A photovoltaic module can include an outer surface with an outwardly bulged convex shape. The outer surface can be curved about its longitudinal axis and/or transverse axis. Optionally, the outer surface can be bulged in a generally spherical shape. The convex shape of the outer surface of the PV module can provide the outer surface with additional stiffness, and/or cause water to flow away from the center of the panel toward its edges, thereby reducing soiling caused by accumulated water, debris, and dust and/or other benefits.
