Include a separate Site and Roof Layout Plan for the Riverside County Assessor’s Office. ·Site Plan Provide a fully dimensional site plan showing property lines, all structures, and the location of the main electrical service, all photovoltaic inverters and disconnects, etc. ·Roof Plan Provide a roof plan showing the location of the photovoltaic panels and the required setbacks. Include all walkways to roof mounted equipment (including any roof mounted heating and air conditioning equipment, etc.). Roof plans should also identify the size and spacing of the existing roof framing members and the slope of the roof plus any required roof framing alterations needed. In addition, demonstrate the required clear path access pathways as required by the State Fire Marshal’s Office. You can find these clearances at: http://osfm.fire.ca.gov/training/pdf/photovoltaics/solarphotovoltaicguideline.pdf ·Attachment Details Provide an attachment detail demonstrating how the photovoltaic panels and array will be secured to the racking system and roof structure. ·Product Specifications and Literature Provide all manufacturers’ specifications on all inverters, solar panels, combiner and discon nect boxes and solar panel anchorage system to be used. ·Signage Specifications Provide a legend showing locations and wording of all required signs or placards at various photovoltaic system components. Standard Electrical Plan A standard generic electrical plan may be used for proposed solar installations of 30kW in size or smaller and can be downloaded within the City’s website. All submittals must be signed by a C -10 (Electrical Contractor) or C-46 (Solar Contractor) or licensed design professional. Electrical Plans should include the following: Location 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 inverter(s) and/or combiner box if used. Single line diagram of system . Specify grounding/bonding, conductor type and size, conduit type, size and number of conductors in each section of conduit. Page 3 of 4 If batteries are to be installed, include them in the diagram and show their locations and venting . Equipment cut sheets including inverters, modules, AC and DC disconnects, combiners and wind generators. Labeling of equipment as required by CEC, 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). Expedited Structural Criteria with Supporting Documentation A Structural Criteria Checklist can be downloaded at Department’s website or obtained in person. Projects not within the scope of this structural criteria may require a licensed design professional justification. For non-qualifying systems, provide structural drawings and calculations stamped and signed by a licensed designed professional along with the following information: The type of roof covering and the number of roof coverings installed . Type of roof framing, size of members and spacing. 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 manufacturer of the rack system, 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 . As a references, the Solar Structural Technical Appendix hyperlink is provided: http://www.opr.ca.gov/docs/Solar_Structural_Technical_Appendix.pdf Inspection Information Once a photovoltaic system permit has been issued and the system has been installed, it must be inspected before final approval is granted. Inspections are required to be scheduled twenty-four (24) hours in advance at: (760) 776- 6420 Monday through Friday (8AM to 4PM) Same day inspection will not be provided. Qualifying small rooftop PV systems will be inspected in one (1) site visit, if under 30 kilowatts. If PV system is over 30 kilowatts it will require a rough inspection after mounting system is installed. If the inspection does not pass, subsequent inspections will not conform to the one inspection policy per the California Solar Initiative AB2188. Permit holders must be prepared to show conformance with all technical requirements in the field at the time of inspection. The inspector will verify that the installation is in conformance with applicable code requirements and with the approved plans. An OSHA approved ladder must be provided by the contractor of record or property owner at the time of inspection. Here are some common points of inspection you should be prepared to show: Number of PV modules and model number match plans and specification sheets number match plans and specification sheets. Array conductors and components are installed in a neat and workman-like manner. PV array is properly grounded. Electrical boxes are accessible and connections are suitable for environment. Array is fastened and sealed according to attachment detail. Conductor’s ratings and sizes match plans. Appropriate signs are properly constructed, installed and displayed. Smoke detector and carbon monoxide alarms are required at final inspection. Page 4 of 4 QUICK TIPS FOR CONTRACTORS & PROPERTY OWNERS WHEN APPLYING FOR A SOLAR PERMIT: Permit applicants can save time and money by following these tips. Take time to review permit requirements of the local jurisdiction. Permitting rules and processes differ am ong different cities and counties. Understanding all local requirements will allow permit applicants to submit a complete and accurate permit application packet the first time. Contact the local electric utility early in the permitting process (solar PV installations). Local electric utilities have a completely separate approval process from the local jurisdiction’s permitting process. Some electric utilities may require that the solar project be reviewed before the local jurisdiction issues a building permit. Pursuing utility approval early in the permit process enables the solar PV system to become operational as soon as possible. Make sure that the solar installation that is built matches the submitted plans. The on-site inspector will verify that the installation aligns with proposed plans and any changes may require corrections and additional inspections.
