Inspection Guidelines General • Customer / installer shall provide approved plans on site for inspector. • Photovoltaic module number and location of installation must match approved site plan. Note: Revisions to the PV panel layout shall be submitted to the Building & Safety counter for review prior to final inspection. Additional fees may be charged. • Customer / installer shall provide access to all areas needed for inspection. • Roof mounted panels: Installer shall provide a proper and secured ladder(s) to access all areas. • In house: If wiring in attic and/or garage area, the customer/installer shall ensure access to these areas. Roof Access and Pathways • Verify minimum 18-in to 36-in clearance from arrays to ridge and edge of roof. (CRC R329.6.1) o PV arrays occupying no more than 33% of the roof area (plan view),shall have no less than 18” of clear setback required on both sides of a horizontal ridge. (CRC R329.6.2) • Verify all structural supports are properly installed and sealed per listing. • Verify all metallic raceways, J-boxes, supports and modules are properly labeled and grounded in accordance with product listings.
