plan showing roof layout, PV panels, and the following fire safety items: approximate location of the roof access point, location of code-compliant access pathways, PV system fire classification, and the locations of all required labels and markings. Examples of clear path access pathways are available in the State Fire Marshal Solar PV Installation Guide (PDF).
- A completed Structural Criteria for Expedited Solar PV Permitting form (Toolkit Document #5) along with required documentation.
- For non-qualifying systems, provide structural drawings and calculations stamped and signed by a California licensed Civil or Structural Engineer, along with the following information.
- The type of roof covering, and the number of roof coverings installed
- Type of roof framing, size of members, spacing, and maximum rafter spans.
- Weight of panels, support locations, and method of attachment
- Framing plan and details for any work necessary to strengthen the existing roof structure
- Site‐specific structural calculations
- Where an approved racking system is used, provide documentation showing the manufacture of the rack system, the maximum allowable weight the system can support, attachment method to the roof or ground, and product evaluation information or structural design for the rack system
- A completed Smoke Detector & Carbon Monoxide Self-Certification Form (PDF). The California Residential Code requires that smoke and carbon monoxide alarms be provided in all residential buildings where a building permit is issued for additions, alterations, or repairs with a valuation exceeding $1,000.
- A completed Water Conserving Plumbing Fixture Self Verification Form (PDF). In order to grant final approval on your permit, it is necessary to verify the replacement of non-compliant plumbing fixtures with compliant fixtures. This form provides the property owner the ability to self-verify compliant fixtures when work for which the permit is issued does not allow convenient access to the interior of the dwelling (e.g., re-roof, electrical service upgrade, or other exterior work).
