Communications - Xylem Ai1 Series Quick Start Manual

For moving platforms, with two panels (i.e. 2x9W), the panel output must be de-rated by a further 50% to allow for
the rotation of the panels (as the panels cover only 180° of the possible 360° orientations). For moving platforms
with four panels (i.e. 4x9W) no further de-rating is required. In all configurations, the non-optimum panels do
receive some reflected energy resulting in the equivalent values shown in Table 4.
