A higher performance loss rate (PLR) would lead to less energy generation over PV systems'' lifetime and hence financial losses. On the one hand, PV modules on floating platforms tend to operate at lower temperatures, which could directly translate into a longer lifetime (Jordan et al., 2016b, Kurtz et al., 2011).
The amount of solar radiation energy reflected by the device can have a substantial influence on this loss, which affects the efficiency of the solar cell as a whole. The typical loss of incident light from reflection from a silicon solar cell''s front surface is 30%, which lowers the efficiency of the device''s total power conversion ( Wang et ...
