1. A system, comprising:
a plurality of photovoltaic modules installed on a roof deck,
wherein the photovoltaic modules are arranged in an array on the roof deck,
wherein the array includes an upper surface,
wherein the array includes a first subarray,
wherein the first subarray includes a first side, a second side opposite the first side, an upper side extending from the first side to the second side, and a lower side extending from the first side to the second side,
wherein each of the photovoltaic modules includes
a first end and a second end opposite the first end,
at least one solar cell, and
a wire cover bracket located at the first end and configured to receive at least one electrical component,
wherein the wire cover brackets of the plurality of photovoltaic modules of the first subarray are configured to form a wireway on the first side of the first subarray;
a rapid shutdown device,
wherein the rapid shutdown device is electrically connected to the at least one electrical component,
wherein the rapid shutdown device is configured to reduce an electrical voltage of the system to a predetermined voltage level;
a transition box,
wherein the transition box is located above and adjacent to the wireway and above the upper side of the first subarray,
wherein the rapid shutdown device is located within the transition box;
and
at least one first visible indicator above the upper surface,
wherein the at least one first visible indicator is electrically connected to the plurality of photovoltaic modules,
wherein the at least one first visible indicator is activated when the electrical voltage of the system is less than or equal to the predetermined voltage level; and
at least one second visible indicator is located within the transition box,
wherein the at least one second visible indicator is electrically connected to the rapid shutdown device, and
wherein the at least one second visible indicator is activated when the rapid shutdown device is activated as a result of the electrical voltage of the system being less than or equal to the predetermined voltage level.
