Photovoltaic (PV) power systems involving ''premises wiring'' usually must meet the requirements of the National Electric Code (NEC). This is often difficult or uneconomic because PV standard design practices, and in some cases, the required dc-rated hardware, are not readily available. This paper focuses on problems in applying the NEC to PV system design and installation. Generic design requirements are discussed, including dc collection, ground-fault detection, disconnection and switching. A dc-service panel concept is introduced as a practical approach to meeting both NEC and functional design requirements. A sample design, and economic assessment are provided to support this concept. 5 refs., 6 figs., 2 tabs.
