CRC b) Panels/modules installed on residential buildings shall be located no higher than 3 feet below the ridge in order to allow for fire department smoke ventilation operations. CRC (Per Town Municipal Code Section , the Building Division may permit solar panels to be mounted no higher than the ridge of the roof so long as the opposite side of the roof is accessible for fire ground activities. In addition, the Building Division may require that the design of the panel mounting assembly discourage the accumulation of flammable materials (such as pine needles). c) Ground mounted PV arrays shall be provided with a clear, brush-free area of 10 feet. 2 Indicate location of PV Installation (elevation drawing and roof plan, site plan drawing, etc.). For roof installed modules, define roof pitch as part of plans. If ground mount system, provide additional electrodes for Array Grounding in compliance with NEC (D). 3 Indicate location of readily accessible PV Disconnect location, located at first point of penetration of PV conductors. Indicate location of disconnects for all current-carrying conductors of PV source and equipment. (If proposing Listed PV Center, which address disconnects for entire dc system, provide appropriate listing data). 4 Indicate location of batteries (welding cables, marine, locomotive (DLO), and auto battery cables don t meet NEC).
