The City of Palm Desert has implemented an expedited solar permitting process for solar photovoltaic systems 20kW AC
or less. This checklist is required to be attached to all solar permits 20kW or less and the below requirements in
compliance at the time of inspection.
*HQHUDO5HTXLUHPHQWV
•The photovoltaic system size is 20kW AC CEC rating or less.
•The solar array is roof-mounted on a one- or two-family dwelling unit or permitted accessory structure. The roof
structure must be sound with no more that two (2) roof covering materials.
•The photovoltaic system is utility interactive (Battery storage is allowed).
•Ground mounted PV system are not eligible and require a plan review.
Planning Department Requirements
•Existing Main Service Panel Doubling, e.g. 100 to 200 OR 125 to 225. PLANNING WILL NEED TO REVIEW.
•Maximum height of “tilted” panels shall not exceed eighteen (18) inches.
•All wires shall be strapped to the modules/racking system. No loose or hanging wires are permitted.
•The racking system shall match the module frame and shall be a color compatible with the architectural character
of the home or building.
•Modules shall be flush with one another and gaps between panels shall be minimized.
•Screening of panels is not required. Any screening material proposed shall be compatible with the architectural
character of the home of building.
Electrical Requirements
•No more than four photovoltaic module strings are connected to each Maximum Power Point Tracking
(MPPT) input where source circuit fusing is included in the inverter:
No more than two strings per MPPT input where source circuit fusing is not included
Fuses (if needed) are rated to the series fuse rating of the PV module
No more than one non-inverter-integrated DC combiner is utilized per inverter
•For central inverter systems: No more than two inverters are utilized.
•The PV system is connected to the load side of the utility distribution equipment.
•Load calculations are required when de-rating an Main Service or Sub Panel.
•A Solar PV Standard Plan (California Solar Permitting Guide) and supporting documentation (if applicable).
Structural Requirements
•A completed Structural Criteria and/or supporting documentation is attached to the plan set.
•All ballast designed systems require a formal plan review with supporting structural design and justification.
•An inspector may require to sample roof attachment hardware for depth and proper materials.
Fire Safety Requirements
•Clear access pathways provided.
•Fire classification photovoltaic system is provided.
•All required marking and labels are provided.
•A diagram of the roof layout of electrical panels, modules, clear access pathways and approximate locations of
electrical disconnecting means and roof access points are completed and attached.
I understand and affirm that the above information regarding the solar photovoltaic is true and accurate. If during the inspection
process any deviation in this scope will result in stop work and full plan review. In the event a project requires supplemental plan
reviews, a plan review fee of $168.00 per hour (with one-half hour minimum) will be collected from the applicant.
