1. A photovoltaic (PV) laminate comprising:
a first serpentine string of PV cells, the first serpentine string of PV cells having first and second linear arrays of a plurality of PV cells aligned along sequential legs of the first serpentine string of PV cells, the first and second linear arrays of PV cells electrically connected in series with each other, each of the PV cells of the first serpentine string having a light receiving surface; and
a second serpentine string of PV cells, the second serpentine string of PV cells having third and fourth linear arrays of a plurality of PV cells aligned along sequential legs of the second serpentine string of PV cells, the third and fourth linear arrays of PV cells electrically connected in series with each other, each of the PV cells of the second serpentine string having a light receiving surface,
wherein one PV cell of the first linear array of the first serpentine string is paired to one PV cell of the third linear array of the second serpentine string with a cross-tie electrical connection, the cross-tie connection forming a parallel electrical connection between the paired PV cells.
