(1) Building integrated means: Photovoltaic cells, modules, panels, or arrays that are integrated into the outer surface or structure of a building and serve as the outer protective surface of that building, such as the roof, skylights, windows, or facades. 004 Installation.
(2) Support structure or foundation. For the purposes of this section, those portions of the structure support or foundation that are exclusively mechanical and are not part of a bonding or grounding path will not be considered part of the photovoltaic system as defined by this section. Such structural support or foundation may be done by the owner, registered general contractor, or licensed electrical contractor without electrical permit or inspection.
(3) A photovoltaic system design review must be provided at the time of the first inspection.
(4) For utility interactive systems, persons making interconnections between solar photovoltaic system and the utility distribution network must consult the serving utility and are required to meet all additional utility standards.
(5) The entity placing a building integrated cell, module, panel, or array is not subject to the requirements for electrical inspection, licensing, or certification so long as the work is limited to the placement and securing of the device and an electrical work permit has been previously obtained for the electrical work related to the equipment by an entity authorized to do that electrical work.
(6) All electrical work, including wiring installation, terminations, etc., necessary to complete the electrical installations must be completed by the entity authorized to do the electrical work (i.e., owner or appropriate electrical contractor). 007 Maximum voltage.
(7) The open-circuit voltage temperature coefficients supplied in the instructions of listed photovoltaic modules will be used to determine the maximum direct current photovoltaic system voltage. Otherwise the voltage will be calculated using Table 690.7 of the NEC. For the purposes of this calculation, a temperature correction factor of 1.25 will be used unless another factor can be justified and is approved by the authority having jurisdiction. 053 Direct-current photovoltaic power source.
(8) All photovoltaic equipment and disconnecting means must be permanently identified as to their purpose, maximum voltages, and type of current within the system with an identification plate. All photovoltaic circuits must be identified at each overcurrent protection device(s) and panel directory(ies).
(9) Required "WARNING
" labels as specified by NEC 690 are required to be an identification plate on or immediately adjacent to the pertinent equipment.
