1.1 These requirements cover concentrator photovoltaic (CPV) modules and assemblies that concentrate
light on a target PV cell(s) for use in general and restricted areas in accordance with the unit’s installation
instructions. A CPV modlue is defined as any photovoltaic module which uses artificially elevated levels
(i.e. concentrated) of solar irradiance to produce electrical energy.
1.2 These requirements address concentrator photovoltaic (CPV) modules and assemblies intended for
installation in accordance with their installation instructions on or integral with buildings, or to be
freestanding (i.e. ground mounted or otherwise not attached to buildings), in accordance with the National
Electrical Code, NFPA 70, and model building codes.
1.3 The installation class for CPV modules and assemblies identifies the intended installation location as
either general access areas designated “General,” or restricted access areas designated “Restricted.”
General access units are able to be installed in open areas that may be contacted by the general public.
Restricted access units are to be installed in areas that prevent general public access such as a locked
and fenced in area.
1.4 These requirements cover CPV modules and assemblies intended for use in systems with a
maximum system voltage of 1500 V.
Exception: CPV modules that are constructed in the flate plate module format as defined by the Standard
for Flat-Plate Photovoltaic Modules and Panels, UL 1703, and with a concentration ratio of no more than
2 times shall be evaluated in accordance with all of the requirements in UL 1703.
