A method of processing television content metadata in a communications system. The PV apparatus includes a plurality of photovoltaic modules arranged in an array and attached to a support structure which is attached to a roof. A cross-sectional height of the inner region measured perpendicularly to the wrap around shield’s media-facing end is less than a cross-sectional height of the second region, and a cross-sectional height of the middle region is greater than the cross-sectional height of the inner region and less than the cross-sectional height of the second region. A fault detection circuit is coupled to the plurality of line terminals and the plurality of load terminals.
