1. A photovoltaic laminate comprising:
an array of photovoltaic cells, the photovoltaic cells each having a sun receiving face and a bottom face,
wherein each photovoltaic cell of the array of photovoltaic cells is electrically connected to one or more other photovoltaic cells of the array;
an encapsulant in contact with at least the sun receiving face or the bottom face of at least one photovoltaic cell of the array of photovoltaic cells;
a transparent layer positioned above the sun receiving face of photovoltaic cells of the array of photovoltaic cells; and
a single polymer composite positioned below the array of photovoltaic cells, the single polymer composite comprising a matrix and a reinforcement of the matrix, the matrix comprising a first polymer, having a first set of mechanical properties and the reinforcement of the matrix consisting of the first polymer and having a second set of mechanical properties, the first set of mechanical properties different from the second set of mechanical properties.
