Methods and devices are provided for reducing wasted space and capacity in solar module assemblies. In one embodiment, the method comprises mounting a plurality of modules onto at least one support rail to define a solar assembly segment wherein the solar assembly segment has a length of no more than about half the interior length of the shipping container used to ship the segment. The solar modules each have a weight less than about 20 kg and a length between about 1660 mm and about 1666 mm, and a width between about 700 mm and about 706 mm. In one embodiment, the length of the solar modules is limited by the longest support beam that may fit in a shipping container, which in one example is about 11,720 mm. The modules are also limited so that they can be limited to weighing no more than about 20 kg. In one embodiment, the module may be sized to provide at least 80 watts of power at AM 1.5 G. In another embodiment, the module may be sized to provide at least 90 watts of power at AM 1.5 G. In another embodiment, the module may be sized to provide at least 100 watts of power at AM 1.5 G. In another embodiment, the module may be sized to provide at least 110 watts of power at AM 1.5 G.
