UL 1703 Certification

UL 1703 covers flat-plate photovoltaic modules and panels that comply with the National Electric Code (NEC), OSHA, the National Fire Prevention Association, and will be readily accepted by local inspectors. The UL 1703 standard also means that the performance of the panels has been tested and has been found to perform to at least 90% or more of the manufacturers stated power rating. UL 1703 is scheduled to eventually be superseded by UL IEC 61730.

1.1 These requirements cover flat-plate photovoltaic modules and panels intended for installation on or integral with buildings, or to be freestanding (that is, not attached to buildings), in accordance with the National Electrical Code, NFPA 70, and Model Building Codes.

1.2 These requirements cover modules and panels intended for use in systems with a maximum system voltage of 1000 V or less.

1.3 These requirements also cover components intended to provide electrical connection to and mounting facilities for flat-plate photovoltaic modules and panels.

1.4 These requirements do not cover:

a)    Equipment intended to accept the electrical output from the array, such as power conditioning units (inverters) and batteries;

b)    Any tracking mechanism;

c)    Cell assemblies intended to operate under concentrated sunlight;

d)    Optical concentrators; or
