Abstract: A solar array integration system (AIS) and methods for mounting solar energy capture devices are provided. Such systems are useful for applications such as mounting photovoltaic (PV) modules to a suitable surface such as a rooftop. In one embodiment, the AIS includes a first row of tilted solar modules, a center spoiler coupled to the first row of tilted solar modules, the center spoiler is configured to deflect frontal airflow over the first row of tilted solar modules, and a second row of tilted solar modules, the second row of tilted solar modules being coupled to each other by an aerodynamic spar. The aerodynamic spar includes a deflector configured to deflect frontal airflow over the second row of tilted solar modules. The deflector may include a wedge-shaped profile. AIS can also include a third row of tilted solar modules, with an end spoiler coupled to the third row of tilted solar modules, and wherein the end spoiler is configured to deflect side airflow over the third row of tilted solar modules.
